How to Respond to an EU Open Procedure

The open procedure, defined in Article 27 of Directive 2014/24/EU, is the most common and most accessible procurement method in the European Union. Any qualified company can submit a tender — there is no pre-qualification stage, no shortlisting, no invitation required. You see the contract notice, you prepare your bid, you submit it by the deadline.

This accessibility comes with a challenge: you get one shot. Unlike restricted procedures where you can test the waters with a pre-qualification submission, an open procedure requires you to invest fully upfront — technical proposal, pricing, qualification evidence — without knowing how many competitors you face or whether you have a realistic chance of winning.

This guide walks you through the entire process, from the moment you identify an opportunity to the standstill period after contract award.

The Open Procedure Timeline

Understanding the timeline helps you plan your resources. For a comprehensive breakdown of deadlines across all procedure types, see our procurement timelines guide.

Day 0:    Contract notice published on TED
Day 1-5:  Download documents, initial assessment, go/no-go decision
Day 5-10: Prepare clarification questions (if needed)
Day 10-15: Receive answers to clarifications
Day 15-30: Prepare technical proposal and ESPD
Day 25-33: Prepare pricing, review, quality check
Day 33-35: Final review and electronic submission
Day 35:   Submission deadline
Day 35-90: Evaluation period (buyer's side)
Day 90+:  Award decision and standstill period

Standard minimum deadlines:

• 35 days from notice dispatch (standard)
• 30 days if electronic submission is available (common)
• 15 days if a prior information notice was published (reduced timeline)

In practice, many contracting authorities give 40-60 days for complex procurements.

Step 1: Download and Review Tender Documents

When you identify a relevant opportunity (whether from TED, a national platform, or through a tool like Duke), your first action is to download the complete tender documentation.

What you will typically receive

• Tender instructions (Instructions to Tenderers) — The procedural rules: how to structure your bid, what to include, format requirements, submission method
• Technical specifications — What the buyer actually needs, in detail
• Terms of reference (for services) — Scope, deliverables, milestones, performance requirements
• Draft contract — The legal terms you will be bound by if you win
• ESPD template — The pre-filled self-declaration form
• Pricing schedule — The format for your financial offer
• Evaluation criteria — How bids will be scored (critical for strategy)
• Annexes — Site plans, existing system documentation, data formats, and other supporting material

Where to find documents

Documents are typically available through:

• A link in the TED notice to the buyer's e-procurement platform
• The national procurement platform where the notice was published
• Direct download from the buyer's website (less common for above-threshold)

You may need to register on the buyer's e-procurement platform to access documents. Do this immediately — registration delays can eat into your preparation time.

Step 2: Make the Go/No-Go Decision

Before investing 100+ hours in bid preparation, make a structured decision about whether to proceed. Use the bid evaluation framework for a detailed approach.

Quick go/no-go checklist

• CPV match: Do the CPV codes align with your core offerings? (See our CPV code guide for search strategies.)
• Geographic fit: Can you deliver at the specified location?
• Value fit: Is the contract value in your sweet spot?
• Qualification fit: Do you meet turnover, experience, and certification requirements?
• Timeline fit: Can you prepare a quality bid in the available time?
• Competition assessment: Is the field likely to be open, or does this look tailored?
• Strategic fit: Does this contract advance your business strategy (reference, market entry, revenue)?

If any of the first four are a clear "no," stop here and save your resources for the next opportunity.

Step 3: Prepare the ESPD

The European Single Procurement Document (ESPD) is a standardized self-declaration that covers your eligibility and qualifications.

What the ESPD covers

Part II: Information about the economic operator

• Company identification, registration numbers, VAT
• Key personnel involved in the bid
• Subcontractors (if any)

Part III: Exclusion grounds

• Criminal convictions (fraud, corruption, money laundering, terrorism)
• Tax obligations (taxes paid, social security contributions current)
• Professional misconduct
• Bankruptcy, insolvency, winding-up proceedings
• Conflicts of interest

Part IV: Selection criteria

• Suitability (professional register enrollment, authorizations)
• Economic and financial standing (turnover, financial ratios, insurance)
• Technical and professional ability (references, experience, staff, equipment)
• Quality assurance and environmental management standards

Part V: Reduction of candidates Not applicable in open procedures (used only in restricted procedures).

Part VI: Concluding statements Signature and date.

ESPD preparation tips

• Use the electronic ESPD service at espd.oecd.org or the buyer's platform. This generates a structured XML/PDF that the buyer can process electronically.
• Be truthful. The ESPD is a self-declaration. If you win, you will be asked to provide actual certificates and evidence. Discrepancies between declaration and evidence will result in exclusion and potential blacklisting.
• Prepare a master ESPD. Keep a template ESPD with your standard company information pre-filled. For each tender, you only need to adjust the buyer-specific and contract-specific sections.
• List all relevant references. Even if the buyer asks for three references, having additional ones in your files helps if they request supplementary evidence.

Step 4: Prepare Your Technical Proposal

The technical proposal is where you differentiate yourself. This is the substance of your bid.

Structure (typical)

1. Executive summary — One-page overview of your understanding and proposed approach
2. Understanding of requirements — Demonstrate you understand what the buyer needs (not just what they wrote)
3. Proposed methodology/approach — How you will deliver the work or supply the goods
4. Work plan/delivery schedule — Timeline, milestones, deliverables
5. Team/resources — Who will deliver the work, their qualifications, availability
6. Quality management — How you ensure quality throughout delivery
7. Risk management — Key risks identified and your mitigation approach
8. Added value — What you bring beyond the minimum requirements

Critical rules

• Follow the structure prescribed in the tender documents. If the buyer specifies sections and page limits, follow them exactly. Evaluators use the structure to find information — if it is in the wrong place, it may not be scored.
• Answer every question. If the evaluation criteria mention "approach to knowledge transfer" and you do not address it, you score zero on that criterion.
• Be specific. "We have extensive experience in similar projects" scores lower than "We delivered a comparable system for [type of organization] in 2024, serving 5,000 users, achieving 99.8% uptime."
• Respect page limits. Exceeding them risks disqualification in strict procedures, and always frustrates evaluators.

Step 5: Prepare Your Financial Offer

The financial offer must follow the pricing schedule provided by the buyer exactly.

Common pricing formats

• Lump sum — Total fixed price for the deliverable
• Unit prices — Price per unit (hour, item, day), multiplied by estimated quantities
• Framework pricing — Rate card for different resource types, applied to call-offs
• Mixed — Combination of fixed elements and variable pricing

Pricing strategy

• Study the award criteria weights. If price is 40% and quality is 60%, a slightly higher price with superior quality can win. If price is 70%, you must be competitive.
• Check abnormally low tender provisions. Most tender documents specify that the buyer can reject tenders that appear abnormally low. Pricing below cost to win is risky — you may be asked to justify, and implausible explanations lead to exclusion.
• Factor in all costs. Travel, accommodation, training, warranty, support. Omitting costs that will arise during delivery either erodes your margin or forces you to underperform.
• Use the buyer's template. Do not create your own pricing format. Fill in the provided schedule exactly as instructed.

Step 6: Assemble and Submit

Assembly checklist

Before submission, verify you have:

• ESPD completed and signed (electronic or physical as required)
• Technical proposal in prescribed format, within page limits
• Financial offer using the buyer's pricing schedule
• All requested certificates and declarations
• Company registration documents
• Insurance certificates (if required)
• References with contact details
• Signed declaration of honor / conflict of interest statement
• Required number of copies (digital, physical — check the instructions)

Electronic submission

The vast majority of above-threshold EU procurement now requires electronic submission through e-procurement platforms.

Key technical considerations:

• Register early. Most platforms require registration and sometimes approval before you can submit. Do this when you download the documents, not the day before the deadline.
• Test the system. Many platforms allow test submissions. Use this feature to understand the upload process, file size limits, and format requirements.
• File formats. PDF is standard for documents. The pricing schedule may need to be submitted in Excel or the platform's own format. Do not submit in formats not specified.
• File size limits. Large technical proposals with images can exceed upload limits. Compress files in advance.
• Timestamp. The platform's clock is authoritative. Submit at least 24 hours before the deadline. Last-minute submissions risk technical failures (platform overload, network issues) with no recourse.
• Confirmation. Ensure you receive a submission receipt or confirmation number. Screenshot everything.

Post-submission

After submission, you generally cannot modify your tender. The waiting period begins. During evaluation:

• The buyer may request clarification on specific points (you must respond within the specified timeframe, without changing the substance of your offer)
• You may be asked to provide certificates backing up your ESPD self-declarations
• The evaluation panel scores all tenders against the published criteria

Step 7: Understand Evaluation and the Standstill Period

How evaluation works

The evaluation panel (typically 3-5 evaluators) scores each tender against the published criteria. The process varies but typically:

1. Administrative compliance check — Is the tender complete, on time, signed, in the right format?
2. Exclusion and selection criteria — Does the tenderer meet the minimum qualification requirements?
3. Quality/technical evaluation — Scoring the technical proposal against published criteria and sub-criteria
4. Financial evaluation — Scoring the price (usually lowest price gets maximum points, others proportionally less)
5. Combined scoring — Quality and price scores combined using the published weightings
6. Abnormally low tender check — If any price seems unrealistically low

The award decision

The contracting authority notifies all tenderers of the award decision simultaneously. You will receive:

• The name of the winning tenderer
• The reasons your tender was not selected (including your score and the winning score)
• The standstill period dates

The standstill period

The standstill period is a mandatory waiting period between the award decision and contract signing. It exists to give unsuccessful tenderers time to challenge the decision.

• Duration: Minimum 10 days (15 days if notification was not electronic)
• Your rights: During this period, you can request a full debrief on the evaluation, review your scores versus the winner, and file a complaint if you believe the process was unfair
• Challenge mechanism: If you believe there was a procedural error, you can apply to the review body identified in the contract notice for rapid interim measures

After the standstill period

If no challenge is filed, the buyer signs the contract with the winning tenderer. If a challenge is filed, the process is suspended until the review body rules.

Common Mistakes That Lose Bids

Not reading the tender instructions completely. Hidden requirements buried on page 47 of the instructions — a specific declaration, a required format, a signature requirement — can make your entire submission non-compliant.

Submitting a generic proposal. Evaluators can tell when a proposal has been recycled from another bid. Tailor every section to the specific requirements, buyer, and context described in the tender documents.

Missing the deadline. Even by one minute. Electronic platforms lock automatically. There is no grace period, no appeal, no exception. Plan for technical problems by submitting early.

Not asking clarification questions. If anything in the tender documents is ambiguous, ask. Questions are submitted through the e-procurement platform, and answers are shared with all tenderers. Not asking means guessing — and guessing wrong means scoring low.

Ignoring the evaluation criteria weights. If methodology is worth 40% and team is worth 20%, invest proportionally in your proposal. Many companies write detailed team CVs (easy to produce) and thin methodology sections (hard to write). This is backward.

Underpricing to win. Abnormally low tenders get investigated. Even if you survive the investigation, delivering at a loss damages your reputation and your business.

How Duke Helps

Duke supports the open procedure response process at every stage:

• Early opportunity identification — Find relevant contract notices across TED and national platforms before your competitors, with enriched data and relevance scoring
• Buyer intelligence — Before you bid, understand the contracting authority's procurement history, past award values, and preferred supplier patterns
• Competition insight — See who has won similar contracts, how many bidders typically compete, and what price ranges succeed
• Deadline management — Track submission deadlines across your active bid pipeline with team visibility
• Post-award analysis — When award notices are published, Duke captures the data so you can analyze winning prices and competitors for future bids

Conclusion

Responding to an open procedure is a structured process with clear stages: assess the opportunity, prepare the ESPD, write a targeted technical proposal, price competitively, assemble meticulously, and submit early. Each stage has specific rules, and failure at any stage — even administrative compliance — can eliminate an otherwise strong bid.

The companies that consistently win open procedures are not just those with the best technical solutions. They are the ones with disciplined processes that ensure complete, compliant, well-targeted submissions every time. Process reliability — not occasional brilliance — is what drives consistent win rates in government procurement.

Build your process around this guide, refine it after every bid (win or lose), and invest in understanding each buyer's specific requirements. Over time, your conversion rate from opportunity identification to contract award will steadily improve.
