Purchasing Reference Guide

This OMES Purchasing Reference Guide is an online resource to assist state staff in making and facilitating procurement-related decisions. The guide is offered pursuant to the responsibility of the State Purchasing Director (OAC 260:115-1-4, OAC 260:115-1-5, 74 O.S. § 85.5) to issue directives, instructions or written communications to state agencies regarding required procurement practices and procedures to ensure compliance with the Central Purchasing Act, procurement rules and other matters relating to state agency acquisitions and procurement.

Although every effort has been made to assure the information in this Guide is correct, the information is not warranted as to accuracy and is not a substitute for, or intended as, legal advice. A particular state agency may be subject to additional procurement requirements specific to the agency; those requirements are outside the scope of this Guide. Agencies should always consult counsel for a tailored legal interpretation with respect to a particular Acquisition.
