VeriFactu, SII, TicketBAI and Facturae: they are not the same thing

Why do four names collapse into the same search?

Because all four touch the invoice and the tax authority. They do not share a rule, a territory or what you have to send.

VeriFactu and SII: if I already report, does it apply to me?

In practice, not as an extra duty. The SII already sends invoice information down another pipe. The RRSIF is not there to duplicate that.

• SII = Immediate Supply of Information. It is a regime for sending billing records to the AEAT, older and different.
• SII taxpayers are generally outside the VeriFactu duty. They already report another way.
• Do not turn “I am in the SII” into a shortcut if you are not. Joining the SII has its own thresholds and rules. The advisory firm confirms that, not a headline.
• It is not the other way around either: entering VeriFactu does not put you in the SII. They are different doors.
• The [2027 dates](/blog/verifactu-2027-fechas-sociedades-autonomos) are not SII deadlines. Do not paste them onto the calendar of someone who already supplies in real time.

Are TicketBAI and Navarra “the Basque VeriFactu”?

No. That sentence sells training and software. In foral territory the foral system applies, not the state RRSIF under another name.

• Basque Country: TicketBAI. It is the foral invoicing duty with software and sending to the Basque treasuries.
• Navarra: its own foral invoicing system. That is not VeriFactu either.
• If your registered office is in common territory and you have an establishment in foral territory, do not copy one date onto both. Ask for advice.
• A Basque QR is not the RRSIF QR. A foral hash does not take you out of the state SIF, or the other way around.
• Vacly does not sell TicketBAI or a foral mode. The [Fiscal module](/producto/fiscal) organises common-territory taxes. It does not file with any treasury.

Does Facturae spare me VeriFactu?

No. Facturae solves the file format. VeriFactu solves how the system records and, if required, remits. They can coexist.

• Facturae is an XML schema for electronic invoices. Anyone who bills the public sector uses it a lot.
• Having the XML does not prove a SIF. It does not replace the chained hash, the RRSIF QR or the manufacturer’s responsible declaration. That is in [requirements](/blog/requisitos-verifactu-sif-qr-hash).
• Vacly Facturación can read a Facturae file. That is reading a document, not meeting the RRSIF.
• “Mandatory electronic invoicing” and “VeriFactu” have been mixed in headlines. They are not the same law and not the same date.
• If your client asks for Facturae, that is a format requirement. If your territory asks for a SIF, that is a system requirement. Charge each one by its name.

How do I pick the channel without inventing a rule?

Territory first. Then the channel (SII or other). Then the system. The reverse order produces double purchases.

• Common territory and not in the SII: look at VeriFactu and the [2027 dates](/blog/verifactu-2027-fechas-sociedades-autonomos).
• You are in the SII: in general this duty is not added on. Confirm it; do not leave the SII because of a post.
• Basque Country or Navarra: TicketBAI or the foral system. Do not use this article for a foral enrolment.
• The [Fiscal calendar](/producto/fiscal/calendario-fiscal) and [forms](/producto/fiscal/modelos-aeat) follow the VAT and withholding period. They do not pick a territory for you.
• The law provides for sanctions if you fail the channel that does apply. We do not put amounts. Electronic office and advisory firm.

What does Fiscal do with this soup of names?

It orders the period. It does not change your regime. It does not enrol you in the SII or take you out of TicketBAI.

• [Taxes](/producto/fiscal/impuestos), [forms](/producto/fiscal/modelos-aeat) and the [calendar](/producto/fiscal/calendario-fiscal) live in the [Fiscal module](/producto/fiscal). €12.90/month VAT incl. 15-day trial.
• We do not file with the AEAT. We do not remit VeriFactu records. We do not certify the program.
• Facturación is the inbox. It is not SII, not TicketBAI, and not “official” Facturae just because it can read the XML.
• Next practical step: [how to prepare the company for 2027](/blog/como-preparar-empresa-verifactu-2027). The short definition is still in [what it is](/blog/que-es-verifactu).
• If you operate in two territories, this article does not draw the map. Your adviser does.
