Malaysia e-Invoice

Purpose

See how Malaysia e-Invoice (LHDN MyInvois) works in KinraSoft, pick the right job, then open the matching topic. This page does not submit anything. It tells you who issues, when to submit, and which screen or Assistant chip to use.
KinraSoft keeps the books (invoice, cash sales, credit note) and, when you are ready, sends that document to MyInvois. A successful send does not change your document number. After IRBM validates, the document also gets a Unique Identifier (UUID) from MyInvois.

H2 — LHDN Client ID and company e-Invoice profile. First-time MyInvois: Client ID plus company TIN and MSIC.
H3 — Buyer and supplier TIN. Customer or supplier TIN, category, Search TIN, bill-to versus deliver-to.
H4 — Submit and check status. Submit one or many documents; listing; Valid or Invalid; cancel.
H5 — Consolidated e-Invoice. Month-end pack of leftover receipts. Not for related-company sales.
H6 — Self-billed e-Invoice. You issue the e-Invoice as the buyer.
H7 — Credit, debit, and refund notes after validation. After Valid: cancel versus credit note versus debit note versus refund note.
H8 — e-Invoice FAQ. e-Commerce, freelancers, QR, foreign TIN, related companies.

You sold goods or services. You (the supplier) issue. Sales Invoice, Cash Sales, credit note, debit note, or Refund → Submit E Invoice. See Submit and check status.
Many small walk-in receipts, no individual e-Invoice. You issue one consolidated e-Invoice. See Consolidated e-Invoice.
You must issue for the other party (agent, foreign supplier, commission, individual, and other IRBM self-bill cases). You issue as self-billed. See Self-billed e-Invoice.
A Malaysian supplier already issues their own e-Invoice to you. They issue. You receive it on E Invoice Listing (download). Do not self-bill unless IRBM allows that case. See e-Invoice FAQ.
e-Invoice applies to domestic and international transactions. All taxpayers in commercial activity in Malaysia must issue, on the phased IRBM timeline. No industry is exempted.
