How to use

  1. Purchase Register: an Excel/CSV with columns for Supplier GSTIN, Invoice No., Taxable Value and tax (IGST, CGST, SGST, Cess).
  2. GSTR-2B: download the 2B for the period from the GST portal (the B2B sheet of the Excel works directly).
  3. The tool auto-detects the columns — check the mapping shown under each file and correct any if needed, then press Reconcile.

Invoices are matched on supplier GSTIN + invoice number (ignoring spacing and punctuation). Tax is compared within the tolerance you set.
