IFB
Invitation for Bid
Sealed bidding — the lowest responsive, responsible bid wins. Pure price game.
An Invitation for Bid (IFB) uses sealed bidding. Bids are opened publicly and the lowest responsive, responsible bid wins. "Responsive" means you followed every instruction; "responsible" means you can actually perform.
IFBs are common in construction and state/local work. There is no beauty contest — it is a pure price game with pass/fail compliance, which makes it a realistic entry point for hungry new firms.
