We were almost there....but...
Issue 1 = The grand total is to much cause the script still counting 19 procent tax from the tax included prices
Example: Product price is 119 (imagine that customer orders just one)
Tax: 22 (?????)
Grabt Total: 141
What I like to see is:
Product price = 119 (imagine that customer orders just one)
Grand total: 119
Issue 2 = In the product list all the prices are without taxes
Issue 3 = In the back end I always must enter the tax exclusieve prices
What I tried was to set the TAX rate to 0 (zero) at the back end but than I don't see any tax in the cart page at all.
