The problem

Spanish businesses face two overlapping but distinct invoicing mandates that are frequently confused. Implementing the wrong technical requirements for VeriFactu or missing the Crea y Crece B2B deadlines leads to heavy non-compliance penalties, reaching up to EUR 50,000 for users and EUR 150,000 for developers.

What it does

• Identifies whether a business falls under VeriFactu, TicketBAI, SII, or the Basque/Navarra foral regimes.
• Validates software compliance against Real Decreto 1007/2023 requirements including SHA-256 hash chaining and QR code generation.
• Outlines the specific technical field structures for high-level and cancellation invoice records (registros de facturación).
• Maps the multi-phase Crea y Crece B2B e-invoicing rollout starting in late 2027.
• Generates vendor-specific questionnaires to verify the mandatory "declaración responsable" for invoicing software.

Frameworks & tools

Spanish AEAT specifications, Real Decreto 1007/2023 (RRSIF), Orden HAC/1177/2024, EN 16931 semantic model, and UBL syntax for the SPFE platform.

Why this beats prompting it yourself

Standard LLMs often reference outdated 2026 deadlines. This skill uses the corrected 2027/2028 timeline established by Real Decreto-ley 15/2025. It enforces the critical distinction between software certification (VeriFactu) and structured exchange (Crea y Crece) which generic prompts often blur.

Use cases

• Determine if an existing ERP or SaaS needs a "declaración responsable" to stay legal in Spain.
• Design the database schema for Spanish-compliant hash-chained invoice logs.
• Advise a Spanish "autónomo" on when they must switch to structured B2B e-invoices.
• Assess whether to adopt the real-time VERI*FACTU mode to reduce local data retention burdens.

Known limitations

Does not replace a professional tax advisor or legal counsel. Ministerial orders for Crea y Crece are based on the latest June 2026 drafts and require final BOE publication confirmation.
