The best invoicing software in Spain: 7 real options, compared honestly
Searching for invoicing software in Spain from an English-speaking browser returns either global tools that ignore Spanish tax rules or Spanish lists with zero context for expats. This is the missing comparison: the 7 platforms that actually matter in Spain, what each one costs, and the compliance detail that will make or break them all in 2027 — VeriFactu. Full disclosure up front: FacturaOk is our product. Cards on the table.
The 2027 elephant in the room
From January 2027 (companies) and July 2027 (freelancers), Spanish invoices must be produced by software generating hash-chained, tamper-evident records with a QR code (Royal Decree 1007/2023 — «VeriFactu»). Any tool you pick today should already comply and publish its manufacturer's responsible declaration. Every option below claims compliance; verify the declaration before paying.
The quick table
| Software | Best for | Free tier | Paid from |
|---|---|---|---|
| FacturaOk | Freelancers & SMEs wanting compliance handled, UI in English/Spanish | 5 invoices/month, forever | €9.90/mo unlimited |
| AEAT free app | Absolute zero cost, 1-3 invoices/month | Unlimited invoices | — |
| Billin | Polished UI, Spanish-first | 30-day trial | €8-28/mo by client limits |
| Quipu | Accounting + taxes, not just invoicing | Trial | €8.50-29.50/mo |
| Holded | SMEs needing a full ERP | Trial | Higher, ERP pricing |
| Contasimple | Tight budgets, basic accounting | Limited free plan | €6.60-20/mo |
| FacturaDirecta | Deliberate minimalism | Limited free plan | Low-cost plans |
Notes an expat will care about
- English interfaces are rare. Most Spanish invoicing tools are Spanish-only. FacturaOk runs fully in English and Spanish; the AEAT app and most competitors do not.
- The AEAT's free app is genuinely free and compliant, but spartan: no simplified invoices (tickets), no logo, and — the real catch — no data export if you later migrate.
- IRPF retentions and reverse-charge EU invoices are where generic international tools (not listed here) silently fail. Whatever you choose, test both cases.
- Switching later is legal. VeriFactu's hash chain is per-system: a new platform starts its own chain, flagged as such to the tax agency. You're never locked in by the regulation — only by your tool's export options.
Our honest recommendation
Zero cost and minimal needs: the AEAT app — or FacturaOk's free Starter if you want your logo, tickets, mobile apps and an exit door. Invoicing seriously: FacturaOk Pro (€9.90/month, unlimited) or Billin if its client-based limits fit you. Full accounting: Quipu. Team ERP: Holded.

FAQ
Is there invoicing software in Spain with an English interface?
Few options. FacturaOk works fully in English and Spanish. Most Spanish competitors, and the AEAT's free app, are Spanish-only.
Is the Spanish tax agency's free invoicing app good enough?
For 1-3 full invoices a month, yes — it's compliant and unlimited. It has no simplified invoices, no logo, and no export if you ever want to leave.
Can I use QuickBooks, FreshBooks or other international tools in Spain?
Risky: Spanish requirements (IRPF retentions, exemption clauses, and above all VeriFactu's hash-chained records from 2027) are not implemented by most global tools. Check for a published responsible declaration before relying on one.
Am I locked into whatever software I choose?
Not by law: VeriFactu's chain is per-system and switching is expressly contemplated. Check the tool's export options though — that's the real lock-in.
