The 13-Week Cash Forecast: What Founders Should Review Every Week

A practical look at the assumptions, commitments, and decisions that should form part of a forward cash review.

A forecast is a decision tool, not a spreadsheet exercise

A useful 13-week cash forecast helps management see upcoming pressure early enough to act. It should show expected collections, committed payments, payroll, taxes, debt obligations, inventory purchases, and exceptional outflows in a weekly rhythm that management can actually review.

What should be challenged each week

The core question is not whether the sheet balances, but whether the assumptions still hold. Collection timing, purchase commitments, payment discipline, delayed receipts, ad-hoc founder withdrawals, and one-off obligations should all be updated based on current facts rather than hope.

What the forecast should lead to

A forward cash forecast should support real actions: tightening collection follow-up, sequencing vendor payments, deferring non-essential spend, deciding inventory levels, or planning a funding discussion before the pressure becomes immediate. Weekly review discipline matters more than forecast complexity.
