Owner AI Mastery: Module 5: Finance and Numbers

Understand Your Numbers Without a Finance Degree

Let’s be honest. A lot of owners don’t love their financial statements. They get a P&L from the bookkeeper every month, glance at the bottom line, and file it.

That’s a problem. Because buyers live in those numbers. What your company sells for depends heavily on what those statements say, and on whether a buyer believes them.

AI can be the patient tutor you never had. It can explain what each line means, help you ask better questions, and help you write clear commentary on what changed and why.

But first, the warning.

The Big Rule: AI Makes Mistakes. Always Verify Numbers.

AI can add wrong. It can misread a column. It can confidently invent a number that isn’t in your data. It can mix up months.

So in this module, use AI to understand and explain your numbers, not to be the final word on them.

Check every calculation it gives you, with a calculator, your spreadsheet, or your bookkeeper.
Never send AI-calculated numbers to a lender, buyer, investor, or tax authority without verifying them.
Your CPA is still your CPA. Use AI to walk into that meeting better prepared, not to skip it.

And remember Module 1. Before you paste financial statements into any tool, check that tool’s data settings. You can also remove your company name and round the numbers if you just want to learn the concepts.

Explaining Your P&L

A P&L (profit and loss statement) shows your revenue, your costs, and what’s left over for a period of time.

Here’s a prompt that turns it into a lesson:

I’m a business owner, not an accountant. Below is my P&L for [period], with the company name removed. Explain each major section in plain English. Then tell me the three things a buyer would probably notice first, good or bad. Don’t do any new math. Only use the numbers shown. [paste P&L]

Notice the line “Don’t do any new math.” That reduces the chance it invents numbers. If you want it to calculate something, ask for that separately and check the result.

Some useful terms you might ask AI to explain:

Gross margin: what’s left from revenue after the direct cost of delivering your product or service.
EBITDA: earnings before interest, taxes, depreciation, and amortization. A common way buyers measure a company’s operating profit.
SDE: seller’s discretionary earnings. Roughly, the total financial benefit to one full-time owner. Often used for smaller businesses.
Add-backs: owner expenses or one-time costs a buyer may add back to profit, if you can document them.

Ask AI to explain any term you don’t fully get. Ask again with an example. Ask a third time if you need it. It won’t sigh at you.

Variance Commentary: What Changed and Why

“Variance” just means the difference between two numbers. This month vs. last month. This year vs. last year. Actual vs. budget.

Buyers and lenders love owners who can explain their variances. It shows you know your business.

Here are two columns: [this period] and [last period] for my main P&L lines. For each line that changed by more than [10%], write one plain-English sentence saying what changed. Leave a blank after each line for me to add the reason. Don’t guess at the reasons. [paste numbers]

Then you fill in the “why.” Maybe a big job landed. Maybe material costs jumped. Maybe you hired a new tech. AI helps you organize. You supply the truth.

Once you’ve added the reasons:

Turn these notes into a short monthly summary I could share with my [manager team / lender / advisor]. Clear and factual. [paste]

Cash Flow Questions

Profit and cash are not the same thing. Plenty of profitable businesses run short on cash. AI is a good thinking partner here.

I’m profitable on paper but often tight on cash. Here’s how my business works: [describe how you bill, when customers pay, when you pay suppliers and payroll]. Explain in plain English why this might happen and list 10 questions I should ask my bookkeeper or CPA to find the cause.

Help me build a simple 13-week cash flow forecast in a spreadsheet. Tell me what columns and rows to set up and what formulas to use. I’ll put in the numbers myself.

That second prompt is a good pattern: let AI design the spreadsheet, and you put in and check the numbers.

Pricing Questions

I charge [price] for [service]. My direct costs per job are about [cost]. Help me think through whether my price is too low. What questions should I ask, what should I compare against, and what risks come with raising it? Don’t give me a final number.
