e-Invoicing in Malaysia: a plain-language guide for SMEs
What MyInvois actually does, what changes in your day-to-day invoicing, and the handful of details — the 72-hour window, consolidated e-invoices — that catch businesses out.
e-Invoicing is LHDN's move from invoices as documents you send to invoices as data it validates. It is being rolled out in phases by annual turnover, so the date it applies to you depends on the size of your business — LHDN publishes the current timeline and any exemptions on its e-Invoice pages, and that is the source to check.
Whatever your date, the mechanics are the same.
What happens to an invoice
- You issue the invoice in a structured format and submit it to LHDN's MyInvois system.
- MyInvois validates it and returns a unique identifier, with a QR code that lets anyone check the invoice is genuine.
- The validated e-invoice is shared with your buyer.
The invoice you send your customer is, in effect, the validated one. An invoice that has not been validated is not an e-invoice.
The 72-hour window
After validation there is a 72-hour window in which the buyer can reject the e-invoice, or you can cancel it. Once the window closes, a correction is no longer a cancellation — it needs a credit note, debit note or refund note issued as its own e-invoice. That is why it pays to catch mistakes before submission, not after.
Details that catch businesses out
- Buyer details. A business buyer's Tax Identification Number (TIN) and registration details are required. For buyers who are members of the public without a TIN, LHDN provides a general TIN to use instead.
- Consolidated e-invoices. Sales to consumers who do not ask for an e-invoice can be combined into one consolidated e-invoice per month, submitted shortly after month-end.
- Self-billed e-invoices. In some situations — buying from a foreign supplier, for example — the buyer issues the e-invoice rather than the seller.
What it changes for you
Mostly, it rewards clean data. If your customer and supplier records are complete — names, TINs, registration numbers, addresses — e-invoicing is a background step. If they are not, every invoice becomes a small investigation.
How Fortura handles it
Fortura builds the e-invoice from the invoice you already raised, carrying buyer details from your ledger rather than asking you to retype them. It is checked against the rules before it is submitted, so a missing field is something you fix in a minute, and the submission status sits on the invoice itself. e-Invoicing is included in every Fortura plan.
