fiskaltrust's Solutions for Spain
In Spain, fiscal regulations are driven by regional mandates like TicketBAI (Basque Country) and national initiatives like VERI*FACTU from the AEAT. These require point-of-sale (POS) systems to generate, sign, and submit transaction data electronically to tax authorities in near real-time.
Key Requirements in Spain:
- TicketBAI (Basque Country): Obligates the issuance of digitally signed invoices sent directly to the regional tax agency (Hacienda Foral).
- VERI*FACTU (National): Requires software to report VAT-related transactions in real time to the national tax agency (AEAT) and maintain detailed logs.
- Invoice Certification: POS software must be certified, and logs must include tamper-evident elements like cryptographic chaining.
- Business Scope: Applies to both cash and invoice-based transactions, especially relevant for SMEs and service providers.
Key Benefits for Developers
- Single API for all Spain-specific mandates: Avoids duplicated effort for each region.
- Vendor-neutral architecture: Compatible with certified devices and signature providers.
- Automated compliance updates: fiskaltrust maintains alignment with AEAT and local requirements.
- Modular approach: Easily support hybrid use cases (e.g., cash + invoice, cloud + on-prem).
Integration with the fiskaltrust Middleware API
POS developers integrate once using fiskaltrust’s POS-API, which abstracts all compliance logic, including:
- Digital signature creation (compatible with IvaServicio and other RT-Devices)
- TicketBAI payload construction and submission
- VERI*FACTU export formats and audit trails
- Receipt creation and distribution in digital or printed formats
Compliance Automation
Once implemented, fiskaltrust.Middleware handles:
- Data ingestion and validation from the POS
- Hashing and chaining for compliance with TicketBAI
- Generation of XML or structured invoice formats required by authorities
- Communication with tax agencies for real-time or deferred reporting

- Middleware is updated without disrupting your POS logic.

- fiskaltrust collaborates in working groups to align early with upcoming mandates.
