Fattura24 Review 2026: Best Free E-Invoicing App for Italian Freelancers?

Fattura24 has built a strong reputation among Italian freelancers and tech-savvy small businesses since 2012. It offers a genuinely free tier, a clean modern interface (rare in Italian software), and a developer-friendly API. But is it the right choice for your situation in 2026?

This review is based on hands-on testing — we created a free account, generated multiple FatturaPA invoices, submitted them through SDI, and tested the API.

Quick Verdict

Fattura24 is excellent for:

Italian freelancers under regime forfettario with low invoice volumes
Developers who need a clean FatturaPA API
Tech-forward SMEs that want a modern, fast interface
e-commerce businesses (WooCommerce, Shopify integrations)

Consider alternatives for:

High invoice volumes (free tier is 3/month — paid tiers needed beyond that)
Businesses needing full accounting/bookkeeping (Fattura24 is invoicing-only)
Large enterprises requiring deep ERP integration

Free Tier: What Do You Actually Get?

The Fattura24 free plan includes:

3 invoices per month (FatturaPA, credit notes, receipts)
SDI transmission and receipt
Conservazione sostitutiva (10-year digital storage)
Email notifications on SDI status
PDF + XML download of all invoices
Basic customer registry (unlimited contacts)

This covers most regime forfettario freelancers who send 1–3 invoices per month. For higher volumes, the paid plans start at:

Plan	Invoices/month	Price
Free	3	€0
Start	50	€5.90/month
Professional	Unlimited	€11.90/month
API Pro	Unlimited + API	€19.90/month

FatturaPA Compliance

SDI Submission

Fattura24 is a certified SDI intermediary (intermediario SDI). When you send an invoice:

You create the invoice in Fattura24's interface (or API)
Fattura24 generates the FatturaPA XML (version 1.3, current Italian standard)
Fattura24 submits to SDI and monitors the status
You receive notifications of acceptance, rejection, or delivery

In our testing, SDI submission was reliable. Invoices showed SDI status ("consegnata" — delivered) within 30–90 minutes, which is normal.

Conservazione Sostitutiva

Fattura24 includes 10-year digital storage in all plans (including free). The storage is provided by a certified Italian conservazione provider and meets AGID accreditation standards.

Important: Verify in your account settings that conservazione is activated. It is enabled by default for new accounts, but worth confirming.

Codice Destinatario and PEC

Fattura24 correctly handles both:

7-character Codice Destinatario — the standard routing code
PEC address — for recipients that prefer certified email delivery
0000000 — the fallback code for recipients without a specific code (used rarely, with caution)

PA Invoicing (B2G)

Fattura24 also handles public administration invoices (the "PA" variant of FatturaPA), including the mandatory CUP (Codice Unico di Progetto) and CIG (Codice Identificativo di Gara) fields for government contracts.

The Interface

Fattura24's UI is genuinely one of the best in the Italian market. It is:

Mobile-responsive — works well on both desktop and mobile
Fast — page loads are quick, no legacy server-side rendering lag
Intuitive — creating an invoice takes about 2 minutes once you know your customer's codice destinatario
Multi-language — English interface available (rare for Italian invoicing software)

The customer registry remembers all your clients' details including their Codice Destinatario and Codice Fiscale — subsequent invoices to the same client take under a minute.

The API: A Developer's Perspective

This is where Fattura24 genuinely stands out. The API is clean, well-documented, and actually enjoyable to work with.

Authentication

Bearer token authentication. Tokens are generated in your account settings.

Create an Invoice via API

POST https://www.app.fattura24.com/api/v0.3/SaveDocument
Authorization: Bearer YOUR_API_KEY
Content-Type: application/json

{
  "document": {
    "type": "FT",
    "date": "2026-05-01",
    "clientId": "12345",
    "rows": [
      {
        "description": "Web development services - May 2026",
        "qty": 1,
        "price": 2500.00,
        "vatCode": "22"
      }
    ],
    "paymentType": "MP05",
    "iban": "IT60X0542811101000000123456"
  }
}

The API returns the internal document ID, which you use to trigger SDI submission.

Webhooks

Fattura24 supports webhooks for SDI status updates — critical for automated workflows. You register a webhook URL in your account, and Fattura24 POSTs a status update when the SDI processes your invoice (accepted, rejected, delivery confirmed).

WooCommerce Plugin

The official Fattura24 WooCommerce plugin automatically generates FatturaPA invoices for orders. Works reasonably well for e-commerce; the free tier's 3-invoice limit means you will likely need the Pro plan for an active store.

Fattura24 vs. Aruba: Which to Choose?

Feature	Fattura24	Aruba
Free tier	3 invoices/month	Unlimited basic (check current terms)
Interface	Modern, fast	Functional, dated
API quality	✅ Excellent	⚠️ Available but less developer-friendly
Mobile app	✅ Good	✅ Available
Conservazione	✅ Included	✅ Included
PEC integration	Via customer data	✅ Native (Aruba is Italy's main PEC provider)
WooCommerce plugin	✅ Official	⚠️ Third-party options only
Volume pricing	From €5.90/month	Check current Aruba plans

Choose Fattura24 if: You are a developer, e-commerce business, or modern SME that values a clean interface and API quality.

Choose Aruba if: You also use Aruba PEC (certified email) and want native integration, or you need Aruba's more established enterprise-scale infrastructure.

What Could Be Better

Free tier is limited to 3 invoices/month — freelancers with more than 3 monthly invoices will need to pay
No full accounting — Fattura24 is invoicing only; you need separate software for bookkeeping
Support response time — documentation is good, but live support can be slow
No cross-border e-invoicing natively — Peppol support is via API only, not a native feature

Bottom Line

Fattura24 is one of the best Italian e-invoicing tools for freelancers and small businesses — particularly those who are tech-forward, use e-commerce platforms, or need a developer API. The free tier covers low-volume freelancers, and the paid tiers are competitively priced.

If you issue more than 3 invoices per month (very common for freelancers), the €5.90/month Start plan is excellent value. If you need a full accounting suite, pair Fattura24 with a separate bookkeeping tool or switch to TeamSystem or Zucchetti.
