Professional Services Master Contracts

Department of Enterprise Services (DES) Professional Services Master Contracts allow agencies to purchase directly from competitively procured contracts for a variety of professional services. With master contract options for more common scopes of work, or two-tier contracts for unique projects, we prequalify vendors and manage the initial procurement process to provide customers with worry-free tools to meet their needs quickly.

  • Master Contracts are created following Washington procurement laws and policies, then administered by DES Professional Services Team.
  • These contracts are available to state agencies, higher education, political subdivisions and qualified non-profit entities to purchase services directly from the contractors.
  • Purchasers simply complete a Master Contracts Usage Agreement (MCUA) to use the contracts.
  • DES Professional Services Master Contracts provide access to 170 small businesses, 58 certified Women/Minority owned businesses and 12 Veteran owned businesses, helping you meet your diversity goals.
