audit Certificate on anti profiteering clause under gst .

I have not practically done the same but the procedure should be following:
1. Prepare a cost sheet containing details of Input, Input service & Capital items.
2. Determine the cost of goods produced in case of manufacturing concern and cost of service in case of service provider.
3. Now Compare the existing selling price and cost to determine the mark up or profit.
4. Now prepare the cost sheet as per new provision.
5. add the mark up and determine the selling price.
6. Compare the selling price as per old and new provision.

thanq for your inputs
