A 13-week forecast is a rolling weekly view of expected cash in and cash out. It is most useful as a decision tool, not a prediction of perfect accuracy.
Start with beginning cash
Use reconciled or otherwise verified available cash as the starting point. Separate restricted or unavailable funds when they cannot actually be used for ordinary operations.
Map expected customer collections
Forecast cash receipts based on open invoices, customer payment patterns, known billing dates, and realistic collection assumptions. Do not treat every invoice as if it will be paid exactly on its due date.
Schedule payroll and vendor outflows
Place payroll, taxes, rent, debt service, recurring charges, approved bills, major purchases, and known one-time obligations into the week cash is expected to leave. This exposes timing pressure that a monthly profit report cannot show.
Update the forecast every week
Roll actual cash activity into the model, revise collection assumptions, add new obligations, and extend the horizon by another week. Comparing forecast with actual results also reveals where assumptions are consistently weak.
Use the forecast to make decisions early
If a future week shows pressure, management has time to accelerate collections, reschedule discretionary spending, discuss vendor timing, adjust purchasing, or evaluate financing before the shortage becomes immediate.
A useful forecast makes assumptions visible and improves as actual collections and payments replace estimates.
