A request for an expression of interest (abbreviated as RFEI) is a solicitation method used to confirm a supplier’s interest in participating in a competitive bidding process for a contract. For complicated procurement projects, an RFEI provides suppliers with time to evaluate the scope of work for a project, and prepare financial details. An RFEI does not guarantee that a responding supplier will continue to be involved in the solicitation process, and contracts are not awarded directly following an RFEI.
