The billing phase of HoReCa will be independent of the purchase of Prism, which may have been purchased by an electrician while HoReCa is being paid for by the owner of the facility where Prism was installed.
So it will be possible to continue to use HoReCa even when it becomes chargeable using the customer’s tax ID number (PRIVATE) and not the current VAT number (BUSINESS or FREE PROFESSIONAL).
