THE FINANCIAL MECHANICS

The funding gap starts before the sale

The funding gap starts before the salePay for stockWeek −6Make the saleWeek 0Receive cashWeek +2Cash advanced for approximately 8 weeks
Hypothetical timing example, not a company dataset. Inventory paid six weeks before sale; proceeds available two weeks after. Fees, returns and overlapping purchases are excluded.

01Business Reality

A purchasing decision can improve availability today and leave the business holding months of excess stock tomorrow. Fast growth encourages larger commitments, even when the strongest sales period is temporary.

Build a hypothetical seasonal assortment story. Separate accounting inventory value from the cash realistically recoverable through future sales.

02Financial Mechanics

Link demand, lead time, order quantity and safety stock to inventory investment. Calculate inventory days using consistent cost-based measures; averages can conceal obsolete items and critical stockouts.

Model holding costs, markdowns, returns and recoverable proceeds. For a liquidation decision, compare future net cash from selling now with expected future net cash from holding; historical purchase cost remains relevant to accounting results but is not a new cash outflow.

03Decision Trade-offs

More stock protects service levels but increases funding needs and obsolescence risk. Lower stock can improve cash while causing lost sales, expedited freight or supplier disruption.

Compare smaller batches, supplier flexibility, assortment reduction and targeted clearance. Address the tension between purchase-price savings and total capital exposure.

04CFO Perspective

Challenge purchase commitments before cash leaves, not only provisions after demand disappoints. Review outstanding orders alongside stock on hand and realistic demand.

Make responsibility shared across finance, sales and supply chain. Forecast error and incentives matter: a revenue-only target can reward inventory decisions that weaken cash returns.

05Practical Framework

Segment inventory by demand stability, age, lead time, contribution and strategic importance. Track coverage, sell-through, stockout exposure and open commitments at SKU level.

Create separate replenishment and clearance rules. Tie purchase approvals to cash forecasts, define exception owners and review the cash released or margin sacrificed by each action.

All numerical examples are hypothetical, not client results. Definitions, assumptions and business context affect the conclusion.
