From 1 October 2026, the merger of four Visma entities dedicated to Nordic e-invoicing is formally active. InExchange (Sweden, founded 2008), Maventa (Finland, 2007), mySupply (Denmark, 2001) and efacto (over 25 years of activity across the Nordic countries) now operate under the single InExchange brand, led by Allan Freiheit. The combined entity claims the title of Europe’s largest Peppol operator, according to the official InExchange announcement of 25 September 2026.
From Announcement to Effective Merger
Visma had been preparing this consolidation for several months. Back in June 2026, we covered the original announcement: four brands built through successive acquisitions — each with its own customer base, Peppol certifications, and APIs — were to be brought together under a single umbrella. Maventa alone was processing more than 12 million documents per month and counted over 300 integrated ERP partners (InExchange.com). In August 2026, OWS, a Finnish Peppol and EDI services provider, joined Maventa ahead of its integration into the combined entity at the October deadline.
The InExchange brand has been retained as the single trading name. The stated objective: pool artificial intelligence investments, harmonise country-by-country regulatory coverage, and deliver a unified platform for SMEs, large enterprises and ERP partner publishers.
What Changes in Practice for Businesses
For existing Maventa or mySupply customers, InExchange’s message is unambiguous: no immediate changes to contracts, access credentials or account contacts. However, a merger of this scale typically triggers, within 12 to 18 months, a rationalisation of product lines and APIs. IT leaders renewing contracts over the coming months should verify portability terms and document their current flows: Peppol access points in use, message formats, and monthly volumes.
For ERP teams relying on these Peppol access points, the consolidation creates a single point of contact for Nordic coverage and parts of continental Europe. The symmetric risk is real: with one dominant actor on the Nordic Peppol network, alternatives in the event of service failure or price increases become scarcer. Procurement and IT leaders negotiating a renewal should include exit clauses in their contracts.
For SMEs yet to start their e-invoicing migration, the emergence of this consolidated player accelerates connector standardisation. That is good news on the technical front. Commercially, consolidation means fewer independent local operators to negotiate with, and increased reliance on a single supplier.
What to Watch Next
InExchange has communicated no migration dates or API changes at this stage. The next expected announcements will cover the unified product roadmap and any timeline for converging customer portals.
The regulatory backdrop adds urgency. The ViDA directive makes e-invoicing mandatory for all B2B cross-border transactions within the EU: the first cross-border mandates are expected for 2028, ahead of a full rollout by 2030. Businesses across the Nordics and Europe that use Maventa, mySupply or efacto as a Peppol access point should therefore confirm now that their operator falls within the merged perimeter, and plan for any required technical migrations ahead of regulatory deadlines.
