Verifactu responsible declaration

Fiscal version 1.0 · signed on 10 September 2026

Bouzon POS has its responsible declaration, signed by its producer. You can download it in full below.

Billing software in Spain is not registered or homologated in any government list — that procedure does not exist. The Spanish Tax Agency says so literally: «no se prevé ningún registro previo del producto SIF por parte de nadie». What the law requires is that the producer of the software declares, under its own responsibility, that the system complies: the declaración responsable of article 13 of Royal Decree 1007/2023, with the content and headings set by article 15 of Order HAC/1177/2024. If a vendor tells you their software is "approved by the tax authority", they are describing something that does not exist.

System: Bouzon TPV · fiscal version: 1.0 · producer: Pablo Bouzon (trading as Bouzon Digital) · signed on 10 de septiembre de 2026, in Benalmádena.

Full document: sections a) to l) of art. 15.1 plus the art. 15.2 annex. Drafted and signed in Spanish, the language of the legislation it answers to; no translation is authoritative.

Where else it lives

Article 13.2 of the Regulation requires the declaration to be available in writing and visibly within the software itself, for each of its versions, and to the customer at the time of acquisition. So it is in both places: published at this permanent address and inside the POS, at Settings → Invoicing → Verifactu, where any user can read it without leaving the program.

One declaration per version

The fiscal version is raised when something covered by the declaration changes — the record format, the hash, the chaining, the signature, the event log, the QR code or the fields of the SistemaInformatico block — and not for interface, pricing or reporting changes. Each version has its own declaration and previous ones are kept, as art. 13.3 requires. 1.0 is the first one, so there is no earlier declaration to consult yet.

What the venue has to do

This declaration covers the software and is signed by its producer. As the taxable person, you do not have to do anything with it beyond keeping it if your accountant asks.

  • You do not register the software anywhere. There is no such procedure.
  • You do not file form 036 to opt into VERI*FACTU. The option is tacit and is taken as made once records start being submitted. ⚠ And it lasts: art. 16.5 of the Regulation extends it at least to the end of the calendar year of the first effective submission.
  • Your only step is your own FNMT certificate, which you upload into the system; that is what signs and submits your records under your identity.

Current deadlines (RDL 15/2025) are January 2027 for companies and July 2027 for the self-employed. Product details at Bouzon POS; the producer's details are in the legal notice.
