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.
