E-invoicing mandate

E-invoicing in Croatia

A sourced summary of the structured e-invoicing program in Croatia. It is a starting point, not a compliance certificate or proof of delivery.

A generic EN 16931 or Peppol-style export does not by itself satisfy Croatia's CIUS, KPD classification, fiscalization and intermediary-delivery steps.

What this means for you

Croatia's Fiscalization 2.0 requires VAT-registered businesses to issue and receive domestic structured e-invoices from 1 January 2026. Non-VAT businesses receive from that date and issue from 1 January 2027. Issued line items require a six-digit KPD 2025 classification code.

What FreeBillGen can verify

For eligible saved invoices, FreeBillGen can prepare generic OASIS UBL and UN/CEFACT CII mappings and run its named internal checks. These mappings are not EN 16931, Factur-X, Peppol, national-CIUS or clearance-platform validation. FreeBillGen does not transmit them through a provider network.

The free Inbox can manually parse selected UBL/CII supplier files for review. Syntax recognition is not profile validation; manual upload is not a Peppol or government-network receiving endpoint and does not by itself satisfy a receive obligation. Open manual upload
