pretix 2026.1.0 is now available for installation via pip. The new Docker images will appear on Docker Hub over the next few hours. All customers of pretix Hosted are already using the new version and do not need to take any action.

E-invoicing for Italy

Italy was Europe's first country to implement mandatory e-invoicing for all transactions, including B2C purchases. All invoices must be created in the "FatturaPA" XML format and must be transmitted through the government's Sistema di Interscambio (SDI) platform.

We have added a new plugin that allows to create invoices in FatturaPA format and submit them to SDI automatically, utilizing capabilities of our new partner Invopop. Similarly to our recent Peppol support, this is currently only available on pretix Hosted and we charge €0.20 per successfully transmitted invoice.
