Verifactu is Spain’s set of requirements for invoicing software, under Royal Decree 1007/2023: each invoice record is chained to the one before it, carries a QR code, and cannot be altered once issued. For an accounting firm the work is making sure every client’s invoicing can meet it.
Three overlapping changes reach a Spanish accounting firm’s clients. Verifactu (the RSIF regulation, from the 2021 anti-fraud law) sets what invoicing software must do: produce a tamper-evident record of every invoice, with a hash linking it to the previous one, a QR code the recipient can check, and either real-time submission to the tax agency or stricter record-keeping. The Crea y Crece law brings mandatory structured B2B e-invoicing between businesses. And the EU’s VAT in the Digital Age (ViDA) package moves cross-border B2B invoicing towards structured e-invoices and digital reporting. The Basque territories already run TicketBAI, and large taxpayers already report through the SII.
None of this is a job for a language model to do. The compliant record has to come from invoicing software that meets the regulation, deterministically, every time. Where AI earns its place is in everything around that record: finding out which of two hundred clients are on software that will not comply, reading the inbound invoices that still arrive as PDFs, and catching the structured invoice that is valid in form and wrong in substance.

Verifactu is the name for Spain’s requirements on invoicing software, set by Royal Decree 1007/2023 under the 2021 anti-fraud law. Software must produce an unalterable record of each invoice, chained to the previous one by a hash, print a QR code the customer can check with the tax agency, and either send records to the agency as invoices are issued or meet stricter storage rules. It applies to companies and self-employed people who use invoicing software.
The start dates have been postponed more than once, so check the current dates on the AEAT website rather than relying on any third-party page, including this one. What does not change with the dates is the work: identify which clients use software that will comply, move the ones issuing invoices from spreadsheets onto something that will, and test the new invoices before the deadline rather than after it.
No. Verifactu governs how invoicing software records and reports invoices to the tax agency. Mandatory B2B e-invoicing, under the Crea y Crece law, governs the format invoices are exchanged in between businesses. At EU level, the VAT in the Digital Age package addresses structured e-invoicing and digital reporting for cross-border trade. A client can be affected by all three, which is why we track them separately per client.
No, and a supplier claiming so should worry you. The compliant record must come from invoicing software built to the regulation, behaving deterministically. AI helps around it: auditing which clients are ready, reading invoices that still arrive as PDFs and catching substantive errors in structured ones. Whether a client is compliant is the firm’s and the client’s determination.
