Dear Sirs,
One of our customers has 2 GSTIN one at Gujarat (24) and other at Madhya Pradesh (23).
During Aug 17 to Apr 18 (9 months) we uploaded sale invoices in GSTR! as Gujarat (24) instead of Madhya Pradesh (23)
Can we amend invoices in GSTR1 for FY 2017-18? how
Also Apr 18 has to be amended. My customer had held my GST for the error. PLS HELP
