Build from cash movements

Start with opening bank balances and expected weekly receipts and payments. Use customer-level collection assumptions for significant receivables and include payroll, taxes, debt service, imports and major capital commitments.

Reconcile the first weeks closely to known bank activity so the forecast remains operational rather than theoretical.

Use scenarios

Create a base case and targeted downside assumptions for slower collections, weaker sales, cost changes or major unexpected payments. Scenarios help management decide which actions should be prepared in advance.

Turn the forecast into a routine

Update actual cash weekly, roll the horizon forward and investigate forecast errors. Over time, this improves assumptions and creates accountability around collections and discretionary spending.
