E-Invoicing in Estonia

​In Estonia, electronic invoicing was introduced in April 2019 for business transactions with public institutions (B2G). Since then, public sector suppliers have been required to submit their invoices electronically. There is no central government system for the exchange of electronic invoices; instead, companies use various private service providers that enable the sending and receiving of e-invoices. July 1, 2025 Companies registered in the Business Register as e-invoice recipients can require their suppliers to issue electronic invoices. Furthermore, the Estonian government plans to 2027 to make electronic invoicing mandatory for all B2B transactions in order to increase efficiency and improve VAT collection.
