There are actually two different "QR code" ideas that show up in e-Invoice conversations in Malaysia, and mixing them up causes confusion. Here's both, explained clearly.
Every e-Invoice validated through MyInvois includes a QR code as part of the document. Scanning it takes you to a page on LHDN's system confirming the invoice's validation status and key details (amount, date, parties involved). This exists so anyone receiving an e-Invoice — a customer, an auditor, another business — can independently confirm it's real and was actually processed by LHDN, not just printed to look official.
Separately, some billing software — including TxBilling's QR After-Sale e-Invoice Conversion feature — lets a business print a QR code on a normal receipt at checkout. This QR code is not LHDN's validation QR; it's a business-side convenience feature. A customer who realises after leaving the store that they need a proper e-Invoice (for a company claim, for example) scans it to self-serve one, without the counter staff needing to stop and manually process it.
| LHDN validation QR | After-sale conversion QR | |
|---|---|---|
| Appears on | The validated e-Invoice document itself | A regular receipt, before any e-Invoice is issued |
| Purpose | Verify the e-Invoice is genuine | Let the customer request an e-Invoice later |
| Who provides it | LHDN MyInvois (mandatory, standard format) | The business's own billing software (optional convenience feature) |
It links to LHDN's MyInvois portal, allowing verification that the invoice was genuinely validated and checking its key details.
Yes — some businesses print a separate QR code on the sales receipt that lets the customer request/generate an e-Invoice afterward. This is a business convenience feature, distinct from LHDN's own validation QR code.
No — it's an optional feature some billing software offers to make e-Invoice compliance easier for high-volume, walk-in businesses like retail and F&B.
