Can I issue an Italian e-invoice from AccountsOS?

## Can I issue an Italian e-invoice from AccountsOS?

No. E-invoicing through the Sistema di Interscambio (SDI) is mandatory for every partita IVA holder, including forfettari. An invoice legally exists only when it has been transmitted to SDI. AccountsOS does not transmit to SDI.

## What that means

A PDF invoice issued from AccountsOS is not a legal Italian invoice. The legal invoice is issued through the Fatture e Corrispettivi portal of the Agenzia delle Entrate, or through your own SDI provider.

## What AccountsOS does instead

AccountsOS keeps the books. It records the invoice, tracks it, and reconciles the payment when it arrives in the bank feed. When you ask Finn to send an invoice, Finn explains the gap and offers to record the invoice and track the payment.

## Details SDI needs

• The recipient is addressed by a 7-character codice destinatario or by PEC.
• SDI rejects an invoice whose buyer partita IVA or codice fiscale is not in the Anagrafe Tributaria.
• Finn can store the buyer's partita IVA or codice fiscale and their codice destinatario or PEC on the contact, so you have them for your SDI tool.

## Received invoices

Received e-invoices arrive as FatturaPA XML. Forward the PDF copy that your SDI tool or supplier provides to Finn, which posts it to the books as a bill for review. Finn does not yet read FatturaPA XML files, so an XML-only attachment is not ingested. Ask for the PDF.

## What stays manual

Creating the FatturaPA XML and sending it to SDI, and handling SDI rejections and notifications, stay with you. A commercialista can confirm invoice data where you are unsure.
