fiskaltrust's solutions for fiscalization compliance in the European Union
Across the EU, fiscal compliance laws vary by country, but all aim to ensure secure, tamper-proof transaction recording and transparent reporting to reduce VAT fraud. fiskaltrust helps developers navigate this complexity by offering a unified Middleware API that adapts to national rules while providing a consistent developer experience.
Key Challenges Across the EU:
- Country-specific fiscal regulations and certification procedures
- Varied requirements for receipt formats, signing devices, and audits
- Rapid legislative change driven by EU VAT GAP reduction goals
- High integration and maintenance cost across multiple jurisdictions
Key Benefits for Developers
- Stable, versioned API: Same endpoints across countries, including /order, /pay, /sign, /issue, /journal, etc.
- Open source foundation: Code transparency and no vendor lock-in.
- Plug-in architecture: Connect fiscal devices, signature units, receipt formats, and payment terminals modularly.
- Future-proof updates: Country-specific rules are centrally maintained and updated automatically.
- Cross-border readiness: Extend your POS system into new EU markets without re-engineering your stack.
Integration with the fiskaltrust Middleware API
Developers integrate once with fiskaltrust’s POS-API to manage all fiscal interactions, from transaction capture to audit-proof storage. The Middleware handles signature creation, receipt generation, and compliance with national standards.
- Local: Runs on Windows, Linux, MacOS, Android (foreground service or kiosk).
- Cloud: Hosted in national Azure data centres for compliance and scalability.
- Hybrid: POS logic on device, signature and reporting in cloud.
- Supports various signature creation units (hardware/cloud)
- Compatible with different receipt formats and delivery methods (PDF, ESC/POS, QR code, SMS, e-mail)
- Integrates with existing ERP and POS solutions with minimal changes
Compliance Automation
Once integrated, fiskaltrust handles the complete lifecycle:
- Capture: POS sends data via REST/gRPC
- Validate and Sign: Middleware applies local fiscal rules
- Store: Secure, revision-safe archive for up to 10+ years
- Generate: Create receipts in required formats
- Deliver: Paper, digital, URL, or third-party app
- Report: Produce audit exports and lifecycle logs
Continuous EU-Wide Compliance
fiskaltrust is actively involved in national working groups and fiscalization initiatives across the EU. As new laws are enacted, fiskaltrust updates its Middleware to reflect these changes—so developers do not need to rewrite their systems for every regulation.
- Middleware is updated centrally
- Country logic is decoupled from your POS code
- All updates are backward compatible and version-controlled
- Developers receive audit-proof receipts without needing to master local tax laws
Stable API. Open source. Audit-proof receipts. No vendor lock-in.
