Procure to pay process diagram

This is a worked example. Wavelength built the diagram below from the description on this page. Nobody drew it by hand.

What was said

An employee submits a purchase request in Coupa. If the amount is over 10000 dollars, the department head must approve it, otherwise the manager approves it. Procurement sends the purchase order to the supplier. The supplier ships the goods and sends an invoice. Accounts payable matches the invoice to the purchase order and the receipt, then pays the supplier from NetSuite.

The diagram
