The detailed Purchase to Pay article stays in the Purchasing section for buyers and AP staff who need the full operating procedure. ## Workflow Overview Purchase to pay is the path from buying decision to paid and reconciled vendor bill. Purchase Orders list with status tabs, search, vendor, total, invoice status, and receiving progress The standard flow: 1. Create the purchase order. 2. Submit for approval if required. 3.
