Last reviewed April 2026
The formal invitation, with full specification and contract terms, sent to qualified bidders.
An ITT is the formal invitation issued to suppliers (either openly or to those shortlisted from a prior selection stage) to submit priced, technical bids on a contract. It contains the specification, instructions to tenderers, the draft contract, the evaluation criteria, and the deadline. In Ireland, the term is largely interchangeable with Request for Tender (RFT) on eTenders.
