Your invoices take 45 days to collect. Your suppliers want payment in 30. Your inventory sits for 20 days before it ships. The gap between what you pay out and what flows back in is killing your cash, even though you are profitable on paper.
This is the cash conversion cycle (CCC) — the number of days between spending cash and recovering it — and it is the single largest lever an SME owner controls without touching debt, equity or price. A 30-day improvement releases ₹10–20 lakh for a ₹5 crore turnover business instantly. This playbook shows you how to measure it, where the real bottlenecks sit, and which levers actually move.
Advisory
Cash conversion cycle = (Days inventory outstanding) + (Days sales outstanding) − (Days payable outstanding). For a ₹5 crore turnover manufacturer, if inventory turns every 20 days, receivables take 50 days and you pay suppliers in 25 days, your CCC is 20 + 50 − 25 = 45 days. That means ₹62 lakh (45 ÷ 365 × ₹5 crore) sits locked in the operating cycle at any moment. Most operators know their profit margin but not this number. The first step is to pull 24 months of data: average inventory balance, cost of goods sold, average receivables, cost of sales, average payables, and cost of goods sold. Your accountant can produce this in one afternoon using GST returns (GSTR-1 and GSTR-2) and balance sheets.
Days sales outstanding (DSO) is your average receivable divided by daily credit sales. If receivables are ₹50 lakh and daily sales are ₹14 lakh, DSO = 50 ÷ 14 = 35 days. The lever is not to demand faster payment; it is to restructure terms so cash arrives earlier. Offer 2% discount for payment within 7 days (not 30); offer 1% for 15 days. For a buyer paying ₹10 lakh, the 2% discount costs you ₹20,000 but you recover cash 23 days earlier — that ₹10 lakh can turn again, earning you 15–20% annualised return in your own business. For a 40% gross-margin business, the 2% you concede is recovered in 4 months. Communicate this in your contract and invoice — put the discount deadline in bold, not small print. GST invoice terms are your lever: Section 16(2)(c) of the CGST Act allows input tax credit only when goods are received; payment timing is separate, and you control it.
Days payable outstanding (DPO) is your average payable divided by daily cost of goods sold. If you pay ₹8 lakh per day on average and hold ₹2 lakh of payables, DPO = 2 ÷ 8 = 25 days. Extending this to 40 days recovers ₹12 lakh in cash (15 extra days × ₹8 lakh). The mistake is to simply delay payment; the right move is to renegotiate terms upfront, documented in the purchase order. Tell key suppliers: 'We want to grow with you to ₹10 crore in three years. To invest in stock and capacity, we need 45-day terms from month one, not 30.' Offer a long-term
Frequently asked questions
Cash conversion cycle (CCC) measures days between spending cash and recovering it. It's the largest lever SME owners control without adding debt—a 30-day improvement can release ₹10–20 lakh instantly for a ₹5 crore business.
Use the formula: CCC = (Days inventory outstanding) + (Days sales outstanding) − (Days payable outstanding). Pull 24 months of data from GST returns and balance sheets; your accountant can calculate it in one afternoon.
Yes. Restructure payment terms instead of demanding faster payment—for example, offer a 2% discount for early payment to incentivize faster cash recovery without sacrificing margins.
