If you came for a self-employed invoice template, here’s the short answer. You can use a template to learn the structure. From 2026 you must issue the final invoice with Verifactu-compliant software or the free app. Below you’ll find the simplest checklist of what to include, when a simplified invoice is ok, and how to handle numbering. This guide is for any autónomo (self-employed person in Spain), freelancer, or micro-SME with no legal background.
Quick Q&A
Can I use Word or Excel? Use them to learn and draft. Do not use them to issue invoices from July 2027 as a new regulation comes into play.
Is there a free way to issue? Yes. The tax agency will provide a free app. If you want a more user-friendly flow, renn (also free) issues invoices with the required Verifactu QR and short verification line, and keeps numbering tidy.
Do I need e-invoicing? B2B e-invoicing is separate. This page is about basic invoices and Verifactu. B2B e-invoicing means sending invoices between businesses through an official electronic channel.

What every invoice must include in Spain (simple checklist)
- Invoice number and series - one sequence, no gaps.
- Date - when you issue the invoice.
- Your details - name or business name, address, NIF (Spanish tax ID), VAT number if you have one.
- Customer details - name and address, and tax ID if needed.
- Description - what you sold, in plain words.
- Amounts - base, VAT (value-added tax) if any, total to pay.
Helpful extras
- How to pay - IBAN or payment link.
- When to pay - due date.
- References - order or project name.
- Notes - short legal notes if needed.
Simplified invoice (factura simplificada): the easy rule
Use it for small sales and some retail settings. It needs fewer customer details. If your client needs full VAT support or you go over the small limits, issue a full invoice. When unsure, issue a full invoice.
Invoice numbering and series
Pick one format and stick to it all year. Examples of safe ideas: by year (2025-0001) or by channel (WEB-0001). Do not skip numbers. Do not edit old invoices. Start a fresh series when the year changes.
Verifactu: what changes in practice
Verifactu is Spain’s new rule that forces invoices to be created in certified software so they can’t be secretly changed. From 1 January 2026 companies must issue with compliant software. From 1 July 2026 freelancers must do the same. Invoices will carry a verification line and a QR code. You create, number, and store invoices inside the software. If you need to fix something, you issue a correction invoice (factura rectificativa). Read more.
Can I keep an Excel/Word template?
Yes, for drafts and branding. No, for issuing from 2026. Upload your logo and footer once in your software and save it as your default layout.
Bottom line
A self-employed invoice template is great to learn the structure. From 2026, issue the final legal invoice only with Verifactu-compliant software or the free app. Set your series, add your branding, and test one invoice now. You will avoid rework later and stay compliant.
