Build once, deploy everywhere. fiskaltrust empowers POS developers with powerful open-source middleware, modular APIs and expert-led onboarding to ensure seamless fiscalization compliance across Europe.

fiskaltrust’s Middleware offers a robust, flexible, and cost-effective solution for businesses seeking compliance with diverse fiscal regulations across Europe. Its standardized interface, multi-platform support, and open-source transparency make sure that businesses can focus on their main tasks while ensuring legal compliance, thereby providing peace of mind and operational efficiency.

fiskaltrust’s solutions for Belgium

Belgium requires POS systems to meet the fiscal rules defined by the Federal Public Service Finance, SPF Finances. Merchants in the hospitality sector must use certified systems that secure sales data and link each transaction to a fiscal device. The system is known as the SCE or FDM, also called the black box. It ensures the creation of traceable records that support tax audits and protect data integrity.

Key requirements in Belgium

  • Individual Recording Obligation. Each transaction must be recorded and linked to the certified fiscal device.
  • Receipt Issuance Obligation. A registered receipt must be provided with all legally required elements.
  • Certified Device Obligation. Merchants in the hospitality sector must use a certified POS system with an approved FDM or SCE.
  • Secure Storage. Fiscal data must be stored in a tamper resistant way and be available for audit.

Key Benefits for Developers

  • Standardised API for clear and predictable integration.
  • Support for certified Belgian fiscal devices without vendor lock in.
  • Stable compliance with SCE and FDM rules without changes to the POS logic.
  • Automatic updates that follow new rules from SPF Finances.

Integration with the fiskaltrust Middleware API

Developers integrate one API that manages signing, interaction with the fiscal device and receipt creation. This removes the need to create custom logic for each type of certified hardware.

  • Local and cloud deployments are supported.
  • Multiple FDM and SCE models are handled through one integration.
  • The middleware aligns POS transactions with the Belgian fiscal record format.

Compliance Automation

The middleware validates the data, applies the Belgian fiscal rules and creates receipts with all required fields including VAT information, signatures and identifiers.

  • Fiscal data is stored in a way that is ready for audit by SPF Finances.

Continuous EU-Wide Compliance

fiskaltrust monitors updates from SPF Finances and implements changes in the middleware so developers do not need to modify their POS systems.

  • Support for new device types is added as required.
  • Updates are rolled out centrally with minimal disruption to merchants.
  • Systems remain compliant during regulatory changes.

Stable API. Open source. Audit-proof receipts. No vendor lock-in.
