An invitation to tender (ITT) is a formal competitive bidding process in which suppliers provide their bids for a project, typically in an opening environment where bids can be viewed publicly. This competitive bidding method is mostly used in the construction sector for projects that have a well defined set of qualifying criteria for the scope of work involved. The main point of comparison between qualifying bids in an ITT is the price, with the contract being awarded to the lowest bidder. A supplier’s response to an ITT creates a contract “A” arrangement between both parties.
