lets say my selling price is $10, tax rate is 6%, usually total price is $10.60
now i would like to include the tax in my selling price as below
selling price included tax is $10 so the price before tax should be $10/1.06=$9.43, tax amount should be $0.57 total sum up = $10
my question is, how to setup an auto calculation for each product’s selling price to divide by 1.06 when added to order list?
