Washington's Electronic Business Solution (WEBS)
IT and Professional Services acquisitions that require formal competition are advertised through Washington State's common vendor registration and notification system. The vendor registration and notification system is called the Washington Electronic and Business Solution (WEBS). WEBS is a central online site where vendors may register to receive bid notifications from all participating government agencies.
Register for WEBS
Vendors can register for free in WEBS.
Minority and women-owned businesses
Minority and women-owned businesses are encouraged to compete for business with the state of Washington. The Office of Minority and Women's Business Enterprise (OMWBE) is responsible for developing programs to improve the contributions of minority and women-owned businesses. For more information about OMWBE, including how to become a certified business, see the OMWBE website at omwbe.wa.gov.
State law encourages agencies to award three percent of all procurement contracts that are exempt from competitive bidding requirements to certified veteran-owned businesses. For more information about becoming a certified veteran-owned business, visit the Veteran Business Registry at the Department of Veteran Affairs website.
