5% - 19% VAT Charge

[George P]

Hello,

I own an online store focused on green energy and photovoltaic systems. The government introduced another VAT tax for consumers, 5% to be exact.
Until now, these products had a standard VAT value of 19%. But the problem is that only consumers benefit from 5% VAT, while companies have 19%.
At the moment, all products in the catalog related to green energy have a 5% VAT rule.
I need help or a suggestion to be able to offer companies the opportunity to order, but they must be charged 19% VAT.
Any suggestion or solution is welcome. I'm sure solution is out there but I can't see it. 

P.S. these VAT regulations are available only for Romania, all the customers that land on the page if they are from outside Romania, they will not be allowed to order.

Thank you!
