The cash conversion cycle (CCC) measures the number of days between paying for inventory and collecting the cash from selling it. For a small operation, the metric is survival: a business can be profitable on paper and still miss payroll because its cash is sitting on shelves and in unpaid invoices. The Small Business Administration notes that cash-flow problems are a leading reason otherwise viable small firms fail, which is why lenders and counselors push owners to track the cycle before anything else. Orer News publishes information, not financial advice.
In raw terms, the cycle equals days inventory outstanding plus days sales outstanding, minus days payables outstanding. A retailer that holds stock for 45 days, collects from card processors in 2 days, and pays suppliers in 30 days runs a cycle of 17 days. A custom manufacturer holding materials for 60 days, waiting 55 days for customer payment, and paying its own suppliers in 30 days runs 85 days — more than a month of the year's cash locked up per turn.
What is a normal cash conversion cycle?
There is no single healthy number, because the cycle depends on the business model. Grocery stores run negative cycles — they sell perishables for cash before produce invoices come due — while machine shops and builders routinely run 60 to 90 days. The number to watch is your own trend, not an industry trophy. If your cycle lengthened from 45 to 70 days over two quarters, you effectively loaned your customers an extra 25 days of working capital without being asked.
Which lever should you pull first?
Attack receivables before inventory, because collecting faster is usually cheaper than buying less. Practical moves include invoicing the day work completes rather than month-end, requiring deposits on large jobs, offering a small early-payment discount, and running card or ACH options that clear in one to two business days. A firm carrying $80,000 of monthly receivables that trims collection from 50 to 40 days frees roughly $16,000 of standing cash — money that no longer has to be borrowed.
How do payables factor in?
Days payables outstanding is the one term you want to stretch, within the terms your suppliers actually grant. Moving from net-15 to net-30 with a key supplier shortens your cycle by 15 days at zero interest, provided you do not trigger late fees or damage the relationship. Ask for term changes after a stretch of on-time payments, and get any new agreement in writing — an informal arrangement that a supplier's accounts receivable department does not recognize will show up as a dispute on your account.
What does a longer cycle cost you?
The cost of a long cycle is the cost of the capital that bridges it. If you fund the gap with a credit line, every extra day of cycle is another day of interest on the drawn balance; if you fund it by delaying your own maintenance, hiring, or tax deposits, the cost shows up elsewhere. Owners who compute the cycle quarterly, alongside their gross margin, catch the drift early — a slow-paying customer or a bloated reorder point is visible in the ratio long before it is visible in the bank account.
How do you track it without enterprise software?
The three inputs — inventory days, receivable days, payable days — all come from a standard balance sheet and income statement, so a spreadsheet updated quarterly is enough. Average inventory divided by cost of goods sold, times 365, gives inventory days; average accounts receivable divided to revenue gives collection days; average payables divided to COGS gives payable days. What matters is consistency: same formulas, same periods, reviewed on a schedule, ideally before each ordering season and each borrowing-base conversation with your bank.
- Compute CCC = inventory days + receivable days − payable days
- Compare against your own last four quarters, not a generic benchmark
- Invoice immediately and take deposits; that is the cheapest lever
- Renegotiate supplier terms only in writing
Shortening the cycle by even a week can fund growth that would otherwise require a loan, and it costs nothing but attention to the calendar between your suppliers' invoices and your customers' checks.
