Hello All,

My client is in the business of providing manpower services, the thing is he did not show the bills in the month of january return but he paid GST on those bills and one more thing he has filed the GSTR 9 with same figures with out any rectification so that there is difference in turnover between books and GSTR 9, as we can't revise return GSTR 9 can I do anything in GSTR 9C??
