Tender

A tender is a formal competitive process in which a buyer invites contractors or suppliers to submit priced proposals for a defined project or supply contract. The buyer issues an invitation to tender (ITT) containing the project scope, specifications, submission requirements, and a deadline. Respondents prepare and submit a priced bid - and the buyer evaluates submissions against stated criteria before awarding the contract.

Tendering is most common in construction, AV system installation, office furniture supply, and fit-out work - particularly for public sector projects, large corporate buyers with formal procurement policies, or any project above a buyer's internal approval threshold.

How the Tender Process Works

The buyer - or their appointed quantity surveyor or project manager - prepares a tender package. This typically includes drawings and specifications, a bill of quantities or schedule of works, a programme, contract conditions, submission instructions, and a deadline. Contractors who receive the ITT have a set period - typically two to six weeks for straightforward projects, longer for complex ones - to review the documents, carry out site visits, raise clarifications, and submit their bid.

A complete tender response includes a priced bill or schedule, a method statement, evidence of relevant experience, compliance documents such as insurance and accreditations, and any required programme. Submitting an incomplete tender is a fast route to disqualification before the buyer even reviews your price. Once submissions close, the buyer evaluates bids. On public sector projects, scoring typically combines price with quality, programme, and social value criteria.

Tender vs. Quotation: Key Differences

A quotation is typically issued in response to an informal request - a customer contacts you to discuss a project, and you prepare a price. There is no structured competitive process, no set evaluation criteria, and no formal submission deadline. A tender follows a defined competitive procurement process. Multiple contractors price the same documented scope. Submissions happen simultaneously with a fixed deadline, and award decisions follow a documented evaluation process.

The practical difference after award is equally important. Once a tender is accepted, the priced scope is locked to the tender documents. Any change must go through a formal variation order process. This makes scope clarity at tender stage critical: assumptions and exclusions must be stated explicitly in your submission, or they are unenforceable once the contract is signed.

Managing Your Tender Win Rate

Tender win rate - the percentage of submitted tenders resulting in contract awards - is an important efficiency metric. Most contractors win 40-50% of the tenders they enter; well-organized firms with strong processes reach 65% or more (Develop Coaching, 2025). A go/no-go assessment before committing bid time makes a significant difference. Score each opportunity on scope fit, contract value relative to bid cost, competition, and existing relationship with the buyer. Passing on a poor-fit tender is a better use of resources than submitting a rushed bid.

After each result - win or lose - request scoring feedback from the buyer. A consistent post-tender debrief over six to twelve months produces a clear picture of where bids succeed and where they lose points.
