Best Free Invoicing Software in Spain (2026 Comparison)

Searching for “free invoicing software” is the first thing any new freelancer in Spain does. It makes sense: you do not want to pay 20 EUR a month for a tool when you are not yet sure how much you will be invoicing. The problem is that “free” in software usually means “free with an asterisk,” and that asterisk matters a lot.

This comparison covers every real free option available in Spain in 2026. No sponsored rankings, no fluff, with verifiable data.

The real landscape of “free”

In the Spanish invoicing market, only three programs offer a permanent free plan:

Software	Free invoices	Time limit	Expenses	OCR	API
Frihet	10/month	No limit	Yes	Yes	Yes
Alegra	10/month	No limit	Yes	Yes	No
Contasimple	12/year	No limit	Yes	No	No

The rest of the market — Holded, Quipu, Anfix, Billin, Sage — does not have a free plan. They offer trial periods of 7 to 30 days, which is not the same thing.

Then there is the AEAT’s invoicing tool (Spain’s tax authority), which is 100% free but with significant limitations. We cover that too.

Frihet: 10 invoices/month with everything included

Frihet offers the most complete free plan in the Spanish market. 10 invoices per month with no time limit. It is not a disguised trial: it is a real plan that includes the same features as paid plans, with a volume cap. The same limit as Alegra, but with API, webhooks, and integrations included.

What the free plan includes:

• 10 invoices and quotes per month
• Expense management with OCR (receipt scanning)
• Real-time financial dashboard
• Client and supplier management
• Product and service catalog
• Integrations with Stripe, PayPal, banks
• Open API and webhooks
• Verifactu-ready

What it does not include:

• Unlimited invoicing (paid plans start at 15 EUR/month for Pro, 29 EUR/month for Business)
• Team features (multiple users)

Contasimple (Cegid): 12 documents per year

Contasimple has a free plan, but its limit is very restrictive: 12 documents per year. A document can be an invoice, a quote, or an expense. If you issue one invoice per month, you have already used your full quota.

What the free plan includes:

• 12 documents per year (invoices + quotes + expenses combined)
• Basic accounting
• Tax forms (Modelo 303, 390, 130)
• 1 user

What it does not include:

• More than 12 documents (Professional plan costs 10.95 EUR/month)
• OCR
• API
• FacturaE electronic invoicing

Verdict: Contasimple’s free plan works as a demo, but 12 documents per year is not enough for real invoicing. A freelancer with regular activity will exhaust it in the first month.

Alegra: 10 invoices/month with AI

Alegra is a Colombian platform with growing presence in Spain. Its free plan allows 10 invoices per month, with AI features included.

What the free plan includes:

• 10 invoices per month
• Expense management
• AI-powered invoice creation by voice
• PDF scanning
• Verifactu compatible

What it does not include:

• API (only in Pro plan, ~18 EUR/month)
• More than 10 invoices
• CRM or project management
• Advanced inventory

Verdict: A good option if you issue few invoices and are interested in AI features. The 10-invoice monthly limit is somewhat tight for freelancers with regular activity. Alegra is relatively new in Spain and its support is centered in Latin America.

The AEAT’s free invoicing tool

Spain’s tax authority (AEAT) offers a free tool for issuing electronic invoices. It is 100% free, with no volume limits, and complies with regulations by definition.

What it includes:

• Electronic invoice issuance
• FacturaE format
• No document limits
• Guaranteed regulatory compliance

What it does not include:

• Expense management
• Automatic quarterly VAT calculation (Modelo 303)
• OCR for receipts
• Financial dashboard
• Client CRM
• Bank or payment gateway integrations
• Payment reminders
• Financial reports

Verdict: It is an issuance tool, not a management tool. If you only need to issue an occasional invoice, it works. If you invoice regularly and need to manage your finances, it falls short. It does not calculate your VAT, does not organize your expenses, and does not tell you how your business is doing.

Not free, but worth mentioning

Holded — from 15 EUR/month

The market leader in Spain. No free plan. 14-day trial with 50% off for the first 3 months. After that, the cheapest plan (Plus) costs 15 EUR/month. The Business plan with inventory costs 59 EUR/month, plus an extra 25 EUR/month for the inventory module.

Holded is a good product, but its pricing model includes add-on modules that can increase the bill quickly. If you only need invoicing, paying 15-59 EUR/month may not make sense when functional free options exist.

Quipu — from 14 EUR/month (annual)

No free plan. The Starter plan costs 17 EUR/month (or 14 EUR with annual billing). Includes Genius AI and 30 OCR scans per month. The API is only available from the Solution plan (25 EUR/month annual).

Billin — from 6.60 EUR/month

No free plan. The Basic plan starts at 6.60 EUR/month (+VAT) with a limit of 5 clients. The Pro plan (12.50 EUR/month) expands to 50 clients. Billin focuses purely on invoicing — no CRM, projects, or full accounting.

Anfix — from 4.99 EUR/month (annual)

No free plan. The cheapest plan limits you to 60 invoices per year (5 per month) for 4.99 EUR/month with annual billing. The API is only available in the Premium plan at 79.99 EUR/month.

Which to choose based on your situation

What really matters when choosing

Price is important, but it is not everything. When evaluating invoicing software, focus on three things:

Real limits of the free plan. 10 invoices per month is not the same as 12 per year. Read the fine print before investing time in setting up a tool.

Included features. Does it manage expenses? Does it have OCR? Does it calculate your quarterly VAT? Does it integrate with your bank? A program that only issues invoices forces you to use spreadsheets for everything else.

Verifactu readiness. Electronic invoicing will be mandatory in Spain. Choosing software that is not prepared now means migrating under pressure later.

If you are starting out as a freelancer, the best advice is this: start with a free plan that actually works, not a trial that forces you to pay in 14 days. Test the tool with your real workflow. If after a month it works for you, your decision is made. No rush, no pressure, no credit card required.
