VeriFactu, introduced under Royal Decree 1007/2023 and updated by Royal Decree-Law 15/2025, mandates that all invoicing software used in Spain must guarantee the integrity, traceability and immutability of every invoice issued. The VeriFactu obligation applies from 1 January 2027 for taxpayers subject to Corporate Income Tax and from 1 July 2027 for self-employed under IRPF. SMARTeIS is a fully VeriFactu-ready, AEAT-certified Spain e-invoicing software with built-in chained hashing, electronic signing, QR code generation, and direct real-time submission to AEAT.

FacturaE is Spain’s official XML-based electronic invoice format, mandatory for B2G transactions via the FACe platform and accepted under the Crea y Crece B2B mandate. Beyond FacturaE, SMARTeIS supports every format Spain officially accepts under its decentralised CTC model – UBL, CII and EDIFACT – alongside Peppol BIS Billing and the EN 16931 European standard. This ensures first-time acceptance across AEAT, public buyers, and trading partners regardless of their format preference.

The Suministro Inmediato de Información (SII), mandatory in Spain since 2017 for businesses with annual turnover above €6 million, requires near real-time submission of invoice ledgers to AEAT within four days. SMARTeIS automatically generates SII-compliant XML packages, manages the 4-day reporting window, and synchronises invoice data with the Agencia Tributaria’s portal. Businesses already complying with SII are exempt from VeriFactu, and SMARTeIS handles both AEAT regimes seamlessly for groups with mixed entities.

SMARTeIS is architected with EU data sovereignty as a core principle. All Spain e-invoicing data is processed and stored exclusively within EU-based data centres, ensuring full compliance with GDPR, Spain’s LOPDGDD, the ePrivacy Directive, and NIS2 cybersecurity requirements. The platform includes encrypted data processing, audit trails, configurable retention policies, and undergoes regular third-party audits for ISO 27001 and SOC 2 Type II compliance.

Yes. SMARTeIS supports centralised AEAT-compliant management of multiple legal entities, each with its own Spanish NIF, VeriFactu and FacturaE validation profiles. For businesses also operating in France, Germany, Belgium, or Italy, the platform automatically applies the correct country-specific e-invoicing format and routing logic per entity, giving headquarters consolidated visibility while maintaining local compliance with each tax authority.

Yes. The Basque Country (TicketBAI) and Navarre operate their own regional e-invoicing regimes outside the standard AEAT framework. SMARTeIS includes pre-configured TicketBAI profiles for the three Basque provinces (Bizkaia, Gipuzkoa, Álava) and Navarre’s Foral invoicing regulations, ensuring businesses operating across mainland Spain and these autonomous regions can centralise their Spain e-invoicing while meeting every regional requirement.

Yes. SMARTeIS integrates seamlessly with your existing ERP infrastructure without requiring core system changes for VeriFactu or AEAT compliance. Pre-built connectors are available for SAP, Oracle, Microsoft Dynamics, Sage 200, A3 (Wolters Kluwer), Odoo, ContaSOL and other ERPs widely used in Spain. Your finance teams continue working in familiar ERP interfaces while SMARTeIS handles FacturaE conversion, VeriFactu signing, AEAT submission, and transmission to trading partners.

AEAT regulatory updates are included at no additional cost. SMARTeIS maintains a dedicated European Compliance Center that continuously monitors AEAT announcements, ministerial orders, VeriFactu specification updates, and ViDA directive developments. When Spain e-invoicing regulations change, the platform’s validation engines, format templates, and routing logic are updated automatically and deployed to all clients without downtime – keeping your solution compliant as Spain’s tax landscape evolves.

SMARTeIS includes a comprehensive Spain e-invoicing archive aligned with Spanish statutory requirements, four years for tax retention under the Ley General Tributaria, and six years for commercial documents under the Código de Comercio. Invoices are stored in their original FacturaE or UBL formats alongside AEAT submission responses, VeriFactu hashes, digital signatures, and full transmission logs. All archived documents are tamper-proof, fully searchable, and instantly retrievable for AEAT inspections.
