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:

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

Industry Bodies [MEDIUM]

HGK (Hrvatska gospodarska komora): Croatian Chamber of Commerce — account codes for receivables [MEDIUM]
RRiF: Professional accounting guidance and chart publication [MEDIUM]
Ministry of Finance: Sets official accounting standards [HIGH]

5. Record Keeping Requirements [MEDIUM]

Retention Period [MEDIUM]

UNVERIFIED — needs confirmation from Croatian Accounting Law
Likely 5-10 years based on EU standards and neighboring country practices
RECOMMENDATION: Consult Croatian accounting advisor for exact retention periods per document type

Electronic Storage [MEDIUM]

Allowed: Yes, electronic storage permitted in Croatia [MEDIUM]
EU Compliance: Must follow EU standards for electronic archiving
Requirements:
- Original format preservation
- Integrity and authenticity guarantees
- Audit trail maintenance

6. Fiscalization 1.0 (B2C) [HIGH]

Real-Time Cash Register Fiscalization [HIGH]

Applies to: All B2C (end consumer) transactions [HIGH]
Requirement: Tax receipt (or electronic equivalent) must be transmitted to Croatian Tax Authorities in real-time [HIGH]
Effective: Existing requirement, continues alongside Fiscalization 2.0

Technical Requirements [MEDIUM]

Certified fiscal devices (cash registers)
Real-time connection to Tax Authority servers
Unique receipt identifier (JIR — Jedinstveni identifikator računa)

7. MVP Impact Assessment

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

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
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
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)
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)

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
Advanced IFRS Features [LOW PRIORITY]
- Full IFRS reporting for PIEs (Public Interest Entities)
- Consolidated financial statements
- Multi-entity accounting
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

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)
UBL 2.1 Generator
- Same engine can serve B2G and B2B
- EN 16931 validation library required
- Consider open-source UBL libraries (Java, PHP, Python)
Digital Certificates
- Qualified certificates required for invoice signing
- Croatian CA (Certification Authority) needed
- May require Croatian company registration
Language Localization
- Croatian language MANDATORY for:
  - Chart of accounts
  - Invoice templates
  - Tax reports
  - User interface (if targeting Croatian SMBs)

Risks

Mature Market: Croatia has had B2G e-invoicing since 2019 — competitors exist
Complexity: Dual system (1.0 + 2.0) adds overhead
EU Compliance: Stricter standards than Serbia/BiH
FINA Dependency: Single national platform — downtime = business stoppage

Competitive Advantage

EU Standards: Croatia's EN 16931 compliance means Bilko could expand to other EU markets more easily
First-Mover (Balkan SaaS): Few Balkan-region SaaS products support Croatian Fiscalization 2.0
Cross-Border: Croatian companies doing business in Serbia/BiH could use Bilko for all three markets

UNVERIFIED ITEMS — NEEDS LOCAL ADVISOR REVIEW

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