AP Automation stands for Accounts Payable Automation. It automates the capture of bill (vendor invoice) data so you don’t have to key the information into your accounting system manually, automates the approval workflow so you don’t have to chase people down with emails and phone calls to have them approve invoices, and gives you a complete searchable invoice archive in the cloud so you can find a current or paid invoice fast. An advanced version of AP Automation also includes automated PO matching, Requisitions and/or Purchase Order Automation.
