Invitation for Bid (IFB)

Usually treated as the same as a request for proposal, but in certain fields the term can indicate a more limited or specifically defined type of solicitation.

Key Points

  • Often used interchangeably with request for proposal (RFP).
  • In some application areas, IFB may mean a narrower, more specific solicitation.
  • Check organizational or industry procurement policies to confirm how IFB is defined.
  • Always state the intended meaning and evaluation approach in the solicitation documents.

Example

A city IT project plans to procure network switches. The agency issues an IFB. In this agency, IFB denotes a specific, formal bidding process with predefined specs, while elsewhere the term might be treated like an RFP. The project manager confirms the local definition to set the correct evaluation criteria and vendor instructions.
