“We did a million in revenue.” Great line at a barbecue. The problem is that plenty of businesses posting big revenue numbers also quietly went broke that same year. Revenue is the most-quoted, least-useful number in business — because it tells you nothing about whether you actually made money, or whether you can pay your bills next week.
The Math
Revenue is just the top of a long slide. Watch what happens to that “$1 million” on the way down:
From revenue to what you actually keep (illustrative)
So the “million-dollar business” keeps about $35,000 — a 3.5% net margin. That is a completely different story from “we did a million.” A business doing $300k in revenue at a 20% margin keeps nearly twice as much.
And Profit Still Isn’t Cash
Here’s the second trap that catches people: even that $35k of profit is not sitting in the bank. Cash gets locked up in unsold inventory and invoices customers haven’t paid yet. The number of days your money is trapped in that loop is your cash conversion cycle — and a “profitable” business with a long cycle can still run out of cash and die. Profit is an opinion; cash is a fact.
