Spain is moving toward mandatory B2B e-invoicing, with the proposed deadline expected in October 2027. While the legislation is still in draft, businesses operating in Spain are already navigating a multi-layered compliance landscape.
With Global E-invoicing Compliance, we are building out Spain support so your business can meet the upcoming requirements without adding new portals or separate integrations.
Spain's e-invoicing framework has evolved over more than a decade, and not every obligation is at the same stage yet. Some requirements are already in force, while others are still planned or in draft. Besides the upcoming mandate affecting B2B e-invoicing, we also have:
B2G e-invoicing: Public sector e-invoicing via FACE using the Facturae format has been mandatory since 2015 and remains in place.
SII reporting: The SII system already applies to large taxpayers and requires near-real-time VAT reporting.
Verifactu: This anti-fraud invoicing-software requirement is a separate obligation and is expected to apply from 2027.
Other regional requirements: Additional regional obligations may still apply depending on where a business operates.
Managing Spain's overlapping mandates (different formats, platforms, and reporting obligations) creates real overhead for internal teams. GEC is designed to handle that complexity centrally:
Multi-format support: We cover the full range of EN16931-compliant formats required in Spain, so invoices reach their destination correctly regardless of which platform your trading partner uses.
E-signature handling: Digital signatures might be included in scope for B2B e-invoicing. ecosio is ready to apply them automatically where required for platform-to-platform exchange.
Unified flows for B2B and B2G e-invoicing: Whether you are invoicing government entities via FACE or exchanging B2B invoices across platforms, everything runs through a single integration.
