E-Invoicing in Finland

Finland has one of the most mature e-invoicing ecosystems in Europe. Since 2020, it is mandatory for B2G operations in transactions with the Public Administration. In the B2B environment, electronic invoicing is widely used in commercial relationships, even if there is no law that requires it.

In addition, many companies have already made the transition and they ask their partners to receive structured electronic invoices. Therefore, if your business or company operates in Finland, let's see what you should do. Keep reading!

Features of mandatory electronic invoicing in Finland (B2B)

There is no law for B2B operations. However, eInvoices in B2B are a common practice among companies and are usually interchanged through operator networks and PEPPOL.


Model: decentralized. There is no centralized state entity or platform. Finnish companies usually connect to an operator that complies with standardized formats and ships mostly through the Peppol network.

Formats: Finvoice3.0 (XML), TEAPPSXML 3.0 (XML), national XML formats widely used in public and private sector exchanges. The PEPPOL BIS Billing 3.0 format is also common.

Note: the three formats are used in practice since both the national formats (Finvoice 3.0, TEAPPSXML 3.0) and PEPPOL BIS Billing 3.0 meet the European standard IN 16931.

Archiving: 7 years.

eSignature: not mandatory.


B2G e-invoicing in Finland

The central government and most public entities have been requiring e-invoices for years. Since 2021, the central government has only accepted e-invoices in accordance with EN 16931.

In April 2024, the Finnish State Treasury announced that invoices sent to the Central Government must use PEPPOL Advanced Ordering. This could indicate that in the future it will be the option adopted.

Do I need to adapt my invoicing system to operate in Finland?

For all that we have said so far, it is highly recommended to have an electronic invoicing system to operate with Finnish partners. Whether you operate with Finnish public entities, or with other companies, since many partners expect structured electronic invoices (not just PDFs).
