    E-invoicing is a statutory obligation in Finland for public sector invoices and is rapidly becoming more common in the private sector. In this article, we'll go through what an e-invoice means, what Act 241/2019 requires, and how a small business can correctly implement e-invoicing.

    What is an e-invoice?

    An e-invoice is an electronic invoice sent in a structured format, which is transferred directly from the sender's system to the recipient's system without manual processing.

    An e-invoice is not the same as an email invoice or a PDF invoice. The key difference:

    • E-invoice: structured data (e.g., Finvoice, TEAPPSXML, Peppol BIS), machine-readable
    • PDF invoice: an image of an invoice, requires manual processing or OCR reading
    • Email invoice: PDF as an email attachment – does not meet e-invoice requirements

    Act 241/2019: what does it require?

    The Act on Electronic Invoicing for Contracting Entities and Business Operators (241/2019) came into force on 1.4.2020. It is based on EU Directive 2014/55/EU.

    The key content of the Act:

    • Invoices sent to the public sector (state, municipalities, joint municipal authorities) must be e-invoices
    • The recipient must be able to receive e-invoices compliant with the EU standard (EN 16931)
    • A business operator has the right to request an e-invoice from another business operator
    • The Act does not yet mandate all private sector invoicing to be e-invoices, but the direction of development is clear

    EN 16931 – EU invoicing standard

    EN 16931 is the common EU standard for the data content of an e-invoice. It defines what information an e-invoice must contain and in what format.

    In practice, EN 16931 means that a Finnish e-invoice is compatible with a German, French, or Spanish system – as long as both comply with the same standard.

    In Finland, the most common e-invoice formats are Finvoice (used by banks) and TEAPPSXML (used by operators). Both are EN 16931 compliant.

    Implementation checklist for small businesses

    1. Choose invoicing software that supports e-invoicing (e.g., Eemel Invoicing)
    2. Obtain an e-invoicing address (OVT ID or Peppol identifier)
    3. Enter into an agreement with an e-invoicing operator (or use the invoicing software's built-in operator)
    4. Update your invoice template to include all statutory information
    5. Test sending an e-invoice to a few customers
    6. Communicate your e-invoice address to customers and update it in TIEKE's e-invoice address registry

    Common mistakes in e-invoicing implementation

    • E-invoice address not registered: customer cannot find your address
    • Mandatory information missing from invoice template: invoice recipient will reject it
    • VAT identifier not correctly marked: in EU trade, an incorrect identifier causes problems
    • PDF invoice is mistaken for an e-invoice: a PDF in an email is not an e-invoice
    • Operator agreement missing: invoice will not move through the operator network

    Practical example: a renovation company and public procurement

    A five-person renovation company received its first public sector contract from a municipality. The invoice had to be sent as an e-invoice – otherwise, it would not have been accepted.

    The company started using Eemel Invoicing, which has e-invoicing built-in:

    1. An e-invoice address was automatically created during implementation
    2. The invoice was sent directly to the municipality's system in Finvoice format
    3. Payment was received in 7 days (previously 21 days with paper invoices)

    Now the company sends all its invoices as e-invoices – even to private customers' online banks.

    Frequently asked questions

    Is e-invoicing mandatory for all businesses?

    Not yet. Act 241/2019 mandates the use of e-invoices for public sector invoices. In the private sector, e-invoicing is still voluntary, but a business operator has the right to request it.

    What is OVT ID?

    OVT ID is a Finnish e-invoice address. It consists of the country code 0037 and the company's Business ID without a hyphen.

    Can a small business send e-invoices?

    Yes. Sending e-invoices is possible, for example, through Eemel Invoicing without separate agreements with operators.

    What is Peppol?

    Peppol is an international e-invoicing network that enables cross-border invoicing in the EU. In Finland, Peppol is becoming more common, especially in public sector invoicing.

    How does an e-invoice differ from an online invoice?

    An online invoice is an electronic invoice for consumers, sent to online banking. An e-invoice is a structured invoice between businesses that is transferred directly to the financial management system.
