benefit of GST to large scale business organization

GST is the process in which your purchase and sale will be counted.and you need to pay gst on sale gst-purchase gst...which comes the gst on profit.for all kind of business it helpful as only realted to one tax in india..process is little bit complicated...till now and need to on it..in short gst is good for india..but bad for the people who didnt pay sale tax but enjoy taxpayer money...

thanks a lot ma'am
