How to reduce your debtors days outstanding

Debtors days outstanding (DDO) — the average number of days it takes your clients to pay you — is one of the most direct levers on your working capital. Reducing DDO by 10 days on ₹5Cr of annual revenue frees up approximately ₹14L of working capital. That's capital you can use to grow without borrowing.

The starting point is measurement. Calculate your current DDO: (accounts receivable / annual revenue) × 365. If your revenue is ₹5Cr and your AR is ₹80L, your DDO is 58 days. Now understand what it should be — your payment terms say 30 days, so your DDO target is 30–35 days. The gap between current and target is your improvement opportunity.

Invoice quality is the most underrated factor. Late payments are often caused by invoice errors — wrong GST number, missing PO reference, wrong billing address, mismatch with agreed rates. Every error adds 15–30 days to collection. Audit your last 20 invoices for errors, fix the recurring ones, and implement a pre-invoice checklist.

Invoice promptly. Many Indian businesses invoice weekly or monthly — meaning the payment clock doesn't start until the invoice is sent. Invoice on the day of delivery or service completion. If you're invoicing at month-end for services delivered throughout the month, you're adding 15 days to your average collection cycle for free.

Follow up systematically. Before the due date: a reminder 5 days before payment is due (many AP teams will process this rather than track their own deadlines). On the due date: a payment confirmation request. 5 days after: a follow-up. 15 days after: escalation to a senior contact. This systematic approach, applied consistently, improves collection without damaging relationships.

Incentivise early payment. A 1–2% early payment discount for settlement within 10 days has a cost — but if your cost of capital is 15–20%, a 1% discount for 20-day early payment is a better deal for you than the working capital cost of waiting.
