Profit First: Pay the Business Before You Pay the Bills

Every accounting class teaches the same line: sales minus expenses equals profit. Mike Michalowicz looked at that line and saw the problem. Whatever comes last gets eaten. So he moved one word, and a lot of small businesses have been grateful ever since.

The book in brief

The formula in the book is sales minus profit equals expenses. Same three parts, different order. You take the profit off the top the day the money arrives, then you run the business on what's left.

Michalowicz isn't selling a spreadsheet. He's selling a behavior fix. His argument is that expenses grow to fill whatever cash is sitting in the account, the same way a meal grows to fill the plate. So he shrinks the plate.

The method uses separate bank accounts. He names five: income, profit, owner's pay, tax, and operating expenses. Money lands in income, and on a fixed rhythm, he suggests the 10th and the 25th of each month, it gets split by percentage into the others. The operating account is kept lean on purpose. When it's tight, you spend more carefully.

He calls the percentages Target Allocation Percentages, and he tells owners not to jump straight to them. Start small. One percent to profit is fine. The point is the habit, and you raise the number a little each quarter once the habit holds.

The system is more behavioral trick than deep finance, and a seasoned operator may want richer tools. Five accounts can feel clunky. Still, for the owner who is profitable on paper and broke in the bank, it works because it bends to how people behave around money instead of pretending they're calculators.

The Rhynowerks angle

Most experts I talk to who want to teach what they know have the same plan for money: spend whatever it takes to get the first course out, and sort out the rest later. Later is where profit goes to die.

Here's the part of this book that fits someone just starting. You don't need revenue to practice the habit. You need a rule.

Take the tools you'll be tempted by. A course platform like Teachable or Thinkific. An email service like Kit or Mailchimp. A video editor like Descript. A ChatGPT or Claude subscription or two. Each one looks small. Five of them at $20 to $50 a month is a real bill, and it shows up whether or not a single student ever enrolls. That's the "expenses grow to fill the plate" problem, and it starts before the first sale.

So set the plate size first. Decide what the project is allowed to spend each month, write the number down, and make every new tool fight for a spot inside it. If a new tool comes in, an old one goes out. That's the same constraint Michalowicz builds with a small operating account, just applied before there's any income to split.

Then, when the first dollar does come in, take the profit first. Even one percent. It will feel silly. Do it anyway, because the habit is the product here, not the amount.

There's a second lesson in this book for anyone who teaches. Michalowicz didn't win readers by being smarter about accounting. He won them by putting one idea in a form people could follow on a Tuesday afternoon: open the accounts, move the percentages, twice a month. That's what good training does. It turns a principle into a procedure a tired person can repeat.

If your course idea is "understand X," push it one step further. What would someone do on the 10th and the 25th? What's the procedure? The answer to that question is usually the course.

The Bottom Line

Whatever you leave for last gets eaten, so decide what comes first and protect it. Set the spending limit before the tools arrive, and take the profit before the bills do.
