Common GST Pain Points We Solve

  • ITC mismatches causing excess GST payment
  • Late filing penalties accumulating over multiple months
  • Notices for GSTR-1 and GSTR-3B discrepancies
  • Blocked ITC under Section 17(5) being incorrectly claimed

Monthly GST Retainer

Most businesses benefit most from an ongoing monthly GST retainer arrangement — we handle GSTR-1 and GSTR-3B every month, send you a reconciliation report, and flag any discrepancies before they become notices. Write to us to discuss what works best for your business.
