Accounts Payable Aging, or A/P Aging, shows outstanding supplier obligations grouped by age.
It helps the business understand what it owes, which payments are coming due, and which balances are becoming old enough to need investigation.
Purchase Order is not Accounts Payable
A Purchase Order says what you intend to buy. It does not automatically mean the supplier has billed you or that Accounting should recognize the same amount as a payable.
A/P comes from the supplier billing and accounting workflow that creates an actual obligation.
This is why Open Purchase Order value and A/P Aging should not be forced to match.
What the report answers
Use A/P Aging to ask:
- Which suppliers are owed money?
- What amount is still outstanding?
- Which obligations are current?
- Which are overdue or old?
- Are supplier payments being applied correctly?
Review before paying an old balance
Before paying simply because a Bill appears old:
- open the supplier Bill
- confirm approval and posting state
- review previous payments and applications
- confirm the amount is still genuinely outstanding
- compare the supplier statement if your process uses one
- resolve duplicates or credits before making another payment
A/P and the General Ledger
The operational supplier obligation should reconcile to the Accounts Payable control account when both use the same posting rules and scope.
If the aging total differs from the ledger, investigate Bills, payments, reversals, and Journal activity rather than editing the report total.
Use it for cash planning
A/P Aging is also useful outside strict accounting review. It tells an owner or finance user which supplier obligations may affect near-term cash.
Combine it with cash position and customer receivables rather than looking at supplier debt in isolation. Last modified on September 7, 2026
