Invitation to Tender

The Invitation to Tender is the document pack that defines what bidders must submit and how they will be evaluated. In Open Procedures, the ITT is published alongside the Contract Notice and is available to any interested supplier. In Restricted Procedures and other two-stage procedures, the ITT is issued only to shortlisted candidates after the selection stage. Either way, the ITT is the operational heart of the tender — far more detailed than the Contract Notice.

A typical ITT pack includes the technical specification, instructions to bidders, response templates, draft contract terms, pricing schedule, evaluation methodology, and any additional schedules (e.g., social value framework, security requirements, data protection annexes). The exact structure varies by contracting authority, but the underlying logic is consistent: the buyer specifies what it wants, how to respond, and how it will score.

For bid teams, the ITT triggers the full response cycle. Within hours of receiving it, the bid manager should produce a compliance matrix mapping every requirement to a section of the response, assign owners to each section, and schedule internal reviews. The structure of the response should follow the structure of the ITT exactly — deviation from the prescribed templates is a common reason for low scores, even when content is strong.

Clarification questions are the only sanctioned route to extra information once the ITT is issued. Questions and responses are usually shared with all bidders, so any question reveals strategic intent. Effective teams batch clarifications carefully and limit themselves to questions whose answer materially changes the response.

The ITT also exposes the evaluation framework — weights, scoring scales, sub-criteria, and minimum thresholds. The highest-weighted criteria deserve the most effort. Sections with hard minima (pass/fail) deserve early attention because a single failure can disqualify the whole bid regardless of other scores. Mapping effort to weights, not to the team's natural enthusiasm, is one of the highest-leverage decisions in any tender.

Forgent.ai parses ITTs into structured criteria, links them to bid library content, and drafts initial responses against each requirement — letting the bid team focus on win themes, evidence selection, and review rather than blank-page drafting.
