Doing Business with Barnstable County

The Barnstable County Purchasing Division oversees the purchase of goods and services to the various departments of the County Regional Government as well as the collective purchasing of different commodities annually on behalf of the Towns on the Cape and political subdivisions.

Purchasing collectively is strictly on a voluntary basis and not all Towns participate in all purchases. However participation is encouraged as often as possible to take advantage of large purchases through this collective effort.

When the bids are advertised for goods or services that will be offered to the cooperative, a breakdown of the participating Towns and the approximate quantities for each will always be in the bid document. Because of this the bidder will have a very good idea as to the size of the bid and who the participating Towns will be including addresses and locations. As the lead agency, Barnstable County encourages its bidders to take advantage of the buying power of its cooperative.
