The e-invoicing process in Italy:
- Invoice creation: Vendors generate electronic invoices in the FatturaPA format, ensuring compliance with legal requirements.
- Submission: Electronic invoices are submitted via the “Sistema di Interscambio” (SDI), a centralized platform managed by the Internal Revenue Authority.
- Validation: The SDI platform verifies the compliance of submitted e-invoices before forwarding them to the appropriate public administration or private entity.
- Processing: Public authorities and private entities process the e-invoices received. The system accommodates various transmission methods, including certified email (CEM) and Electronic Data Interchange (EDI).
Archiving: E-invoices must be archived for a period of 10 years to meet legal requirements.
