15 AI Fundamentals Every Finance Pro Needs To Know
I still remember the night I realized I’d been doing it wrong. It was 11:47 p.m. — fluorescent lights buzzing, caffeine at illegal levels, and I was halfway through copy-pasting commentary from twelve different Excel tabs into a PowerPoint slide. I caught myself thinking, “There has to be a better way.”
There was. I just didn’t know it yet.
Fast forward a few months and I watched ChatGPT summarize a 2,000-line variance report in thirty seconds. Thirty. Seconds. No VLOOKUPs. No CONCATENATE formulas. No “Final_FINAL_v3(2).xlsx.”
That’s when it hit me: AI isn’t coming for our jobs — it’s coming for our tasks. And honestly, it can have them.
If you’re in finance right now, you’re probably feeling two things at once:
- Excitement — because AI is clearly powerful.
- Panic — because everyone keeps talking about tokens, embeddings, and “fine-tuning,” and you’re still trying to get your pivot tables to refresh without crashing.
You’re not alone. I built this guide to bridge that gap — to explain AI concepts and AI fundamentals for finance professionals, without the buzzword bingo, in plain English, with finance examples that actually make sense. Understanding these essentials can help you future-proof your career in finance and unlock new opportunities as AI transforms our industry.
We’ll start at the absolute beginning:
- What AI really is (and what it’s not).
- What a “large language model” even means.
- Why “tokens” matter when you’re paying per word.
What Even Is AI? (The Autocomplete That Ate the World)
Let’s start with the most overused, least-understood term in business right now: AI.
Artificial intelligence is a transformative technology that is reshaping modern finance by introducing fundamental AI concepts and technologies that underpin automation, analytics, and decision-making.
When most finance people hear generative AI, they picture some glowing brain in the cloud making million-dollar decisions. In reality? It’s just really fancy autocomplete.
If Excel formulas had a baby with your phone’s predictive text, and then fed it the entire internet — that’s AI. It doesn’t think the way you do. It doesn’t understand balance sheets or GAAP or why your CFO hates variance explanations longer than three sentences.
It simply predicts the next most likely word, number, or pattern based on everything it’s seen before.
That’s the secret. When you ask, “Summarize our Q2 performance,” it’s not actually “understanding” your business — it’s recognizing that when people say “Summarize Q2 performance” on the internet, the next sentence usually looks like “Revenue increased due to strong sales in X segment.”So it builds that kind of answer for you — just much faster (and with better grammar) than most analysts.
The Brain Behind the Curtain
AI, as we use it today in tools like ChatGPT or Microsoft Copilot, runs on something called a Large Language Model — or LLM. Think of it as an insanely well-read intern. It’s read thousands of annual reports, management letters, textbooks, and articles.
LLMs are built using machine learning models, natural language processing, and deep learning techniques, particularly neural networks, which enable them to process and generate human-like language. When you ask it a question, it doesn’t Google the answer — it generates one by pulling from the patterns it’s learned.
That’s why it can:
- Draft an executive summary in your tone.
- Reconcile commentary across cost centers.
- Or explain deferred revenue like you’re five years old.
But it’s also why it sometimes makes things up. Because it’s a pattern predictor — not a database. It’s autocomplete, not omniscient.
The Finance Parallel
If you’ve ever forecasted sales by dragging last year’s trend across next year’s months and adjusting for a few known events — congratulations, you’ve done predictive modeling.
AI just does that at massive scale, across text, numbers, and logic.
We predict a sales number.
AI predicts the next word.
Same math. Different medium.
Mini Exercise: Your First AI Test Drive
If you haven’t yet, open ChatGPT or Copilot in Excel and try this:
“Explain variance analysis like I’m five.”
Now try:
“Explain variance analysis like I’m a CFO.”
See the difference?
That’s pattern recognition in action.
The model tailors its language, tone, and complexity based on your context — not because it understands finance, but because it’s seen a million examples of how people talk about finance.
You’ve just done your first real AI experiment.
What’s a Large Language Model (LLM)?
The Brain That Ate the Internet (and Now Writes Your Commentary)
Now that we’ve established that AI is basically autocomplete on a caffeine drip, let’s talk about the brain behind it — the Large Language Model, or LLM.
If AI were Excel, the LLM would be the calculation engine.
If AI were a finance team, the LLM would be that one analyst who’s seen everything, remembers everything, and types way too fast.
So… what exactly is an LLM?
In simple terms:
An LLM is a type of neural network trained on text — billions (sometimes trillions) of words — so it can learn patterns in language and meaning.
Think of it like this:
You read one annual report and can summarize it.
The LLM has “read” millions of them.
So when you ask it to summarize one more, it already knows the rhythm, structure, and tone of a “summary.”
It doesn’t memorize content — it learns patterns.
That’s why it can write, translate, or reason across any topic you throw at it — even if it’s never seen your exact question before.
Metaphor: The World’s Smartest Autocomplete
Imagine Excel’s autocomplete feature — but instead of knowing a few formulas, it’s read every corporate report, management letter, and finance textbook on the internet.
Now, when you type:
“Our Q3 revenue growth was driven by…”
It already knows the next words are likely “pricing improvements, new customer acquisition, or volume expansion.”
That’s literally what an LLM does.
Predicts the next token (tiny chunk of a word) again and again — hundreds of times per second — until it finishes your sentence.
Under the Hood (Without the Math)
Here’s the 30-second version:
- Training: Engineers feed the model massive amounts of text (web pages, books, financial filings, code).
- Learning Patterns: It figures out which words tend to appear together and in what order.
- Fine-Tuning: Humans then teach it to sound more helpful, accurate, and polite (that’s why ChatGPT doesn’t swear… most of the time).
- Inference: When you ask it a question, it predicts the most likely response based on what it’s seen before.
That’s it. No secret server of accountants. No hidden Bloomberg terminal. Just math, patterns, and text.
Finance Example: How an LLM “Reads” a P&L
Let’s say you paste your income statement into ChatGPT and ask:
“Summarize our Q2 performance in three bullet points.”
Here’s what happens behind the scenes:
- Your text gets broken into tokens (little pieces of words).
- The model runs those through billions of pattern weights learned from similar data.
- It predicts what a good summary of that kind of text usually sounds like — “Revenue up X%, costs rose due to Y, net income improved.”
- Voilà — a summary that sounds intelligent but is really just math predicting meaning.
Pretty wild, right?
The same way you can smell an over-accrual in SG&A from three tabs away, the LLM can sense what a typical executive summary sounds like.
Mini Case Study: Month-End Commentary, Reinvented
A mid-sized SaaS finance team I worked with used to spend three days each month writing commentary for 25 cost centers.
They fed prior months’ commentaries and new P&L tables into ChatGPT with the prompt:
“Summarize key drivers by cost center in CFO-ready tone.”
The result: draft narratives in under five minutes — 80% usable, 20% polished by humans.
That’s the power of an LLM — not replacing you, but amplifying you.
What’s a Token (and Why You’re Charged for Them)?
The Currency of AI Conversations
If a Large Language Model is the brain, tokens are the neurons firing.
They’re the smallest chunks of language the model understands — little puzzle pieces that make up every word, sentence, and spreadsheet explanation you feed it.
Here’s the short version:
AI doesn’t read words. It reads tokens — fragments of words, punctuation, and symbols — and then tries to predict the next one.
So when you type:
“Revenue grew 10% in Q2 due to stronger sales.”
The model doesn’t see six words.
It might see something like this:
Human Words | AI Tokens |
|---|---|
Revenue | Re + venue |
grew | grew |
10% | 10 + % |
in Q2 | in + Q + 2 |
due to | due + to |
stronger sales | stronger + sales |
That sentence is about 13 tokens, not 6 words.
Think of tokens like syllables for machines — the smaller the pieces, the easier they can predict what comes next.
Metaphor: Tokens Are the Dollars You Spend to Talk to AI
Every token costs a fraction of a cent.
Each time you chat with ChatGPT, those tokens are the billable units.
So when you paste your 20-page variance analysis into a prompt and wonder why your API bill doubled — congrats, you’ve just fed your model a steak dinner.
Short prompts = cheaper, faster, easier.
Long prompts = expensive, slower, more confused.
You wouldn’t email your CFO a five-page explanation for a $300 variance.
Don’t do it to your AI either.
Why Tokens Matter in Finance
When using AI in finance, tokens control three critical things:
- Cost – You’re billed based on total tokens (input + output).
Example: feeding a 10,000-token PDF might cost $0.50–$1.00 on GPT-4 Turbo. - Context – Models can only “remember” so many tokens at once.
That’s called the context window. - GPT-4 Turbo: ~128,000 tokens (about 300 pages).
- Claude 3 Opus: up to 200,000 tokens (about 400 pages).
Once you exceed that? It forgets the beginning. - GPT-4 Turbo: ~128,000 tokens (about 300 pages).
- Claude 3 Opus: up to 200,000 tokens (about 400 pages).
Once you exceed that? It forgets the beginning. - Performance – More tokens = more noise. Clean, focused prompts give cleaner, faster answers.
Mini Finance Example: Feeding the Beast Wisely
Let’s say you want ChatGPT to summarize last quarter’s results.
Bad prompt:
“Here’s the entire 60-page PDF of our financial statements. Summarize key insights.”
That’s thousands of tokens — your model will choke.
Better prompt:
“Here’s our Q2 income statement. Focus only on revenue, COGS, and operating expenses. Summarize in 5 bullet points.”
Now it’s shorter, cheaper, faster — and way more accurate.
It’s the same discipline we use in FP&A: don’t throw everything at the model, feed it what matters.
Mini Exercise: Estimate Your Token Use
Try this free token counter: tiktokenizer.vercel.app
Copy and paste a paragraph from your last variance report.
See how many tokens it is.
Then delete half the fluff and check again — that’s instant savings.
How AI Actually Works (Without the Math or Headaches)
What Happens Between “Hey ChatGPT” and “Here’s Your CFO Summary”
Okay, so now we know two things:
- AI isn’t magic — it’s predictive text on a protein shake.
- It speaks in tokens, not words.
But how does it actually do the thing?
How does your “Summarize Q2” prompt go from plain text → machine logic → professional-sounding narrative that’s somehow better than the one you wrote last month?
Let’s break it down — step by step, no math required.
Step 1: You Ask a Question (The Prompt)
Everything starts with your input — the prompt.
Think of it as sending an email to your intern.
If you say “Make me a chart,” they’ll stare blankly.
If you say “Create a line chart showing revenue vs. budget for Q1–Q3,” they’ll know exactly what to do.
AI works the same way.
The clearer the question, the smarter the answer.
Step 2: It Breaks Your Prompt into Tokens
Before the model can “think,” it needs to translate your words into machine-speak — tiny chunks of text called tokens.
Your question —
“Summarize the income statement and highlight major cost variances.”
— becomes something like 15–20 tokens.
The model has been trained on billions of token patterns, so it instantly recognizes,
“Ah, this looks like the kind of text that ends with bullet points or sentences explaining numbers.”
Step 3: It Predicts the Next Token
Here’s where the magic happens.
The model doesn’t “look up” the answer — it predicts it, one token at a time.
Imagine your brain playing autocomplete:
You read “Revenue grew…” and immediately think “10%.”
That’s prediction.
The model does this millions of times per second.
Every token it outputs becomes part of the next prediction — like a rolling snowball of meaning.
Each prediction is scored based on probability, and the model picks the most likely one… with a sprinkle of randomness so it doesn’t sound robotic.
Step 4: It Reruns the Pattern — Thousands of Times
AI repeats this “predict next token” process until it completes your answer — usually when it hits a stop token (like a period or end of instruction).
For a 100-word summary, that might mean 120–150 predictions, each building on the last.
It’s like watching an analyst build a report line by line, except this one does it faster than your coffee machine finishes brewing.
Step 5: You Get the Output (The Answer)
The tokens get stitched back together into human-readable language:
“Revenue increased 8% in Q2 driven by higher pricing and volume. SG&A rose due to marketing spend. Net income improved by 3 points.”
Voilà.
You didn’t just “get” that answer — the model built it token-by-token from scratch.
Every bullet, every percent, every transition word — predicted from patterns it’s seen thousands of times before.
Finance Metaphor: Your AI as a Forecasting Model
If you think about it, this isn’t so different from what you already do in FP&A.
- You feed your model historical data.
- It identifies patterns.
- It projects the next period.
AI just does it with language instead of numbers.
It’s running a forecast of words, not revenue.
So when you ask it for a board summary, it’s essentially predicting what a “typical” board summary sounds like for the situation you described.
Why This Matters
Understanding how AI “thinks” helps you design better prompts.
If it’s guessing the next token based on context:
- Give it the right context (e.g. “You are a senior FP&A analyst at a SaaS company”).
- Set the right goal (e.g. “Summarize in 3 CFO-ready bullets”).
- And limit noise (e.g. only paste relevant data).
That’s how you go from generic fluff to tailored, on-brand finance output.
Mini Exercise: Watch It Think
Next time you type a question in ChatGPT, click the three dots → View Raw Response (or API log) if available.
You’ll see the tokens appear word by word, like a slow typewriter.
That’s your AI thinking in public.
It’s not recalling — it’s predicting.
What AI Can Actually Do for Finance
The Five Superpowers Every Analyst Wishes They Had
Now that you know what’s happening behind the curtain, let’s talk about what this thing can actually do.
Because let’s be honest — you don’t care about token probabilities. You care about getting your damn reports out faster, writing better commentary, and maybe not working past 8 p.m.
AI solutions and services, such as those offered through cloud platforms, provide practical applications in finance—like automating reporting, streamlining workflows, and enhancing data analysis. Leveraging these AI solutions and services allows finance professionals to realize the full potential of AI, with the benefit of saving time, improving accuracy, and advancing their careers.
Here’s the good news: modern AI models like ChatGPT, Claude, and Copilot are already capable of doing about 80 % of the grunt work that keeps finance pros glued to their spreadsheets.
Below are the five big categories of what AI can do for us right now — no futuristic hype, no self-driving robots, just real, practical finance wins.
1. Summarize
What it does: turns long, messy text into concise explanations.
Metaphor: your over-caffeinated intern who reads everything and hands you the executive summary.
Finance examples:
- Condensing a 40-page variance commentary into 5 bullet points.
- Summarizing earnings calls or management reports.
- Creating 1-sentence KPI takeaways for dashboards.
Pro tip: ask for structure.
“Summarize this report in 3 bullet points: revenue, costs, net income.”
Structured prompts = usable output.
2. Classify
What it does: sorts messy inputs into organized buckets.
Metaphor: the world’s fastest AP clerk — but one that never asks, “What GL code is this again?”
Finance examples:
- Categorizing expense descriptions (“client dinner,” “software,” “travel”).
- Tagging commentary lines by driver (“volume,” “price,” “mix”).
- Grouping open-ended survey responses for FP&A feedback.
Pro tip: give examples in your prompt.
“If the description includes ‘Uber’ or ‘taxi,’ classify as Travel.”
3. Calculate + Analyze
What it does: performs calculations, sanity checks, and finds patterns — especially when paired with Excel or Python.
Metaphor: the analyst who doesn’t just crunch numbers but actually explains them.
Finance examples:
- Compute YoY and QoQ variances directly from pasted tables.
- Identify biggest cost drivers in an uploaded dataset.
- Translate formulas or DAX expressions into plain English.
Pro tip: always verify numeric results — AI is good at math but bad at units and rounding.
4. Generate
What it does: writes new content in your tone — commentary, memos, emails, PowerPoint bullets, you name it.
Metaphor: your personal ghostwriter who actually meets deadlines.
Finance examples:
- Draft month-end variance commentary.
- Write forecast rationale paragraphs.
- Create CFO talking points from raw data.
Pro tip: include your style guide.
“Write in the tone of a senior FP&A manager presenting to the CFO: concise, factual, no fluff.”
5. Explain + Translate
What it does: converts complexity into clarity.
Metaphor: your bilingual colleague who speaks both “Excel” and “Executive.”
Finance examples:
- Explain a financial concept (“What is deferred revenue?”).
- Translate accounting policies into plain English.
- Turn SQL queries or Python scripts into natural-language summaries.
Pro tip: use “Explain like I’m…” prompts to control tone.
“Explain cash flow from operations like I’m a new analyst.”
Mini Case Study: The 2-Day Close Commentary Miracle
One FP&A team I worked with spent two full days every month drafting commentary for each business unit.
They fed prior months’ commentaries and the latest P&L tables into ChatGPT using a structured prompt:
“Using the table below, summarize performance by cost center in CFO-ready tone.
Keep each summary under 100 words.”
Result?
- First drafts for 20 cost centers generated in under 15 minutes.
- Analysts spent the rest of the time refining insights — not formatting sentences.
- Close cycle shaved down by 10 hours.
Not bad for a model that technically just predicts words.
What AI Can’t Do (Yet) — and How to Catch It When It’s Wrong
Your Smartest (and Most Confidently Wrong) Intern
By now you’re probably thinking,
“If AI can summarize, calculate, and write commentary, what do we even need humans for?”
Don’t panic — your job is safe.
Because while AI is incredibly smart, it’s also a world-class BS artist.
The Problem: It Doesn’t Know, It Just Predicts
AI isn’t looking up facts or checking formulas.
It’s guessing the next most likely token — the same way you finish a sentence in your head.
That’s why it can generate perfect-sounding nonsense.
It’s not lying; it just doesn’t know it’s wrong.
Metaphor: imagine your intern drafting a board memo based purely on vibes.
Looks great. Sounds great.
Totally wrong.
Four Ways AI Screws Up (and How to Catch It)
1. Hallucinations
What happens: the model invents numbers, sources, or details that don’t exist.
Example: you ask, “Summarize drivers of gross margin,” and it replies,
“Margins improved due to lower freight costs,”
even though your company sells SaaS.
Fix: always verify any quantitative or factual claim against source data.
2. Outdated Data
What happens: public models like ChatGPT don’t know what happened yesterday (or even last fiscal year).
They’re trained on snapshots of the internet, not live data.
Example: it confidently quotes “2022 guidance” when you ask about 2025 performance.
Fix: give it the data yourself. Paste, upload, or connect via Copilot/Power BI.
3. Weak Numerical Precision
What happens: AI is fluent in language, not math. It can add, but don’t let it build your forecast.
Example: 2 + 2 = 4, sure. But 8.2 % × 19.5 M + FX impact? Expect “rounding errors.”
Fix: let Excel, Power BI, or Python handle the math; let AI handle the narrative.
4. Missing Context
What happens: AI can’t read your mind (yet). If you don’t tell it what kind of company you are, it’ll assume you’re Amazon.
Example: you ask, “Explain revenue drop,” and it blames seasonality… even though you run a B2B subscription business.
Fix: set context in every prompt.
“You are a senior FP&A analyst at a SaaS company. Explain the revenue drop below.”
Mini Case Study: The Phantom Freight Story
A consumer-goods company used ChatGPT to draft monthly commentary.
The AI wrote,
“Freight costs decreased due to improved carrier rates.”
Problem? They had no freight line item. The model saw “COGS variance” and hallucinated a common cause it had seen online.
They almost sent it to the CFO.
Lesson learned: AI can’t fact-check itself — but you can.
The 3-Step “Trust-But-Verify” Process
- Spot-Check Numbers
Compare outputs to source data every time.
(If you wouldn’t sign it, don’t send it.) - Ask for Sources or Reasoning
Add this to your prompt: - “Show your reasoning before the final answer.”
It forces the model to explain its logic step-by-step. - Keep a Human Review Loop
Use AI to draft, not to decide.
You review, revise, and approve — same as you would with a junior analyst.
Picking the Right AI Tool for Finance
Because “ChatGPT” Isn’t the Only Game in Town (Even If It Feels Like It)
At this point, you might be wondering:
“Okay, Mike, I get it. AI’s cool, but which one should I actually use?”
Fair question. Because the AI world right now feels like walking into Costco without a list — everything looks amazing until you realize you only needed one thing and accidentally subscribed to five.
Here’s the truth: not all models are created equal.
Each one has its strengths, quirks, and ideal use cases.
And as a finance pro, picking the right model is like picking the right Excel function — use the wrong one, and your results get weird fast.
Meet the Models
Below are the four major players you’ll run into most often — all capable, all slightly different. Think of them as the “Big Four” of AI (minus the billable hours).
Model | Best For | Why You’ll Love It | Why It Might Annoy You |
|---|---|---|---|
ChatGPT (OpenAI) | Narrative writing, data analysis, Excel logic | Most balanced and fluent; great at financial storytelling | Occasional hallucinations; paid tiers required for advanced tools |
Claude (Anthropic) | Reading long docs, internal policies, 10-Ks | Handles massive context windows (up to 200k tokens) | Slower response, sometimes too cautious |
Gemini (Google) | Integrations, live search, multimodal tasks | Can pull fresh data + read charts, PDFs, images | Early ecosystem — still uneven for enterprise use |
Microsoft Copilot | Excel, PowerPoint, Teams, Outlook | Built into your daily finance stack; no copy-pasting | Limited creativity; works best with clean data models |
The Right Tool for the Job
Just like you wouldn’t use a pivot table to run a Monte Carlo simulation, you shouldn’t use the same AI model for every task.
Here’s how I think about it:
🧠 Strategic Thinking / Narrative Work → ChatGPT
When you need help explaining, summarizing, or writing — this one’s your guy.
Think variance commentary, FP&A memos, management decks.
It’s the model with the best “voice.”
Prompt example:
“Write a 3-sentence CFO summary for this table. Use a confident, data-driven tone.”
📄 Policy, Audit, or Long Reports → Claude
Claude is like the senior manager who actually reads the documentation.
It can process entire 10-Ks or policy manuals without breaking a sweat.
Perfect for audit teams or controllers reviewing long, dense text.
Prompt example:
“Summarize all mentions of ‘impairment testing’ in the attached accounting policy.”
🔍 Real-Time or Visual Data → Gemini
Gemini’s sweet spot is fresh information and visual understanding.
It can interpret uploaded images or charts and answer follow-up questions about them.
Useful for trend commentary or dashboard reviews.
Prompt example:
“Here’s our revenue chart. Describe the trend and call out anomalies.”
💼 Embedded Workflow Automation → Microsoft Copilot
Copilot is the “inside job” — it lives inside Excel, Word, PowerPoint, Teams, and Outlook.
It’s your AI coworker, not an external chatbot.
If your company is all-in on Microsoft 365, this is where the productivity gold lives.
Prompt example:
“In this workbook, highlight cost centers where expenses exceeded budget by more than 10 % and summarize the drivers.”
Pro Tips for Choosing Wisely
- Match the model to the task.
Writing? → ChatGPT.
Reading? → Claude.
Visuals? → Gemini.
Inside Office? → Copilot. - Watch for data privacy.
Don’t upload confidential financials into public tools — use enterprise or sandbox versions. - Don’t chase shiny objects.
The “best” model is the one that fits your workflow — not the one with the most YouTube hype.
Mini Case Study: The $1,200 Copy-Paste Problem
A corporate FP&A manager at a manufacturing firm was using ChatGPT Plus to summarize 100-page PDFs of plant results every month.
Each upload was hitting token limits and racking up costs.
They switched to Claude, which could read the entire report in one go — cost dropped by 90 %, and summaries actually got better.
Moral of the story: sometimes the right model isn’t the flashiest; it’s the one built for your use case.
Prompting Like a Pro
How to Talk to AI So It Stops Acting Like an Overeager Intern
Here’s the secret no one tells you about AI:
The difference between “Wow, this thing is incredible” and “This thing is useless”
usually comes down to how you ask.
AI doesn’t read your mind — it reads your prompt.
And most people write terrible prompts.
If you’ve ever said,
“ChatGPT just gives me generic nonsense,”
that’s because you’re prompting like a human talking to a friend, not like a manager giving an assignment.
You wouldn’t tell a new analyst, “Hey, make something insightful.”
You’d say, “Pull revenue by region, compare to budget, and give me three bullet points explaining the variance.”
That’s prompting.
The Golden Rule: Clarity In = Clarity Out
The AI isn’t creative — it’s obedient.
It will give you exactly what you ask for… even if what you asked for was vague garbage.
So instead of writing this:
“Summarize this report.”
Try this:
“You are a senior FP&A analyst. Summarize this Q2 income statement in three CFO-ready bullet points: one for revenue, one for costs, one for net income. Use a confident, professional tone.”
That one change can be the difference between “🤖 random essay” and “✨ near-perfect executive summary.”
My Favorite Prompt Formula: The 5-Part Framework
Here’s the structure I use every day — whether I’m writing commentary, generating insights, or prepping a board deck.
Step | What It Means | Example |
|---|---|---|
1. Role | Tell the model who it’s pretending to be. | “You are a senior FP&A analyst.” |
2. Task | Explain the job clearly. | “Summarize Q2 results for the CFO.” |
3. Context | Give it background info or data. | “Here’s the income statement for Q2 (paste data).” |
4. Format | Tell it how to structure the answer. | “Use 3 bullet points: revenue, costs, net income.” |
5. Tone | Set the voice or personality. | “Confident, concise, executive tone.” |
That’s it. Five parts.
Treat it like a job brief, not a wish.
Metaphor: The AI as Your Junior Analyst
If you walk over to your analyst’s desk and say,
“Hey, make a slide about Q2,”
you’ll get… whatever’s on their mind.
But if you say,
“Build one slide comparing actual vs. budget for revenue and margin. Use bullets, not paragraphs,”
you’ll get something usable.
AI is the same way — except it never sighs or forgets the logo alignment.
Real Finance Examples
Example 1: Month-End Commentary
Bad Prompt:
“Write commentary for this P&L.”
Better Prompt:
“You are a senior FP&A analyst at a SaaS company. Using the table below, summarize Q2 performance in 3 bullet points for the CFO. Focus on revenue, costs, and profit. Use clear, data-backed language and avoid filler words.”
Example 2: Budget Variance Summary
Bad Prompt:
“Explain this variance.”
Better Prompt:
“You are a finance manager presenting at the budget review. Explain why actual expenses exceeded budget for marketing by 15%. Include two likely drivers and one potential follow-up question for the team.”
Example 3: Forecast Commentary
Bad Prompt:
“Give me some ideas for Q4 forecast.”
Better Prompt:
“You are an FP&A lead preparing the Q4 forecast. Suggest 3 scenario drivers based on prior trends: one optimistic, one conservative, and one base case. Present them in a simple table with driver, assumption, and expected impact.”
Mini Case Study: From Fluff to CFO-Ready
A retail finance team used ChatGPT to generate monthly summaries, but leadership hated them — “too fluffy, not enough substance.”
We added structure to the prompt:
“You are a finance analyst preparing the monthly executive report. Summarize key P&L movements by category, using 1 bullet each for revenue, costs, and EBITDA. Include % vs. budget and plain-English driver explanations.”
Result: AI-generated drafts that needed minimal editing — and a CFO who started asking,
“Who wrote this? It’s actually good.”
Pro Tips for Power Prompting
- Be specific about the audience. (CFO vs controller vs analyst = different tones.)
- Give examples of what “good” looks like. (“Here’s last month’s summary — follow this format.”)
- Add constraints. (“Keep it under 100 words.”)
- Ask for iterations. (“Now rewrite in a more conversational tone.”)
The more feedback loops you run, the smarter the output gets — just like coaching a new team member.
Giving AI Context — Feeding It the Right Data
If You Don’t Tell It What You Know, It’ll Make Something Up
Here’s the truth about AI: it’s not smart, it’s well-trained and clueless.
Every time you start a new chat, it has zero idea who you are, what company you work for, or why your CFO is allergic to adjectives.
If you don’t feed it context, it will happily assume you’re Apple. Or Tesla. Or a lemonade stand — whatever pattern fits best.
And that’s when you get answers that sound polished but totally wrong.
Why Context Matters
When you ask,
“Summarize our Q2 performance,”
the model doesn’t know your business model, your cost structure, or your reporting format.
So it guesses.
But when you say,
“You are a senior FP&A analyst at a B2B SaaS company. Here’s the income statement for Q2. Focus on ARR growth, churn, and CAC efficiency,”
suddenly the response gets sharp, specific, and eerily relevant.
That’s not coincidence — that’s context.
The 3 Levels of Context You Can Feed AI
1. Role Context — Who It Should Pretend to Be
Always start with a role.
You’re basically casting your AI in a play.
Example:
“You are a finance manager presenting to the CFO.”
or
“You are an accounting lead preparing audit notes for external reviewers.”
This changes tone, vocabulary, and level of detail.
2. Data Context — What It Should Work With
This is your real-world input: tables, commentary, policies, or KPIs.
AI can’t reason about numbers it doesn’t see — so feed it your data directly (when allowed).
Example prompt:
“Using the table below, summarize key movements in revenue and costs. Highlight YoY variance above 10 %.”
If you’re in Copilot or ChatGPT Advanced Data Analysis, you can even upload CSVs or Excel files instead of pasting text.
Pro tip: clean your data first.
If your table looks like it survived a data hurricane, the AI won’t perform miracles.
3. Instructional Context — How You Want It to Respond
This is the piece most people skip.
You have to tell the model how to format the answer.
Example:
“Respond with 3 bullet points: one for revenue, one for costs, one for profit. Keep it under 100 words.”
Boom — clarity and consistency.
Metaphor: AI as Your New Analyst
If you hired a new analyst and said,
“Write commentary,”
they’d freeze.
But if you gave them:
- the P&L
- the prior month’s commentary
- and told them who’s reading it
you’d get a solid draft on the first try.
AI works exactly the same way — it just doesn’t ask follow-up questions (which is both convenient and terrifying).
Mini Finance Example: Context Makes or Breaks It
Let’s test it.
Prompt A (no context):
“Summarize the income statement.”
Result:
“Revenue increased due to strong sales performance. Expenses rose slightly. Profit improved.”
Looks fine — until you realize it could apply to literally any company on Earth.
Prompt B (with context):
“You are a senior FP&A analyst at a subscription software company. Using the income statement below, summarize key changes in ARR, churn, and gross margin for the CFO. Keep it under 100 words.”
Now the answer sounds like it came from your team — not a textbook.
How to Feed Context Safely
Before you go pasting your company’s financials into ChatGPT, pause.
Here’s how to do it the smart way:
- Check the tool type.
- Public tools (ChatGPT.com, Gemini): never paste sensitive data.
- Enterprise versions or Copilot: safer, built for business data.
- Public tools (ChatGPT.com, Gemini): never paste sensitive data.
- Enterprise versions or Copilot: safer, built for business data.
- Anonymize or aggregate.
Replace numbers or names if needed (“Company A,” “Revenue = $X”). - Use private data connections (like Power BI + Copilot or ChatGPT Teams).
That keeps your info inside your company’s walls.
Remember: your AI doesn’t need everything.
It just needs enough to reason correctly.
Mini Case Study: The $10K “Context” Fix
A corporate FP&A team was paying consultants to “train” an AI to write monthly variance commentary.
Turns out, they didn’t need training — they just needed context.
Once they added:
- Prior month’s commentary
- The raw P&L
- And a prompt that set role, task, and format
Their accuracy jumped from 50 % to 90 %.
Zero custom coding. Just better instructions.
Retrieval-Augmented Generation (RAG): Your AI With a Filing Cabinet
How to Stop Your AI From Guessing and Make It Read the Damn Policy Binder
So far, we’ve taught the AI to act like a brilliant intern — one that’s fast, articulate, and occasionally full of it.
Now it’s time to give that intern a filing cabinet.
That’s basically what Retrieval-Augmented Generation, or RAG, does.
It lets the AI look things up before it answers — using your company’s actual data, not whatever it remembers from the internet.
In Plain English: What RAG Actually Is
When you ask ChatGPT a question, it’s pulling from memory — the patterns it learned during training.
That’s like asking a finance analyst to explain GAAP without letting them open the accounting manual.
RAG changes that.
It works like this:
- Retrieval → The model searches a connected document store (your SharePoint, Drive, data lake, etc.) for relevant files or snippets.
- Augmentation → It feeds those snippets into the prompt as fresh context.
- Generation → Then it writes an answer based on that material — not its imagination.
Result: it cites real sources and stops hallucinating (mostly).
Metaphor: AI + Filing Cabinet
Think of your AI as a new finance hire.
Without RAG, they’re bluffing in meetings.
With RAG, they’re flipping through last quarter’s decks, 10-Ks, and commentary binders before they speak.
That’s the difference between “sounding smart” and being useful.
Why Finance Teams Need RAG
Finance runs on documentation — policies, templates, assumptions, commentary, board decks.
All that knowledge lives in random folders across your company.
RAG turns it into something you can query in plain English.
Example Use Cases
- Ask:
- “What are the capitalization rules for software development costs?”
And the model replies:
“Per our 2023 Accounting Policy Manual, section 4.3, development costs can be capitalized once technical feasibility is established.” - Or:
- “Summarize all comments about margin pressure in last quarter’s commentary documents.”
It scans 20 Word files, finds the references, and summarizes them. - Or:
- “What assumptions changed between the FY24 and FY25 forecasts?”
It reads both decks and lists the deltas.
That’s not “AI magic.” That’s RAG doing a document lookup + summary faster than any intern ever could.
Step-by-Step: How a Simple Finance RAG Workflow Works
You don’t need to code — tools like ChatGPT Team, n8n, and Microsoft Copilot already use RAG behind the scenes.
But here’s the mental model:
- Store your files somewhere searchable.
(OneDrive, SharePoint, Google Drive, or a simple folder.) - Index the content.
The system creates “embeddings” — numerical fingerprints of each paragraph. - Ask a question.
The AI retrieves the most relevant passages from your indexed files. - Generate an answer.
It combines those passages into a human-readable summary — citing where each fact came from.
Congratulations — you’ve just built a mini “Finance Copilot” without realizing it.
Mini Case Study: Policy Lookup Without Panic
A controller at a mid-size tech firm spent hours every quarter digging through 60-page accounting manuals to confirm treatment of deferred revenue.
Their IT team set up a simple RAG bot using n8n + ChatGPT: it indexed the policy PDFs and pulled answers instantly.
Now, instead of flipping through binders, the controller asks:
“What’s our revenue recognition policy for multiyear SaaS contracts?”
The bot replies with the exact paragraph and citation.
Response time: 10 seconds.
Error rate: near zero.
Pro Tips for Finance RAG Projects
- Keep your sources clean. Garbage in, garbage out. Index final versions, not drafts.
- Tag and label documents. The more structured your folders, the smarter your search results.
- Add human review. Even with RAG, confirm the answer before it hits an external report.
- Start small. One process (like policy lookup or commentary search) is plenty to prove ROI.
Embeddings — How AI “Remembers” Meaning
The Secret Sauce Behind Smart Search (and Why It’s Like Your Chart of Accounts)
If Retrieval-Augmented Generation (RAG) is the filing cabinet, embeddings are the labels on each folder — the thing that tells the AI what’s inside before it opens it.
They’re how your AI “remembers” meaning, not just words.
So, What the Heck Is an Embedding?
When you upload a file, the AI doesn’t store it as text.
It converts every sentence into a long list of numbers — a “vector.”
Those numbers capture the essence of what that sentence means.
Think of it like a GPS coordinate for language.
Two sentences that mean similar things end up near each other in that mathematical space.
For example:
- “Revenue increased due to higher pricing.”
- “Sales grew because of a price hike.”
Different words, same idea — so their embeddings are neighbors.
That’s how AI can find related paragraphs even when you phrase things differently.
Metaphor: Your Chart of Accounts
If you’re a finance person, you already get this.
Embeddings are like your chart of accounts — they organize chaos.
Imagine if your GL didn’t have account numbers.
Everything would be dumped in “Miscellaneous Expense” and you’d never find anything again.
Embeddings do the same thing for text.
They assign every phrase its own “account code,” so when you ask,
“Show me past commentary about margin pressure,”
the AI knows which sentences fall in that “account category,” even if the words don’t match exactly.
How Embeddings Power Smart Search
Here’s what happens when you query an AI system that uses embeddings (like a RAG pipeline):
- Your question gets embedded — turned into a vector (a list of numbers).
- The AI compares that vector to all the vectors from your stored documents.
- It finds the closest matches — the snippets whose “meaning” is most similar to your query.
- It returns those snippets as context for the model to read.
That’s why when you type,
“What’s our lease accounting policy?”
It finds the exact paragraph titled “Operating vs. Finance Leases” — even if the word “policy” never appears there.
Finance Example: Commentary Search
Let’s say you’ve got two years of month-end commentary saved in a shared drive.
Each file’s full of lines like:
- “Margins compressed due to input cost inflation.”
- “COGS increase driven by supplier pricing.”
- “Raw material prices eased in Q2.”
You could manually read them all (please don’t).
Or you could embed them and ask:
“Find past commentary about material cost changes.”
The AI instantly pulls the relevant sentences — even though none of them literally say “material cost changes.”
That’s embeddings doing the heavy lifting.
Mini Case Study: Audit Prep in Half the Time
A manufacturing controller used to spend days combing through prior-year audit files to find evidence for a “significant estimates” disclosure.
They built a simple embedding search in ChatGPT Teams: all audit memos were indexed once.
When the next audit rolled around, they typed:
“Find last year’s discussion of inventory obsolescence reserves.”
The AI returned three excerpts with file names and page numbers in under a minute.
Total time saved: two days.
Zero hallucinations.
Pro Tips for Working with Embeddings
- Keep chunks small. Split long documents into sections or paragraphs before embedding.
- Label your files. Include metadata like “source: FY24 audit memo” or “author: FP&A.”
- Update periodically. If your policies change, re-embed them so your search stays accurate.
- Use secure storage. Embeddings are derived from your text — treat them like sensitive data.
Fine-Tuning — Teaching AI Your Company’s Language
Because “Operating Income” ≠ “EBIT,” and Your CFO Cares About the Difference
By now, you’ve learned how to feed AI your context and even give it a filing cabinet (RAG). But what if you could go one step further — and teach it your company’s language?
Formal AI courses, led by expert instructors, provide students with the foundational skills needed to understand and apply artificial intelligence in real-world scenarios. These courses often have prerequisites to ensure students are prepared for advanced topics, and successful completion can lead to a certificate or industry-recognized certification. Earning such certification helps students gain valuable credentials that support professional development and career advancement in finance and related fields.
That’s what fine-tuning does. It’s like sending your AI to corporate bootcamp.
In Plain English: What Fine-Tuning Really Means
When you fine-tune, you’re not retraining the whole model (that would take a data-center and Jeff Bezos’s wallet).
You’re teaching it specific patterns — tone, phrasing, terminology, and logic — by giving it a small, curated dataset of examples.
Think of it like onboarding a new analyst with your “best of” folder:
- Past CFO memos that nailed the tone.
- Month-end commentary written by your A-player.
- Forecast templates that always passed audit.
Feed those into a fine-tuning pipeline, and the model learns:
“At this company, we say ARR, not revenue. We write ‘margin expanded 80 bps,’ not ‘profits went up.’ We close with ‘Next Steps,’ not ‘Conclusion.’”
After that, every response it generates sounds like you.
Metaphor: The Corporate Accent Coach
Generic AI speaks “business English.”
Fine-tuned AI speaks your dialect of finance.
It learns that your CFO hates adjectives, your CEO loves metaphors, and your head of FP&A still insists on “Operating EBITA (before SBC).”
It doesn’t argue — it adapts.
Why Fine-Tuning Matters in Finance
Finance teams rely on consistency: the same terms, same structure, same tone, every month.
Generic AI can write a commentary.
Fine-tuned AI can write your commentary.
Examples:
- Your standard format: 3 bullets (Revenue, Costs, Profit).
- Your preferred phrasing: “favorable vs. budget” instead of “above target.”
- Your metrics: EBIT, FCF, and NRR — not “earnings” or “cash flow.”
Fine-tuning bakes those rules into the model.
Now everyone sounds like they belong on your team.
How It Works (Without the Tech Headache)
- Collect examples.
20–100 high-quality samples of your “ideal” outputs — commentary, memos, Q&A, forecasts. - Clean the data.
Remove private info, placeholders, and formatting errors. - Map inputs to outputs.
For each sample, pair the prompt (what you asked for) with the desired answer (the gold-standard response). - Train a copy of the model.
Tools like OpenAI, Anthropic, and Hugging Face handle the rest. - Test and refine.
Run real prompts. Check tone, accuracy, and consistency. Iterate.
After that, your AI “knows” your company style — no retraining every conversation.
Mini Case Study: The CFO Style Guide Bot
A global SaaS company fine-tuned a small GPT-3.5 model on 200 pieces of prior board commentary.
Before fine-tuning: the AI wrote generic updates like,
“Revenue grew due to strong sales.”
After fine-tuning:
“ARR increased 12 % QoQ, driven by enterprise renewals and pricing expansion in EMEA.”
Same prompt. Same data. Completely different voice.
They cut editing time by 70 %.
Now their “AI analyst” sounds like it’s been working there for years.
Fine-Tuning vs. Prompting vs. RAG
Here’s how to think about it:
Approach | What It Teaches | Best For | Analogy |
|---|---|---|---|
Prompting | Task-specific direction | Quick, one-off jobs | Giving clear instructions |
RAG | Knowledge lookup | Using internal docs | Letting AI “read the files” |
Fine-Tuning | Company-specific tone & phrasing | Ongoing outputs (reports, memos) | Sending AI to “Finance Finishing School” |
Use prompting for flexibility, RAG for accuracy, and fine-tuning for personality.
Pro Tips for Finance Teams
- Start with tone. Fine-tune first on writing style, then on data tasks.
- Protect confidentiality. Use sanitized samples or enterprise environments.
- Don’t overtrain. 50 great samples beat 500 mediocre ones.
- Keep humans in the loop. The model writes; you still approve.
Chain of Thought & Multi-Step Reasoning
How to Make AI Think Before It Speaks (a Skill Some Analysts Still Haven’t Mastered)
If you’ve ever asked ChatGPT a tough question like,
“Why did net income drop when revenue went up?”
and it confidently spat out an answer that sounded right but wasn’t,
you’ve seen what happens when AI skips its homework.
That’s because by default, AI tries to answer fast, not right.
It jumps straight to conclusions — like a new analyst eager to impress the CFO.
The fix?
Make it show its chain of thought.
In Plain English: What “Chain of Thought” Means
Chain of Thought (CoT) is just a fancy way of saying:
“Explain your reasoning step-by-step before giving the final answer.”
It’s a simple trick with huge impact.
When you ask the model to think out loud, it slows down, reasons through the problem, and double-checks itself before speaking.
Metaphor: The Analyst Who Talks Through Their Math
Imagine reviewing a forecast with two analysts.
- Analyst A blurts, “Operating income’s down 6% because costs went up.”
- Analyst B says,
- “Let’s check revenue first — up 10%. COGS rose 14%, driven by freight. Opex flat. So yes, margin compression explains the drop.”
Who do you trust?
Exactly.
Chain of Thought turns your AI into Analyst B.
Why This Matters for Finance
Finance questions almost always require multi-step logic:
- Compare actual vs. budget.
- Identify which line items moved.
- Quantify impact.
- Translate it into narrative.
Without guidance, the model might skip half those steps.
With Chain of Thought, it walks through each one — and the accuracy skyrockets.
How to Use Chain of Thought in Prompts
Just add one simple phrase:
“Think through this step-by-step before answering.”
or
“Show your reasoning before giving the final response.”
Then sit back and watch the AI break the problem down like a pro.
Example 1: Variance Explanation
Prompt (basic):
“Explain why Q2 net income decreased.”
Result:
“Net income decreased due to higher costs.” (Thanks, Sherlock.)
Prompt (CoT):
“You are an FP&A analyst. Think step-by-step: review revenue, COGS, Opex, and non-operating items before explaining why net income decreased.”
Result:
- Revenue increased 5%.
- COGS increased 8% (primarily raw materials).
- Opex flat.
- Interest expense up 2 points.
Final: Net income fell 3 points due to higher input costs and interest expense.
Now that’s usable commentary.
Example 2: Forecast Adjustment
Prompt (CoT):
“You are preparing the Q4 forecast. Think step-by-step: identify last quarter’s key variance drivers, then propose how they might continue or reverse next quarter.”
Result:
- Marketing underspent 10%.
- Revenue growth exceeded plan by 6%.
- Expect partial normalization next quarter.
Final: Forecast adjusted upward 3% for Q4 revenue, maintaining conservative expense targets.
The model just simulated your reasoning process — in seconds.
Mini Case Study: Audit QA Bot
An internal audit team used AI to cross-check policy compliance in procurement transactions.
At first, results were inconsistent — the model flagged issues randomly.
They added a simple Chain of Thought prompt:
“Before labeling a transaction non-compliant, list the policy steps and verify each one.”
False positives dropped 40%.
Review time halved.
The AI stopped “guessing” and started “thinking.”
Pro Tips for Finance Prompts
- Start prompts with “Let’s think step-by-step.”
- Ask it to list assumptions before the final answer.
- Use “Check your work” at the end to catch math slips.
- For long tasks, break it into sub-questions (“First analyze revenue… now analyze costs”).
Multi-Modal Models — Text, Numbers, and Images Together
Your AI Can Now Read Charts, Screenshots, and PDFs — So Stop Copy-Pasting Everything
When I first learned that ChatGPT could read images, I did what any finance nerd would do: I dragged in a screenshot of a messy Excel variance chart and said,
“Explain this to me like I’m the CFO.”
And it actually did. It spotted the revenue trend, called out the margin dip, and even mentioned the outlier region.
Multi-modal AI now includes computer vision capabilities, enabling the analysis of images and visual data alongside text.
That’s when I realized: multi-modal AI isn’t about flashy demos — it’s the end of “Sorry, I can’t open that file.”
What “Multi-Modal” Actually Means
In plain English, it means the AI can understand multiple types of input — not just text.
That includes:
- 📊 Charts and graphs (line, bar, pie — the usual suspects)
- 📷 Screenshots or images (Excel tabs, dashboards, whiteboards)
- 📄 Documents and PDFs (financial reports, invoices, policies)
- 🔢 Tables and structured data (CSV or Excel uploads)
You can now show the AI what you mean instead of describing it.
Metaphor: From “Tell Me” to “Show Me”
Old-school AI was like giving directions over the phone.
You’d say, “In cell B12 there’s a spike — what’s going on there?”
Multi-modal AI is like sharing your screen.
Now it can see the chart, read the labels, and understand the numbers you’re pointing at.
It’s the difference between explaining your dashboard to a stranger and walking them through it live.
Finance Use Cases You Can Try Today
1. Chart Explanations
Upload a screenshot of a Power BI or Excel chart and ask:
“Describe the trend and highlight the top three insights.”
It’ll give you a clean, CFO-ready summary — perfect for slide notes or meeting prep.
2. Report or PDF Summaries
Drag in a multi-page PDF (like a management report or 10-K excerpt) and prompt:
“Summarize the key metrics and risks mentioned in this document.”
Boom: instant executive brief.
3. Spreadsheet Insight Extraction
Upload an image or CSV of your P&L table and ask:
“What stands out about operating margin and SG&A trends?”
The AI will parse the table, calculate deltas, and generate commentary — all without formulas.
4. Invoice and Document Review
Finance ops teams can use it for quick checks:
“Extract vendor name, invoice date, and total amount from this image.”
It’s OCR (optical character recognition) plus reasoning — the AI reads and understands what it’s seeing.
Mini Case Study: The Dashboard Whisperer
A regional FP&A lead used to spend 30 minutes per region writing commentary from Power BI screenshots for weekly exec emails.
Now, she exports the visuals, drops them into ChatGPT with this prompt:
“Summarize each chart in one sentence focusing on revenue drivers, cost trends, and forecast accuracy.”
Result: five crisp insights per region in under five minutes.
Her director thought she’d hired help.
She hadn’t — she’d just gone multi-modal.
Pro Tips for Using Multi-Modal AI
- Crop images tightly. Don’t make it scan your entire desktop screenshot.
- Add context in your prompt.
- “This is a SaaS revenue dashboard — focus on ARR and churn.”
- Combine text + image. Ask questions about the chart, not just “what’s in it.”
- Verify numbers. Always cross-check calculations — AI vision still makes rounding errors.
Why It Matters
Finance work is inherently visual — charts, dashboards, PDFs, screenshots.
Multi-modal AI lets you finally connect the dots between those visuals and the narrative behind them.
You no longer have to retype or export data just to get insights — you can literally show the model what you see.
AI Agents — The Next Level
So far, we’ve taught your AI to read, reason, and even look at charts. Now it’s time for the final evolution: AI Agents — systems that don’t just analyze data, but actually act on it.
AI agents can create AI solutions to solve a wide range of finance challenges, from automating workflows to generating actionable insights.
If basic AI is your analyst, and fine-tuned AI is your senior analyst, then an AI Agent is your finance operations teammate — one that runs workflows, checks status, and follows up on late submissions while you’re still sipping your first coffee.
In Plain English: What’s an AI Agent?
An AI Agent is an AI model connected to tools and data sources — so it can make decisions and take actions automatically.
Instead of just answering questions, it can:
- Pull data from systems (like Excel, ERP, or Power BI).
- Run calculations or scripts.
- Draft commentary or emails.
- Send reminders or updates to teammates.
- Log its results for review.
Think of it as AI with hands — it can press buttons, not just talk about them.
Metaphor: The Analyst Who Doesn’t Need You to Hit “Run”
You know that one analyst who still waits for you to approve every step before refreshing the dashboard?
Now imagine one who doesn’t wait — they fetch the data, run the analysis, write the summary, and drop it in your inbox with citations.
That’s what an AI agent does.
Except it doesn’t complain about working weekends.
How It Works (Simplified)
Most modern AI tools (like ChatGPT, n8n, or Power Automate) now include agent frameworks.
Here’s the basic loop every agent runs:
- Receive a goal.
- “Summarize last month’s financial performance.”
- Plan the steps.
- “Pull data → calculate variances → draft summary → send to CFO.”
- Use tools.
It calls APIs, queries databases, or opens Excel files to get the job done. - Reflect and adjust.
If something breaks (“file not found”), it tries a different approach. - Deliver the output.
A completed report, commentary, or email — often with a link or attachment.
That’s an autonomous loop — the AI thinks and acts.
Finance Example: The Month-End Commentary Agent
Let’s make it real.
Here’s a basic workflow an FP&A team can build with n8n, ChatGPT, and Power BI:
- Trigger: Month-end close file hits your “Actuals” folder.
- Data Pull: The agent uses Power BI or Power Query to combine files and calculate variances.
- Narrative Draft: It sends those variances to ChatGPT to draft commentary by cost center.
- Output: It creates a Word summary and a formatted HTML email for the CFO.
- Follow-up: It checks which cost centers are missing owner comments and sends nudges via Teams.
It doesn’t replace you — it just removes the copy-paste purgatory between Excel, Outlook, and PowerPoint.
Mini Case Study: The Self-Starting FP&A Bot
A mid-size consumer goods company piloted a “month-end agent” inside Microsoft Power Automate and ChatGPT Enterprise.
Before: the FP&A manager spent 6–8 hours per month consolidating commentary.
After:
- Agent pulled data from OneDrive.
- Drafted cost center summaries using a prompt library.
- Sent formatted email to each owner for approval.
Result: 80 % less manual work.
Cycle time cut from 2 days to 3 hours.
Accuracy improved because every number came straight from the source.
The human team still reviewed everything — but they were reviewing insights, not spreadsheets.
Pro Tips for Building Your First Agent
- Start small. Automate one step (like data pull or summary drafting).
- Keep a human in the loop. Always review before it sends anything external.
- Use low-code tools. n8n, Power Automate, and Zapier make this easy — no PhD required.
- Add logging. Make it save every output so you can trace its reasoning (and fix mistakes).
- Test with dummy data first. Trust me on that one.
Why It Matters
AI Agents are where “AI in finance” stops being theory.
They don’t just make suggestions — they run real workflows, enforce consistency, and free you up for strategic work.
You’re not being replaced.
You’re being upgraded — from Spreadsheet Janitor to Finance Ops Architect.
The 7-Day AI Challenge to Turn Knowledge into Results
If you made it this far, congratulations — you now know more about AI than 90% of finance professionals out there.
You understand how models think, how to talk to them, how to feed them data, and even how to make them act. You’re not just reading headlines about “AI in Finance” anymore — you’re ready to do it.
To begin your AI journey, follow the 7-day challenge outlined below and take the first step toward hands-on experience.
But knowing and doing are two very different things. So before you file this guide away and move on to your next fire drill, let’s turn it into something real.
Here’s your 7-Day AI Challenge — one small win each day to turn AI theory into hands-on progress.
Day 1: Pick One Repetitive Task
Find a task that makes you roll your eyes every month — variance summaries, report clean-up, stakeholder emails.
Write it down. That’s your automation target.
Goal: Identify one process that steals your time and sanity.
Day 2: Prompt It Once
Take that task and try prompting ChatGPT (or Copilot) to help with it.
Start simple:
“You are a senior FP&A analyst. Summarize this table in 3 CFO-ready bullet points.”
Don’t worry if it’s clunky — this day is about discovery, not perfection.
Goal: See what AI can already do with zero setup.
Day 3: Give It Context
Now feed it some background: your business type, key metrics, tone.
“You are an analyst at a SaaS company focused on ARR and churn. Write a short summary for leadership.”
Watch how the output suddenly starts sounding like you.
Goal: Get a 50% better answer by adding context.
Day 4: Turn It Into a Template
Take your improved prompt and save it as a reusable template.
Label variables like this:
“Summarize [report name] focusing on [metrics] for [audience].”
You just created your first AI playbook.
Goal: Systematize what worked.
Day 5: Connect Your Data
If you can, use Copilot, ChatGPT Advanced Data Analysis, or Power BI to feed in a live file.
Try something like:
“Using this Excel data, highlight top 3 cost center variances.”
Now the model’s reading your real numbers — not guessing.
Goal: See AI operate inside your actual workflow.
Day 6: Add a Review Step
Test the “trust but verify” loop.
Ask the AI to explain its reasoning:
“Show your steps before giving the final answer.”
Check its math, logic, and language.
You’ll learn where it’s strong — and where human judgment still matters most.
Goal: Build your internal audit trail for AI output.
Day 7: Automate One Step
Now that you have a working prompt and review loop, automate one piece of it.
Use Power Automate, n8n, or Zapier to:
- Trigger your AI when a file updates,
- Generate a summary, and
- Drop it into Teams or your email draft folder.
You’ve just built your first mini-AI agent.
Goal: Save real time — not just curiosity clicks.
Your 7-Day Payoff
By the end of this challenge, you’ll have:
✅ One repetitive finance task AI-assisted or automated.
✅ A reusable prompt template for future reports.
✅ The confidence to scale your AI skills without waiting for IT.
That’s not theory — that’s transformation.
And it starts with one small experiment this week.
