Simplifying in most cases, assuming the use of a substitute storage system, for example Aruba, Keliweb, Register, 2C Solution, etc.
With electronic invoicing, we will still issue the invoice from our management software, but this time without printing it; we will save it locally on our PC in XML format. At this point, instead of sending that XML file via email, we will upload it to the substitute storage system we have chosen, which will take care of sending it to the customer and archiving it. This is the ACTIVE cycle.
The passive cycle is much simpler; we will provide our suppliers not only with the VAT number but also with the PEC and our SDI. In this way, the interchange system will ensure that it is saved directly in our tax drawer.
If our substitute storage system allows it, we can give our accountant access to both the archive of issued and received invoices. The Revenue Agency will have the ability to carry out checks easily and very quickly, and thanks to the XML format, it can perform any type of analysis on them, which was complex and time-consuming with paper.
There will also be many advantages for us VAT numbers; the first is that the XML format allows for the quick import of our suppliers' invoices into our management software. It will be possible to perform, for example, inventory loading with a simple click, the same for the journal entry, etc.
