I am wondering what the correct tax settings should be in my situation, since I am currently getting some very odd results.
How it should be is that all prices on the site are tax included, and discounts should apply on the prices INCLUDING tax. So if I buy a product of €100 (tax included) en get €50 off the total price should be €50 (tax included).
And sure on the site all product prices are correct, they are displayed including tax. I tried a discount code which gives me the product for free and should give me free shipping.
As you can see my total is zero. Shipping is free, and the total in checkout is also zero. So all correct there.
However if I now go to the admin backendm checkout the order, which is still zero
and want to create an invoice for this order, I get this.
All of sudden tax and often also shipping is added to the invoice anyway. Which is the tax on the product.
This makes no sense to me. Are my tax settings wrong or is there something wrong with my Magento installation somewhere?
