DSO is trade receivables divided by credit sales for a period, multiplied by the number of days in that period. A DSO of 60 on 30-day terms means customers are paying, on average, a month late. Lowering DSO releases cash that is otherwise lent free of interest to buyers.
How DSO works in India
Take trade receivables from the balance sheet or ledger at period end, and credit sales from the sales register for the same period. Exclude cash and advance sales. Many Indian SMEs compute DSO quarterly with 90 days, or monthly with 30 days. A rolling three-month DSO smooths seasonal spikes, such as festive-season dispatches.
DSO is an average, so it hides concentration. One large buyer 200 days late can push DSO up even when every other buyer pays on time. Always read DSO alongside the ageing report.
Why it matters for getting paid
Every day of DSO is working capital you finance, usually through an overdraft or cash credit limit. A rising DSO is often the first sign that a buyer is under stress, long before a cheque bounces. Unpaid invoices also carry GST that you have already deposited, and the limitation period keeps running. Tracking DSO monthly tells you when reminders are no longer enough and a legal notice is needed.
How FundRaksha uses it
FundRaksha Collect brings DSO down at the source with automated payment reminders and UPI Autopay or NACH mandates, for a 1% fee on what is collected. Invoices that are already well past due move to FundRaksha Legal, where a dedicated advocate sends a notice within 24 hours and charges 30% only on recovery. A free consultation reviews your ledger and DSO.
Worked example (hypothetical)
A Rajkot pump manufacturer has trade receivables of ₹1,20,00,000 at the end of a quarter in which credit sales were ₹1,80,00,000. DSO = (1,20,00,000 ÷ 1,80,00,000) × 90 = 60 days. Its terms are 30 days, so buyers are paying a month late on average. Average daily credit sales are ₹2,00,000 (₹1,80,00,000 ÷ 90). If reminders and mandates bring DSO down to 45 days, receivables fall to about ₹90,00,000, releasing ₹30,00,000 of cash (15 days × ₹2,00,000) without a single new sale.
