How to calculate days payable outstanding
Why days payable outstanding matters for Xero users
DPO is the other side of the working capital equation. A DPO that is too low leaves cash on the table; one that is too high risks late fees, stopped orders, or worse, critical suppliers refusing to trade. Most finance teams track it in a spreadsheet once a quarter and react only when a supplier complains.
Xero users can watch DPO move in real time, by supplier, and catch drift before it becomes a relationship problem.
Understand and act on days payable outstanding with KPI Tree
Query the Xero MCP `list-aged-payables-by-contact` tool alongside the profit and loss cost of goods sold accounts, or use your warehouse tables, and let KPI Tree compute DPO rolling over your chosen window. Break it down by supplier segment so you can tell strategic payment deferral from operational drag.
Assign ownership to your AP lead and set alerts when DPO drifts above or below the agreed supplier terms.
