Important Notice for Vendors:



The contract expresses the complete agreement of the parties and performance shall be governed solely by the specifications and requirements contained therein.

Any change to the contract, whether by modification and/or supplementation, must be accomplished by a formal contract amendment signed and approved by and between the duly authorized representative of the vendor and Clay County prior to the effective date of such modification. The vendor expressly and explicitly understands and agrees that no other method and/or no other document, including correspondence, acts, and oral communications by or from any person shall be used or construed as an amendment or modification to the contract.

A notice of award issued by Clay County does not constitute an authorization for shipment of equipment or supplies or a directive to proceed with services. Before providing equipment, supplies and/or services for Clay County, the vendor must receive a properly authorized purchase order or other form of authorization given to the vendor at the discretion of the Clay County entity.
