What is DSO (Days Sales Outstanding)?

DSO (Days Sales Outstanding) is the average number of days a business takes to collect payment after making a credit sale. Formula: (Accounts Receivable / Annual Credit Sales) x 365. Lower DSO means faster cash flow; higher DSO means working capital is stuck with customers. Indian distributors typically run 30-60 days DSO; reducing to 25-35 days can unlock lakhs to crores in working capital.

DSO (Days Sales Outstanding) in India — Context and Adoption

For Indian distributors — FMCG, pharma, auto parts, hardware, electrical — DSO is the single most important cash-flow metric. Standard industry practice runs 45-60 days DSO because retailer credit is verbal, aging is monthly not weekly, and collection is left to salesmen. Automating with WhatsApp reminders, UPI on every invoice, PTP tracking, and structured escalation typically reduces DSO by 15-25 days within 90 days — unlocking working capital equivalent to 3-8 percent of annual sales.
