Managing E-invoice Failures

Fixing E-Invoice Failures: HSN Code & Tax Rule Issues​

Why E-Invoice Compliance Matters​

For merchants engaged in B2B transactions and cross-border trade, e-invoice generation is mandated by the Government of India. When tax rates, HSN codes, or their mapping are incorrect, e-invoice generation fails, creating significant business disruptions in processing orders.

Previously, merchants had to contact support teams to resolve these issues manually, causing delays in order fulfilment and customer satisfaction. Fynd Commerce now provides a self-service solution that lets you identify the errors, correct them, and retry e-invoice generation from the Order Management System, eliminating delays and dependency on support.

When You'll See This Screen​

The "Regenerate E-Invoice" screen appears when e-invoicing fails due to:

  • Missing or invalid HSN codes
  • Incorrect GST percentages
  • HS code and tax rate mapping is incorrect
  • Invalid tax calculations
  • Other reasons

Accessing the Interface to fix the issues​

  1. Navigate to the locked order in OMS

  2. Click Retry E-Invoice

  3. The screen will display the:

    • Shipment ID and error list summary
