The Spain new invoicing system (SIF) enters into force in 2027, making certified billing software and QR codes on every invoice mandatory for businesses and freelancers. Read our complete guide to SIF and VERIFACTU compliance.
Spain’s new Computerised Invoicing System (SIF) is mandatory for businesses and self-employed. Here’s what it means — without the technical jargon.
Any software you currently use to create invoices — dedicated billing software, ERP systems, POS terminals, Excel or even Word — must be replaced or upgraded with a certified system. The law is in force. The deadlines are fixed. The Spain new invoicing system affects every business and freelancer operating in Spain.
Spain’s Anti-Fraud Law (2021) and Royal Decree 1007/2023 set out the technical requirements of the Spain new invoicing system (SIF). For the business owner or freelancer, the practical impact is two things: your billing software must be certified, and every invoice must carry a QR code.
What does not change: how you work day to day. The Spain new invoicing system (SIF) is designed so that certified software generates the QR code and the XML record automatically in the background. You create invoices exactly as before.
Every invoice must include a QR code (30×40mm, top of document). Clients and the tax authority scan it to verify authenticity. Generated automatically.
Each invoice creates an XML «digital fingerprint» linked to the previous one — an unalterable chain guaranteeing the integrity of your invoicing history.
Your software provider must adapt their product. Most are already working on it. If they don’t, you have time to switch to a certified alternative.
Credit notes must specify the reason (R1–R5 codes). Your software handles the classification automatically. More order, better traceability.
«I make my invoices in Word / Excel — does this apply to me?» Yes. The regulation covers any programme that processes data to produce invoices, including Word and Excel. Only those writing every invoice completely by hand are exempt.
Once confirmed you’re in scope, you choose between the two compliant options the new Spain invoicing system permits:
