Quick answer
Inventory cash flow planning models the cash consumed and released by inventory: when you pay suppliers, how long stock sits before selling, and when sales convert back to cash. For product brands, where inventory is the largest cash use, this planning is what prevents a growing business from running short on cash.
Inventory is the cash story
For a physical-product brand, cash flow is largely an inventory story. You commit cash to a purchase order, wait through manufacturing and shipping lead times, hold the stock, sell it over weeks or months, and only then convert it back to cash. Every step ties up money. Plan it poorly and growth becomes a cash trap.
What inventory cash planning models
- Purchase orders. The cash committed and when it is paid.
- Lead times. Manufacturing and shipping delays before stock arrives.
- Sell-through. How fast inventory converts to sales and cash.
- Reorder timing. The next buy, funded by the last cycle's sales.
Rule of thumb. The faster inventory turns, the less cash growth consumes. Watch weeks of supply and the cash conversion cycle together, not sales alone.
Why it must connect to the forecast
Inventory cash planning is only right if it draws from the demand forecast: how much you will sell drives how much you should buy, which drives cash out. When these are separate spreadsheets, they drift, and the drift shows up as a surprise cash shortfall. Drivepoint links demand, inventory, and cash so a forecast change flows straight into the cash plan.
