Open BusinessOSCommon questions
What's a good DSO?
B2B under 45 days is healthy. Over 60 days = collections problem. Enterprise typically 60-90 days due to procurement cycles. B2C should be near 0 (paid upfront).
How do I reduce DSO?
1) Invoice immediately (not weekly batches). 2) Automated payment reminders. 3) Early-payment discounts (2/10 net 30). 4) Deposits upfront on new customers.
Is DSO the same as average collection period?
Yes — different name for the same thing.
