What is days sales outstanding?
Days sales outstanding is the average number of days it takes to get paid after invoicing. It is calculated as accounts receivable divided by total credit sales for a period, multiplied by the number of days in that period.
DSO measures collection speed, not profitability, which is why a business can be profitable on paper and still unable to pay its own bills. Revenue that has been earned and invoiced but not received cannot be spent.
The number is only meaningful against a baseline. Compare it to your own payment terms first: if you invoice on net 30 and your DSO is 52, the average client is taking three weeks longer than agreed, and the gap — not the absolute figure — is the finding.
A rising DSO is an early warning worth acting on, because the cheapest interventions are the unglamorous ones: invoicing the day work is delivered rather than at month end, stating terms on the invoice itself, and sending a reminder before the due date rather than after. For a single freelancer or small firm, a per-client view matters more than the average — one habitually slow payer can distort the whole figure and hide the fact that everyone else pays on time.
