What's the difference between a cash-flow forecast and a budget?

A budget plans how much you intend to earn and spend over a period; a cash-flow forecast tracks the timing of money actually moving in and out. The forecast is what reveals the week you might run short, even in a profitable year.

How far ahead should I forecast?

A rolling 12-month view gives strategic visibility, while a detailed 13-week (about 3-month) forecast is the most practical for spotting near-term cash gaps. Many owners keep both — a near-term weekly view and a longer monthly one.

What should I do when my forecast shows a gap?

Act early. Cut or delay non-essential spending, accelerate collections, and arrange funding while your statements still look strong. A line of credit set up before the dip is the cleanest cushion — arranging it the week you run out is the worst time.

How to Build a 12-Month Cash Flow Forecast

A cash-flow forecast is the most useful financial tool a small business can keep, and one of the least used. Done simply, it shows you a shortfall weeks before it becomes an emergency — which is the difference between arranging funding calmly and scrambling for it. Here is how to build one.

Start with cash in, by when it actually lands

List your expected money coming in, week by week or month by month — and date it by when the cash actually arrives, not when you invoice. This is where most forecasts go wrong: a $20,000 invoice sent today might not land for 60 days. Use your real payment history to time it. Be conservative; it is safer to be pleasantly surprised.

Add every dollar going out

Now list money out: payroll, rent, suppliers, loan and lease payments, taxes, software, insurance, and a line for the irregular costs that always show up. Include the seasonal lumps you know are coming. The goal is an honest picture, so do not round the uncomfortable numbers away.

Find the gaps and keep it rolling

Running cash balance = last balance + cash in − cash out, period by period. The weeks where the balance dips low or negative are your funding gaps, and now you can see them coming. Keep the forecast rolling — each month, drop the month that passed and add one at the end, and update actuals against your estimates so it gets sharper over time.

Turn the forecast into a funding plan

A forecast is only useful if you act on it. If you can see a gap in two months, that is the time to act — the best moment to arrange funding is when your statements look strong, not the week you run out of cash. A line of credit set up in advance is the ideal cushion for forecasted dips.

The bottom line: Build a rolling forecast: time cash in by when it lands, list every dollar out, and watch the running balance for gaps. Spotting a shortfall early lets you arrange a line of credit calmly — not scramble for cash when it's already too late.
