What this helps you do

Issue a GST debit note when the taxable value or GST rate on an already-issued tax invoice needs to increase.

Before you start

Use this only when an original tax invoice exists and the correction increases what was invoiced. A debit note becomes a permanent numbered document. It does not edit the order, collect money, change stock, or replace the original invoice.

Steps

  1. Open Orders and select the order.
  2. Open the original invoice action menu and select Issue debit note.
  3. Choose the Original tax invoice being corrected.
  4. For each affected invoice item, choose a Correction.
  5. Enter the fields for that correction and leave unaffected items as No adjustment.
  6. Enter a clear Reason of at least five characters.
  7. Check the estimated Debit note total.
  8. Select Issue debit note.
  9. Read the permanent-issue warning and confirm.
  10. Open the new document from the order and verify its number, items, GST, reason, and total.

Choose the correct correction

  • No adjustment: this invoice item is not part of the debit note.
  • Increase taxable value: add taxable value that should have appeared on the original item.
  • Correct GST rate upward: apply a higher correct GST rate to an affected part of the original taxable value. This choice appears only when that item can safely use it.

Fields for an increased taxable value

  • Quantity: quantity to which the additional value belongs. It accepts values from 0.001 to 10,000.
  • Additional taxable value: extra value before GST, not the new full item total.
  • Additional cess: extra cess for this correction. Enter zero when none applies.
  • GST remains: Upstorr keeps the original item’s GST rate for this type of correction. If the original line had no GST, this correction does not invent GST.

Fields for an upward GST correction

  • Taxable value affected: the part of the original taxable value that used the wrong rate. It cannot exceed that item’s original taxable value.
  • Correct GST rate: the higher correct rate. It must be above the original rate and cannot exceed 40%.

For example, if ₹1,000 of an item was invoiced at 5% but should have been 12%, choose Correct GST rate upward, enter ₹1,000 as the affected value, and 12 as the correct rate.

What happens next

Upstorr permanently issues a numbered debit note and adds it to the order’s documents. The original invoice stays unchanged so the records show both the original sale and its later upward correction.

Common problems

  • Issue debit note is missing: The order needs an issued original tax invoice, and a debit note may already exist for it.
  • An invoice says unavailable: Read its shown reason; Upstorr will not issue an unsafe duplicate or unsupported correction.
  • The total is zero: Choose at least one adjustment and enter positive valid values.
  • GST rate is rejected: It must be higher than the original rate and no more than 40%.
  • You need to reduce an invoice: A debit note is for an increase. Use the correct credit or return document flow for a reduction.
  • You need to collect the extra money: Do that separately. Issuing this document does not charge the customer.
