You can only change the vendor on a previously entered invoice if the following conditions are true:

• The invoice is fully open and none of its distributions are fully or partially paid.
  • Note: You cannot change the vendor on a paid invoice unless you void the payment paid to the incorrect vendor. Refer to article 26501 DocLink: An Accounts Payable invoice was entered to the wrong vendor and has been paid
• The new vendor has the same vendor type (Setup, Vendors) as the current vendor assigned to the invoice.
  • Note: You cannot change the vendor if the incorrect vendor is of another vendor type because invoice distribution information differs by vendor type.
• The invoice has not been distributed to a Job Cost commitment/purchase order/subcontract.
  • Note: You cannot change the vendor on an invoice assigned to a Job Cost commitment/purchase order/subcontract because they are vendor specific.

Note: If the vendor on the invoice is for a different vendor type or the invoice is distributed to a Job Cost commitment/purchase order/subcontract, then the invoice will need to be deleted in Change Invoices and re-entered under the correct vendor. Refer to article 17498 DocLink: How do I delete an invoice in Accounts Payable?

If all of the above conditions are true, change the vendor assigned to the invoice as follows:

1. From the Tasks menu, select Change Invoices.
2. Enter the vendor ID and press Enter.
3. Enter the invoice ID and press Enter.
4. Click Change vendor.
   • If the Change vendor button is disabled, then the invoice does not meet the conditions listed above to use this feature.
5. Enter the new vendor ID and then click OK.
6. Click Accept invoice and then click Finish.
7. Click Start to print the journal to a file or printer.
