Italy started e-invoicing in public administration (FatturaPA) in line with the EU Directive in 2014. As of January 1, 2019, it has expanded to B2B and B2C format e-invoices, which will be mandatory in all companies in Italy.

With the e-invoice platform, Sistema di Interscambio (Exchange system-SDI) managed by the Italian Revenue Administration,

  • Receiving invoices in file format,

  • Making checks on the received files,

It is possible to forward the invoices to the recipient public administrations to businesses/customers (B2B and B2C).

E-invoicing flow in SdI:


According to the image, e-invoices sent/received from businesses to SdI, from SdI to public administration (and vice versa) are processed through 4 different channels.

1. PEC (Postal Elettronica Certificata – Electronic certified mail)

PEC features

  • Guarantee the sending and receiving of messages and all attached documents

  • Legally approving the sending and receiving of messages, such as a registered letter with receipt

For taxpayers who have an e-mail account approved by the Italian Digital Agency, it is possible to send invoices with PEC. However, with FatturaPA, archive files should be sent to in addition to the PEC message, not exceeding 30 megabytes.

The taxpayer using the PEC channel will receive the messages generated by SdI in the PEC e-mail account he sends.

2. Sendvia web (Invio via web)

The channel allows you to send a FatturaPA file or an archive file via a web interface. For this, you must have Entratel or Fisconline credentials or a National Service Card (CNS) or SPID (Public Digital Identity System) credentials that have been pre-activated for the Revenue Agency’s electronic services. The file sent over the web must not exceed 5 megabytes in size.

The taxpayer, who uses the web channel to send files, will be able to view the message files related to their sending via the Monitor FatturaPA application in the Online Services section.

3. Sending e-invoices with SDICoop

SDICoop – Transmission Service is available for taxpayers who want to send FatturaPA files and receive message files using the web. To use this transmission channel, you must accredit with SdI on the site.
