Verifactu Best FAQ

What is Verifactu and why is compliance important?

Verifactu is the technical standard and regulatory framework established by the Spanish Tax Agency (AEAT) for the issuance, storage, and reporting of electronic invoices. Compliance is legally mandatory for most business-to-business (B2B) and business-to-government (B2G) transactions in Spain. Using non-compliant software can result in significant financial penalties, the inability to deduct VAT on expenses, and administrative complications during tax audits. Verifactu Best helps businesses avoid these risks by directing them to verified solutions.

Is Verifactu Best itself a billing software?

No, Verifactu Best is not a billing or invoicing software application. It is a specialized online directory and discovery platform. Its function is to catalog, categorize, and provide detailed information about third-party software products that are compatible with the Verifactu standard. Users visit Verifactu Best to research, compare, and find the right tool, but they must subscribe to or purchase the chosen software directly from its respective provider.

How does Verifactu Best verify software compatibility?

While the exact verification process is managed by the platform administrators, listings typically indicate compatibility through official badges like "✅ Compatible con Verifactu" or references to a "Declaración Responsable" from the software vendor. This suggests the directory team vets vendors based on their public declarations, technical specifications, and adherence to AEAT's published requirements, creating a curated list trusted by the business community.

Can I find free software on Verifactu Best?

Yes, the directory includes a "Gratis" (Free) category, indicating that some listed software solutions offer free tiers or trial versions. However, it is crucial to examine the details of each profile, as the free version may have limitations on features, the number of invoices, or user access. The platform allows users to filter for these options to find solutions that fit a limited budget while still meeting core compliance needs.
