How to Prove Eligibility Criteria in Tenders

What eligibility evidence contracting authorities require and how to compile it correctly.

Steps Overview

  1. 1

    Identify Requirements

    Read the notice and identify all required criteria across professional capacity, economic standing, and technical capability.

  2. 2

    Gather Evidence

    Compile all required documents: trade register extract, revenue statements, references, certificates.

  3. 3

    Prepare Self-Declarations

    Complete the prescribed self-declarations regarding exclusion grounds (§ 123/124 GWB) in full.

  4. 4

    Prepare References

    Compile references in the required format. Ensure comparable services and the required time period.

  5. 5

    Check Currency

    Ensure all evidence is current. Many certificates must not be older than six months.

  6. 6

    Consider Resubmission Options

    Distinguish between evidence that can be requested later and documents that must be submitted with the bid.

Proving Eligibility Criteria

The eligibility check is the first step in bid evaluation. Only bidders meeting all criteria proceed to content evaluation. This guide shows you how to prove your eligibility professionally.

Which three eligibility categories does procurement law distinguish?

Procurement law distinguishes three categories:

1. Professional capacity: Trade register extract, professional registrations, industry-specific licenses 2. Economic and financial standing: Revenue from last three years, insurance coverage, bank references 3. Technical and professional ability: References, staff qualifications, equipment, quality management (ISO 9001)

What is the difference between a self-declaration and an evidence document?

  • Self-declarations: Bidder confirms requirements are met (no insolvency, no misconduct). Submit with bid.
  • Third-party certificates: Evidence from authorities (tax office, trade association). Often requested only from the preferred bidder.

Can missing eligibility documents be requested later?

Since the 2016 procurement reform, missing documents can be requested after submission (§ 56 VgV). However, this is at the authority's discretion and typically has a short deadline. Better to submit everything complete from the start.

How does prequalification save time when proving eligibility?

Prequalification (PQ) lets you centrally register common evidence. This saves you from resubmitting standard documents for every tender.

How do I organize my eligibility evidence efficiently?

  • Maintain an eligibility folder with standard documents, updated quarterly
  • Prepare reference sheets in a standardized format
  • Check certificate validity periods (usually 6 months)
