E-Invoicing Mandate in Italy (SdI)
Prepare your business for the Italian e-invoicing mandate. Ensure your invoices meet the requirements of the Sistema di Interscambio (SdI) and are transmitted to tax authorities on time.
What is the Sistema di Interscambio?
The Sistema di Interscambio (SdI) is the central platform of the Italian Revenue Agency (Agenzia delle Entrate) for the exchange of electronic invoices. Since 2019, companies based in Italy must send structured B2B and B2C invoices in XML format to the SdI. The platform validates the invoices and routes them to the recipient or directly to the tax authority.

Frequently Asked Questions
Answers to the most common questions about the Italian e-invoicing mandate.

Yes, it is legally required for all companies based in Italy, as well as for foreign companies with an operational branch in Italy.
Invoices must be submitted to the SdI by the 15th day of the month following the month of invoice issuance. However, real-time transmission is highly recommended.
If the SdI rejects an invoice (e.g., due to formatting errors), the invoice must be corrected and resubmitted. Our system instantly notifies you of rejections and helps resolve the errors.
