Invitation for Bid (IFB)

An Invitation for Bid (IFB) is a procurement document used to solicit sealed competitive bids from sellers when the requirements are precisely defined and the contract will be awarded primarily on the basis of price.

Explanation

An IFB is used when the buyer has complete specifications and wants to select the lowest-priced responsive and responsible bidder. It is commonly used in government procurement and follows a formal sealed-bid process. Sellers submit sealed bids by a specified deadline, and bids are opened publicly at a designated time.

Unlike an RFP, the IFB process typically does not include negotiation. The contract is awarded to the lowest bidder that meets all specified requirements and is deemed responsible (capable of performing). This approach maximizes price competition and transparency.

The IFB process requires that specifications be complete and unambiguous because sellers are bidding on the exact scope of work described. Any ambiguity can lead to disputes after contract award. The resulting contract is typically firm fixed-price, since the clearly defined requirements enable sellers to calculate an exact cost.

Key Points

  • Used for precisely defined requirements with sealed bids
  • Award based primarily on lowest price from a qualified bidder
  • Typically does not include negotiation after bid opening
  • Common in government procurement; results in firm fixed-price contracts

Exam Tip

IFB = sealed bid process, lowest price wins. Used when specs are precise and complete. No negotiation after bids are opened, which distinguishes it from the RFP process.
