Profit First: A Cash Discipline System for Owner-Run Businesses
A Kurums Book Taste review of Profit First for owners whose P&L shows a profit that never seems to reach the bank account.
Why this book fits Kurums
The conventional formula - sales minus expenses equals profit - treats profit as a leftover, and in most small companies the leftover is zero, because expenses expand to consume whatever cash is visible. Michalowicz flips the equation: sales minus profit equals expenses. Take profit first, and force the business to run on what remains.
For the Kurums Accounting audience this is Parkinson's Law applied to cash: a bank-account architecture that does behaviorally what budgets fail to do analytically. Accountants tend to wince at the five-account setup - and then notice their most cash-disciplined clients are the ones running it.
What the book argues
The mechanics are deliberately simple: route all revenue into an income account, then twice a month allocate it by fixed percentages into separate accounts for profit, owner's compensation, taxes, and operating expenses. The percentages - target allocation percentages, set against benchmarks by revenue size - start wherever the business currently stands and ratchet toward health a few points per quarter.
The behavioral core is that entrepreneurs manage from the bank balance, not from financial statements - so the fix is to make the bank balances tell the truth. Small plates: a smaller operating account is the portion-control that stops expense creep. Out of sight: the profit and tax accounts live at a second bank, where they cannot be raided in a weak moment.
The quarterly rhythm makes it stick: every quarter, half the profit account is distributed to owners as a celebration of the discipline, and the rest builds a buffer. The later chapters handle debt destruction (the profit distribution attacks the oldest debt first), when to break the rules, and the diagnosis chapter - an instant assessment that shows most businesses are running double the operating expenses their revenue supports.
Key ideas, translated to your desk
Profit is a habit, not an event
Waiting for a profitable year to start taking profit is backwards. Allocate two percent from the next deposit - the habit matters more than the amount.
Parkinson's Law runs your expenses
Work expands to fill time; spending expands to fill the operating account. Shrink the visible account and watch the business discover which costs were optional.
Separate accounts beat separate line items
A budget line is a suggestion; a separate bank account is a fact. Structure enforces what willpower cannot.
Use it at work
- Open the five accounts this week - income, profit, owner's comp, tax, opex - and route the next deposit through them.
- Run the instant assessment: compare your real allocation percentages to the benchmarks for your revenue band.
- Move the profit and tax accounts to a different bank with no debit card and no online transfer shortcut.
- Set the quarterly ritual: distribute half of profit, review percentages, ratchet one point where the business can bear it.
Read it if
- You own or advise an owner-run business where profit exists on paper and nowhere else.
- Cash surprises - especially tax bills - keep forcing emergency decisions.
- Budgets have failed repeatedly and you are ready to try structure instead of resolve.
You can skip it if
- You run corporate treasury at scale - this is small-business medicine.
- Your accounting instincts cannot tolerate managing from bank balances even as a behavioral layer.
- You already run disciplined cash allocation; the remaining chapters are reinforcement.
