SDI – Electronic Invoicing
The Sistema di Interscambio (SDI) is the Italian government’s electronic platform for the transmission, receipt, and validation of electronic invoices (fatture elettroniche). Since 2019, electronic invoicing through SDI is mandatory for all B2B and B2C transactions involving Italian VAT-registered entities.
SDI acts as a secure intermediary that receives invoices from suppliers, verifies them, and forwards them to recipients in line with Italian tax law.
Why SDI Matters
- Legal requirement: mandatory for Italian VAT-registered businesses, for domestic and cross-border invoices
- Tax compliance: automates VAT reporting and reduces errors
- Transparency: real-time tracking of invoices and payments
- Operational efficiency: faster reconciliation and audit processes
Who Must Use SDI
- All Italian companies registered for VAT (including foreign companies with an Italian VAT number)
- Public administrations receiving electronic invoices under the Fatturazione PA mandate
- Businesses involved in B2B and B2C transactions within Italy
