To bid on an EU public contract, you follow four steps: find the relevant tender (on TED for above-threshold contracts and on national portals for the rest), check whether you are eligible and the contract is worth pursuing, prepare your offer against the published evaluation criteria, and submit it electronically before the deadline. Every above-threshold tender across the European Union runs through a formal, regulated procedure governed by Directive 2014/24/EU and national procurement law, so the process is broadly the same whether you are bidding in Germany, France, or Spain. The hard part is rarely writing the offer. It is finding the right tenders early and deciding which ones are genuinely worth your time.
This guide walks through the full EU bidding process step by step, explains how to find tenders and check eligibility, and shows where AI now does the heavy lifting so your team can focus on the bid or no-bid decision.
How to bid on EU public contracts: the four steps
Public procurement in Europe accounts for roughly 14% of EU GDP, about €2 trillion in annual spend. Capturing even a small share of it means treating bidding as a repeatable process rather than a scramble. Across the EU, that process has four stages:
- Find the tender. Identify contracts that match what your business sells, before the submission window closes.
- Check eligibility and fit. Confirm you meet the qualification requirements and that the contract is worth bidding on.
- Prepare the offer. Build a compliant, competitive response against the published criteria.
- Submit electronically. File the complete offer through the buyer's e-procurement system before the deadline.
Each stage has its own pitfalls. The sections below cover them in order. For the wider regulatory backdrop, see our explainer on the EU procurement process and what procurement is.
How to find EU tenders
The single biggest reason bidders lose contracts is not a weak offer. It is never seeing the tender in time. Opportunities are scattered across more than 4,500 portals and platforms in Europe, and no buyer is obliged to send them to you.
There are three layers to search:
- TED (Tenders Electronic Daily) is the EU's official journal for procurement. Every contract above the EU thresholds must be published here, which makes it the mandatory baseline for cross-border and high-value tenders. See our guide to TED for how the journal is structured.
- National and regional portals carry the larger volume of below-threshold contracts that never reach TED. These are fragmented across countries, regions, and sectors.
- Sector-specific platforms publish specialised tenders in fields such as construction, healthcare, or transport.
Tenders are classified by CPV codes, the EU's Common Procurement Vocabulary, which let you filter by the type of goods, services, or works on offer. Used well, CPV codes narrow thousands of daily notices to the handful that fit. Used as your only filter, they also miss relevant tenders that buyers have miscoded, which is common.
Because of the eForms standard, in force across the EU since late 2023, notices now follow a harmonised structure that makes automated matching far more reliable. This is where AI search changes the economics: instead of manually checking dozens of portals every morning, a profile-based search reads each new notice and surfaces only the ones that match your business, so nothing relevant slips through. Our Patterno Hit product is built for exactly this, covering TED, national platforms, and regional sources from a single search.
Eligibility for EU tenders: can you bid?
Before investing days in an offer, confirm you are actually allowed to win it. Under Directive 2014/24/EU, buyers assess bidders in three areas:
| Eligibility check | What the buyer verifies | Typical evidence |
|---|---|---|
| Exclusion grounds | No criminal convictions, unpaid taxes or social contributions, serious professional misconduct, or insolvency | Self-declaration, certificates, register extracts |
| Suitability | Authorisation to perform the activity, enrolment in a trade register | Trade or professional register entry |
| Selection criteria | Economic and financial standing, technical and professional capacity | Turnover figures, references, qualifications |
The mandatory and discretionary exclusion grounds are set out in the directive: a bidder caught by a mandatory ground (for example a conviction for fraud or corruption) must be excluded, while discretionary grounds (such as significant past contract failures) let the buyer decide.
In most EU procedures you provide this information up front through the ESPD (European Single Procurement Document), a standardised self-declaration that you meet the requirements. Only the bidder in line to win is then asked to produce the underlying certificates. The ESPD saves you from assembling a full evidence pack for every bid, but it has to be filled in accurately: a false declaration is itself an exclusion ground.
EU tender process steps: open versus restricted procedures
The procedure the buyer chooses determines how you bid and on what timeline. Two dominate.
In an open procedure, any interested supplier may submit a full offer in a single stage. There is no pre-selection, so the field can be large, but you only have to act once. This is the standard procedure for above-threshold contracts.
In a restricted procedure, bidding happens in two stages. First you submit a request to participate and your qualification evidence. The buyer then invites a shortlist of qualified candidates to submit full offers. This rewards bidders who can demonstrate strong references and capacity early.
Buyers also use negotiated procedures, competitive dialogue, and innovation partnerships for more complex or novel requirements, but the open and restricted procedures cover the large majority of routine contracts. Where a contract is a framework agreement, winning it places you on a list from which the buyer can call off orders over several years, often the most valuable outcome of all.
How to respond to a tender and prepare a winning offer
Once you have decided to bid, preparation is about compliance first, persuasion second. An offer that misses a mandatory document or a formal requirement is rejected before anyone reads your pricing.
A disciplined response covers five things:
- Read the full tender pack. Specifications, contract terms, evaluation criteria, and submission rules. The award criteria, and their weightings, tell you exactly what the buyer will score.
- Build a compliance checklist. List every required form, certificate, and declaration, then assign an owner and a deadline to each.
- Answer the criteria directly. Structure your offer to mirror the published evaluation grid so evaluators can find and score each point.
- Price deliberately. Most awards use the "most economically advantageous tender" test, which weighs quality against price, so the lowest bid does not automatically win.
- Allow time for review. Late or incomplete submissions are not accepted, full stop.
This stage is where AI now removes the most grind. Document-analysis tools read a full tender pack in minutes and surface deal-breakers such as restrictive eligibility clauses, missing certifications, or unrealistic timelines before your team commits. Our Patterno Bid product supports this analysis and qualification work. The principle stays the same throughout: AI prepares and qualifies, and the human makes the final bid or no-bid call.
Submitting your bid
Almost all EU public tenders are submitted through electronic procurement systems, a practice often called e-procurement. You register on the buyer's platform, upload your documents, and confirm submission before the deadline shown in the notice. Allow for the platform to be slow under load near the deadline, and never plan to submit in the final hour. Once the window closes, the system locks, and there is no appeal for a late upload.
How AI helps you bid on more contracts
The bottleneck in public bidding is capacity. A team can only research, qualify, and write so many offers. By automating discovery across more than 4,500 European portals and accelerating document analysis, AI lets the same team pursue the tenders worth winning instead of the ones they happened to find. Purpose-built tender software for the EU market turns bidding from a reactive scramble into a managed pipeline.

Frequently asked questions
How do I find public contracts to bid on in the EU?
Above-threshold contracts must be published on TED (Tenders Electronic Daily), the EU's official procurement journal. Below-threshold contracts appear on national and regional portals, of which there are more than 4,500 across Europe. You can filter tenders by CPV code, the EU's classification for goods, services, and works, or use an AI search platform that matches new notices to your business profile across all sources at once.
Who is eligible to bid on EU public contracts?
Any economic operator that is not caught by the exclusion grounds in Directive 2014/24/EU, can prove it is authorised to carry out the activity, and meets the buyer's selection criteria for economic, financial, technical, and professional capacity. Bidders declare this through the European Single Procurement Document (ESPD), a standardised self-declaration, and only the prospective winner has to produce the supporting certificates.
What is the difference between an open and a restricted procedure?
In an open procedure, any supplier may submit a full offer in one stage with no pre-selection. In a restricted procedure, you first request to participate and submit qualification evidence, and the buyer then invites a shortlist of qualified candidates to bid. The open procedure is the standard route for above-threshold contracts in the EU.
How long does the EU tender process take?
It varies by procedure and contract value. EU directives set minimum time limits for suppliers to respond, typically several weeks for above-threshold open procedures, plus a mandatory standstill period after the award decision so unsuccessful bidders can challenge it before the contract is signed. Always work backwards from the exact deadline in the contract notice.
Does the lowest price always win a public tender?
No. Most EU contracts are awarded on the "most economically advantageous tender" basis, which weighs quality, technical merit, and sometimes sustainability against price using criteria the buyer publishes in advance. A higher-priced offer can win if it scores better on the published criteria, which is why answering each criterion directly matters more than simply bidding low.
Can AI submit a bid for me?
No, and it should not. AI tools find relevant tenders, analyse the documents to flag eligibility issues and deal-breakers, and help draft structured responses against the evaluation criteria. The bid or no-bid decision, the commercial judgement, and the final submission stay with your team. AI removes the manual research and review work so people can focus on the parts that need expertise.
