What ‘Validated’ really means
Validated is LHDN's acceptance status — and there are a few states it can transition into. Here's the map.
Validated
Your invoice has been signed by you, accepted by LHDN, and assigned a UUID. The buyer can verify it independently from MyInvois. This is the happy path.
Cancelled (within 72 hours)
LHDN allows you to cancel a validated invoice within 72 hours of validation. After that window, you cannot cancel — you can only issue a credit note. ZeroKey lets you cancel from the invoice page with one click.
Rejected by buyer
Your buyer can reject an invoice within the 72-hour window. The invoice transitions to ‘rejected’ and is no longer a valid e-invoice. Issue a credit note or correct the invoice and resubmit.
Failed validation
If LHDN rejects the submission, ZeroKey shows the validation error in plain English and links to a fix. Common causes: wrong TIN format, missing MSIC code, totals that don't add up.
