Processing Engine

Smart Deduction & State POS Mapping

Our core parsing engine cleans column names, handles missing values, and calculates net taxable turnover.

  • Returns Deduction: Net Sales = Gross Sales - Customer Returns
  • POS State Code Normalization: Maps state names (e.g., "UP" ➔ 09-Uttar Pradesh)
  • Tax Split: Segregates IGST, CGST, and SGST at 0%, 5%, 12%, 18%
