Cash conversion cycle (CCC) is the number of days between paying your suppliers and collecting cash from your customers — one of the clearest indicators of whether an SMB has enough working capital to survive a slow quarter.
Many SMB failures are cash flow failures, not profitability failures. A business earning 30% gross margin can still go bankrupt if it pays suppliers 60 days before customers pay it and there is not enough cash on hand to bridge the gap. CCC quantifies that gap in days.
Quick answers
What is the cash conversion cycle? The number of days your cash is locked up between paying for inventory and collecting revenue from selling it. A lower CCC means cash comes back faster. A negative CCC means you collect from customers before you pay suppliers — the business funds itself.
What is a good CCC for a small business? It depends on the vertical. Restaurants and grocery stores typically run 3-15 days because customers pay at the register and inventory turns fast. Specialty retail runs 30-60 days. Manufacturing can exceed 90 days. The target is the lowest CCC achievable without sacrificing supplier relationships or stockout performance.
Can CCC be negative? Yes. If your DPO exceeds your DIO + DSO — meaning you sell goods and collect cash before the supplier invoice is due — your CCC is negative. This is common in businesses with POS collection and net-30 or net-60 supplier terms.
How often should I calculate CCC? Quarterly at minimum. Monthly is better. CCC shifts with seasonality — a retailer's CCC often spikes in Q3 as holiday inventory arrives before holiday revenue does.
The formula
CCC = DIO + DSO − DPO
Where:
- DIO (Days Inventory Outstanding) — how long inventory sits before it sells
