What is Verifactu and does it affect me?
Verifactu is Spain's new mandatory electronic invoicing system. Starting July 2027, all invoices must be generated with certified software including QR codes and hash chains. k-factu is already compliant from day one.
Do I need to do anything about Verifactu now?
If you use k-factu, no. It's already built in. What you should avoid is using non-compliant software — since July 2025 it's illegal to distribute it in Spain. k-factu has you covered.
Can I use k-factu in English?
Yes. k-factu works in 5 languages. Perfect for expat freelancers in Spain who need to invoice in English while complying with Spanish tax law.
How does the tax report feature work?
k-factu calculates quarterly IVA (Modelo 303) and IRPF (Modelo 130) from your real data. We mark it as 'for review with your accountant'. We never submit anything to the tax authority without your approval.
Can I try it for free?
Yes. The Free tier gives you up to 5 invoices per month and client management, forever, no credit card needed. When you need more, the Autonomo plan is EUR 9.99/month.
What happens to my data if I cancel?
They're yours. You can always download everything. And Spanish law requires invoice records to be kept for 4 years, so we never delete them.
