GST Invoicing in India – What Your Billing Software Must Do

If you run a business in India, your billing software must support GST compliance. Here’s what to look for.

GST-compliant invoice format

Invoices must include:

• GSTIN of supplier and recipient
• HSN/SAC codes
• Tax rates (CGST, SGST, IGST) and amounts
• Place of supply
• Invoice number and date in the required format

Good software generates invoices that meet these requirements by default.

E-invoicing and e-way bills

For applicable turnover, e-invoicing (IRP) and e-way bill integration are mandatory. Your software should support generating and tracking these without manual steps.

Returns and reporting

GSTR-1, GSTR-3B, and annual returns require consistent data. Your system should:

• Store all transaction data needed for returns
• Export or integrate with return-filing tools
• Provide clear reports for reconciliation

Inventory and credit notes

Inventory tracking and credit note handling should align with GST rules (reversal, adjustment). This keeps books and returns in sync.
