TicketBAI and Veri*factu*: Is your Shopify POS ready for the Spanish Tax Agency in 2026? (Spoiler: Yes, and it's free)

If you are a Finance or Operations Director at a retail company in Spain, you have a date marked in red on the calendar: January 2026 .

This marks the full implementation of the Veri*factu* regulation (Anti-Fraud Law) across Spain, following the lead of TicketBAI in the Basque Country. The regulations are clear: every receipt issued in-store must generate a QR code, have an unalterable digital fingerprint, and be sent to the Tax Agency in real time.

This is where the panic sets in. Many traditional (legacy) POS systems are asking for €5,000 to "update the software" to comply with the law. Or worse, they tell you that you have to replace all the cash registers.

If you use Shopify POS , I have great news: The problem is now solved thanks to Comply .

What happens if my POS system doesn't comply in 2026?

The penalties for using "dual-use software" or uncertified systems are severe. We're talking about fines of up to €50,000 per year. The Tax Agency wants complete traceability: it should be impossible to delete a sales receipt once it's been issued.

Many American or British Shopify agencies are unaware of this. They set up your POS system and leave you vulnerable to an inspection. At Migraciones.io , local taxation is the first step in any project.

Comply: The app that saves your business

Shopify, aware of the complexities of Spanish tax law, has promoted official solutions like the Comply app. It's not a workaround; it's a deep integration into the core of Shopify POS.

What exactly does Comply do?

• QR Code on the Ticket: When printing the receipt on your Star Micronics or Epson printer, Comply automatically injects the legal QR code required by Veri*factu*.
• Digital Fingerprint (Chaining): Cryptographically links each invoice to the previous one. If you try to delete one, the chain is broken and the system alerts you. 100% compliance.
• Sending to the Tax Office (SII / TBAI): Connects to the electronic headquarters of the AEAT or the provincial councils (Álava, Bizkaia, Gipuzkoa) and sends the XML of the invoice in milliseconds.

The best part: Your store staff doesn't have to do ANYTHING

The beauty of this solution is that it is invisible to the shop assistant.

Your employee continues using Shopify POS on the iPad just like always: scanning, processing payments, and hitting the "Print" button. Comply runs in the background . There's no need to open any extra programs or manually upload files at the end of the day. The Shopify user experience remains seamless.

Adaptation Costs: Legacy vs Shopify Plus

Frequently Asked Questions about Taxation and Shopify

Is Comply working for TicketBAI in the Basque Country yet?

Yes. The integration is ready to communicate with the regional tax authorities. If you have stores in Bilbao or San Sebastián, you can legally use Shopify POS today, issuing receipts with the required TBAI and QR codes.

And what about B2B Electronic Invoicing?

The Crea y Crece Law also mandates the issuance of electronic invoices between businesses (B2B). Shopify Plus, through integrations with ERPs (Business Central) or tools like Quaderno and Comply, can automatically generate the FacturaE format and send it through public exchange platforms (FACeB2B, etc.).

Can I use Comply if I don't have Shopify Plus?

Yes, the app is available for standard Shopify plans, but in high-volume environments (Retail with many stores), we recommend Plus to have access to the advanced features of POS Pro (staff management, multi-warehouse inventory) that usually go hand in hand with complex tax operations.
