Cancel a document
Audience: All users (SME) Time: 1 minute
Made a mistake on a validated e-invoice? LHDN lets you cancel it within 72 hours of validation. After that window you must issue a credit note instead. envoice cancels straight from the document.
1. Open the document
Go to Documents and open the validated invoice you want to void. If it is still within 72 hours of validation, a Cancel document panel is shown with the time remaining.

2. Enter a reason and cancel
Type a short reason (at least 5 characters, e.g. "Issued in error"), then click Cancel document. envoice sends the cancellation to LHDN.
3. Done
The status changes to CANCELLED and the audit trail records who cancelled it and when. The document stays in your records for reference, marked cancelled.

Past 72 hours, the Cancel panel disappears. Reverse the invoice with a credit note instead , that is the LHDN-approved way to undo a validated invoice after the cancellation window closes.
