The words you will meet, in plain language.

LHDN / IRBM
The Inland Revenue Board of Malaysia, the tax authority that runs e-Invoicing.
MyInvois
LHDN’s e-Invoicing system, a free web portal for issuing e-Invoices, plus an API for high-volume integration.
Clearance
The model where the tax authority validates each invoice in near real time, before it is shared with the buyer.
Validation
LHDN’s check of a submitted e-Invoice’s structure and fields. On success it returns a validated e-Invoice.
Unique identifier
The reference LHDN assigns to a validated e-Invoice; it, with the QR code, marks the official record.
QR code
Embedded on the validated e-Invoice; it links back to the record on MyInvois so anyone can confirm it is genuine.
TIN
Tax Identification Number, the party identifier used on e-Invoices for both supplier and, where required, buyer.
Consolidated e-Invoice
A single e-Invoice aggregating many small B2C sales for a period, allowed where buyers do not need individual e-Invoices.
Self-billed e-Invoice
An e-Invoice the buyer issues on the supplier’s behalf in specific cases (e.g. foreign suppliers).
Cancellation / rejection window
A short window (72 hours) after validation in which the supplier may cancel, or the buyer may reject, an e-Invoice.
Always confirm with the source. Rules and dates change. This page reflects the position as of early 2026; verify current requirements on the LHDN e-Invoice site or the MyInvois portal before you act.
