I'm single country e-commerce (atm) and I have entered all my products including VAT, both cost and sales price.
What makes me confused is that if I uncheck the "Charge tax on this product" I get margin and profit displayed. If I check it I do not.
What is the right way to go? Should I enter all product data with our without vat/tax and what are the pros and cons in relation to my current setup?
