How long it takes to actually get paid
Days Sales Outstanding measures the average number of days between a credit sale and collecting payment for it - a rising DSO can signal collection problems even while total sales figures still look strong.
Worked example
For $60,000 in accounts receivable against $730,000 in total credit sales over a 365-day period:
DSO = (60000 / 730000) x 365 = 30.0 days
Compare DSO against the company's own stated payment terms - if standard invoice terms are "net 30" but DSO consistently runs at 45-50 days, that gap points to real collection issues worth investigating before they compound into a larger cash flow problem.
