What is OpenPeppol?
2.5 million participants across 111 countries, served by 300+ Access Points
OpenPeppol is the non-profit association (AISBL under Belgian law) that governs the Peppol network. It was established on 1 September 2012, taking over from the EU-funded PEPPOL project that had built the original infrastructure for cross-border electronic procurement and invoicing across European public administrations.
The association is member-led, with representatives from governments, service providers, and standards organisations setting its direction. As of early 2026, the network connects over 2.5 million participants from 111 countries, served by more than 300 certified Access Points operating in 98 countries. OpenPeppol manages the Peppol BIS (Business Interoperability Specifications), the PKI trust model that underpins secure message exchange, and the Peppol Interoperability Framework that ties it all together.
OpenPeppol works closely with 20+ national Peppol Authorities - government bodies that manage Peppol adoption within their jurisdictions. These authorities handle local policy, onboarding, and compliance, while OpenPeppol maintains the global rules and technical standards. This federated governance model has been a key factor in Peppol's expansion beyond its European roots into Asia-Pacific, the Middle East, and the Americas.
What is GENA?
GENA (Global Exchange Network Association) is the international trade body representing e-invoicing service providers. It was formerly known as EESPA (European E-Invoicing Service Providers Association), which was founded in 2011. The rebrand to GENA took place in October 2023, reflecting the association's expansion well beyond its original European focus.
GENA is an international not-for-profit under Belgian law, with over 150 member organisations operating in 27 countries. Its members include Access Point operators, platform providers, and technology companies that build and run the plumbing behind e-invoicing networks. The association has regional chapters in Germany, Italy, the Nordics, and the Middle East, each addressing the specific regulatory and market conditions of their area.
Since 2022, GENA has cooperated with OpenPeppol on a shared interoperability framework, working to align the interests of commercial service providers with the governance of the Peppol network. For service providers trying to keep pace with new mandates and technical requirements across multiple jurisdictions, GENA acts as a collective voice in regulatory consultations and standards development.
What is the DBNAlliance?
The DBNAlliance (Digital Business Networks Alliance) is a US-focused 501(c)(6) nonprofit that launched in January 2024. It grew out of a pilot programme run by the Business Payments Coalition, which was backed by the Federal Reserve as part of broader efforts to modernise B2B payments in the United States.
The alliance operates a 4-corner exchange network built on UBL 2.3 and AS4 transport - the same core standards used in Peppol, though with its own governance and certification programme. Certified providers on the network include Avalara (which has offered free US domestic e-invoicing since October 2025), Storecove, and Sovos, among others.
Because the United States has no federal VAT and therefore no government-driven e-invoicing mandate, adoption through the DBNAlliance is entirely industry-led. Businesses join for the efficiency gains - automated invoice delivery, structured data, and reduced processing costs - rather than to meet a regulatory requirement. The USA e-invoicing guide covers the current state of play in more detail.
What is CEN and what does TC 434 do?
CEN (Comite Europeen de Normalisation / European Committee for Standardisation) is the body responsible for developing voluntary technical standards across the European Union. Within CEN, Technical Committee 434 is the group specifically tasked with electronic invoicing. TC 434 developed the EN 16931 standard - the European Norm that defines the semantic data model for an electronic invoice - under a mandate from the European Commission tied to Directive 2014/55/EU.
The committee has around 25 active members drawn from national standardisation bodies across the EU. It first published EN 16931 in 2017, establishing the baseline that all EU member states must accept for public-sector invoicing. A revised version (EN 16931-1:2025) was approved in February 2026, updating the semantic model to address issues identified during eight years of real-world use.
TC 434 organises its work through several working groups: WG1 handles the semantic data model, WG3 manages syntax bindings (mapping the model to UBL and CII XML), WG5 deals with extensions that allow country-specific additions without breaking interoperability, and WG7 maintains the registry of code lists and identifiers. The standard they maintain is the single most influential piece of e-invoicing regulation in Europe, and it increasingly serves as a reference point for countries outside the EU as well.
What is FeRD?
FeRD (Forum elektronische Rechnung Deutschland) is the German association responsible for the ZuGFeRD hybrid invoice format. ZuGFeRD combines a human-readable PDF with embedded CII XML data, giving recipients both a visual document they can read and open in any PDF viewer and a structured data file their accounting software can process automatically.
ZuGFeRD is an EN 16931 Extension, meaning it conforms to the European standard while adding fields specific to German business requirements. FeRD works alongside KoSIT (the Coordination Office for IT Standards) on Germany's broader e-invoicing standards, including the XRechnung format used for B2G invoicing.
The hybrid approach has proven popular in Germany's B2B market, particularly among small and mid-sized businesses that want the benefits of structured e-invoicing without requiring every trading partner to have specialised software. A ZuGFeRD invoice can be emailed as a PDF attachment and processed manually by the recipient, or ingested automatically if their system supports CII XML extraction.
What is FNFE-MPE?
FNFE-MPE (Forum National de la Facture Electronique et des Marches Publics Electroniques) is the French association that manages Factur-X, the Franco-German hybrid invoice format. Factur-X is technically identical to ZuGFeRD - both wrap CII XML inside a PDF/A-3 container - but is maintained and promoted under separate branding for the French market.
FNFE-MPE plays an active role in France's e-invoicing policy discussions, coordinating with the DGFiP (Direction Generale des Finances Publiques) on the country's B2B e-invoicing mandate, currently set to begin its phased rollout in 2026. The association provides guidance to businesses preparing for the mandate and works to ensure that Factur-X remains aligned with both the EN 16931 standard and France's national requirements.
For businesses operating across France and Germany, the technical equivalence of Factur-X and ZuGFeRD means a single format works in both markets. The France e-invoicing guide has more on the mandate timeline and technical requirements.
What is AUSTRIAPRO?
AUSTRIAPRO is the Austrian association responsible for the ebInterface e-invoice format, which serves as Austria's national standard for B2G (business-to-government) invoicing. Since 2014, all suppliers to Austrian federal government entities have been required to submit invoices in ebInterface format through the USP (Unternehmensserviceportal) platform.
The association works with the Austrian Federal Ministry of Finance (BMF) and the Austrian Standards Institute to maintain and develop the format. ebInterface has gone through several versions, with each iteration adding support for new use cases while maintaining backward compatibility.
While ebInterface is specific to Austria, AUSTRIAPRO also participates in European standardisation efforts and supports the adoption of EN 16931 within Austria. For Austrian businesses that invoice the public sector, ebInterface remains the required format, though Peppol-based invoicing is gaining ground for cross-border transactions.
What is TIEKE?
TIEKE (Tietoyhteiskunnan kehittamiskeskus) is a Finnish nonprofit that supports businesses in adopting digital standards and processes, with e-invoicing as one of its long-standing focus areas. Finland was one of the earliest adopters of e-invoicing in Europe - the country's Finvoice standard dates back to 2003 - and TIEKE has been involved in promoting adoption since the early days.
TIEKE works alongside the Finnish Peppol Authority (Valtiokonttori, the State Treasury) to support Peppol adoption in Finland and provides training, documentation, and advisory services to businesses transitioning from paper or PDF invoicing to structured electronic formats.
Less well known internationally than OpenPeppol or CEN, TIEKE plays an important role in the Nordic e-invoicing ecosystem. Finland consistently ranks among the countries with the highest e-invoicing adoption rates in Europe, and much of that progress traces back to the groundwork laid by organisations like TIEKE in building awareness and practical capability within Finnish businesses.
