Airwallex gives you the flexibility to control how bills are matched to purchase orders, helping you maintain accurate spending records.
Configuring approvals for Purchase Order Requests
Purchase Order Requests are also known as Purchase Requisitions or Purchase Requests. You can set approval workflows for Purchase Order requests by under Requests, then Settings.
Enabling PO matching for bills
To enable POs in Bills, go to Bills, then Settings, and check the field for "Purchase Order". This allows bills being submitted to be matched to a PO. If your organization requires all bills to be matched, enable the Required Field toggle. This prevents users from submitting bills without specifying a PO.
To set up 2-way and 3-way matching rules and exception handling, refer to this article.
