Two useful numbers, two different questions
Profit measures revenue minus expenses over a period. It is an important measure of performance, but it does not tell you when money arrives or leaves your bank account.
Cash flow tracks the timing of those movements. A business can record a profitable sale today and wait 45 days to collect the invoice. Payroll, rent and suppliers still expect payment in the meantime.
Where the gap comes from
Growth often widens the gap: you may buy inventory, hire ahead of demand or extend terms to customers before receiving the related cash. Loan principal payments and owner distributions also affect cash even though they are not ordinary operating expenses on a profit and loss statement.
- Slow customer collections or large receivables
- Inventory or equipment purchases paid up front
- Seasonal revenue paired with steady monthly costs
- Debt principal, taxes, or owner draws
A practical monthly habit
Review a 13-week cash forecast alongside your monthly profit and loss. Start with the bank balance, list expected receipts by likely payment date, then schedule known outflows. Update it weekly when timing changes.
If the forecast shows a tight week, act early: follow up on receivables, discuss vendor timing, or delay a discretionary purchase. A forecast is not a guarantee; it is an early-warning tool that gives you choices.
