- Estonia’s B2B e-invoicing rules took effect on July 1, 2025 and are based on “buyer’s choice,” not a universal mandate: a business registered in the Commercial Register as an e-invoice recipient can require suppliers to send structured e-invoices.
- The default standard is EN 16931 when the buyer requests an e-invoice, unless the parties agree on another format.
- Estonia does not require all companies to exchange e-invoices for all B2B transactions, and a proposed broader B2B mandate tied to VAT reporting has not been approved.
- The system is decentralized, allowing private e-invoicing providers, accounting software, ERP systems, and Peppol for domestic and cross-border exchange.
- B2G e-invoicing has been mandatory since 2019, and public entities remain registered recipients, so suppliers to Estonian public administrations must be able to issue e-invoices.
