Procurement, contracts and agreements (PCA) is Sound Transit's central function through which public solicitations are issued and procurement contracts are awarded for all of the agency's capital, operating and administrative requirements including architectural and engineering services, construction, maintenance, equipment, materials, technology and professional, technical and support services. PCA also manages the internal agency process for the development, negotiation, approval and execution of intergovernmental agreements.

For purchases between $10,000 - $250,000, the agency generally solicits quotes from a minimum of three companies, in which at least one is a small business, based on the firms registered on our solicitation portal and/or market research. The agency also utilizes cooperative purchasing contracts to satisfy requirements where applicable and in the best interests of the agency.
Invoicing and/or Payment Problems
As a Sound Transit vendor, contractor or consultant, there are three ways to get help with any invoicing or payment problems:
- For initial inquiries, contact the Sound Transit Accounts Payable department directly at Accountspayable@Soundtransit.org.
- For any on-going or complex payment inquiries related to your contract(s) with Sound Transit, contact the specific Contract Specialist you worked with during the contracting process.
- In the event an issue or issues require elevation, our payment advocacy group is available to assist. Contact them at STpaymentadvocate@soundtransit.org
Always remember that invoices sent to Sound Transit require a Purchase Order (PO) number or Blanket Release number on the invoice itself in order to be processed efficiently. If you do not have a PO or release # on hand, reach out to your Sound Transit contact directly to acquire one. Invoices that do not contain a PO / Release # will be returned to sender with an explanation as to why it's being returned.
Responsible contractor policy

To that end, Sound Transit utilizes best practices to ensure, consistent with the features of each contract, that it awards contracts to responsible contractors. In 2022, Sound Transit implemented Agency Policy 301 - Responsible Contractor.
