Credit note — reduces what the customer owes against a previously-approved invoice.
A credit note (type 02) is how you correct an over-charge, apply a discount after the fact, or accept a return. LHDN tracks every credit note against the UUID of the original invoice it modifies — the parent reference is mandatory, not optional. Once the credit note is approved, the customer's net balance is the original invoice total minus the credit.
Four common scenarios.
- 01Post-issue discount — you offered a price reduction after the invoice was already approved by LHDN.
- 02Returned goods — the customer sent items back; you reduce their liability for the returned quantity.
- 03Billing error correction — you over-charged on a line item and need to credit back the difference.
- 04Volume rebate — end-of-period rebate applied retroactively against earlier invoices.
What this document type carries that a generic invoice doesn't.
- Original invoice reference — LHDN UUID of the parent type-01 document.
- Reason code — LHDN expects a structured reason for the credit, not free text.
- Credit amount — line-item or full-document credit, with the right sign convention.
- Same supplier + customer parties as the parent invoice (no party flip).
Same pipeline as every other type.
The bridge stores the LHDN UUID of every approved invoice. When you issue a credit note in the dashboard, the parent reference is filled in automatically from the catalog. CSV uploads carry the parent UUID as a column; the bridge validates the link exists before submitting so LHDN doesn't reject for a dangling reference.
