CBI B2B E-INVOICING: linking the logistical and financial cycle


E-invoicing, which is a link between administrative and financial processes, is an important step towards a more complete integration of the entire order/delivery/invoicing/payment cycle within organisations, and particularly in the network of relations with customers and suppliers.

The “electronic” method clearly facilitates archiving, searching, exchange and reconciliation processes, thus making the entire commercial, logistical and financial chain potentially automated.

In addition, the invoice can be advanced (financed) electronically by the bank to ensure optimal cash flow management. In addition to faster, simpler processes, integration between the invoice and payments/loans offers considerable savings of up to 70-80% compared to the operating costs involved in ordinary paper invoicing.

One of the important functions that Intermediaries can offer to customers through CBI is the “End-to-end sending of structured documentation” Service (e-Invoicing), which forms part of the Document Management Services Area.


PA E-INVOICING: connecting companies and public administrations


Law no. 244 of 24 December 2007 (Budget Law 2008) established that invoicing to public administrations must only take place electronically via the Interchange System. The rules were then defined by:

  • Ministerial Decree 55/2013 laying down provisions on the format, issue, transmission and receipt of e-invoices;
  • Law Decree 66/2014 (the IRPEF Decree 2014), which governed the implementation of the e-invoicing obligation towards the Public Administration:
  1. from 6 June 2014 e-invoicing is obligatory for Ministries, Tax Agencies, and national social security/welfare agencies;
  2. from 31 March 2015 the obligation has also been applied to all other administrations.

CBI promptly defined an architectural model allowing to transmit, and therefore issue, e-invoices to Public Administrations over the CBI network.


B2B SDI E-INVOICING: the advantage of dematerialising business relationships


The additional component was put in place by Decree 127/2015. The Decree establishes that starting from 1 January 2017, the Ministry of Economy and Finance (MEF) extends - as an option - the functionality of the Interchange System (hereinafter “SDI”) also to e-invoices between private entities.

The Budget Law 2018 (Law 205/2017), which came into force on 1 January 2018, introduced a new important change by establishing the e-invoicing obligation also in relations between private entities. In particular, the aforementioned Law established that:

  • from 1 July 2018, the obligation applies to the sale (and purchase) of fuels and transactions carried out within the chains of subcontracts with the PA end customer;
  • from 1 January 2019, the e-invoicing obligation applies to all transactions between Italian residents.

Starting from these dates, e-invoices - prepared in the XML format already in force for invoices to the Public Administration - must be transmitted to customers that are resident, established or identified in Italy, through the Revenue Agency SDI.

Since January 2017, CBI, which was already qualified to connect to the Interchange System, developed the CBI SDI Invoice Service, which allows member Intermediaries to send e-invoices and summary data to the Revenue Agency, on behalf of their customers, in full compliance with the relevant legislation.
