Belgium joins Sweden and Norway as top Peppol partner for Finland
Peppol transactions between Belgium and Finland have surged since Belgium's e-invoicing mandate took effect, making Belgium one of Finland's most common cross-border e-invoicing partners alongside Sweden and Norway.
Peppol Day Finland 2026 revealed that Belgium has rapidly become one of Finland’s top e-invoicing partners following Belgium’s e-invoicing mandate. The surge demonstrates how legislation can drive cross-border digital trade, though collaboration and industry adoption also play key roles.
Transactions between Belgium and Finland have skyrocketed since Belgium introduced its e-invoicing mandate. Belgium has now joined Sweden and Norway as one of the most common countries with which Finnish companies exchange electronic business documents.
The shift emerged during Peppol Day Finland 2026, held on 21 April at Finlandia Hall in Helsinki. The conference brought together Peppol Authorities from several countries, industry experts, and companies to discuss how Peppol enables more efficient cross-border trade. During audience discussion, speakers noted that Belgium’s mandate had clearly affected Finland’s Peppol statistics. New data arriving days after the conference confirmed the effect was substantial.
Legislation as a driver
The Belgium case demonstrates how regulatory action can accelerate e-invoicing adoption. Serge Libert, Project Manager at the Peppol Authority of Belgium (BOSA), shared Belgium’s e-invoicing journey at the conference. However, legislation is not the only path. Finland’s experience shows that collaboration and industry adoption also drive growth.
Cross-border collaboration unlocks potential
A Japan-Finland e-invoicing initiative began with an accidental request from the Finnish Ministry of Social Affairs and Health to a Japanese company. What started as a mistake became an opportunity to explore cross-border e-invoicing possibilities. The work led OpenPeppol to extend the PINT model to cover Europe, making e-invoicing possible regardless of national borders.
Hiroyuki Kato, Director of the Digital Agency and Cabinet Secretariat in Japan, hosted a panel discussion where Japanese companies operating in Finland shared their experiences adopting Peppol e-invoicing.
Ismo Tiittanen, Strategy Director at NCC Finland Ltd, argued that Peppol adoption requires industry-wide collaboration. Entire industries benefit when ordering, logistics, and invoicing processes are digitalised, he explained.

Untapped potential remains
Finland describes itself as a logistical island, bordered by sea to the south and west, wilderness to the north, and a closed border to the east. This geography challenges supply chains, but also motivates optimisation of cross-border trade.
The Peppol Authority of Finland challenged other Peppol Authorities to compare their transaction volumes with their countries’ export and import figures. In Finland’s case, this comparison reveals clear untapped potential, particularly with Germany and Nordic neighbours. If countries embrace interoperability through Peppol, the benefits of efficient global trade are already available to be realised.
The conference was organised in partnership with the Confederation of Finnish Industries (EK) and the Finnish Patent and Registration Office.
