Profit vs Cash Flow
Profit measures performance using accrual rules; cash flow measures how cash actually moved in and out over a period.
Why It Matters
If you treat profit as spendable cash, you will mis-run a business. Accrual accounting is useful precisely because it is not identical to your bank balance—but you still live in the real world where payroll clears in cash.
Two lenses
Profit
- Income statement view
- Includes earned revenue and incurred expenses
- Smooths timing with rules
Cash flow
- Bank and liquidity view
- Captures collections, payments, capex
- Shows survival and optionality
What This Means
Working capital is the usual bridge: receivables, inventory, and payables connect recognized performance to when cash lands. Prepayments show up as deferred revenue on the other side of the timing story.
How Profit and Cash Diverge
Under revenue recognition, you might book revenue when you ship. If the customer pays 60 days later, profit can look fine while cash lags.
You can also collect cash early and still defer revenue—cash rises while profit does not yet—until delivery catches up.
Neither pattern is automatically “good” or “bad.” The skill is explaining the gap with a story you can verify on the financial statements.
