1) Sending a long sheet of paper to subcontractor.
2) Subcontractor cuts circles on it and send to Main vendor.
3) Case-1- that cutting circle are fixed ratio
4) Case-2- cutting circles not have fixed ratio
5) At the same time subcontractor send wastage material to main vendor and main vendor sale that scrap material to customer and generates revenue.
