In the Spanish tax landscape, digitalization is advancing by leaps and bounds. Two terms that cause confusion among freelancers and SMEs are "B2B electronic invoice" and "VeriFactu". Although they sound similar and both affect invoicing, they respond to completely different regulations and objectives. Understanding their differences is crucial to comply with the law and avoid penalties.
What is the B2B Electronic Invoice (Crea y Crece Law)?
The mandatory B2B (Business-to-Business) electronic invoice stems from the Crea y Crece Law. Its main goal is to combat late payments in commercial transactions between companies and professionals.
- Who it affects: All transactions between companies and/or freelancers (sole traders).
- What it requires: That invoices are issued and received in a structured electronic format (like Facturae) that allows for automatic processing. It also requires reporting on the invoice status (accepted, paid).
- The objective: Not direct tax control, but to improve the traceability of payments and reduce collection times. As of the current date (September 2026), this obligation is already in force for all companies and freelancers in their B2B operations.
What is the VeriFactu System (Anti-Fraud Law)?
VeriFactu, on the other hand, is an invoice verification system arising from Law 11/2021 on measures to prevent and combat tax fraud. Its goal is to ensure the integrity, conservation, and traceability of invoicing records.
- Who it affects: Virtually all business owners and professionals, in both B2B and B2C (with final consumers) transactions. You can learn more in our complete guide to VeriFactu for freelancers in Spain.
- What it requires: The use of invoicing software that meets certain technical requirements: generating a record for each invoice, including a QR code and a unique identifier, and ensuring that records cannot be altered.
- Key Deadlines: The obligation to use VeriFactu-compliant software will be effective on January 1, 2027, for corporations and on July 1, 2027, for everyone else, including freelancers and micro-SMEs.
Fundamental Differences: B2B vs. VeriFactu
To be clear, here are the key differences:
* Regulation: The B2B electronic invoice is governed by the Crea y Crece Law, while VeriFactu is based on the Anti-Fraud Law.
* Scope: The electronic invoice is only for B2B operations. VeriFactu applies to all invoicing (B2B and B2C).
* Objective: The former aims to combat late payments. The latter, to fight tax fraud.
* Focus: The Crea y Crece Law regulates the format and communication of the invoice. The Anti-Fraud Law regulates the software used to issue it.
Important: They are not mutually exclusive, but complementary. Starting in 2027, an invoice issued to another company must comply with both regulations: it must be a B2B electronic invoice and also have been generated with VeriFactu-compliant invoicing software.
Preparing Your Systems: Integration and Migration
Adapting to this dual regulation requires technological planning. VeriFactu ERP integration will be essential for companies already using management systems. Developers are providing a VeriFactu API or a VeriFactu gateway for software that allows connecting existing tools.
If you use programs like Factusol, Sage 50, or Holded, it's vital to check how they will adapt and plan the transition. Searches on how to import Factusol to VeriFactu or how to import Sage 50 to a compatible system will multiply. Even those wondering how to import Excel to VeriFactu must know that migrating to certified software will be necessary, as spreadsheets will not meet the inalterability requirements.

In short, being proactive is key. Solutions like Fakturia.es are already prepared to comply with the Anti-Fraud Law and the VeriFactu system, ensuring a simple and secure transition for your business.
