As of June 2026: B2G e-invoicing is mandatory (central government since 2019, all public bodies since April 2020). There is no general B2B mandate, but under the Act on Electronic Invoicing (241/2019) any business above €10,000 turnover may require EN 16931 e-invoices from its suppliers. Confirm current rules with the State Treasury (Valtiokonttori).
Finland made structured e-invoicing mandatory for central government from April 2019 and extended it to all public contracting authorities, including municipalities, from April 2020 — invoices must comply with the EU standard EN 16931. There is no blanket business-to-business mandate, but Finland's Act on Electronic Invoicing (Laki hankintayksiköiden ja elinkeinonharjoittajien sähköisestä laskutuksesta, 241/2019) gives buyers real leverage: any business with annual turnover above €10,000 has the right to require an EN 16931-compliant e-invoice (verkkolasku) from its supplier. In practice this makes B2B e-invoicing widespread even without a universal mandate. Common formats include Finvoice, TEAPPSXML, and Peppol BIS 3.0.
Because any Finnish business above €10,000 turnover can demand an EN 16931 e-invoice, the practical question is whether you can produce one on request. Invotify Pro exports Peppol BIS 3.0 and UBL 2.1, both aligned with EN 16931, so you can meet a buyer's request or invoice a public authority without changing tools. You generate the structured file in Invotify and route it over the Peppol network or your e-invoicing operator. Invotify produces the invoice; delivery is via your operator. E-invoicing is a Pro feature.
There is no universal B2B mandate, but it's close in practice. Under the Act on Electronic Invoicing (241/2019), any business with turnover above €10,000 can require an EN 16931-compliant e-invoice from its suppliers. So while you aren't forced to e-invoice everyone, a customer can compel you to send a structured e-invoice. B2G e-invoicing is fully mandatory. Confirm the details with the State Treasury (Valtiokonttori).
Finland's e-invoicing law lets any business above €10,000 annual turnover insist that its suppliers send EN 16931-compliant e-invoices instead of paper or PDF. It shifts the choice to the buyer, which is why structured e-invoicing is so common in Finnish B2B even without a general mandate. Invotify Pro exports EN 16931-aligned formats so you can comply when a buyer exercises this right.
When e-invoicing applies, invoices must comply with EN 16931. Common Finnish formats are Finvoice and TEAPPSXML, with Peppol BIS 3.0 increasingly used, especially cross-border. Invotify Pro exports Peppol BIS 3.0 and UBL 2.1 — the standards-based, EN 16931-aligned formats — which your e-invoicing operator can route into the Finnish network.
Invotify Pro generates structured Peppol BIS 3.0 and UBL 2.1 invoices that satisfy EN 16931, whether you're invoicing a public authority or responding to a buyer's €10,000 right. You export the file from Invotify and send it through your Peppol access point or operator. The e-invoice export is part of the Pro plan.
