A materials purchase order is used in the construction field specifically for the purchase of building materials and supplies. The form identifies the buyer and seller, provides the shipping address, and lists items being ordered with their prices and total cost. It’s common for a separate purchase order to be made for each category of supplies required to complete a job.

A materials PO is sent to a supplier or vendor by a general contractor (GC), project manager, or department head to order building supplies such as lumber, drywall, concrete, or rebar.
When the materials are delivered, the vendor’s invoice can be compared with the PO before paying to ensure the delivery matches the order.
