What is Days Sales Outstanding (DSO)?

DSO measures the average number of days it takes to collect payment after making a sale. It is calculated as (Accounts Receivable / Revenue) x 365.

Days Sales Outstanding is one of the most important metrics for managing accounts receivable and cash flow. A lower DSO means you collect faster, improving your cash position. The calculation is straightforward: (Average Accounts Receivable divided by Total Revenue) multiplied by 365 days. For example, if your average AR is $50,000 and annual revenue is $600,000, your DSO is approximately 30 days. Monitoring DSO trends is more informative than the absolute number. A rising DSO suggests customers are taking longer to pay, which may indicate economic conditions affecting your customers, issues with your invoicing process, or a shift in your customer mix. Improving DSO can be achieved through faster invoicing, clearer payment terms, early payment incentives and consistent follow-up on overdue accounts.
