Profit First
by Mike Michalowicz · 2017
Mike Michalowicz's premise is simple and slightly heretical: traditional accounting (Revenue − Expenses = Profit) makes profit a leftover, which is why most small businesses run on fumes. Flip the formula — Revenue − Profit = Allowable Expenses — and you guarantee profitability by structurally setting it aside first. The implementation is a multi-account system: separate bank accounts for Operating Expenses, Owner's Pay, Tax, and Profit, with rules for what percentage of revenue goes where based on business size. It's been adopted by tens of thousands of small businesses for good reason. The honest caveat: it's not optimal for fast-growing businesses that should be reinvesting heavily, and Michalowicz's writing veers folksy in a way some readers find tedious.
