About Preferences

In-State/Local Preference

An in-state (local) preference is an advantage given to bidders/proposers in response to a solicitation for products or services, granted based on pre-established criteria. Preference criteria are established by law and can include supplier’s geographic location; residency requirements; or origination of the product or service.

Reciprocal Preference

Reciprocal preference refers to an advantage a state applies in order to match a preference given by another state. A reciprocal preference, or simply reciprocity, defines a bidding situation in which a state gives a preference to its resident bidder against the bid of a non-resident bidder, equal to the preference given by the other state to its own resident bidders.

Tie Bid Preference

Tie bid preferences legally permit a state to preferentially select an in-state or local bidder for a contract if the bid matches that of an out-of-state source.
