Italian E-Invoicing Software Comparison 2026: Aruba vs Fattura24 vs TeamSystem
An honest head-to-head comparison of the top Italian e-invoicing platforms: Aruba Fatturazione, Fattura24, and TeamSystem. Pricing, features, and who each suits best.
Italian E-Invoicing Software Comparison 2026
Italy has one of the most mature e-invoicing markets in Europe — the mandate has been live since 2019, which means software providers have had seven years to refine their products. The result is a competitive market with several excellent options. The challenge is choosing the right one for your specific situation.
This comparison focuses on the three platforms most commonly evaluated by Italian businesses and their accountants.

Aruba Fatturazione Elettronica
Aruba is Italy's largest hosting, PEC, and e-invoicing provider. More than one million Italian businesses trust their FatturaPA invoicing to Aruba — a number that speaks for itself.
The case for Aruba: If you are a sole trader or small business that primarily needs reliable FatturaPA generation and SDI routing, Aruba's free tier covers the basics without spending a euro. The conservazione sostitutiva (10-year compliant archiving) is included, which many competitors charge extra for.
The case against Aruba: The interface was designed for maximum reliability, not maximum pleasure. Navigation can feel clunky. The feature set has not evolved dramatically since the early mandate days, and businesses that grow beyond basic invoicing often find they need to switch platforms.
Verdict: Best for sole traders, micro-businesses, and anyone whose primary need is bulletproof FatturaPA compliance at low cost.
Fattura24
Fattura24 entered the market in 2012 with a clearer ambition: build an Italian invoicing tool that developers and modern SMEs would actually enjoy using. Seven years after the mandate, it has grown into one of the most recommended platforms in Italian SME circles.
The case for Fattura24: The interface is genuinely clean and logical — a rarity in Italian compliance software. The REST API is well-documented, which makes it the first choice for e-commerce integrations, custom ERP connections, and any workflow that needs programmatic invoice generation. Native WooCommerce and Shopify plugins are available and actively maintained.
The case against Fattura24: The free plan is very limited (3 invoices per month). The platform is invoicing-focused — there are no built-in accounting or financial reporting features. For businesses that need more than invoice generation and SDI routing, you will need to pair it with separate accounting software.
Verdict: Best for SMEs with custom integration needs, e-commerce businesses, and developers who need a solid API. Also excellent for startups that have outgrown free tiers.
TeamSystem
TeamSystem is the enterprise player in this comparison. Founded in 1980, it has been the tool of choice for Italian commercialisti (accounting professionals) for decades. Its product range covers full ERP, payroll, tax declarations, and e-invoicing as a single integrated platform.
The case for TeamSystem: If you need a complete accounting and management solution — not just invoicing — TeamSystem is the natural choice. The depth of Italian tax compliance is unmatched: IVA registers, F24 payment management, annual dichiarazioni, and full conservazione sostitutiva are all integrated. Many Italian commercial accountants will already be familiar with it, which reduces consulting time.
The case against TeamSystem: It is more expensive than the alternatives and significantly more complex. Solo traders and small businesses with simple invoicing needs will find themselves paying for features they never use. The interface is functional but dated.
Verdict: Best for SMEs and mid-market companies that need full Italian accounting compliance, businesses whose commercialista already uses TeamSystem, and companies that need the full ERP feature set.
Our Recommendation
- Freelancer / sole trader / micro-business: Start with Aruba's free tier. It covers you fully.
- Growing SME, API needs, or e-commerce: Fattura24 is the modern, developer-friendly choice.
- Established SME or mid-market with full accounting needs: TeamSystem or its cloud sibling Teamsystem Digital for a modern UI.
- Multi-country operation: Consider Sage Business Cloud, which supports Italy alongside Germany and France.
