Washington Purchasing Manual (for Historical Reference)

The Washington Purchasing Manual contained both required procedures and guidelines that applied to the purchase of goods and services until December 31, 2012. These procedures and guidelines have changed as a result of Procurement Reform. The manual, its directives and technical corrections, and delegated authorities are provided for historical reference purposes.
