Finland has one of the highest e-invoicing rates in Europe. Approximately 90% of invoices are sent digitally. Finvoice is the Finnish invoice standard that has been widely used for years. Through Peppol, Finnish businesses are also reachable internationally.

By way of indication: Finland processes approximately 325 million e-invoices per year. The national register contains approximately 370.000 businesses. There are approximately 13.000 Peppol end-users and approximately 780.000 Peppol transactions per year.

The Finnish PASR (approved 2025-09-09 by Valtiokonttori) includes the following key points:

• Identifier: only the OVT code (0216) is permitted. Changes in the Y-tunnus (Finnish business registration number) require an OVT update.
• Verification: Service Providers must verify End Users in the register of the Finnish Patent and Registration Office (ytj.fi).
• ACL (Access and Capability Lookup): the public sector must be registered in the ACL register (central and local government, municipalities, churches, state enterprises).
• SLA: changes to identifier or Service Provider must be processed within 3 business days.
• ISO 27001: recommended but not mandatory.

Finvoice is the Finnish invoice standard and is used both via the banking network and via Peppol. For international invoicing, Peppol BIS 3.0 is the recommended route. The eConnect PSB supports both routes.

Invoicing Finnish businesses or government bodies works seamlessly via Peppol in most cases. The eConnect PSB routes invoices to Finnish recipients via the Peppol network and automatically adapts the format.
