The KPI DSO (Days Sales Outstanding) is one of the most important metrics in accounts receivable management. It shows how long a company waits on average to receive its money — in other words, how quickly customers pay. And this is exactly where KLEVERBILL users achieve measurable results:

👉 On average, KLEVERBILL customers were able to reduce their DSO by an impressive 37.6% within 12 months!

What does DSO actually mean?

DSO stands for “Days Sales Outstanding” and indicates how many days it takes on average for an issued invoice to be paid.

Example:

A DSO of 45 means: On average, your company receives the funds only 45 days after invoicing.

The lower the DSO, the better for cash flow — and the lower the risk of liquidity bottlenecks or payment defaults.

Why does DSO decrease so significantly with KLEVERBILL?

3. Incoming payments are posted instantly
