This is a weird problem.
I have my shop live now with Hikashop.
There is how ever a problem with VAT-calculation.
In the order listing in the backend some products are listed under "Unit Price" with price + VAT and some are just listed with the price and no VAT. It seems like this makes the VAT calculation go wrong.
Products in the same category displays differently some with VAT and some without.
In the Checkout the items are listed with their prices without VAT as I want, but the VAT amount is way off. I just did a test and the subtotal without VAT is correctly at 28690.00 and then there is the shipping of 500.00 total 29190.00. VAT is 25% on this 7297.50 but Hikashop shows VAT of 11697.50 and the total of 35970.00.
The last two amounts are wrong, the total should be 36487.50
