The County of Stanislaus has recently implemented an online purchasing management system. This system allows vendors to register online, receive automated service and commodity solicitations via email, and eventually allow vendors to submit bids electronically. Most RFQs/RFPs, informal and formal solicitations will be processed through our online system. You may click the "Current BidOpps/Proposals" link above to see a list of all current solicitations, or use the keyword search below to find specific items.

All responses are due on or prior to the time shown on each solicitation. Late responses cannot be accepted. It is the bidder's/proposer's responsibility to ensure that the most complete and current version of the solicitation, including addenda, has been downloaded or otherwise obtained.

Local Vendor Preference: If applicable, subject to the conditions set by Stanislaus County Code 2.24.125, when submissions are evaluated, a five percent (5%) local preference shall be deducted from the total dollar amount bid by local vendors on competitive quotes and bids. The total amount of local preference granted in a single bid shall not exceed $5,000 over a non-local vendor. The award shall be made at full price of the quote or bid.

Thank you for your interest in doing business with the County of Stanislaus.
