My client has shown in January 2018 sales in B2C instead of in B2B. now the purchaser wants to claim ITC. demanding enter sales to claim ITC. my query is how can we enter sales it has already entered in B2C. clarify any one .
The last date filing gstr1 for September 18 is 31st October. if we file gstr1 in month ending can the purchaser claim ITC since the deadline to claim ITC is 25 th october 18.
