Hi ,
i have entered the purchase price and added the Gross profit tab from the screen option. However, it seems the logic for the % gross profit seems to be incorrect as it deducts the difference between the Sale price and the purchase price, but it doesn't consider the 
10% GST portion already in the Sale price. This may be only relevant to the countries where the sale price must include the goods and services tax. Can you please advise how the logic can be corrected?
