Sistema di Interscambio (SdI) is an information system providing you with the possibility to send and receive electronic invoices. It can be compared to a mail sorting centre that checks and forward all incoming e-mails and sends back all the e-mails that cannot pass specific tests. This system is currently used for the relations with Public Administrations, small and medium companies and individuals to send and receive electronic invoices by law, since 1st January 2019.
Any action processed by SdI provides you with a confirmation message when the operation has been successfully processed or a failure message in case of rejection of the electronic invoice.
