We understand that procurement can be confusing. Organisations often use different terms to describe the same thing. With that in mind, we designed this glossary to make buying with us and navigating our website easier. It is not designed to be an extensive list of all procurement terms.


Expression of Interest

An Expression of Interest (EOI) is a set of high level requirements outlined by the buyer and sent to potential suppliers. They can be used for pre-market engagement only, but buyer’s can also use them to create a supplier shortlist for their further competition.

EOIs can help a buyer find out if suppliers are interested in bidding for their project, and can offer the products or services needed. If a supplier does not respond to an EOI, the buyer does not need to invite them to tender. You should check the framework rules first, not all frameworks allow you to carry out an EOI.
