Profit is not the same as cash, and cash is what keeps the lights on. This guide covers practical ways to see, forecast and protect your cash flow.

Profit is what is left after costs; cash flow is about timing, when money actually arrives and leaves. You can be profitable on paper yet short of cash if customers pay late or you buy stock upfront. Watching cash, not just profit, keeps you solvent.
List expected money in (by when you realistically expect payment) and money out (bills, wages, tax) over the coming weeks. The running balance shows any dips before they arrive, giving you time to act.
Invoice promptly, make paying easy, take deposits for big jobs, and follow up overdue invoices systematically. Getting paid a week sooner across the board can transform your position.
Spread large costs where sensible, negotiate terms with suppliers, and set aside tax as you earn so it never blindsides you. A small buffer smooths the inevitable bumps.
Usually timing: customers have not paid yet, or you have paid for stock, tax or assets upfront. A cash forecast makes the mismatch visible.
Rolling 12 weeks is a practical horizon for most small businesses, updated regularly.
