UBL 2.1 is required for B2G in Estonia. Estonia has mandatory B2G e-invoicing since July 2019 and introduced a "buyer's choice" model from July 2025 — buyers registered in the Commercial Register can demand e-invoices from any supplier, who must comply.
Buyer's choice model. From July 2025, buyers registered as e-invoice recipients in the Estonian Commercial Register can legally demand e-invoices from any supplier. The default format is EN 16931 unless otherwise agreed. The legacy Estonian e-arve (EVS 923) format is still accepted but declining. Exchange occurs via private operators (Billberry, E-arveldaja, Finbite, Telema, Unifiedpost) with no central government platform.
