Profit is an accounting measure of what was earned after expenses; cash flow is what actually moved through the bank account, and a business can be profitable while still running short of cash.
A client is invoiced in December. The revenue appears on the income statement in December. The client pays in February. In January, payroll, rent, and suppliers still need to be covered using cash not yet received, while the income statement shows a profitable December.
This timing gap is the most common source of cash pressure in growing businesses, and it is invisible on the income statement. The owners most exposed are those who make spending, hiring, or distribution decisions based on reported profit without checking actual cash position and receivables aging against upcoming obligations.
