Is e-invoicing mandatory in Finland?
For the public sector, yes. Under the e-Invoicing Act 241/2019, central government has required EN 16931 e-invoices since April 2019 and all public bodies since April 2020. There is no general B2B mandate, but any buyer with annual turnover over EUR 10,000 has the legal right to demand e-invoices from its suppliers.
Peppol (Pan-European Public Procurement On-Line) is the standard network for exchanging structured electronic invoices across Europe. Finland is one of the most mature e-invoicing markets in the world, with more than 90 percent of its roughly 325 million yearly invoices already electronic. The State Treasury (Valtiokonttori) serves as the Finnish Peppol Authority.
Public-sector e-invoicing is governed by the e-Invoicing Act 241/2019: central government bodies have been required to receive and process EN 16931 compliant e-invoices since 1 April 2019, and all public contracting authorities, including municipalities, since 1 April 2020. The public sector is also rolling out Peppol for e-ordering and other procurement messages.
For B2B there is no general mandate, but the same Act gives any buyer with annual turnover over EUR 10,000 the right to demand EN 16931 compliant e-invoices from its suppliers, so in practice structured e-invoicing is the expected way of doing business in Finland. The common formats are Finvoice 3.0, TEAPPSXML 3.0, and Peppol BIS Billing 3.0, all aligned with the European standard.
Finnish e-invoices are exchanged as structured XML, domestically and over the Peppol network. Invoicier generates and validates these formats for you.
