A panel discussion at EXPP made it clear that further clarification is needed to make it clear what the EU Commission means with equal treatment of paper and e-invoicing. The VAT directive states that business controls are sufficient. Now people ask what does that mean? What kind of business controls?
The best way to fend off scare mongering - is to keep messages very simple. "If you send or receive paper invoices today and plan to start using e-invoices you can continue using the same business controls as before."
This also goes for e-mail invoices - even if all efforts should be made to move away from PDFs as they are not really enabling the automation of process the whole exercise is all about.
