Profit First, Explained for Small Business Owners

Most businesses run on a simple formula: Sales − Expenses = Profit. Whatever is left at the end is profit. The trouble is that expenses tend to grow to fill whatever money is available, so there is often very little left.

Profit First, a cash management method introduced by Mike Michalowicz in his book Profit First, flips the formula:

Sales − Profit = Expenses

You take your profit first, then run the business on what remains. It sounds small, but it changes how owners make spending decisions.

The core accounts

Instead of running everything through one checking account, Profit First uses a handful of bank accounts, each with one job:

Account	What it’s for
Income	All revenue is deposited here first. Nothing is paid from it.
Profit	A set percentage of every deposit. This is the business’s reward and reserve.
Owner’s Comp	What you pay yourself for the work you do in the business.
Tax	Money set aside for income tax so tax bills are never a surprise.
Operating Expenses	Everything else: rent, software, payroll, supplies.

Many owners keep the Profit and Tax accounts at a separate bank, so the money is out of sight and harder to dip into.

How money moves

Twice a month, commonly on the 10th and the 25th, you move the balance of the Income account into the other accounts using set percentages. For example, a business might move a small slice to Profit, a share to Owner’s Comp, a share to Tax and the rest to Operating Expenses.

Then you pay bills only from the Operating Expenses account. If that account runs low, that is the signal: the business needs to cut costs or raise revenue, not borrow from profit or taxes.

Allocation percentages: start small

Profit First recommends target percentages that vary by business size and type. You don’t jump straight to the targets. You start by looking at where your money goes today, set allocations close to that, and then shift a point or two each quarter toward the targets. Gradual changes give the business time to adjust its spending.

If your business has significant materials or subcontractor costs, Profit First works from “real revenue”: revenue after those pass-through costs, so the percentages reflect the money you actually control.

Quarterly profit distributions

Each quarter, the Profit account pays out. A common approach is to take part of the balance as a distribution to the owners and leave the rest in the account as a reserve. The point is that profit becomes a regular, visible reward, not something you hope is left at year end.

Talk with your tax professional about how distributions and the Tax account should work for your business structure.

Why it works

• It uses habits, not willpower. Spending from a smaller Operating Expenses balance naturally makes you more careful.
• It makes cash visible. A quick look at your accounts shows whether you’re on track, without waiting for a monthly report.
• Taxes stop being a crisis. Setting money aside with every deposit means it’s there when payments are due.
• Owners get paid. Owner’s Comp and profit distributions are planned rather than taken from whatever is left over.

How bookkeeping fits in

Profit First is a cash management system, not a replacement for bookkeeping. You still need accurate books to know your real revenue, set sensible percentages and review progress each quarter. Clean QuickBooks records and a regular review make the system much easier to run and adjust.

Getting started

1. Open the additional bank accounts.
2. Review the last few months of income and expenses to find your current percentages.
3. Set starting allocations close to today’s reality.
4. Make transfers on the 10th and 25th, and pay bills only from Operating Expenses.
5. Review each quarter and move your percentages toward the targets.

If you’d like help setting up the accounts, choosing starting percentages or keeping the books that support them, a bookkeeper familiar with Profit First can make the first few quarters much smoother.
