Contra Costa County has developed the Purchasing Portal website to allow vendors to easily submit and manage their company's information. Purchasing Portal is the tool the County uses to select vendors, issue Purchase Orders, and manage business opportunity programs. Taking the time to register is the first step to doing business with the County.
Purchasing Portal can be reached by clicking on the link below or entering the following URL in your web browser: https://purchasing.cccounty.us. For detailed instructions on registering with Purchasing Portal, click on the Vendor Registration Instructions link below.
