Finland has no business-to-business e-invoicing mandate and no clearance system. It has something narrower and more useful: since 1 April 2020, a Finnish buyer can insist on a structured invoice, and Finvoice 3.0 and Peppol BIS Billing 3.0 both satisfy that. Send either through our certified gateway.
The short answer
No. Finland has no B2B mandate and no clearance system, so invoices are not cleared by a tax authority before they are sent. But since 1 April 2020, section 4 of the Act on Electronic Invoicing (241/2019) lets a Finnish business with turnover above €10,000 require a structured e-invoice from another business on request.
What the Act on Electronic Invoicing (241/2019) actually requires, who it binds, and which formats satisfy it
No Finnish business is obliged to send electronic invoices to another business. Section 4 of the Act on Electronic Invoicing (241/2019) does something different: it gives a buyer the right to ask for one. A contracting entity or a trader may request an invoice from another contracting entity or trader as a structured electronic invoice, and the supplier must provide it. That right has applied since 1 April 2020 — the Act came into force a year earlier, on 1 April 2019, with section 4 deferred.
"Trader" is defined in section 2 as a business whose turnover in the financial period exceeds €10,000, so very small suppliers sit outside it. Source: statute 241/2019 on Finlex, the Ministry of Justice's own legal database.
Section 3 of the same Act obliges public buyers to receive and process electronic invoices arising from public procurement contracts. Finland went further than the EU directive behind it and applied the obligation below the EU procurement thresholds as well.
In practice central government accepts nothing else. Finland's State Treasury states that "from April 1 2021, the state will only receive invoices in accordance with the European standard", and that it "will not receive invoices attached to an email, as this is not an electronic invoice". Source: State Treasury, Invoicing the state.
The Act does not name a format. Section 2 defines an electronic invoice as one issued, transmitted and received in a structured electronic form that allows automatic processing and complies with the European standard EN 16931. Any syntax meeting that definition qualifies.
The European Commission's Finland factsheet lists what is actually in use: Finvoice 3.0 and TEAPPSXML 3.0 as national formats where they comply with the European standard, Peppol BIS Billing 3.0, and the standard's own syntaxes UBL 2.1 and CII. Finance Finland, which publishes the Finnish standard, confirms the current schema is Finvoice 3.0.

Finland runs no clearance mandate. There is no government platform that has to approve or stamp an invoice before it reaches the buyer, and no real-time VAT reporting obligation attached to invoicing. The European Commission records Finland's VAT real-time reporting mandate as "NO" and states that "currently there is no real-time reporting system in Finland".
That makes Finland a post-audit country: invoices travel supplier to buyer through banks, operators or Peppol, and the tax authority looks afterwards. For how that compares with the countries introducing mandates, see our 2026 e-invoicing mandates tracker, which covers Germany, Belgium, Poland and the rest of the EU timetable.
One thing to watch: the European Commission records that Finland plans to begin preparations by 2028 for electronic invoicing on intra-EU transactions. No Finnish B2B mandate date has been set, and this page will say so until one is.
Finland's pioneering e-invoicing standard that revolutionized how Nordic businesses exchange financial documents.
Finvoice (verkkolasku in Finnish) was launched in 2003 by the Federation of Finnish Financial Services, making Finland one of the first countries to adopt standardized electronic invoicing. Today, over 80% of B2B invoices in Finland are sent electronically — a trend explored in our e-invoicing whitepapers.
The standard uses XML-based messaging and is supported by all major Finnish banks and e-invoicing operators. Finvoice addresses are based on the OVT code (Organisaatioiden Välinen Tiedonsiirto) derived from the Finnish Business ID (Y-tunnus).

Everything you need to know about Finnish electronic invoicing and verkkolasku
No. Finland has no B2B mandate and no clearance system, so invoices are not cleared by a tax authority before they are sent. But since 1 April 2020, section 4 of the Act on Electronic Invoicing (241/2019) lets a Finnish business with turnover above €10,000 require a structured e-invoice from another business on request.
Finvoice is Finland's national e-invoicing standard, known locally as "verkkolasku" (network invoice). Launched in 2003, it's an XML-based format that enables structured electronic invoice exchange between businesses through Finnish banks and certified operators. Over 80% of B2B invoices in Finland are now sent electronically via Finvoice.
OVT (Organisaatioiden Välinen Tiedonsiirto) is your unique Finvoice address derived from your Y-tunnus (Finnish Business ID). It follows the format 0037 + Y-tunnus without the hyphen (e.g., 003712345678). When you register with GoRoute.ai, we automatically generate your OVT code and register it with the TIEKE Finvoice address directory.
No format is mandatory by name. What Finnish law requires is a structured electronic invoice that complies with the European standard EN 16931: the Act on Electronic Invoicing (241/2019) defines an electronic invoice that way, and Finvoice 3.0 is one of the formats that satisfies it, alongside TEAPPSXML 3.0, Peppol BIS Billing 3.0, UBL 2.1 and CII. Public buyers must receive and process such invoices under section 3, and Finland's State Treasury accepts only European-standard e-invoices for central government.
With GoRoute.ai, Finvoice sending starts at €0.10-€0.30 per invoice, significantly cheaper than paper invoicing (€15-30 per invoice including processing). There are no setup fees, no monthly minimums, and receiving invoices is free. Compare this to traditional Finnish operators charging €50-200/month plus per-transaction fees.
GoRoute.ai connects to all major Finnish banks (Nordea, OP Financial Group, Danske Bank, Aktia, S-Pankki, Savings Banks Group) and operators (Maventa, Basware, Pagero, OpusCapita, Apix, Ropo Capital, Netvisor) through the Finvoice interoperability network. We automatically route invoices to whichever operator or bank handles your recipient.
Finvoice is a Finnish national standard for domestic invoicing. For international partners, GoRoute.ai provides seamless bridging to Peppol — the Pan-European e-invoicing network used in 40+ countries. We automatically convert your invoices between Finvoice and Peppol BIS 3.0 formats, enabling you to invoice EU customers and Nordic neighbors from a single platform.
You can look up Finnish e-invoicing addresses through TIEKE's official verkkolaskuosoite.fi directory, or use GoRoute.ai's built-in recipient lookup. Simply enter the company's Y-tunnus (Business ID) or name, and we'll find their Finvoice operator, intermediary code (välittäjätunnus), and e-invoice address automatically.
Finvoice 3.0 is the current version of the Finnish e-invoicing standard, aligned with the European EN16931 semantic model. GoRoute.ai fully supports Finvoice 3.0 and handles all format conversions automatically. We also maintain backward compatibility with Finvoice 2.x for recipients who haven't upgraded yet.
GoRoute.ai integrates with popular Finnish accounting systems including Netvisor, Procountor, Visma, Tikon, Heeros, and Fennoa, as well as international ERPs like SAP, Oracle, Microsoft Dynamics, and QuickBooks. We offer REST API, SFTP, and email-based invoice submission. Incoming invoices can be automatically forwarded to your accounting software.
Yes! GoRoute.ai enables companies from any country to send Finvoice-compliant invoices to Finnish businesses. We provide you with a virtual Finnish e-invoicing address and handle all format conversions. Your customers in Finland receive proper verkkolasku through their preferred bank or operator.
Most businesses are sending their first Finvoice within 24 hours of signing up. GoRoute.ai handles OVT code generation, TIEKE directory registration, operator connectivity, and format validation automatically. Compare this to traditional Finnish operators requiring weeks of paperwork and technical setup.
Absolutely. Finvoice is routed through Finland's banking infrastructure with bank-grade security. GoRoute.ai uses TLS 1.3 encryption, digital signatures on all documents, and maintains full audit trails. We comply with Finnish bookkeeping laws (kirjanpitolaki), GDPR, and Traficom security requirements for e-invoicing operators.
