In the current Spanish regulatory landscape, many freelancers and small businesses confuse two major initiatives transforming financial operations: mandatory B2B electronic invoicing and the VeriFactu system. While both advance digitalization, they stem from different laws, target distinct goals, and carry separate technical requirements.
1. VeriFactu: Tax Anti-Fraud Oversight by AEAT
The VeriFactu system arises from Law 11/2021 on Anti-Fraud Measures and its technical framework in Royal Decree 1007/2023. Its core objective is eliminating double-use accounting software and ensuring billing records cannot be altered or deleted.
- Scope: Applies to all transactions, both B2B (business-to-business) and B2C (business-to-consumer).
- Requirements: Chained log registers (hash), QR codes printed on invoices, and optional or mandated real-time transmission to the Spanish Tax Agency (AEAT).
- Official Deadlines: The compliance deadline for incorporated companies is January 1, 2027, while the mandatory deadline for freelancers and micro-businesses is July 1, 2027. Read more in our guide on VeriFactu 2027 deadlines.
2. B2B Electronic Invoicing: Payment Transparency
In contrast, mandatory B2B electronic invoicing originates from Law 18/2022 (the "Crea y Crece" Law), overseen by the Ministry of Economic Affairs.
- Scope: Strictly transactions between businesses and professionals (B2B). Invoicing to end consumers (B2C) is excluded.
- Objective: Combating commercial delinquency and late payments by tracking mandatory invoice milestones (issued, received, accepted, and paid).
- Format: Mandates structured electronic data formats (such as Facturae or UBL) exchanged via certified private platforms or the public solution. Learn more in our electronic invoicing guide for freelancers.

Technical Integration and Software Migration
Complying with both regulations does not mean doubling your accounting workload when using the right setup. Developers and businesses with bespoke setups are already deploying a direct API VeriFactu or implementing a dedicated pasarela VeriFactu para software.
If you currently invoice with legacy desktop packages or generic cloud tools, transitioning is straightforward. Options exist to importar Factusol a VeriFactu, importar Sage 50, importar Holded, or execute a fast importar Excel a VeriFactu workflow to unify structured billing and verifiable records under one centralized integración ERP VeriFactu.
To navigate these requirements effortlessly, platforms like Fakturia.es deliver cloud-based invoicing natively tailored to VeriFactu and the Spanish Anti-Fraud Law, keeping your business fully compliant on autopilot.
