Use eCertis to connect a tender criterion with the relevant national evidence and issuer, illustrated by current French and Finnish tax guidance.
A foreign supplier can recognise the commercial requirement in a tender and still struggle to identify the document needed to prove a participation condition. The buyer may use a national certificate name with no obvious equivalent in the supplier's home country. eCertis helps investigate that gap by connecting the criterion, the evidence and the issuing authority. The useful outcome is an explainable evidence choice for the actual procurement.
The Commission's eCertis public guide organises the system around those three concepts. It covers information supplied by participating authorities in EU Member States and EEA countries and supports searches and comparisons across countries. The database is a research tool for understanding the evidence landscape; it is not the certificate issued to the individual company.
Read the criterion before searching for a document title. A requirement concerning tax compliance, professional registration or a particular selection capacity asks a different question in each case. Two certificates with similar names may cover different facts or time periods.
Consider a hypothetical Finnish consultancy bidding with a French partner for an administrative study. The lead receives a request for evidence concerning the participating businesses' tax position. The team should first identify the exact condition and which entities it concerns. Asking both companies for a document with the French title may obscure the Finnish authority's different terminology and process.
An internal evidence note can record the buyer's requirement, the entity concerned and the fact the proposed document is intended to establish. This creates a clear question for the country specialist or finance team. It also prevents a certificate concerning tax residence from being selected merely because the request contains the word tax.
The public guide describes country filters, searches for criteria, evidence and issuers, and comparison of selected records. It also identifies update information and links associated with the records. Use those features to understand which authority and document category are relevant to the requirement being investigated.
For the hypothetical consortium, the lead can compare the evidence associated with the relevant condition in France and Finland, then follow the issuing authority's current guidance. Record the source and review date, together with any question that remains open about the document’s scope or issuing process. If a database entry and an issuer's newer instructions differ, the discrepancy should be resolved rather than silently choosing whichever version seems easier.
Keep the research focused on the procurement. Exporting every available certificate category creates a large file without necessarily answering the supplier's question. A short record linking the exact criterion to one or more plausible forms of evidence is more useful to the bid team and to a buyer reviewing a clarification.
France's tax administration explains the attestation de régularité fiscale, with guidance updated in April 2026. It distinguishes routes depending on the business's tax situation and describes the relevant professional-account or tax-office process. That issuer guidance adds information that a translated certificate name cannot provide.
Finland's Tax Administration guidance, updated in July 2026, distinguishes a certificate of paid taxes from a certificate of tax debts. It explains that the documents describe facts known when issued and that historical-date certificates are not issued. Those distinctions matter when deciding what an existing document actually demonstrates.
The consortium should obtain the evidence corresponding to each company's situation and the buyer's request. It should not rename one certificate to make it sound like the other. Preserve the original title and explain the relevant content. The acceptance of evidence must be assessed under the procurement's applicable rules and instructions, with clarification where necessary.
The colleague who can request a document may not be the person best placed to explain its relevance to the tender. Finance may have access to the tax account; the bid lead understands the buyer's requirement; an authorised legal reviewer may need to assess an unresolved equivalence question. Connect those contributions rather than leaving the entire decision to whoever downloads the file.
For the hypothetical Finnish consultancy, the finance team can confirm the document's issuer, date and corporate identity. The commercial lead can compare its content with the requested condition. If a difference remains, they can formulate a precise clarification explaining what the document covers and asking what additional evidence, if any, is required.
That question is more useful than asking whether a foreign certificate is acceptable without identifying the document or the criterion. It gives the contracting authority something concrete to assess and helps the supplier avoid buying an unnecessary translation of the wrong record.
A document's issue date, the period it describes and the buyer's required evidence date are separate considerations. The supplier should identify all three before assuming that a certificate held from an earlier procurement remains suitable.
In the hypothetical consortium, one partner might have a recent certificate while the other holds a document obtained many months earlier. The team should check the actual requirement and issuer guidance before setting a common collection deadline. Where a fresh document is needed, obtain it through the relevant authorised process early enough for review and any required translation.
Do not treat a request for updated evidence as permission to alter the underlying document. Retain the issued original and keep any translation or explanatory note clearly separate. The evidence record should allow a reviewer to see what the authority issued and what the supplier has added to explain its relevance.
Article 61 of the January 2026 consolidated Public Procurement Directive provides for updated Member State information in eCertis and contracting authorities' use of the repository. That legal context explains why the tool belongs in cross-border evidence preparation, while the particular procedure still determines the supplier's response.
The ESPD consortium guide addresses the declarations about participants and relied-on entities. The evidence assembled here should substantiate the relevant declaration for the correct organisation. A document for a parent company should not be used without explanation as if it were issued for a separate subsidiary.
The PIC and LEAR guide covers a different identity record used in the Commission's participant system. A consistent corporate name and identifier help connect the records, but a participant registration does not replace the evidence requested for an exclusion or selection condition.
After resolving the procurement's evidence question, preserve the result in a form the company can reuse responsibly. Record the criterion investigated, issuing authority, official guidance and explanation of the selected evidence. Keep the procurement-specific acceptance or clarification alongside it, with its scope and date.
For the Finnish-French consortium, that record can save time on a later joint opportunity. It should still be reviewed against the new requirement and current issuer instructions. A previous buyer's acceptance is useful history, not a universal approval for every future procedure.
The practical value of eCertis is a better-informed evidence decision. The supplier can explain why a particular document addresses the requested fact, identify who issued it and recognise what remains unresolved. That gives a cross-border bid a more reliable foundation than matching certificate names by translation alone.
