  • Sender or Supplier.
  • Interchange System (SDI).
  • Public administration.

WHAT IS AN ELECTRONIC INVOICE

The electronic invoice, invoice in digital format, is a document in XML format that follows its own mandatory formatting. This type of invoice guarantees the sender's authenticity and integrity, combined with the guarantee of non-modification or tampering.

These elements are formalized through the digital signature of the person issuing the accounting document. Put simply, you can define the electronic invoice as an evolution of the traditional billing system, which allows the sender and receiver to obtain the security of a protected file.

The obligation of electronic invoicing, in force since 6 June 2014 for tax agencies, ministries, national social security and social assistance bodies, has been extended to all PAs (Public Administrations) since 31 March 2015. From 1 July 2016 it has been introduced for taxpayers the possibility of having the electronic invoice for free by benefiting from a system, made available by the Revenue Agency, for electronic invoices exchanged between private individuals and for transmitting and storing the invoices themselves. The procedure can be used by connecting to the Revenue Agency website or through the app, which can be installed free of charge on all Android and iOS mobile devices.

This factor is fundamental for the identification of the holder. Once the invoice with all the tax data has been completed, it must be digitally signed.

Here comes the Identification Service, also known by the acronym of SDI. It is a platform that acts as a bridge between sender and recipient and which uses a particular control method that verifies the completeness of the data on the invoice, guaranteeing its correctness. Once everything has been validated, including the unique code mentioned above, the SDI sends the tax document to the corresponding Public Administration office.

To find out the details concerning a specific Public Administration Body, it is possible to access the Index of Public Administrations, a list with an internal search engine structured and able to provide various requests. You can proceed by alphabetical order (PEC address of the office), by category, tax code, type of service, geographical area and even via social networks.
