Approvals and controls

0 approvals required in this process

  • Check vendor and buyer identity on recordsFiles and requests.
  • Preserve the original source instruction through unknown outcomes.
  • Buyer financial authority stays in the appropriate reviewed action and owning system.

Keep submission and financial approval separate

The supplier’s document belongs to a defined buyer relationship. Its line quantities, net amounts and submitted tax must reconcile before handoff, and supporting files must pass their access and security checks. A received file is not automatically a valid payable.

An identical retry returns the earlier submission result. If the same supplier invoice number arrives with different content, preserve the conflict for review instead of guessing which file is correct. A reviewed replacement links the earlier attempt and buyer correction evidence. It cannot create another payable for an already accepted invoice.

AP acceptance supplies the source invoice identity. Financial review, confirmed due date, open balance and later payment status arrive from the owning system. The supplier should see the actual observed response and its timestamp, including an unresolved outcome after a timeout. Reconcile that original handoff before submitting again.
