This guide shows how to design stages, supplier dialogue and decision records that remain fair and auditable. The Procurement Act 2023 allows contracting authorities to design a competitive flexible procedure around the requirement. It can include participation stages, dialogue, negotiation, demonstrations and final tenders. That freedom is useful for complex services, but it increases the importance of explaining the process before suppliers invest in it. A defensible procedure has a clear route from notice to award. Suppliers should know when they may be removed, what information will be assessed, how the requirement may be refined and when a final offer will be requested. Officers should be able to show that the published process was followed consistently. ## When is a flexible procedure justified? Start with the problem to be solved. If the authority can state its requirement and assess complete tenders without interaction, an open procedure may be simpler. If the solution or risk allocation needs structured discussion, a flexible procedure may create better outcomes. The [Cabinet Office guidance on competitive tendering](https://www.gov.uk/government/publications/procurement-act-2023-guidance-documents-define-phase/competitive-tendering-procedures-html) describes both procedures and provides example designs; it does not prescribe a single template. The business case should explain why each stage adds value. A negotiation stage included only because it is available creates time and fairness risks without necessarily improving the result. ## Draw the stage map before publishing the notice Write a one-page sequence showing: initial information; any request to participate; conditions and objective shortlisting criteria; tender stages; dialogue or negotiation points; revised submissions; final tender; assessment; and award. State who makes each decision and what record will be retained. The tender notice and associated documents must give suppliers enough information to understand the nature and scope of the requirement. Before tenders are invited, the authority must be satisfied that the documents provide sufficient information for tenders to be prepared. Do not leave a material selection or scoring rule to be invented after bids arrive. Minimum time periods still apply. The [Cabinet Office time-period guidance](https://www.gov.uk/government/publications/procurement-act-2023-guidance-documents-procure-phase/time-periods-html) notes that periods can be longer where documents are not available with the notice or electronic submission is unavailable. Build a realistic timetable for clarifications and internal approvals, not only the minimum permitted days. ## Separate dialogue from negotiation Dialogue can improve mutual understanding of the requirement and possible solutions. Negotiation seeks to improve the content of tenders. Both need a defined purpose, trained participants and a reliable record of what was discussed. The authority should decide in advance which matters may be explored, which are fixed and how material information will be shared consistently where it affects all bidders. Protect suppliers' confidential information. Do not reveal one bidder's distinctive solution to a competitor. At the same time, avoid giving one bidder an unfair informational advantage through private clarification of a common requirement. Keep a decision log for changes to the specification, pricing schedule or evaluation approach. ## Use objective gates when reducing the field If the procedure reduces the number of suppliers, publish the relevant criteria and explain how they operate. Moderation notes should show how evidence was applied against the stated method, especially around marginal decisions. The [official learning module](https://www.gov.uk/government/publications/the-official-procurement-act-2023-e-learning/module-4-competitive-flexible-procedure) illustrates several possible stages, but the authority must choose a proportionate design for its own contract. A “preferred supplier” stage is not a second chance to rewrite the competition outcome. Any final clarification or negotiation must remain within the published process and the applicable rules. ## Control changes while the competition is live Complex procurements evolve. Section 31 and the [guidance on modifying a competitive procurement](https://www.gov.uk/government/publications/procurement-act-2023-guidance-documents-procure-phase/modifying-a-competitive-procurement-html) set rules for changing the terms. Before issuing a revised document, ask whether the change is permitted, whether suppliers need more time, and whether the notice must be updated. Record the reason, approval and communication to all affected suppliers. ## What should the final file show? A reviewer should be able to follow the original stage map, notices and documents, supplier communications, attendance and notes from dialogue, versions of the requirement, shortlisting and assessment records, and each approval to move forward. The file should explain why a supplier progressed or did not progress without relying on an officer's memory. The benefit of flexibility is a procedure shaped to the requirement. Its credibility comes from advance disclosure, proportionate stages and disciplined records. Our [earlier discussion of negotiation](https://prestigecommercialconsulting.co.uk/articles/negotiation-under-the-procurement-act-2023-when-councils-can-use-it-and-how-to-stay-compliant) covers that individual technique in more detail.
