Debit Note in Sales Invoice & Rate Diff & directly calculate GST ON that

Currently, there is no "Debit Note" feature available in the Sales Invoice module. When we issue an invoice with an incorrect/lower rate and later realize we need to adjust it upward, we cannot directly correct this in the system. This creates the following issues:

• No option to add a debit note in the sales invoice header • Cannot capture rate increases without creating a new invoice or using workarounds • Manual entries are error-prone and not audit-friendly

PROPOSED SOLUTION:

Implement a Debit Note feature in Sales Invoice that allows:

1. Add "Debit Note" option directly in the sales invoice header/creation screen

2. Simplified data entry - Allow users to enter ONLY the rate difference amount WITHOUT mandatory item description or quantity fields

3. Direct GST Calculation - System should automatically calculate GST on the entered rate difference amount

4. Display formula: Rate Difference Amount + (Rate Difference × GST Rate%) = Total Amount

5. Generate debit note with proper reference and link to original invoice

EXAMPLE USE CASE:

Original Invoice: Issued at ₹1000/unit Correction Needed: Should have been ₹1100/unit Rate Difference: ₹100 per unit

With this feature, we should be able to: → Create debit note entry → Enter rate difference: ₹100 (or total difference amount) → System auto-calculates GST (e.g., 18% on ₹100 = ₹18) → Display: Rate Difference + GST = Total Debit Note Amount → Link to original invoice for audit trail

BUSINESS BENEFITS:

✓ Saves time - No need for manual workarounds ✓ Reduces errors - Automatic GST calculation ensures accuracy ✓ Compliance ready - Proper documentation for audits ✓ User-friendly - Simplified entry for a common business scenario ✓ Professional - Maintains clean audit trail and invoice corrections

PRIORITY:

This is a HIGH PRIORITY feature as it addresses a common business requirement in sales operations. We request this to be incorporated at the earliest opportunity.

TECHNICAL NOTES:

When Debit Note is selected: • Display simplified form with "Rate Difference Amount" field • Auto-populate GST slab from original invoice settings • Calculate: GST Amount = (Rate Difference × GST Rate) / 100 • Show: Net Amount + GST = Total Payable • Generate unique debit note reference number • Create audit link to original invoice

Thank you for considering this important feature request. Please incorporate this at the earliest in your product roadmap.
