See the recorded product workflowDecisions to make before billing
A review of paid invoice cycles starts with a precise question: how many calendar days elapsed from issue to confirmed full payment for a defined group? That question differs from how overdue today's balances are, and from the portfolio relationship between receivables and sales used for DSO.
Use a consistent sample rule and amount basis. Record every included invoice and explain exclusions, especially unresolved invoices and cases closed through non-cash adjustments. A small completed sample may help identify cases to investigate, but its average cannot describe the entire outstanding portfolio.
The fictional three-invoice example has durations of 10, 20 and 30 days. The arithmetic mean and median are both 20; a larger 30-day invoice raises the amount-weighted mean to 24. Neither figure proves why payment took longer or that automation changed the outcome.

Outcome
Use this page to move from general research into a calmer, more repeatable invoicing process.
Work through the billing decision
Choose the sample before computing
Write the issue-date range, eligible service group, currency and completion rule. Preserve included and excluded IDs so another reviewer can reproduce the selection.
Verify dates and compare measures
Use confirmed full-payment dates, not first installments or promises. Calculate calendar-day durations, then compare mean, median and amount-weighted results alongside count and totals.
Investigate actual cases
Review billing contacts, agreed terms, disputes and delivery evidence for the selected cases. Treat causal explanations as questions until evidence supports them; review unpaid aging separately.

Avoid this
Measuring only successful cases without a label
Outstanding invoices may be the slowest cases. Make the completed-sample boundary prominent and keep a separate open-balance review.
Avoid this
Calling the sample DSO
Xero describes DSO using portfolio receivables and sales inputs. Three completed invoice durations use a different basis.

Questions people usually have before changing the workflow.
Should payment terms be subtracted?
Not for issue-to-full-payment duration. If reviewing lateness, define and calculate that separate measure explicitly.
Why compare median and weighted mean?
They answer different sample questions: the middle duration versus time weighted by the entered invoice amounts. Neither is automatically the best performance target.
Can I infer improvement from one sample?
Only with a fair comparable definition and sufficient evidence. A different client mix or omitted unresolved invoices can change the result.
