The problem

ITC claims depend on suppliers filing GSTR-1 and GSTR-3B on time.
Party masters drift: wrong legal names, cancelled registrations, stale addresses.
Bulk re-verification is slow and expensive with per-seat tools.

The flow

1GST Verify on invoice entry₹0.75 per check confirms status and legal name.
2GST Returns monthlyTwelve periods of GSTR-1/3B status per supplier, ₹1.00 each.
3Bulk re-verifyDrop a CSV of your party master; invalid rows are skipped at ₹0.
