Unit Economics

Profit versus Cash

Profit is an opinion produced by accounting rules; cash is the fact in the bank — and the space between the two is where profitable businesses quietly starve.

What decision this helps you make: Where your profit actually went last month — inventory, receivables, debt principal, equipment, draws, taxes — and which statement you're using for which decision.

What this topic is

Profit versus cash is the distinction between accrual accounting's verdict (revenue earned, costs matched) and the bank account's balance — two numbers that measure different things and routinely point in opposite directions.

Why it matters

Businesses don't die of unprofitability directly; they die of running out of cash — sometimes while profitable. Owners who can answer "where did the profit go?" each month catch the divergence early; those who can't discover it as a payroll crisis.

Who should learn it

Every owner — this is the accounting distinction the rest of unit economics stands on.

What you will understand

  • Profit is an accrual opinion; cash is a bank fact — different instruments for different questions
  • The six standard divergences: receivables, inventory, principal, draws, prepaids, taxes
  • The monthly reconciliation: where did the profit go?
  • Which statement to use for survival decisions vs. model-quality decisions

Prerequisites

Common misconception

"If the income statement says we made $10K, there's $10K more in the bank." Almost never. The $10K is an accrual verdict; the bank saw something else entirely — maybe more, usually less — because receivables haven't arrived, inventory absorbed cash before it became an expense, loan principal left without ever touching the income statement, and your own draws did too. Profit and cash agree only in the simplest all-cash, no-inventory, no-debt business — everywhere else, the reconciliation is the skill.
