An Expression of Interest (EOI) is a preliminary submission made by a supplier to signal their interest in participating in a potential procurement. Unlike a full bid, an EOI contains essential information—such as qualifications, experience, and capacity—but does not include a detailed proposal. It often serves as the first step in a process where the contracting authority gauges market interest or identifies eligible candidates before issuing a full tender or request for proposal.
EOIs are commonly used in two-stage procurement setups, especially under restricted or preparatory procedures. After evaluating EOIs, the contracting authority may create a shortlist of qualified suppliers who will then be invited to submit formal bids. This approach streamlines the evaluation process and ensures that only capable and interested parties move to the more resource-intensive bidding stage.
In practical terms, submitting an EOI allows suppliers to position themselves early in the procurement process and demonstrate suitability without committing excessive time and resources. For contracting authorities, EOIs enhance efficiency, aid in preliminary market research, and help ensure fair and focused competition going forward.
