Suppliers are able to view and submit invoices against approved /active Purchase Orders

Purchase Orders can be accessed by:

A. Clicking the Approved POs option on the main dashboard

B. Clicking on the Purchase Order menu option

1. If the Purchase Order is available, you will be able to select the Purchase Order for invoicing.  Select a PO.

  • When is a Purchase Order not available?  the Purchase Order expired, the Purchase Order was cancelled, the Purchase Order is out of funds (out of balance).  


2. Review the Purchase Order information and click convert to invoice. Clicking converting to invoice will flip the Purchase Order to an invoice automatically

3. Enter the invoice number (20 characters max).  Duplicate invoice numbers are not allowed by the system
