Middlesex County vendor contracts consist of the bid/proposal specification, the successful bid/proposal submittal, and the resolution of the Board of Chosen Commissioner. We do not use separate contract documents.

If a bid or proposal requires bid security, it will be described on page one of the document – Notice to Bidders.

If you are a vendor and you have lost a check issued by Middlesex County or need a check reissued for any other reason, you must contact us in writing with the following information: The name of the department that processed the paperwork, check number, and the date paid. If you are unsure or missing any of this information, please include as much information regarding the payment as possible. Remember: The request to reissue a payment must be in writing. The bank requires a mandatory 24 hour wait period after stop payment before reissuing any check. Following the 24 hour wait period, the reissue process may take up to 5 business days.

If a vendor name or address changes please contact the Accounts Payable Division of the Finance Department for a Vendor File Update. Most stop payments on checks are processed because of incorrect addresses. Please verify the remittance address prior to submitting any paperwork to Purchasing or Accounts Payable.
