How it’s calculated
DSO = Accounts receivable ÷ Revenue × 365
Last 12 months, 365-day year, one currency.
A lower DSO means faster collections and stronger working capital. A higher DSO can signal customer payment delays or tightening liquidity.
What it tells you
- How many days, on average, sales sit unpaid.
- Where collections are improving, or slipping.
