What's new?​

The E-Invoicing guide for Poland gained a new section describing the KSeF VAT exemption tax groups E, E2, and E3.

  • Sweden left beta — the Swedish country solution is now officially released.
  • The EFR as HTTPS Server section was reworked: the HTTPS server certificate and the client CA certificate can now be uploaded via API, password-protected certificates are supported, and the server certificate can also be provided via an environment variable.

What this means for our users?​

  • Poland — integrators handling VAT-exempt sales can look up exactly which exemption group to send for KSeF instead of deducing it from the schema.
  • Sweden — the documentation no longer carries a beta disclaimer; what you read is the officially supported solution.
  • HTTPS certificates — rolling out certificates to EFR installations no longer requires file-system access; the documented API upload covers server and client CA certificates, including password-protected ones.
