1. Invoice Created in ERP

Transaction initiated in the source system (ERP, POS, etc.)

2. Tax Determination

  • Auto-classifies goods/services (HSN/SAC)
  • Applies correct GST type (CGST/SGST/IGST)
  • Handles reverse charge, exemptions, TDS/TCS logic

3. e-Invoice Generation (via IRP)

  • Invoice details pushed to Govt. portal (IRP)
  • IRN and QR code fetched and embedded
  • GSTR-1 auto-updated

4. e-Way Bill Generation

  • If applicable, e-Way Bill auto-generated via NIC portal
  • Merged with e-invoice (for transportation compliance)

5. Invoice Sharing with Buyer

  • Legally valid invoice sent with IRN & e-Way Bill reference
  • Buyer system can auto-validate and post

6. GST Return Preparation

  • GSTR-1 pre-filled from invoice data
  • Reconciliation-ready GSTR-2A/2B mapped for ITC validation

7. Intelligent Matching & IMS Actions

  • Match vendor invoices, flag mismatches
  • Take action on ITC eligibility or reversal (IMS engine)

8. Return Filing & Tax Payment

  • File GSTR-1, 3B, 9/9C, and other forms via portal/API
  • Track liabilities, ITC, and cash ledger balances

9. Audit-Ready Logs & MIS

  • Dashboards, logs, and audit trails maintained
  • Data archived for compliance, notices, or future audits

Without tax determination, you risk misclassification, incorrect GST rates, and errors in returns, leading to penalties, denied ITC, or audit red flags.
