Invitation to Bid Law and Legal Definition

Invitation to bid is an oral or written letter sent out to prospective suppliers to submit a bid on materials or services. It is only a solicitation, and does not qualify as an offer because the party making it does not wish to enter into a binding agreement without further negotiations. An invitation to bid explains the description of the building, its location, the terms and conditions of bid, and a date and time of the bid opening which is the deadline for bid acceptance.
