- Italy has had e-invoice obligations since 2014, using the SDI system for sending and receiving e-invoices
- In Italy, e-invoices must be formatted according to the “FatturaPA” standard based on XML
- Each invoice transmitted through the SDI must include a unique identifier for the recipient
- Invoices may also feature a PEC address for direct receipt in a dedicated “invoice inbox”
- Companies can exchange copies of invoices through mutually agreed methods in addition to the SDI
- Italian law mandates that all invoices be archived for a decade by both the sender and recipient
