Normally in VAT countries when a bussines is dealing with a private person they state the price VAT included because a privat person has to pay VAT
When it is bussines to bussines the price without VAT is stated because a bussines with a VAT nr gets a refund of the VAT
On a international deal VAT is not requiered
So his questin is really if the price is with or without VAT or any local equivalent
(On all invoices you write for your customers you ad the VAT
Then every 3months or so you have to pay or get refunded the balance of all the VAT from all the invoices you wrote and all the ones you recieved
I understand that system more or less

How they tax you in the US is still a mystery to me
