19% Vat in Affiliate, Membership and Pro Sites


before my Purchase you told me I can ask you this questions in the support tread. No it´s time for it..

Here in Germany we have to add 19% vat on everything we sell. It is very important for us to sign every price-value with the Information: "include 19% vat", or in german: "inklusive 19% Mehrwertsteuer"

We need invoices like this:
Tutorial: € 25,20
Vat 19%: € 4,79
Total: € 29,99

What´s the best way to handle this, please?

Best regards
