What to include in a Purchase Order

A complete purchase order helps ensure your parts are processed to your expectations.  An incomplete PO can also cause delays in processing.  Please review the following items to ensure the proper process is communicated to our process design and order entry teams.  Contact us with any questions if you would like clarification on what needs included in your order.  If a PO does not include certain information, we will assign our standard processes and procedures.  In some cases (hardness ranges, material, etc.) a job can not progress until the information is received from the customer.
