Tender

A tender is a formal, structured offer made by a supplier in response to a public procurement opportunity. The same word also describes the procurement process itself, where a buying authority publishes a notice, receives competing offers, and selects the most suitable supplier. In everyday business language, going to tender or putting something out to tender refers to the act of starting this competitive procurement process.

What is a tender in public procurement?

In public procurement, a tender is the document a supplier submits to a contracting authority in response to a published procurement notice. The tender contains the supplier's price, technical proposal, qualifications, and any required compliance evidence. The buying authority evaluates all received tenders against published criteria and awards the contract to the winning supplier.

Public procurement tenders exist because government bodies, state-owned enterprises, and other public institutions are required by law to procure goods, services, and works through transparent competition. This obligation applies across the European Union, the United Kingdom, the United States, and most developed economies. Suppliers who win tenders gain access to stable, multi-year revenue streams from public-sector clients.

How a tender process works

Most public tender processes follow a predictable sequence. First, the contracting authority identifies a need, defines specifications, and publishes a contract notice on a national procurement portal such as TED for the European Union, Contracts Finder in the United Kingdom, or SAM.gov in the United States. The notice describes what the authority wants to buy, the estimated value, and the submission deadline.

Suppliers who meet the eligibility criteria prepare their tenders. This preparation typically takes between two and six weeks depending on the complexity of the contract. Suppliers gather corporate documents, draft technical responses, calculate prices, secure tender bonds where required, and translate documents if the tender is in a foreign language. The completed tender is submitted before the deadline through the buyer's electronic platform.

After the deadline closes, the contracting authority opens all tenders, evaluates them against published award criteria, and selects the winner. The standstill period that follows allows other bidders to challenge the decision before the contract is signed. Once standstill ends without challenge, the contract is awarded and an award notice is published.

Types of tenders you will encounter

Tenders vary by procedure, sector, and value threshold. Open tenders allow any qualified supplier to submit a bid. Restricted tenders involve a pre-qualification stage where only shortlisted suppliers proceed to bid. Negotiated procedures permit dialogue between the buyer and bidders. Framework agreements establish a list of approved suppliers from which mini-competitions are run for specific contracts.

By value, tenders are split into above-threshold and sub-threshold contracts. Above-threshold tenders must follow strict EU directives and be published on TED. Sub-threshold contracts have lighter requirements but still demand transparency. By sector, tenders cover construction, IT, healthcare, defence, consulting, energy, and dozens of other categories, each with its own documentation conventions.

Common challenges suppliers face

• Document preparation takes longer than expected, especially for first-time bidders.
• Tender requirements often demand specific certifications, financial guarantees, and references that small suppliers may not have ready.
• Foreign-language tenders require translation, which adds cost and delays.
• The decision on whether to bid at all is itself difficult, since tender preparation can cost thousands of euros with no guarantee of success.

How tender intelligence platforms help

Modern procurement intelligence platforms aggregate tender notices from dozens of national portals into a single feed. Suppliers can filter opportunities by industry, geography, value, and deadline, and receive alerts when relevant tenders are published. Advanced platforms also analyse the buying authority, identify likely competitors based on past awards, and score the relevance of each tender against the supplier's profile.
