Is e-invoicing mandatory in Estonia?
For the public sector, yes, and increasingly for B2B. Suppliers to the Estonian public sector have had to send e-invoices since 2019. Under the Accounting Act, since 1 July 2025 any business registered as an e-invoice recipient in the commercial register can require its suppliers to send structured e-invoices.
Peppol (Pan-European Public Procurement On-Line) is the standard network for exchanging structured electronic invoices across Europe. Estonia was an early e-invoicing adopter and uses Peppol to connect its network of private e-invoicing service providers for cross-border exchange.
Estonian e-invoicing is governed by the Accounting Act (Raamatupidamise seadus). Suppliers to the public sector have had to send machine-readable e-invoices since 2019. From 1 July 2025, a buyer-choice regime applies to all accounting entities: any business registered as an e-invoice recipient in the commercial register can require its suppliers to send structured e-invoices in the European standard format.
By default, e-invoices must now follow the EN 16931 European standard. The legacy Estonian format, EVS 923 (e-arve), is still allowed when both parties agree. A full domestic B2B mandate is expected around 2027, so connecting to Peppol now keeps you compliant today and ready for what comes next.
Estonian e-invoices are exchanged as structured XML over the Peppol network. Invoicier generates and validates these formats for you.
On the Peppol network, Estonian businesses are addressed by a participant identifier built from their official registration numbers.
