A retailer  got input GST from purchaser but when he sold medicine he did not charged GST from customer because it is the billing system of all medicine dealer that they can not charged seperate GST to customer, he is a regular dealer, not composite , so my query is how he show his output GST or what is the rules for medical shop, plese infome me.
