Businesses do not fail because they are unprofitable on paper. They fail because they run out of cash, which is a different thing and can happen in a record year.
The three statements, in plain terms
- Profit and loss (P&L): what you earned and spent over a period. A movie.
- Balance sheet: what you own and owe on one date. A photograph.
- Cash flow statement: what actually moved in and out of the bank over a period.
The gap between the first and the third is timing. You book revenue when you invoice, but the money arrives when the client pays — and the client is on 60-day terms while your payroll runs every two weeks.
How a profitable month drains the bank
Invoiced this month $60,000 → shows as revenue
Collected this month $18,000 → what the bank saw
Payroll, rent, software $34,000 → left the bank
P&L says: profitable month
Bank says: down $16,000
This is why growing fast is dangerous for service and inventory businesses. Growth means paying for delivery before the money arrives, so the faster you grow, the deeper the hole gets before it fills.
Try it
Open last month’s P&L next to your bank statement. Write down the profit figure and the change in bank balance. Understanding the gap between those two numbers is most of financial literacy.
