Best Practices around Purchase Order Access for Payables team?

Content

Our P2P team often receives missing/ incorrect PO numbers on AP Invoices due to:

1. Work was started by the vendor in a rush, before a PO was issued. They either left the PO field blank or referenced an old PO.

2. Some vendors refuse to put PO numbers on their invoices.

3. General clerical errors by the vendor.

How does your company/ clients work around issues like this without giving the AP team procurement agent access to view purchase orders, as well as the buyer role to access them in the navigator?
