STA Purchasing

Vendor Self Service


The STA Purchasing Team is dedicated to providing efficient and responsive service while upholding the highest ethical and professional standards. It is our goal to build valued partnerships with our vendors, contractors, and suppliers and to find economic solutions that meet the needs of our community.


STA utilizes several methods for procuring goods and services including obtaining price quotes, Request for Qualifications (RFQ), Request for Proposals (RFP), informal and formal invitation for bids (IFB), and state and intergovernmental contracts.

Purchasing methods are selected based on the type and dollar amount of the purchase and procedures are guided by federal, state, and local requirements and STA policies. All formal solicitations are advertised on our website under Bidding Opportunities.

Vendor Responsibilities

Vendors and contractors wishing to do business with STA should obtain a Unified Business Identifier (UBI) number prior to bidding and have the ability to obtain applicable business licenses prior to beginning work.

More information can be found at the Washington State Department of Revenue website Suppliers that are only providing a product are not required to obtain a UBI number. Federal or State prevailing wage rates apply to public works projects and bidders are responsible for verifying and using up to date prevailing wage rates.
