Seven Years of FatturaPA: What Italian Accountants Actually Think

Italy introduced mandatory B2B e-invoicing in January 2019 — making it the first EU country to do so at scale. Seven years later, the SDI system is processing over 1.2 billion invoices a year, and the dust has well and truly settled.

But what is the day-to-day reality for the people who actually use it?

I spent time speaking with accountants (commercialisti) and small business owners across northern and central Italy — the people who handle this every day. Here is what they told me, in their own words.

Giulia, 52, commercialista in Verona

"January 2019 was chaos. I had clients calling me every day — 'the SDI rejected my invoice', 'what is a codice destinatario', 'why did it come back with a PA04 error'. My office added three extra staff just to handle the transition questions.

But by March, most clients had settled into a routine. By June, it was just... normal. The SDI rejects are immediate now — you know within hours if something is wrong, not three weeks later when the customer calls to say they never received it.

What I didn't expect: my clients actually get paid faster. The invoice arrives instantly, it's validated, it's in the buyer's system automatically. There's no 'I never received it' any more."

"Nobody told me that I also needed to pay separately for conservazione sostitutiva — the legally required 10-year digital archive. My accountant uses Aruba, which includes it, but when I tried to manage invoices myself through the Agenzia delle Entrate portal, I realised the archive wasn't automatic.

Small thing, but it cost me €80 the first year with a third-party provider until I switched to software that included it. Read the small print."

"I do maybe 15–20 invoices a year. I use the free portal on the Agenzia delle Entrate website — the one built into the Fatture e Corrispettivi section. It takes about 3 minutes per invoice once you know what you're doing. For my volume, it's completely adequate.

The SDI validation is instant. I've only had one rejection in seven years — I had the wrong codice fiscale for a new client. Corrected it in ten minutes."

"For Italian domestic invoices, everything works. But when we invoice our German customers — who now need XRechnung or ZUGFeRD, not FatturaPA — it's a whole separate system. We had to add a Peppol access point just for the German invoices.

The EU says ViDA will unify everything by 2030. I'll believe it when I see it. For now, if you invoice across borders regularly, you need separate processes for each country."

For other EU countries watching Italy's model: the transition is hard, the first few months are stressful, and then it becomes invisible infrastructure. That is the lesson.

1. Don't use the Agenzia delle Entrate portal for more than 50 invoices/year — it works, but software saves hours
2. Check your *codice destinatario* before sending — a wrong 7-character code means an immediate rejection
3. Set up SDI notifications — your intermediary can email or webhook you on acceptance/rejection
4. Confirm conservazione sostitutiva is included in your software contract, not charged separately
5. For cross-border invoicing — get a Peppol access point in addition to your SDI intermediary
