E-invoicing in Italy is now a central component of the Italian tax system. At its core is SDI Italy, the Sistema di Interscambio operated by the Italian tax authority, Agenzia delle Entrate. Electronic invoices are transmitted, verified, and delivered to the recipient via this platform.
For POS companies, software providers, and ERP providers, it is crucial to understand how Italy’s SDI system works in order to comply with legal requirements correctly and efficiently.
In this article, we explain what SDI is, how e-invoicing works in Italy from both a technical and organizational standpoint, and what companies should keep in mind when implementing it.
SDI stands for Sistema di Interscambio and is the technical infrastructure through which all electronic invoices in Italy are processed.
The system receives invoices, verifies that they are formally correct, and forwards them to the appropriate recipient. This makes SDI the central interface between the invoice issuer and the invoice recipient.
Every electronic invoice must be submitted to the SDI before it is considered valid for tax purposes. As a result, the system plays an important role in ensuring the traceability and accuracy of tax transactions.
The process of electronic invoicing via SDI consists of several steps.
The invoice is generated in the XML format required by Italian law.
The document must include all required information, including:
Once created, the electronic invoice is transmitted via an accredited transmission channel to the Sistema di Interscambio (SDI), which manages the delivery and receipt of the corresponding notifications. The Sistema di Interscambio automatically verifies whether the document meets the formal requirements. Among other things, it checks the XML format, the validity of the VAT data, and the presence of all required information.
If the checks are successful, the invoice is sent to the recipient, and the sender receives a corresponding status notification.
SDI is used by most businesses and individuals subject to value-added tax who operate in Italy.
These include:
For international organizations operating in Italy, integration with SDI is an essential requirement for complying with regulatory requirements.
In addition to the legal requirement, electronic invoicing offers numerous operational advantages.
