Profit First by Mike Michalowicz is a cash management book for owners of small and growing companies, first self-published in 2014 and reissued by Portfolio in a revised and expanded edition in 2017. Its idea fits on a sticky note: stop treating profit as whatever is left at the end of the year and set it aside the moment money comes in.
What is Profit First about?
Accounting teaches the formula sales minus expenses equals profit. Michalowicz argues that this order sets owners up to fail, because people spend what they see in the bank. If the account holds 20,000, the business finds a way to use 20,000. So he reverses the formula: sales minus profit equals expenses. You pay the profit share first, and the company learns to live on what remains, the same way a household learns to live on a salary after pension contributions.
The method runs on a handful of bank accounts. All income lands in one account. On a fixed rhythm, twice a month, you split that money into accounts for profit, owner pay, tax and operating costs, using target percentages that depend on the size of your company. Then you move the profit and tax accounts to a second bank, so they are out of sight and harder to raid. Each quarter the profit account pays the owner a small distribution as a reward, and the rest stays as a reserve.
The book mixes the mechanics with stories from business owners who used the system to climb out of debt. Michalowicz writes in a loose, joking style with plenty of personal confession, which makes a dry subject easy to read. The 2017 edition adds more detail on percentages, debt payoff and how the system works alongside an accountant.
What are the main lessons for founders?
- Profit is a habit, decided in advance. Waiting for profit to appear at year end rarely works. Fixing a percentage now forces you to question every cost.
- Use your bias for good. You will spend what is visible, so make the right money invisible. Moving tax and profit to another bank is a small trick with a big effect.
- Start small, then raise the bar. Begin with 1 percent profit if that is all the company can handle. Add a point or two each quarter as you cut waste.
- Give your money a schedule. Allocating on the 10th and 25th replaces daily anxiety with a calm routine, and it shows trends in cash before they turn into a crisis.
- Pay yourself on purpose. Owner pay gets its own line, so you stop living on whatever happens to be left after suppliers.
Who should read Profit First?
Read it if you run a service business, an agency, an online shop or a consulting practice that brings in steady money but leaves you short every month. It suits bootstrapped founders, freelancers turning into small companies and family businesses. The system needs no software and no finance degree.
Venture-backed startups burning investor money on purpose can skip most of it. If your plan is to lose money for several years to win a market, the book’s focus on quarterly profit will clash with your board’s expectations.
How do you put Profit First to work this week?
- Open the accounts: one for income, one each for profit, owner pay, tax and operating costs. Put the profit and tax accounts at a second bank.
- Look at the last 12 months of income and costs, then pick modest starting percentages. Write them on a card next to your desk.
- Set two calendar slots per month for allocation, and do the first one this Friday, even if the amounts are tiny.
If you are still building the plan behind the numbers, the free Business Plan Generator on Fe/male Switch helps you lay out costs, prices and income targets in one place.
Where does Profit First fall short?
The system treats every business like a small service firm with steady cash coming in. Companies with long sales cycles, inventory, hardware or big upfront costs have to bend the percentages a lot, and the book gives limited help with that. It also says little about funding, investors or growth that needs heavy spending before it pays off. Pair it with Venture Deals if you plan to raise money, and with The E-Myth Revisited if your real problem is that the business depends on you for everything.
