Existing suppliers
As an existing supplier in our legacy Online Vendor Registration system, you'll continue to receive notification of current solicitations until the new system launches in Fall 2020 if your settings are set accordingly. You can click here to view solicitations and click here to customize your account.
New suppliers
As a new supplier with King County we recommend that you register in our current system (Online Vendor Registration) in addition to our new E-Procurement Supplier Portal. This will ensure uninterrupted notifications of solicitations. If you only register in the new system, you can view current solicitations as a guest but will not receive email notifications until the new Supplier Portal goes fully live in Fall 2020.
Registering as a King County supplier is different than certifying as a King County Small Contractor and Supplier (SCS). Maximize your opportunity to do business with King County: make sure to register as a supplier and certify your small firm if eligible. If your firm is already SCS certified, your certification will remain active.
