The electronic invoicing between companies in Italy started on the right foot:

July 1st six months have passed since the entry into force of the rule, and in this period – more specifically from January 1 the beginning of June – were issued 854 millions of e-bills: 54% to businesses, 2% to the PA and 44% to individuals. 

3.2 million VAT numbers sent them, representing 64% of Italian companies: a higher number than those who would have been forced to switch to the new system.

These are some of the most significant data that emerge from the research of the  Electronic Invoicing & eCommerce B2b Observatory of the School of Management of the Politecnico di Milano  ( ), presented at the Bovisa Campus of the  Politecnico di Milano  during the conference ” Electronic Invoicing: a chance for change . ”

The impact on businesses was overall positive, since more than half said they had benefited from the process of receiving invoices, while 30% also saw improvements in sending. The main advantages, according to the study, are the possibility of accessing new data flows with the aim of improving business processes, more simply digitizing an increasing number of documents and boosting  digital transformation  also in transactions between companies.

”  Electronic invoicing  is not the digital transposition of a document or activity but a new organizational model that can be a trigger in the digitalization of the main processes between companies, between companies and the Public Administration and in dialogue with citizens – explains  Alessandro Perego , scientific director of the  Digital Innovation Observatories of the School of Management of the Milan Polytechnic – and can therefore ultimately help the country to recover the gap that separates it from the main European countries in terms of digital maturity. At least Italy is at the forefront of this: the first country in Europe to adopt the generalized electronic invoicing obligation and leader in the digitalization of processes in many supply chains. With specific reference to the obligation of electronic invoicing, many more companies than those subject to the obligation have decided to join, testifying to a judgment of usefulness that goes beyond the regulatory obligation “.

What emerges from all this is that we must not stop at regulatory compliance, but look beyond “.

What is electronic invoicing and how it works

Electronic invoicingWith the 2018 Budget Law, the Government established the mandatory electronic invoicing between all subjects resident in Italy. Not only PA but also B2B in the center of the legislation that promises to revolutionize the current Italian tax system.

To be defined as an electronic invoice, it must be complete , legible and authentic . The three characteristics are verified on the basis of the content of the invoice itself which must be corrected, with content not altered during the data transmission and transmission phase. Those who consult it must be sure that it comes from the provider and the content must be legible, therefore viewable on every type of device.

How to make electronic invoice authentic

Electronic invoicingIntegrity and authenticity are two factors guaranteed by the constant control carried out by the Revenue Agency systems. There must be a link between the invoice and the related supply of goods or services.

The electronic transmission of data, the electronic signature of the issuer and the sophisticated technologies made available by the Inland Revenue guarantee a clean, linear and transparent operation.

The PA invoice: what it is and differences with the B2B invoice

Electronic invoicingEntering into force for some time, she was the representative par excellence of the first experimental phase of electronic invoicing. By PA invoice we mean the invoice sent to public administration bodies .

It is a very common electronic invoice equal to those provided for B2B operations. It is transmitted with the Exchange System (SDI) , is in XML format and is marked with a digital signature. As well as a B2B electronic invoice, the one relating to the Public Administration is also delivered thanks to the unique identification code. It can be found in the IPA index, list containing the electronic addresses of the PA.

The PA electronic invoice varies according to the service or goods sold. In the case of public calls, it must necessarily contain the CUP , the unique project code.

The importance of the Unique Recipient Code and the PEC e-mail

Electronic invoicingThere is a lot of talk about a unique recipient code, an alphanumeric sequence consisting of seven characters that identifies the recipient of the electronic invoice. Its use is FUNDAMENTAL so that all electronic invoices are delivered to the recipient.

The recipient code is unique and defines the user company. In some cases it may indicate the intermediary who may be the service provider or the software manufacturer, as in the case of Edisoftware’s Digital Telematic System. In this case, only one unique recipient code will be available for each user company, even if the licensee is the same and belongs to multiple companies.

The PEC e-mail is also necessary for the correct performance of the service. It serves to identify the user company and brings numerous advantages in the digital management of the passive process. In fact, any errors or omissions will be reduced as the company will not have to communicate its electronic address individually but will make it available directly on the chosen hub.

The unique recipient code must be entered and registered on the Revenue Agency portal at   in the Invoices and Fees area. Then from the services menu choose the option “ Registration of the electronic address where you will receive all electronic invoices ”.
