E-Procurement supplier roles overview
There are four supplier roles within the new system. Each company contact may have as many roles assigned to them as is appropriate. The system will automatically add two roles to each contact that has a User Account: Administrator and Bidder. The definitions and permissions of each role are highlighted below.
While most of the columns in the matrix are self-explanatory, one distinguishing difference between the roles is the Qualification Questionnaire. A Qualification Questionnaire is a function whereby an organization is requested to respond to an ad hoc questionnaire produced by King County in order to learn more about the supplier community and/or pre-qualify the organization for a solicitation.

Will I receive solicitation notifications for business opportunities with King County?
If you're a registered supplier in King County's updated E-Procurement Supplier Portal you'll receive email notification of County solicitations that match the NAICS codes you selected in the registration process. Current County opportunities can also be viewed here. King County also advertises social media platforms LinkedIn and Twitter, and printed in media outlets like the Seattle Times.
Will the launch of the E-Procurement Supplier Portal impact my current contract with King County?
No changes will be made to existing contracts with the implementation of the King County E-Procurement system on October 26. You will continue to work with the same King County contact and receive any Purchase Orders via the same path (None/Fax/Email) as originally specified.
Will the launch of E-Procurement Supplier Portal impact my current payments?
Changes to the new procurement system will not make any changes to your current payment method or where you submit invoices. The new registration process will give you more direct control of where your payments are delivered once it goes live October 26. If you need to make updates to your payment preferences before the new system goes live, please reach out to your regular point of contact at King County.

Registering as a King County supplier is different from 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 but your firm must register in the new supplier portal.
Supplier registration will:
- Allow your company to receive King County solicitation notifications
- Allow your company to respond to King County solicitations and qualification questionnaires electronically
- Allow your company to enroll on King County's Rosters (unadvertised solicitations)
- Enhance your company's collaboration and messaging capabilities with County employees
- Grant access to your company's King County activity dashboard
The Small Contractor and Supplier (SCS) certification will:
- Improve the effectiveness of certified small businesses to compete for King County contracts as contractors, consultants, and suppliers
- Qualify your company for various programs in solicitations to benefiting certified small businesses
The King County Small Contractor and Supplier (SCS) certification will continue to be managed by the Business Development and Contract Compliance team and executed through the Diversity Compliance Management System (DCMS). If eligible, start your application to get SCS certified.
State and Federal Certifications will continue to be managed by Washington State Office of Minority and Women's Business Enterprises.
How do I apply for Rosters in the E-Procurement Supplier Portal?
Signing up for a roster just got much easier. Instead of completing a full roster application in addition to registering as a supplier, now the two processes are integrated into the new registration process. Simply opt-in to the various rosters that apply to your organization in the final step of the supplier registration in the new system.
Do suppliers awarded community grants by King County need to register their company in the E-Procurement Supplier Portal?
It's recommended all suppliers register within the supplier portal to increase their awareness of bidding opportunities beyond community grants awarded by the County.
How do I know which NAICS industry codes to enter?
Go to the NAICS website for a full listing of NAICS codes. Please register for all applicable codes to ensure the highest probability of receiving solicitations. If you need additional assistance, reference the NAICS Quick Reference Guide.
Does the E-Procurement Supplier Portal support electronic invoicing?
Electronic invoicing is not a part of the current implementation but it is something King County will be pursuing in the future.
