Participating in public or private tenders offers companies significant opportunities, but also poses risks if avoidable mistakes are made. Especially in SMEs and for freelancers, the tendering process consumes valuable resources, and formal or content-related errors often lead to disqualification. In this article, we outline the ten most common pitfalls, explain their causes, and offer practical advice for submitting error-free bids in the future.
Properly estimating timelines is crucial in tendering. Many bidders underestimate how long it takes to set up technical access (e.g., in an eTendering system) or activate ID-based access, causing them to miss critical deadlines. Moreover, legal deadlines for clarification requests must be strictly followed—at least six calendar days before the submission deadline (four for non-open procedures). Using internal workflows with set milestones and buffer times, plus early system registration, helps reduce deadline stress and technical risks. [1][2]
Formal requirements may seem trivial but are often deal-breakers. Missing a signature or using the wrong form can result in immediate disqualification. Key tips:
Use a four-eyes principle and a digital checklist to minimize critical oversights. [3][4]
Required qualification documents (e.g., balance confirmations, ISO certifications, reference lists) are essential. Missing documents can invalidate your bid. Use a gap scanner in your document management system and proactively request permission to submit delayed files, to avoid disqualification. [5][6]
The service description is your foundation. Unclear or incomplete descriptions can lead to planning errors, incorrect quantities, or liability risks. Ask:
Flag ambiguities and submit formal bidder questions to protect against future claims. [7][8]
Suitability criteria (e.g., experience, capacity) must be clearly separated from award criteria (e.g., price, quality). Referencing a project in price evaluation is not permitted. Structure your bid as follows:
Provide a separate table of contents to help reviewers. [9][10]
Do not interpret unclear parts on your own—the bidder bears the risk. Submit formal questions within the deadline (at least six days before the deadline). Even if you miss it, you can still challenge unclear sections legally, which may lead to deadline extensions. [11][12]
Typos or spreadsheet issues can be costly—a misplaced comma may drastically alter your pricing. Remember:
Use:
This minimizes surprises during submission. [13][14]
You must not manipulate item prices (e.g., underprice one and overprice another) to make the total look attractive. If identified, your bid will be rejected. Instead:
This keeps your pricing compliant and credible. [15][16]
Beyond forms and formats, there are legal requirements: general procurement principles (transparency, non-discrimination) and sector-specific laws (e.g., VOB/A, UVgO, GDPR). Lack of awareness leads to disqualification. Regular training and legal support help:
Ensure legal certainty at every stage. [17][18]
Bids don't exist in a vacuum—without market insight, your pricing may be off. Consider:
Only with this data-driven approach can you improve your bid success rate. [19][20]
The ten most common mistakes in tendering can be avoided through structured processes, clear responsibilities, appropriate tools, and legal expertise. Use checklists, automate repeat tasks, and train your team regularly—this will boost your success rate and save time and resources.
This article explores why public tenders in Europe represent a major business opportunity: The market amounts to around €2 trillion annually and accounts for approximately 14% of the EU’s GDP. Public procurement processes offer long-term planning security, high transparency, and foster innovation through non-price criteria. The construction sector alone sees over 200,000 contracts annually worth around €100 billion, while digital solutions and IT services are booming due to automation initiatives. In healthcare, tenders account for about half of all public spending and around 14% of GDP. Standardized procedures (open, restricted, negotiated, and innovation partnerships) with clear thresholds (e.g., €143,000 for services, €5.38 million for construction) shape market access.
Public IT tenders offer immense potential for companies of all sizes – from enterprises to SMEs and freelancers. But fragmented procurement portals, complex legal frameworks, and tight deadlines often lead to missed opportunities. This article shares proven, practice-based strategies to help you find relevant tenders, bid effectively, and significantly boost your success rate.
