Dear Sir/Madam,
I Filled my GSTR3B for the month of june2018 and i filled GSTR1 on quaterly, and taxes also paid.
In that one sale invoice was considered in GSTR-3B but not taken in GSTR1.
Because of not considered in GSTR1, the custemer is unble to claim his ITC on GST.
is it possible to modify my Quater1(Apr-Jun) GSTR1 return
Thanking you.
