Aruba Fattura: Best for Micro-Businesses and Freelancers

Aruba is Italy's largest web hosting and digital services company — their e-invoicing platform benefits from this scale. Their SDI integration is one of the most reliable in Italy, with 99.9% uptime history.

What Works Well

• Free up to 5 invoices/month — the most generous free tier among major Italian providers
• Aruba PEC email integration — if you already use Aruba PEC (certified email), invoices route seamlessly
• Excellent SDI uptime — Aruba's infrastructure is used by hundreds of thousands of Italian businesses
• Simple, clean interface — suitable for non-accountants
• Conservazione sostitutiva built in at all tiers

Limitations

• No double-entry accounting — Aruba is invoicing-only
• Limited ERP integration options
• Customer support can be slow for complex issues

Pricing

• Free: up to 5 invoices/month
• Small: €1.99/month (unlimited invoices, basic features)
• Premium: €3.99/month (full features, priority support)

Best for: Freelancers (liberi professionisti), partite IVA in regime forfettario, micro-businesses issuing fewer than 50 invoices/month.

Fattura24: Best for Small Businesses and Growing SMEs

Fattura24 is a dedicated e-invoicing and document management platform built specifically for the Italian market. Unlike Aruba, it has a stronger focus on workflow automation and customer-side features.

What Works Well

• Excellent invoice workflow — send, track, and get paid from one platform
• REST API — integrates with custom e-commerce, CRM, and accounting tools
• Client portal — your customers receive a professional notification with invoice download
• Automatic payment reminders — reduces accounts receivable workload
• Conservazione sostitutiva via AGID-certified partner (included)

Limitations

• No native Peppol access point (EU cross-border invoicing requires a separate service)
• Free tier limited to 3 invoices/month — less generous than Aruba
• No built-in accounting/bookkeeping

Pricing

• Free: 3 invoices/month
• Starter: €5/month (100 invoices)
• Pro: €12/month (unlimited + API)

Best for: Small businesses (1–20 employees) that send 10–200 invoices/month and want workflow features beyond basic SDI submission.

Zucchetti Infinity: Best for Mid-Market and Accountants

Zucchetti is one of Italy's largest enterprise software vendors — over 40 years in business, serving 130,000+ Italian businesses. Their Infinity platform is a full ERP, not just an invoicing tool.

What Works Well

• Full accounting suite — not just invoicing; full Italian bookkeeping (IVA liquidazioni, F24, bilancio)
• Native Peppol access point — cross-border EU invoicing without separate services
• Accountant/commercialista friendly — widely used by Italian accounting firms
• Advanced reporting and analytics — spend visibility across all suppliers
• Regulatory updates — Zucchetti's legal team monitors Agenzia delle Entrate updates and pushes compliance updates to all customers

Limitations

• More expensive than Aruba or Fattura24
• Requires setup by a Zucchetti partner for full configuration
• Overkill for micro-businesses or simple invoicing needs

Pricing

• Starts from approximately €15/month for the invoicing module
• Full accounting suite pricing requires a Zucchetti partner quote
• Enterprise pricing available

Best for: Mid-market Italian businesses (20–200 employees), businesses with complex accounting needs, or businesses working with an Italian commercialista who uses Zucchetti.

Which Should You Choose?

Choose Aruba if: You are a freelancer or micro-business (regime forfettario or regime ordinario with low invoice volume), you already use Aruba PEC, or you want zero cost.

Choose Fattura24 if: You are a growing small business (5–50 employees), you need API integration for e-commerce or CRM, or you want professional invoice delivery workflows.

Choose Zucchetti if: You are a mid-market business needing full Italian accounting compliance, you work with an accountant who uses Zucchetti, or you need cross-border Peppol invoicing.

One Thing All Three Do Well

All three platforms handle the most important thing correctly: SDI submission and conservazione sostitutiva are included at every tier. You will not get hit with surprise fees for legal archiving. This is the baseline standard in Italy, and all three meet it.
