The 5 Best Invoicing Apps for Freelancers in Spain in 2026
Invoicing from Word or Excel is on its way out in Spain: the Verifactu system requires invoices to be issued with software that records them and reports them to Hacienda, the Spanish tax authority. The five apps in this list are already compliant, but they have little in common: some only invoice, others handle the whole bookkeeping, and others are built for people who work on the road. This guide compares the 5 best invoicing apps for freelancers in Spain in 2026.
Verifactu-compliant invoicing software you can run from your phone
Invoicing apps for freelancers with invoices and quotes, tracking of payments and expenses, receipt scanning, quarterly VAT (IVA) and income tax (IRPF) calculation, bank connections and compliance with the tax agency's Verifactu system.

Frequently asked questions
Which is the best invoicing app for freelancers in Spain?
If you only need to issue invoices and track payments, TS Facturas is the most straightforward. If you also want your quarterly taxes calculated and everything shared with your accountant (gestoría), Quipu. Holded is the most complete, but also the one with the most features you probably will not use as a freelancer without employees.
What is Verifactu and why do I need compliant software?
Verifactu is the Spanish tax agency's system that requires invoices to be issued with software that generates a tamper-proof record of each one and can send it to Hacienda. The rollout timeline has been changed several times; check the current date for your case on the AEAT website. All five apps in this list state that they comply.
Are there free invoicing apps that comply with Verifactu?
Some offer free plans capped by the number of invoices per month. All the apps in this list are paid, with prices starting at around ten euros a month. The tax agency itself has announced a free invoicing application for small taxpayers.
Can I issue invoices from my phone only?
Yes, all of them let you create and send invoices from the app. The difference is in everything else: in Quipu and Anfix the app is a companion and the heavy lifting happens on the web; in TS Facturas and STEL Order the app covers almost all day-to-day use.
