Cash flow isn't profit — and that matters more than you think

Most small business owners can tell you their revenue. Fewer can tell you their cash flow. And that gap is where businesses die.

Revenue is what you earn. Cash flow is what you actually have in the bank — after payroll, after rent, after that vendor invoice you forgot about. A business can be "profitable" on paper and still run out of cash. It happens all the time.

Here's the thing: cash flow problems don't announce themselves. They creep. You cover a slow month with savings. Then another. Then you're floating payroll on a credit card and wondering how you got here.

The fix isn't complicated, but it does require discipline:

Track it weekly, not monthly. Monthly P&L statements are useful, but they're rearview mirrors. A weekly cash flow snapshot — what came in, what went out, what's committed for next week — gives you time to react.

Know your runway. At your current burn rate, how many months can you operate without new revenue? If the answer makes you uncomfortable, that's information you need.

Separate operating cash from everything else. Growth capital, tax reserves, emergency funds — these aren't operating cash. Treating them like they are is how "profitable" businesses end up insolvent.

Build a 13-week forecast. It sounds formal, but it's just a spreadsheet. Week by week, what do you expect to come in and go out? Update it every Friday. After a month, you'll wonder how you ever ran without it.

The business owners who survive downturns aren't always the ones with the most revenue. They're the ones who see the cash picture clearly — and act before the picture gets ugly.
