The 13-week cash flow forecast, explained

The 13-week cash forecast is the single most useful financial tool in a growing business. It's short enough to be accurate, long enough to be strategic, and weekly enough to drive action.

Start with opening cash. Then layer expected receipts week by week — based on aged receivables and known contracts, not optimism.

Layer outflows next: payroll, rent, suppliers, tax payments and capex commitments. Be honest about timing — most businesses underestimate when bills actually land.

The output is a weekly closing cash position. Sensitised for late receipts, this becomes your operating dashboard.

Review weekly. Refresh assumptions. Track variance. Done well, this single tool removes more anxiety than any other financial output we know.
