E-Invoicing 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. A full B2B mandate is expected by 2027. The country uses a decentralized operator model with no central government platform.
Mandate Status
| Phase | Status | Scope |
|---|---|---|
| B2G | Live (Jul 2019) | All public sector suppliers |
| Buyer's choice | Live (Jul 2025) | Registered buyers can demand e-invoices from any supplier |
| Full B2B mandate | 2027 | Expected — legislation being drafted |

Implementation Notes
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.
