Instructions to Bidders

The County of Solano, Purchasing Services  partners with The Public Group. The Public Group provides government agencies and their vendors with a comprehensive and easy to use web based eProcurement system, named Public Purchase. For our vendors, this eProcurement system provides automatic notification via a free subscription service and the opportunity to electronically transmit bid responses.  In addition, vendors must register with Public Purchase which will provide access to bid opportunities with other government entities. All of this is provided free of  charge.

To subscribe with Public Purchase and receive electronic notifications regarding upcoming and/or current bidding opportunities with the County of Solano,  visit the free Vendor Registration page at ( and follow the instructions provided. 

Registration is a two-step process. When registration is completed, vendors will receive email notifications of bidding opportunities that match the commodities listed in the vendor profile. Note, that it is critical to list the National Institute of Governmental Purchasing (NIGP) codes related to the services and/or commodities offered by vendors/contractors.

It is the responsibility of contractors and vendors to maintain accurate contact information (email addresses) and keep the vendor profile up to date to ensure receipt of all matching bid opportunities.

Once registered, click on the appropriate bid listing and you will be forwarded to Public Purchase website where you can log in to view and/or respond to solicitations.  Please note: vendors are still required to register with Solano County Purchasing Services as well.  Please complete the vendor application and submit.

To ensure that vendors are aware of all formal bidding opportunities, periodically check our website  and click on the link title Bids/RFPs.
