What's New

Welcome to BuyNet. There is no charge to register or to use our system. If you are a supplier interested in doing business with the County of San Diego, please self-register in BuyNet. If you wish to receive commodity based notifications of new solicitations and changes to solicitations, you must also register for commodities within your BuyNet account profile using UNSPSC commodity codes.

Please email the Department of Purchasing and Contracting if you require further assistance on your vendor or commodity profile.

As a public agency, the County of San Diego must adhere to the California Public Records Act. Therefore, solicitation documents may become public records subject to disclosure at the conclusion of the procurement process. The County intends to publish contracts, which may contain some or all of the successful proposal(s), to its public web site. See the solicitation documents and our FAQs for more information about confidential or proprietary information.
