New eProcurement Portal Coming Soon!
On December 16, 2025, the City will transition to a new eProcurement solution (OpenGov) for publishing solicitations, and receiving vendor responses. Register your account early to begin receiving email notifications for the City’s Bid/RFP opportunities. Registration is 100% free for vendors!
The City of Mercer Island, WA has partnered with OpenGov and is excited to announce our transition from a paper-based bid solicitation process to a fully automated, web-based electronic bidding and vendor management system. Below are the bids and proposals currently being solicited and the corresponding closing dates for each. Our new eProcurement Portal will allow interested parties to do the following:
- Register to bid and receive notifications of future opportunities in the eProcurement Portal by selecting Subscribe to create an account.
- Follow updates to existing solicitations by finding the solicitation and clicking the Follow button. This will allow all interested parties to receive amendments and addenda automatically.
- Submit questions and receive answers for open solicitations.
- Guide vendors through the process of responding electronically to RFPs, bids, etc. to ensure submissions have been accurately completed.
- Ultimately, be your one location for all bid opportunities issued by the City.
