4 USPS Supplying Practices Process Step 4: Deliver and Receive Requirements

4-1 Ordering

An order is a request made directly to a supplier to deliver specific products or services under certain terms or conditions, some or all of which have been established in advance. A requisition is an internal request for equipment and supply items across commodities that are stocked internally or ordered directly through the MDC, the Express and Priority Mail Supply Center (E&PMSC), Mail Equipment Shops (MES), and elsewhere.

An order or a requisition is submitted via a Postal Service electronic tool. The priority of sources is:

• Excess material.
• Requisitions from Postal Service catalogs.
• Orders against existing contracts or agreements.
• Modifications to existing contracts or agreements.
• New contracts or agreements.
• Credit card purchases.
