Choosing good invoicing software is one of the decisions that saves you the most time and headaches as a freelancer or small business. The right program turns issuing invoices, tracking expenses and filing taxes into something automatic, instead of an error-prone spreadsheet. And since the entry into force of Spain's Anti-Fraud Law and the VeriFactu system from the Tax Agency, it is no longer optional: your software must generate unalterable, chained and verifiable invoices. In this guide we compare the best invoicing software of 2026 for Spain with real pricing, free plans, pros, cons and which type of business each one fits best.
The range is wide: from ultra-simple tools designed for the freelancer who only invoices, to business management suites that combine invoicing, accounting, CRM and inventory. The decision should not be based on price alone: what really matters is VeriFactu compliance, ease of use, bank reconciliation, tax filing (VAT, income tax, forms 303 and 130) and access for your accountant. Let's break it down.

Before subscribing, look at five factors. First, VeriFactu compliance: in 2026 it's non-negotiable that your program is certified and generates unalterable invoices; check that the provider states it explicitly. Second, the functional scope: if you only need to issue invoices and keep an expense log, a simple tool like FacturaDirecta or Contasimple is enough; if you want accounting, inventory and CRM in one place, Holded or Sage 50 save you from juggling several tools. Third, bank reconciliation and automatic ticket/invoice reading, which save hours every month. Fourth, tax filing (forms 303, 130, 390, 347) and the ability to give your accountant access. And fifth, the real price based on your volume and number of users, not the headline price.
For most SMBs and freelancers with some volume, Holded is the most complete bet because it unifies invoicing, accounting, CRM and inventory in a single suite adapted to VeriFactu. If you're a freelancer who just wants to invoice simply and cheaply, FacturaDirecta or Contasimple offer the best simplicity-to-price ratio. And if you sell digital products online to customers in several countries, Quaderno automates international VAT like no other.
Holded starts around 9 EUR/mo (14-day trial). It's the most complete option for SMBs and freelancers who want to centralize invoicing, accounting, CRM, projects and inventory in a single cloud tool, already adapted to VeriFactu.
FacturaDirecta starts free / from around 10 EUR/mo. It's the favorite of freelancers and small businesses who want to issue professional invoices in seconds without complications, with legal compliance and a very clean dashboard.
Quaderno starts around 49 USD/mo (7-day trial). It's the reference tool for digital businesses selling software, courses or info-products online that need to correctly calculate and report VAT across multiple countries automatically.
Contasimple starts free / from around 6 EUR/mo. It's the cheapest option for the freelancer just starting out who wants to invoice, track expenses and prepare taxes with a real free plan and a very tight paid price.
Sage 50 sits from around 30 EUR/mo (demo on request). It's the reference option for SMBs with professional accounting and for those working hand in hand with their accountant, with a powerful accounting module widely adopted by Spanish accounting firms.
VeriFactu is the system of the Spanish Tax Agency, derived from the Anti-Fraud Law (Law 11/2021) and its regulation, that requires invoicing software to generate unalterable and chained invoices, with a verification code (hash) and a QR code, optionally sent to the tax authority in real time. The goal is to prevent the deletion or manipulation of invoices. In practice this means that, from its entry into force, your program must be certified and responsibly declare compliance with the regulation; using Excel or a non-adapted program is no longer legal for issuing invoices.
All the programs in this comparison are adapted or in the process of adapting to VeriFactu, so that point shouldn't be the deciding factor: simply check that the provider states it and keep the software updated. Beyond compliance, think about your business's full ecosystem: host your website and store on reliable hosting, protect access to your tax data with a password manager, and combine invoicing with a good CRM for SMBs to keep the commercial relationship and billing connected. If you also do email marketing, integrate your list with your invoicing to automate payment reminders and renewals from your email marketing platform.
