Mandate Overview

The mandate

Estonia has been a Peppol pioneer since 2017 and now operates one of the most digitally mature invoicing regimes in Europe. B2G has been mandatory since 2019, requiring all public-sector suppliers to issue Peppol BIS 3.0 invoices through accredited Access Points. From July 1, 2025 any registered buyer can require its supplier to deliver structured e-invoices, effectively flipping the B2B regime to mandatory on the buyer's request under the amended Accounting Act.

FAQ

Common questions

Is B2B e-invoicing mandatory in Estonia?

Since July 1, 2025 any buyer registered as an e-invoice recipient in the Estonian Business Register can require its supplier to issue a structured e-invoice. This is functionally a mandate on the buyer's request. Full unconditional B2B mandatory e-invoicing is under consultation for 2027.

What format is required?

Peppol BIS 3.0 routed through accredited Access Points. The Estonian CIUS EVS 923:2024 layers Estonian Business Register and Statistics Estonia codes on top of EN 16931.
