What is DSO
Also called: days sales outstanding.
Definition
Days sales outstanding: the average number of days between invoicing a client and being paid. Every extra day is cash you have to fund.

In practice
Contract staffing typically sees 35 to 60 day DSO depending on sector. Healthcare systems and large enterprises sit at the slow end; SMEs and tech scale-ups are usually faster.
DSO is partly operational. Late timesheets, wrong PO numbers and missed billing portals add days that no funder will absorb for free.
