When Profitable Does Not Mean Fine
Your P&L says one thing. Your bank account says another. Here's why.
There is a specific moment in every founder’s journey that nobody warns you about. It is the moment your accountant tells you the company is profitable, and your bank account disagrees.
I have seen this movie more times than I can count. A founder calls me, confused and a little scared. “We had our best quarter ever. Revenue is up 40%. But I’m not sure we can make payroll next month without a line of credit.” They are not bad at math. They are experiencing one of the most counterintuitive realities in business: profit is an opinion, but cash is a fact.
The Paper Profit Trap
Your P&L says you made $80K last quarter. Great. But that number includes $120K in outstanding invoices that have not been paid yet, minus expenses you already covered out of pocket. The P&L does not care when money moves. It cares when revenue is recognized and expenses are incurred. Those are accounting concepts, not bank balances.
This isn’t a bug. Accrual accounting exists for good reasons. But if you are running a growing company and treating your income statement like a bank statement, you are going to have a bad time.
Growth Eats Cash for Breakfast
Here is what makes this truly maddening: the faster you grow, the worse it gets. Growth requires investment — hiring ahead of revenue, buying inventory before sales close, paying for infrastructure before customers onboard. Every dollar of growth creates a cash gap between when you spend and when you collect.
I worked with a founder a few years ago — let’s call her Sarah — who had $200K in accounts receivable, a 67-day average payment cycle, and $85K in monthly burn. On paper, she was killing it. In practice, she was three slow-paying clients away from a crisis.
The Three Numbers That Actually Matter
Forget your P&L for a minute. If you want to know whether your business is actually fine, look at three things:
Days Sales Outstanding (DSO). How long does it take to collect after you invoice? If this number is going up, your profit is becoming increasingly fictional.
Operating Cash Flow. Not net income. Not EBITDA. Actual cash generated (or consumed) by operations. This is the number that determines whether you can pay people.
Cash Runway. At your current burn rate, how many months of cash do you have? If the answer is less than three, it does not matter what your P&L says.Why Your Monthly P&L Is Lying to You
Okay… “Lying” is strong. Let us say “omitting critical context.” Your monthly P&L does not show you the timing of cash flows. It does not show you that your biggest client seems to have switched to Net 90 terms. It does not show you that your Q2 insurance premium and annual software renewals all hit in the same month.
A monthly P&L is a rearview mirror. Cash flow forecasting is the windshield. You need both, but if you can only look at one, look through the windshield.
This is exactly the kind of thing we talked about with burn rate math a couple of weeks ago — it is all connected. Revenue recognition, burn rate, cash position. You cannot understand any one of them in isolation.
The Fix Is Boring (And That Is Why It Works)
The solution is not complicated. It is a 13-week cash flow forecast. Every Monday, you update it. You look at what is coming in, what is going out, and what the gap looks like. It takes 30 minutes once you have the template set up.
The founders who do this sleep better. Not because the numbers are always good, but because they are never surprised. And in the early stages of a company, surprises are what kill you.
At Runway Health, this is one of the key modules we’re building. Not because it is glamorous — it can literally be a spreadsheet (don’t worry, ours won’t be!) — but because it is the single highest-leverage financial tool a founder can use. It turns “I think we are fine” into “I know exactly where we stand.”
Profitable but not fine. It is more common than you think. What is your DSO right now — do you actually know?
