Italy E-Invoicing Mandate
MandatoryFull B2B and B2G mandate — SDI clearing model
Italy operates a strict clearing house model through SDI (Sistema di Interscambio), one of the most comprehensive in Europe. The mandate covers all B2B and B2G transactions. Every invoice must be transmitted through SDI, which validates format, VAT numbers, and routing before forwarding to the recipient. The FatturaPA XML format is mandatory. Italy also implements CTC (Continuous Transaction Controls) for VAT — SDI acts as the real-time validation and reporting system.
