Invoice App for Finland

An invoicing app for Finland must inherently support Finnish legal and tax requirements to ensure smooth operations. All Business-to-Government (B2G) transactions have mandated e-invoicing since April 2020, requiring compliance with the European standard EN 16931. Furthermore, businesses with an annual turnover exceeding €10,000 have the right to request e-invoices from their suppliers. Essential invoice fields include the date of issue, a unique sequential number, and the VAT identification numbers for both the seller and, if applicable, the purchaser. The standard VAT rate in Finland is 25.5% (effective September 1, 2024), with reduced rates of 14% (changing to 13.5% in January 2026) and 10% for specific goods and services. Invoices must be archived electronically for at least six years, maintaining authenticity, integrity, and readability.

Effective e-invoicing and robust language support are crucial for businesses operating in Finland's digital landscape. The primary accepted e-invoicing formats are Finvoice 3.0, TEAPPSXML 3.0, and Peppol BIS Billing 3.0, all of which align with the European standard EN 16931. The Peppol network is particularly significant, facilitating secure and efficient cross-border and B2G e-invoicing, with its usage steadily increasing. While invoices can be issued in any language the customer understands, the Finnish Tax Administration may request a translation during an audit. Many invoicing solutions offer the flexibility to generate invoices in Finnish, Swedish, and English, accommodating diverse clientele and international business needs.

Seamless integration and automation features are vital for streamlining invoicing workflows for Finnish businesses. Look for apps that offer integration with Finnish banks, enabling direct payment processing and reconciliation. Emerging solutions, such as the partnership between Orbyt and Siirto, are even allowing direct Finvoice e-invoice delivery into consumers' mobile banking apps, simplifying payment for end-users. Automation of recurring invoices is a key feature, reducing manual effort for regular billing cycles. For overdue payments, an app should facilitate automated payment reminders. The first payment reminder can typically be sent after two weeks from the original due date, and subsequent reminders can follow after at least 14 days from the previous one. Overdue interest can begin accruing immediately after the due date if specified, or 30 days after the invoice was sent otherwise.
