Croatia — eRačun & HR-FISK

Croatia — eRačun and Fiscalization (Fiskalizacija)

Last Updated: 2026-02-20 Confidence Level: HIGH (Croatia is EU member with well-documented regulations)

Overview

Croatia, as an EU member state, implements a comprehensive e-invoicing and fiscalization system. Two parallel systems operate as of January 1, 2026:

  1. Fiscalization 1.0 — B2C (end consumer) transactions with real-time cash register fiscalization
  2. Fiscalization 2.0 — B2B and B2G electronic invoicing with mandatory use of the eRačun platform

Technical Requirements [MEDIUM]

7. MVP Impact Assessment

MVP-CRITICAL (Must Have for Legal Operation in Croatia)

  1. eRačun B2B Integration (Fiscalization 2.0) [HIGHEST PRIORITY]

    • UBL 2.1 or CII XML invoice generation
    • EN 16931 standard compliance
    • Real-time transmission to eRačun platform API
    • FINA platform integration
    • WITHOUT THIS: B2B invoicing is ILLEGAL in Croatia as of Jan 1, 2026

  2. PDV (VAT) Calculation [HIGH PRIORITY]

    • Support for 25% / 13% / 5% / 0% rates
    • Automatic rate selection based on product/service type
    • VAT report generation for monthly filing

  3. Croatian Chart of Accounts [HIGH PRIORITY]

    • RRiF-compliant account structure
    • Croatian language support for account names
    • IFRS-aligned for publicly traded clients (if targeting them)

  4. eRačun B2G Integration (if targeting public sector clients) [HIGH PRIORITY]

    • Servis eRačun za državu platform API
    • UBL 2.1 format (recommended)
    • EN 16931 compliance
    • Mandatory since 2019 — mature system

FUTURE (v2 or Later)

  1. Fiscalization 1.0 (B2C Cash Registers) [MEDIUM PRIORITY]

    • Only needed if Bilko targets retail/POS segment
    • Most B2B SaaS accounting software does NOT need this
    • Fiscal device certification required

  2. Advanced IFRS Features [LOW PRIORITY]

    • Full IFRS reporting for PIEs (Public Interest Entities)
    • Consolidated financial statements
    • Multi-entity accounting

  3. Multi-Currency Support [LOW PRIORITY]

    • Croatia uses Euro (€) since January 1, 2023 [HIGH]
    • Initial MVP: Euro only
    • Foreign currency: Phase 2

Implementation Notes for Bilko

Critical Path for Croatia

  1. eRačun API Integration

    • Priority #1 — B2B invoicing is MANDATORY since Jan 1, 2026
    • Study FINA eRačun API documentation
    • Sandbox testing environment available
    • FINA Documentation: www.fina.hr (Croatian language)

  2. UBL 2.1 Generator

    • Same engine can serve B2G and B2B
    • EN 16931 validation library required
    • Consider open-source UBL libraries (Java, PHP, Python)

  3. Digital Certificates

    • Qualified certificates required for invoice signing
    • Croatian CA (Certification Authority) needed
    • May require Croatian company registration

  4. Language Localization

    • Croatian language MANDATORY for:
      • Chart of accounts
      • Invoice templates
      • Tax reports
      • User interface (if targeting Croatian SMBs)

Risks

Competitive Advantage

UNVERIFIED ITEMS — NEEDS LOCAL ADVISOR REVIEW

  1. Exact record retention period per document type: Likely 5-10 years, needs confirmation
  2. Non-VAT registered taxpayer e-invoicing delay: Confirmed Jan 1, 2027 — verify this is still valid
  3. FINA API technical specifications: Requires registration and Croatian company status?
  4. Digital certificate requirements: Type, issuing CA, cost
  5. Penalties for non-compliance: Fine amounts for missing/late B2B e-invoices
