Sistema di Interscambio (SdI): Who Qualifies and What You Get

The Sistema di Interscambio (SdI) is the mandatory digital platform used for electronic invoicing within the public sector in Italy. It serves as the central exchange point for digital billing between different public entities and their partners.

👤Who it's for

This system is mandatory for all public sector entities. If your organization functions as part of the public sector, you are required to use this system to manage your electronic billing and official documentation.

🎁What you get

By using this system, you gain access to a mandatory electronic invoicing system. This digital infrastructure is designed to ensure that all invoices are processed through a standardized, official channel, facilitating the exchange of required financial documents between different public bodies and their partners.

💰What it costs you

Using this system involves more than just a simple login. It requires integration with your existing accounting software. You will need to ensure that your internal financial tools are technically capable of communicating with the SdI platform to facilitate the seamless exchange of electronic invoices.

⚠️The catch to know

The most significant hurdle for many users is the rejection of invoices. This most commonly happens when an invoice is submitted with an incorrect PA code, also known as the Codice Univoco Ufficio. If this unique code is entered incorrectly, the system will not be able to route the document properly, leading to rejected files.

📝How to apply

1. Verify that your current accounting software is capable of integrating with the SdI platform.
2. Confirm you have the correct, specific PA code (Codice Univoco Ufficio) for the entity you are billing.
3. Set up your digital billing workflow to transmit documents through the electronic system.
4. Monitor your incoming and outgoing communications via the official portal to catch any errors.
