One of the hardest lessons in business is that profit and cash are not the same thing. You can be profitable and still be unable to pay a supplier, because the money is tied up in stock, in unpaid invoices, or in tax you have collected but not yet remitted.
Why profit and cash diverge
Profit is recorded when you make a sale; cash arrives when the customer actually pays. The gap between those two moments is where cash-flow problems live. Fast-growing businesses feel this most acutely — growth consumes cash before it returns it.
You pay staff, suppliers, and tax in cash — not in profit. A cash-flow forecast is what tells you whether the cash will be there.
Building a simple forecast
- List the cash you expect to come in, week by week, based on when customers really pay.
- List the cash going out: payroll, suppliers, rent, loan repayments, and tax remittances.
- Carry the running balance forward so you can see the low points before you reach them.
- Update it weekly — a forecast is only useful while it is current.
Practical levers
Once you can see the cash cycle, you can manage it: invoice promptly, follow up on receivables, negotiate supplier terms, and set aside VAT and PAYE as you collect them rather than finding them at the deadline. We build cash-flow forecasts and management reporting for clients so the low points are visible weeks ahead, not the morning a payment is due.
