VAT deducted not added

Good Day Everybody,

we were reading through half the forum of this topic, but as of now we are not able to get the right answer we look for. Let me also say we are not IT experts so we have a hard time programming anything.

We look for an option in orders and invoices to have the VAT deducted, not added. Meaning the price for each item we add should be shown as VAT inc price. At the sum of the invoice there will be shown then the VAT EX, VAT 12% and of course also the VAT INC.

thanks for your help.
