Brussels, 1 July 2026 – Within the WE BUILD consortium, one of the large-scale pilots selected by the European Commission for the EU Digital Identity Wallet, e-invoicing is one of thirteen use cases now being developed in practice. The European Business Wallet Peppol connection is getting its first concrete test environment, which matters for any Peppol Service Provider looking ahead to the coming years.
What is the WE BUILD consortium?
WE BUILD, short for Wallet Ecosystem for Business and payments Use cases on Identification, Legal representation and Data sharing, was officially launched on 3 September 2025 at a General Assembly in Amsterdam. More than 180 organisations from 26 countries are involved, coordinated by the Dutch Chamber of Commerce (KVK), the Dutch Ministry of Economic Affairs and Sweden’s Bolagsverket. The consortium is developing thirteen use cases across the Business, Supply Chain and Payments domains to test the EU Digital Identity Wallet and the European Business Wallet in practice.
E-invoicing falls under the Supply Chain domain and is defined as the structured, machine-readable exchange of invoice data between suppliers and buyers, as set out in EU legislation. According to WE BUILD, the EU Digital Identity Wallet and the European Business Wallet should make e-invoicing practically scalable by providing a consistent, secure and verifiable trust framework for identity, authentication and authorisation across the invoicing chain.
Why this matters for Peppol Service Providers
Today, identity verification in e-invoicing still largely relies on manual checks and separate platforms. Authentication and authorisation mechanisms are not yet fully standardised, and cross-border interoperability remains limited. A European Business Wallet carrying a verified attribute, such as a validated Peppol participant ID, could allow a Peppol Service Provider to initiate an SMP lookup based on verified rather than manually entered identification data. That could reduce fraud-prone steps in the invoicing chain and strengthen the reliability of cross-border Peppol transactions.
Exactly how this connection will be shaped still needs to be worked out within WE BUILD. The Peppol Conference in Brussels, held on 16 and 17 June 2026, was a concrete moment where this integration between wallet technology and Peppol routing was on the agenda. Peppol.nu is following this development and will report once concrete technical arrangements are in place.
Part of a broader programme
E-invoicing is one of thirteen use cases WE BUILD is developing across its three domains. In the Business domain, use cases include setting up a company branch abroad, digitally proving authority to act on behalf of a business, and access to the Once-Only Technical System (OOTS) for exchanging official documents between public authorities. In the Payments domain, the consortium is working on corporate payments and bank onboarding. This overlap matters: a European Business Wallet once verified for company registration or bank onboarding could, in principle, reuse the same trusted identity attribute when setting up a Peppol connection, rather than each process requiring its own separate verification.
What this means for your organisation
For businesses already using Peppol-based e-invoicing, nothing changes in day-to-day practice in the short term. The WE BUILD use case is an exploration, not an obligation. Still, it is a signal: the European Business Wallet and Peppol infrastructure are moving closer together, and organisations investing now in a mature Peppol implementation are building a foundation aligned with this broader European direction.
