The e-fff 1.0 version dates from the beginning of the protocol, around 2011. In the meantime, electronic invoicing standards have evolved and a new version is now available: ubl 2.1
Taking into account other developments in the electronic invoicing market, we have updated the e-fff version.
You will find below the differences between the 2 ubl versions
A set of e-fff v3 invoices is now available. It contains about ten standard invoices. The PDF version does not always mention the specificities of discounts and VAT calculations. On the other hand, the information in the e-fff is present.
