Exchange Summit Europe 2026 @ Berlin, Sept 30 – Oct 2

REGISTER HERE

The E-Invoicing Exchange Summit Europe returns to Berlin from 30 September to 2 October 2026, opening with a workshop day followed by a two-day conference. Under the banner “Mandatory E-Invoicing Accelerates Across Europe,” it brings together more than 1,000 finance, tax, and technology leaders from over 50 countries to confront the reality that e-invoicing has shifted from an efficiency tool to a strategic pillar of VAT compliance and digital government policy.
The programme is anchored in the practical fallout of ViDA and the revision of EN 16931. Workshop A delivers the 2026 research of the Politecnico di Milano’s International Observatory on E-Invoicing, while Workshop B dissects the EN 16931 overhaul — new data elements, business rules, syntax-binding changes, and the extension methodology in the ViDA era. Conference sessions span Peppol updates, DRR implementation trajectories, and actionable ViDA steps for VAT departments.
Country momentum is the connecting thread. With Belgium, France, Germany, and Poland already implementing mandates and Slovakia and Spain following shortly — plus the UK confirming an April 2029 mandate built on Peppol — sessions such as “E-Invoicing in the UK – From Roadmap to Delivery” and “Data quality in the Peppol network” give delegates concrete preparation roadmaps rather than theory.

An event that has outgrown the “why” question

For the organisers, the framing of the 2026 edition is deliberate. “Ten years ago, e-invoicing was discussed primarily as a way to improve efficiency. Today, it has become a strategic element of tax compliance and digital government policy. The debate has moved beyond whether companies need e-invoicing – the real challenge is how multinational organisations can keep pace with an increasingly fragmented regulatory landscape,” says Johannes von Mulert, Founder and Chairman of the E-Invoicing Exchange Summit.

That fragmentation is the summit’s central problem statement. Governments are the main drivers of the mandate wave, motivated by improved tax compliance, a reduced VAT gap, and better visibility into economic activity. As more countries adopt Continuous Transaction Controls (CTCs) and Peppol-based reporting, others follow — and the EU’s ViDA package, adopted in 2025, will introduce mandatory cross-border e-invoicing and digital reporting for intra-EU transactions from 2030, giving many governments cover to roll out domestic mandates simultaneously.

Day 1 (30 September): Workshops and the Icebreaker

The summit opens with a workshop day in Berlin, following registration and welcome coffee from 09:30.

Workshop A (10:30–13:30) — A Year of E-Invoicing: The 2026 Research Results of the International Observatory on E-Invoicing. Delivered by the Politecnico di Milano team (Riccardo Mangiaracina, Paola Olivares, Aida Cavalera, Asia Jane Leigh and Umberto Zanini), it analyses global developments, compares country approaches, and tackles open ViDA questions — combining institutional perspectives with real business experiences.
Workshop B (14:30–17:30) — Revision of EN 16931 – And How This Affects Your Business. Led by CEN TC434 experts Paul Simons (Convenor WG1), Dr. Lars Rölker-Denker and Svante Schubert (editor of the syntax bindings, WG3), the session walks through the revision’s three pillars: new and changed data elements and business rules, syntax-binding and codelist changes, the reworked extension methodology (core-conformant vs. non-conformant), the expected implementation timeline, and the impact on national rollouts and DRR-based e-reporting.
Icebreaker Reception (17:30–21:00) closes the day, where all participants and speakers collect badges and begin networking.

Days 2–3 (1–2 October): The Conference

The conference proper opens at 09:00 on 1 October with a welcome from Johannes von Mulert. Confirmed and advertised key topics include:

Figures, Data, Facts: the latest global e-invoicing developments and their significance for Europe
Potential E-Invoicing and DRR implementation trajectories under ViDA
Future-proofing compliance — how best-in-class companies ride the mandate wave
A global update on Peppol
Connected & automated business — more than just e-invoicing
Preparing for e-invoicing from finance, IT, and tax perspectives
Actionable steps and strategies under ViDA: what’s the big deal for VAT departments?

Two sessions are already drawing attention. Michael Walther (co-founder of The Invoicing Hub) will speak with Philip Helger on “Data quality in the Peppol network: Validation in AP and AR.” And with the UK mandate confirmed for April 2029, Ellen Leith (PPN CEO / UKeLab co-founder) will moderate the panel “E-Invoicing in the UK – From Roadmap to Delivery” with UKeLab members Didier Lombard, Liz Barclay and Phil Bailey.

Why it matters for VAT and tax leaders

For multinationals, the value proposition is squarely about managing complexity. With ViDA’s DRR on the horizon, EN 16931 in flux, and a patchwork of national go-live dates (France maintaining its start date, Poland proposing draft VAT amendments, Italy consulting on ViDA), the summit functions as a single point to benchmark readiness across jurisdictions and pressure-test compliance strategy against both regulators and peers.
