Expression of Interest
An Expression of Interest (EOI) is used to gauge interest from potential suppliers for a project you have on the drawing board or hope to tender in the near future. By issuing an EOI, you are given the opportunity to pre-qualify vendors capable of completing the work under the restrictions or specifications outlined in your proposal.
Is an EOI similar to or the same as a RFP (Request for Proposal), RFI (Request for Information)? Basically, yes they can be construed as being the same, with the exception of the potential legal ramifications so seek counsel or legal advice to ensure you understand how issuing any of the above will impact your company in the country, state or province you operate your business in.
