It is not just a question of creating an invoice in XML format, but it must be digitally signed and sent to the recipient via the Revenue Agency's interchange system.


Currently from our management system we issue an invoice, print it or send it via PDF to the customer (in this case the customer will print it). We give a copy of the invoice to the accountant, together with the supplier invoices received. After the tax return, our accountant will return those paper invoices to us, and we will put them in a folder or box in a safe place to keep them for 10 years available for any checks.


Simplifying in most cases, assuming the use of a replacement storage system, for example Aruba, Keliweb, Register, 2C Solution, etc.

With electronic invoicing, again from our management system we will issue the invoice, but this time without printing it, we will save it locally on our PC in XML format at this point that XML file instead of sending it via email, we will upload it to the replacement storage system that we have chosen that it will send it to the customer and archive it. This is the ACTIVE cycle.

The passive cycle is much simpler, to our suppliers we will give over the VAT, also the PEC and our SDI. In this way the exchange system will make sure to save it directly in our fiscal drawer.

If our electronic storage system allows it, we will be able to give our accountant access to both the archive of the invoices issued and received. And the Revenue Agency will have the possibility to carry out the checks in a simple and very fast way and thanks to the XML rd format perform any type of analysis of the same, which with paper was complex and required a lot of time.

There will also be many advantages for us VAT numbers, the first is that the XML format allows you to quickly import the invoices of our suppliers into our management system. For example, it will be possible to load the warehouse with a simple click, same thing for the first note, etc.


Not all, many still believe that "electronic" stands for the PDF file sent, by email, others are still too anchored to paper and do not know even if they have been working for years with the computer, the file system and therefore not knowing how to manage files and folders they will find themselves in difficulty. Yet conceptually there is no difference between printing, mailing and archiving a paper invoice or saving in XML, sending and archiving an electronic invoice.

Arte e Informatica aware of the difficulties of the transition to electronic invoicing, has developed modules and management systems perfectly integrated with PrestaShop, which will help to manage this step in a simple and immediate way.

Electronic Invoicing Fields for PrestaShop 1.6 and 1.7 (also compatible with Thirty bees v. 1.0.7): the module allows our customers to enter the Recipient Code / Intermediary SDI fields and the PEC (Certified Electronic Mail ) for the purpose of issuing the electronic invoice in XML format and sending it through the exchange system of the Revenue Agency.
