A purchase order is generall​y required for items being acquired for a project, with any exceptions approved by the Project Sponsor or CFO.

A purchase order can be created for goods and services obtained from each vendor.  The purchase order can have multiple line items for the project. Once a purchase order is created it is routed to the Project Manager for checking and approval. 

Approving a purchase order is more than simply approving an order – it is also effectively approval to pay if the vendor delivers according to the order. It should be noted that an approved purchase order is effectively a commitment to pay for the goods and services on behalf of the association and is contractually binding.​
