  • Map the issue to the correct GSTIN, return period, registration type and place-of-supply facts before choosing the filing or advisory route.
  • Reconcile outward supplies, purchase register, GSTR-2B/2A, e-invoice or e-way bill data where relevant.
  • Check if the work involves registration, amendment, cancellation, ITC, RCM, composition, annual return, refund or notice response.
  • Keep portal access, notices, invoices, ledgers and prior returns ready so the expert can quote precisely.
