Fattura elettronica
Also known as: e-invoicing, FatturaPA, SDI
Italy requires invoices to be issued electronically as a FatturaPA XML file, transmitted through the Sistema di Interscambio (SdI) — the Agenzia delle Entrate's hub that validates and delivers them. Since 2024 this applies to virtually all partita IVA holders, including those on the forfettario.1
What this means for you
You can't just email a PDF: invoices must go through the SdI, usually via your accounting software or a provider. Each invoice carries a recipient code (codice destinatario) or the client's PEC, and must be issued within 12 days of the transaction.
