Working capital
The money tied up between paying for operations and collecting from customers.
Accounting working capital is current assets less current liabilities. Operating analysis often narrows the focus to inventories and receivables less operating payables. The cash conversion cycle describes how long cash is tied up between paying suppliers and collecting customer receipts.
Why it matters
A profitable business can consume cash as it grows. It may need to buy stock and pay wages before the related invoice is collected. Conversely, customer prepayments and supplier credit can fund part of an operating cycle.
A worked illustration
Illustrative: goods sit for 40 days, customers pay 30 days after sale, and suppliers are paid after 25 days. The cycle is 45 days. Reducing inventory by 10 days releases cash only if service levels and purchasing economics remain acceptable.
Where the idea can mislead
Negative operating working capital can reflect a strong payment model or overdue bills. Current ratios do not replace a dated cash forecast. Financial institutions require different liquidity analysis.
Questions to ask
- Which event creates a cash outflow, and which creates a cash inflow?
- Does growth lengthen the cycle or require more inventory?
- Are reported receivables actually collectible?

Commercial fisheries convert access to wild fish stocks into landed seafood. Catch availability, fishing rights, vessel economics, handling quality, and management limits determine viable and sustainable output.
- ConstructionProjects and milestones
Construction converts designs, approvals, materials and skilled work into usable assets. Coordination, sequencing and contract risk are as important as the amount of work performed.
- ConsultingExpertise and delivery

- Food processingIngredients and finished food
Food processors turn agricultural commodities into ingredients and finished foods. Safety controls, recipe consistency, processing yield, shelf life, and retailer requirements shape the operating model.
- Grocery retailHousehold baskets
Grocery retailers turn supplier inventories into convenient household baskets. Their economics depend on stock availability, purchasing terms, product mix, labor productivity, and losses from waste or shrink.
- Healthcare providersCare and service capacity
Healthcare providers combine clinical staff, facilities and information to deliver care. Patient needs, payment contracts and safe operating capacity do not always move together.
