Tender Process

A tender process is a structured invitation for suppliers to compete for a contract under stated requirements and evaluation rules, used by private buyers and public bodies whose legal obligations differ. The process may include prequalification, tender documents, questions, submission, evaluation, clarification and award.

A tender improves comparability only when the buyer defines the need clearly and follows a fair method. Start with a specification that describes the required outcome, scope, location, timetable and service standards, because a vague request produces bids that cannot be compared and requirements should not be written around a preferred supplier without a legitimate reason.

Give bidders enough information to price risk, including known site conditions and contract terms, and say so where information is uncertain. Choose the right market approach: an open tender invites a broad field, a restricted tender may shortlist qualified suppliers, and a request for quotation for a routine purchase may not need the same procedure as a major construction project.

Procurement policy and, for public bodies, applicable law can dictate the route, so do not assume "three bids" is a universal legal requirement. CIPS describes a tender process and separate evaluation practices, and its material supports setting criteria in advance and comparing bids consistently.

The buyer should explain which requirements are mandatory, how quality and price will be weighted and whether interviews or demonstrations form part of the assessment, because changing weights after seeing bids can undermine fairness. A bidder should read every instruction before pricing, since submission deadline, file format, required declarations, signatures and bid validity may be strict and a missing mandatory document can disqualify an otherwise attractive offer.

Set an internal deadline earlier than the official cutoff to allow review and upload problems, and keep confirmation that the bid was submitted. Questions from bidders can reveal ambiguities, so share material clarifications fairly with all bidders who should receive them, subject to confidentiality rules, issue an addendum and adjust the deadline when necessary, and record the version of documents each bidder used.

Evaluation should use evidence, so price can include installation, support, maintenance and disposal costs, not only the initial quote, and quality can cover capacity, experience, proposed team and method. Test references and assumptions rather than awarding points for polished language, because a low price is not good value if it excludes essential work.

A weighted score can help structure comparison: if price receives 40% and quality 60%, a bid scoring 80 on price and 90 on quality has 32 plus 54, or 86 out of 100, though this does not prove it is the best choice unless the scores, weights and mandatory gates were set sensibly and applied consistently, and the reasons behind scores should be recorded. Clarifications after bids should explain an offer, not let one bidder secretly rewrite it while others cannot, and because negotiation rules vary by tender type and jurisdiction, with public procurement particularly prescriptive, the buyer should obtain procurement or legal advice when the route is regulated.

Before award, verify supplier identity, licences, insurance, financial capacity and conflicts as appropriate, review the proposed contract, exclusions and mobilisation plan, and manage the gap between a preferred bidder and a signed supplier. For a bidder, pricing must cover delivery cost and risk, because winning by underpricing can create a loss and pressure to cut quality or seek claims later, so a useful tender process protects both sides from moving targets, though it cannot guarantee the lowest price or a successful project.
