Save and rename vendor invoices to central folder

Vendor invoices arrive as unstandardized attachments, slowing reconciliation and payment readiness. They get renamed and stored in the accounting folder for fast retrieval before the next payment run.

Overview

Invoices hidden in inbox threads slow billing and risk missed payments; this flow standardizes filenames and deposits attachments into the shared accounting folder. Billing staff get immediate, correctly named files for reconciliation, enabling processing before the next payment run.
