The 13-Week Cash Flow Forecast
The single most important financial tool an SME can build — and how to build it in one week
Who this is for
SMEs with ₹3 crore or more in annual revenue that are managing cash reactively — checking the bank balance rather than forecasting it. Especially relevant for businesses with seasonal revenue, long payment cycles, or rapid growth.
What it costs you to ignore it
The diagnosis behind it
This playbook is triggered by a Red or Critical finding on:
Vital 2 — Working Capital & CashThe Protocol
List every cash inflow expected in the next 13 weeks: customer receipts (by invoice, not by revenue recognition), loan drawdowns, asset sales, refunds
List every cash outflow committed in the next 13 weeks: salaries, vendor payments, loan EMIs, GST/TDS, rent, capex commitments — by due date, not by accrual
Calculate the net cash position at the end of each week. Identify any week where the closing balance goes below your minimum operating buffer (typically 4 weeks of fixed costs).
For each stress week, identify the lever: accelerate a collection, defer a payment, draw on an overdraft, or delay a discretionary outflow. Document the action and the owner.
Update the forecast every Monday morning. Takes 30 minutes once the template is built. Replace actuals for the week just closed; roll the forecast forward by one week.
What you can do yourself vs what needs help
This is entirely buildable internally. The CFO or a senior finance manager can complete the initial build in one week. If your finance team does not have the bandwidth or the template discipline, an advisor can build the first version and train the team to maintain it.
