A profitable shop can still run short of cash when stock sits too long or customers pay later than suppliers must be paid. The cash conversion cycle makes that timing visible.
Map the three clocks
- Inventory days: how long stock remains before it is sold. Separate fast-moving items from slow stock.
- Receivable days: how long credit customers take to pay after a sale. Count overdue amounts separately.
- Payable days: how long the business has to pay suppliers under agreed terms.
- Estimate cash conversion cycle as inventory days plus receivable days minus payable days. Use actual records, not a guess.
A practical example
Illustration: 25 days in stock + 12 days to collect − 15 days supplier credit = 22 days of cash tied up. If inventory rises to 40 days, the gap becomes 37 days unless another part of the cycle improves.
Before you act
A shorter cycle is useful only if service levels and supplier relationships remain healthy. Do not delay agreed payments merely to improve a ratio.
