Problems facing by tax payers

Its very difficult to reconcile the input tax received in GSTR 2.  Still the difficulty in identification of input tax is alive. Because in a large scale business, how we find out whether the supplier filed return for the tax payer or not. In GSTR 2 the GST number of supplier is there but at the same time we have no provision to see the Registered parties name or anything. At the time of filing the accuracy of GSTR2 is not predictable. At the beginning stage the offline utility have no option to verify the input tax. and then the utility developed to its next version and in the third stage the utility add the option of conversion of data into excelsheet. So i hope.... In future we will get more facilities...
