Payables invoice process automation

Our AP department receives invoices from suppliers where they email or print/interoffice them to someone who writes the PeopleSoft supplier ID, account cost center coding, etc. Next, that marked up invoice is sent back to an AP clerk who keys in that invoice with the noted markups.

We are looking for a way to automate this process. Possibly where the supplier emails the invoice to a main email inbox where PeopleSoft can consume the data via OCR...something like what Microsoft Power Automate can do and import that data into the voucher staging tables and voucher build runs. Then the clerk can either update the invoice in quick entry or the voucher page.
