What Is a Tender?

In public procurement, a tender (sometimes called a solicitation, invitation to tender, or call for tenders) is the formal process by which a contracting authority invites qualified suppliers to propose how they would fulfil a specific contract. The contracting authority publishes a notice that describes the requirement, sets out the rules of the competition, defines evaluation criteria, and establishes a deadline for submissions.

The word "tender" can refer both to the process itself and to the submission a supplier makes (as in "submitting a tender"). In practice, the context usually makes the meaning clear. The goal of any tendering process is to select the supplier who offers the best combination of quality, capability, and price — a concept known as the "most economically advantageous tender" (MEAT) in EU procurement law.

Tendering is mandatory for most public sector purchases above certain financial thresholds. In the EU, these thresholds are set by procurement directives and contracts above them must be advertised on TED (Tenders Electronic Daily). In the United States, federal procurement opportunities are published on SAM.gov. The United Kingdom uses Contracts Finder and Find a Tender for its domestic and above-threshold notices respectively. Most countries operate at least one national e-procurement portal for this purpose.

The terms tender, bid, proposal, and solicitation are frequently used interchangeably, which can be confusing — especially for companies entering public procurement for the first time. While the precise usage varies by country and context, here are the practical distinctions:

• Tender — the most common term in European, Commonwealth, and international procurement. It refers to both the buyer's invitation and the supplier's response. "Issuing a tender" means the buyer is inviting offers; "submitting a tender" means the supplier is responding.

• Bid — widely used in North American procurement and in informal contexts globally. A bid is essentially the supplier's offer. The process of deciding whether to pursue a tender is called a bid/no-bid decision.

• Proposal — typically refers to the supplier's detailed written submission, particularly in contexts that emphasise technical approach and methodology. A Request for Proposal (RFP) is the buyer's formal document inviting such submissions.

• Solicitation — the US federal procurement term for the buyer's formal request for offers. It encompasses RFPs, Requests for Quotation (RFQs), and Invitations for Bid (IFBs).

• ITT (Invitation to Tender) — the UK and Commonwealth equivalent, referring specifically to the buyer's document inviting suppliers to submit tenders.

Regardless of the terminology, the underlying principle is the same: a buyer describes a need, suppliers compete to fulfil it, and the contract is awarded based on pre-defined evaluation criteria. For a deeper comparison of these document types, see our glossary entry on ITT vs RFP vs RFQ.

Procurement law defines several formal procedures for conducting tenders. The procedure chosen depends on the complexity of the requirement, the value of the contract, and the degree of flexibility the contracting authority needs. The four principal types are:

• Open tender — any qualified supplier may submit a bid. This is the most common and most transparent procedure, used for straightforward requirements where the market is competitive. There is no pre-qualification stage; all submissions are evaluated against the published criteria.

• Restricted tender — a two-stage process in which suppliers first submit expressions of interest and pre-qualification information. The contracting authority shortlists candidates (typically five or more) and only those shortlisted are invited to submit full tenders. This is used when the buyer wants to limit the number of detailed submissions to reduce evaluation burden.

• Negotiated procedure — the contracting authority enters into direct negotiations with one or more selected suppliers. In EU procurement, this requires specific justification (such as urgency, technical exclusivity, or the failure of an open or restricted procedure). The negotiated procedure with prior publication is more common; without prior publication it is reserved for exceptional circumstances.

• Competitive dialogue — used for particularly complex contracts where the buyer cannot define the technical solution in advance. Suppliers are invited to participate in a structured dialogue to develop one or more solutions, after which they submit final tenders. This is common for large IT systems, PPP/PFI projects, and infrastructure concessions.

Additional mechanisms include framework agreements (pre-agreed terms for repeat purchases over a set period), dynamic purchasing systems (electronic systems that remain open to new suppliers throughout their duration), and innovation partnerships (for procuring goods or services that do not yet exist).

Every tender follows a structured lifecycle with defined stages, each governed by procurement regulations. Understanding this lifecycle is critical for suppliers because missing a deadline or misunderstanding a requirement at any stage can mean disqualification. The typical lifecycle is:

1. Need identification — the contracting authority identifies a requirement and defines the scope, budget, and timeline internally. At this stage, some authorities publish a Prior Information Notice (PIN) giving the market advance warning.

2. Publication — the authority publishes a formal tender notice on the relevant e-procurement platform. In the EU, contracts above threshold appear on TED and are classified using CPV codes. In the US, they appear on SAM.gov with NAICS codes. This is the stage where automated monitoring tools become invaluable — see the manual vs automated comparison.

3. Clarification period — suppliers review the tender documents and may submit questions. The authority publishes answers (visible to all bidders) to maintain a level playing field. This is the supplier's opportunity to seek clarification on ambiguous requirements.

4. Submission — suppliers prepare and submit their tenders before the deadline. Late submissions are almost always rejected regardless of quality. Submissions typically include a technical proposal, a commercial/pricing proposal, and supporting evidence of qualifications, capacity, and past performance.

5. Evaluation — an evaluation panel scores each submission against the published criteria (which may include quality, technical merit, price, social value, and environmental considerations). The panel may request clarifications but cannot negotiate terms during a standard open or restricted procedure.

6. Award and standstill — the authority selects the winning bidder and notifies all participants. In the EU, a mandatory standstill period (typically 10 calendar days) gives unsuccessful bidders time to challenge the decision before the contract is signed.

7. Contract execution — the signed contract is executed, and the authority publishes a Contract Award Notice disclosing the winner, the award value, and the number of bids received.

Tenders are issued by a wide range of organisations across the public sector and, in some cases, by private companies and international institutions. The main categories of contracting authorities are:

• Central government departments and agencies — national-level ministries, departments, and executive agencies (e.g., UK Ministry of Defence, US Department of Health and Human Services, France's Direction Generale de l'Armement).

• Sub-central and local government — state, regional, and municipal authorities, including city councils, county governments, and regional health authorities.

• Utilities and regulated entities — organisations operating in the water, energy, transport, and postal sectors, which are subject to dedicated procurement rules in many jurisdictions.

• International organisations — bodies such as the United Nations (via UNGM), the European Commission, the World Bank, and development banks issue tenders for projects worldwide.

• National Health Service (NHS) trusts and other public bodies — in the UK, NHS procurement alone represents billions of pounds annually in opportunities for healthcare suppliers.

The scale of public procurement is enormous. According to the OECD, public procurement accounts for 12-20% of GDP in most developed economies. In the EU, public procurement spending exceeds EUR 2 trillion annually. The US federal procurement market alone was worth over $750 billion in 2024. The UK public sector spends approximately GBP 300 billion per year. These figures represent a substantial and growing market for suppliers of all sizes, from multinational corporations to specialised SMEs.

Finding relevant tenders is one of the biggest challenges suppliers face. Opportunities are spread across hundreds of portals worldwide, published in different languages, using different classification systems, and with varying search capabilities. The main approaches to finding tenders are:

• Official procurement portals — every major economy operates at least one government procurement portal. The most important include TED (EU, 700,000+ notices/year), SAM.gov (US federal), Contracts Finder (England), and dozens of others. For a comprehensive overview, see our glossary entry on finding government tenders.

• National and regional portals — many tenders below international thresholds are published only on national or regional platforms. For example, German sub-threshold tenders appear on platforms like bund.de and state-level portals, while French opportunities are published on TED (above threshold) and BOAMP (below threshold).

• Automated tender monitoring — manually searching multiple portals daily is time-consuming and leads to missed opportunities. Platforms like Jorpex aggregate 50+ procurement sources and use AI-powered matching to deliver relevant tenders directly to Slack, email, or Microsoft Teams. The manual vs automated comparison quantifies the difference in coverage and response time.

• Buyer engagement and market intelligence — proactive suppliers build relationships with contracting authorities before tenders are published, attending industry days, responding to Prior Information Notices, and using Contract Award Notices for competitive intelligence.

The key to success is systematic, continuous monitoring rather than sporadic manual searching. With tender response windows often as short as 20-30 days (and sometimes less), early awareness is a decisive competitive advantage.
