Running a Finance Function When You Have No Finance Background

It might be: what is our current ARR? What are our gross margins by product line? What will our cash balance be in 90 days if this deal falls through?

The question isn't a trick. But you can't answer it. And that moment — when you realize you've been running a business with real financial complexity and real financial decisions, and you don't have the data infrastructure to answer the questions that matter — is uncomfortable.

I've worked with hundreds of founders who have had this moment. The ones who respond best are the ones who don't try to pretend the gap doesn't exist. They acknowledge it, find the right help, and fix it.

The ones who don't — who decide they can figure it out on their own, or who hire a bookkeeper and hope that solves the problem — tend to run into the same wall when they finally try to raise capital or sell the business. The financials aren't ready, and the clean-up process takes 18 months that the market won't wait for.

The finance function has three jobs:

1. Recording what happened: This is the accounting role. Transactions are recorded, accounts reconciled, financial statements produced. This is the baseline — without it, you don't know what's actually in the bank, what you owe, or whether you're making money.

2. Reporting what it means: This is the analytical role. Financial statements are analyzed — actuals vs. budget, trends over time, metrics by product line or customer or channel. This turns raw data into information that drives decisions.

3. Modeling what should happen: This is the strategic role. Scenarios are modeled — what happens to cash if we hire 5 more people, what does the P&L look like if we raise prices 10%, what's the ROI on this equipment purchase. This turns information into decisions.

Most businesses at the $3M-$10M stage have the first job handled — or mostly handled. The second and third jobs — reporting and modeling — are where the gap usually lives. And these are the jobs that a CFO does.

The bookkeeper handles the first job. The CFO handles the second and third. If you're making decisions without a model that shows the financial implications, you're doing the CFO's job without a CFO. And you're probably doing it worse than someone who specializes in it.

1. What was your revenue last month vs. this month? (and do you know why the difference exists?)
2. What is your gross margin — total and by product line or service?
3. What is your cash balance right now, today?
4. What will your cash balance be in 90 days, if nothing unusual happens?
5. Who are your top 5 customers by revenue, and what percentage of total revenue is each?
6. What are your three largest expenses as a percentage of revenue?
7. Have your gross margins improved or declined over the past 12 months?
8. What is your average accounts receivable days — and has that number been trending in the right direction?
9. If you had to stop all revenue generation today, how long could you survive without cash coming in?
10. What is your most profitable product or service — and your least profitable?

If you're stumbling on more than 3 of these, you're making decisions — about hiring, pricing, vendor terms, growth — without the data infrastructure to make them well. The CFO closes that gap.

Hiring decisions. The decision to hire a senior employee — a VP of Sales, a Head of Engineering, a COO — costs $200K-$500K in first-year compensation. A CFO builds the model: what does this hire need to generate in additional revenue or cost savings to justify their cost? Does the model show it penciling out — and over what timeframe?

Pricing decisions. The decision to raise or lower prices has a margin impact that compounds over time. A CFO models the elasticity: if you raise prices 10%, how much volume do you need to lose before the price increase is margin-negative? This math is almost never done before the pricing decision is made.

Capital allocation decisions. Should you buy the building or lease it? Should you pay off the debt or invest the cash? Should you acquire this competitor or build the capability internally? These are all CFO-level questions that require a financial model to answer well.

Exit/sale decisions. When should you sell? What does the business need to look like to sell at the multiple you want? What will the acquirer's due diligence find? These are questions most founders don't start asking until they're already in the process — and by then, some of the answers require 18 months of preparation.
