ClockoutWhat is days sales outstanding?
Days sales outstanding (DSO) measures the average number of days it takes to collect payment after an invoice is sent.
Days Sales Outstanding explained
DSO = (accounts receivable / total credit sales) x number of days. For freelancers, a simpler version: average the number of days between invoice-sent and payment-received across recent invoices. Lower DSO means faster collection. Freelancer benchmarks: under 30 is excellent, 30-45 is typical, above 60 is a cash flow risk.
Example
A freelancer sent 10 invoices last quarter. Average days to payment: 34. DSO: 34 days. If automated reminders reduced average collection time to 22 days, cash flow would improve by 12 days per invoice.
