MyInvois e-Invoicing for Malaysian Businesses

What the MyInvois mandate requires

LHDN's e-Invoice regime is a phased, mandatory rollout covering invoices, credit notes, debit notes, and refund notes for B2B, B2G, and B2C transactions in Malaysia. Issuers transmit each document to MyInvois, LHDN validates the payload, and a Unique Identifier Number (UIN) and validation QR code are returned and shared with the buyer. Self-billed e-invoices are required in defined scenarios such as foreign-supplier transactions and certain agent/agency arrangements.

• Phase 1: taxpayers with annual turnover above RM100 million began 1 August 2024.
• Phase 2: turnover above RM25 million up to RM100 million began 1 January 2025.
• Phase 3: remaining taxpayers, staged through 2025-2026 (verify current LHDN dates before relying on them).
• In-scope documents: invoices, credit notes, debit notes, refund notes, and self-billed e-invoices.
• Consolidated e-invoices apply where individual B2C documents are aggregated under LHDN rules.

How POSMena handles MyInvois compliance

POSMena's Malaysia posture is MyInvois-ready. Each transaction is captured at point of sale or pulled from a connected channel, transformed into the LHDN-defined JSON/XML schema, digitally signed, and submitted to the MyInvois API. The returned UIN and QR code are stored on the document and printed or rendered on the buyer copy.

1. 1.Schema generation

   Sales, refunds, and adjustments are mapped into the LHDN-defined JSON/XML schema with the required tax, party, and line-item fields populated from POSMena's catalog and customer records.

2. 2.MyInvois API submission

   Documents are signed and transmitted to MyInvois through the LHDN API. Submission status, validation errors, and retries are tracked per document.

3. 3.UIN and QR capture

   POSMena retrieves and stores the LHDN Unique Identifier Number (UIN) and validation QR code on every issued document, so each invoice carries proof of LHDN validation.

4. 4.Self-billed and consolidated flows

   POSMena supports self-billed e-invoice scenarios required by LHDN under MyInvois, and handles consolidated e-invoice flows for in-scope B2C aggregation.

5. 5.Archive and retrieval

   POSMena archives validated e-invoices for the retention period required by Malaysian tax law (verify the current retention rule before citing), with searchable lookup by UIN, buyer, or date range.

Compliance posture and truth bar

POSMena describes itself as MyInvois-ready, aligned with the LHDN e-Invoice specifications, and preparing for further phase changes as LHDN publishes them. LHDN does not currently issue a public vendor certification logo for MyInvois, so POSMena does not claim to be 'LHDN-certified' or 'endorsed by MyInvois'.

• MyInvois-ready: generates LHDN-defined JSON/XML and submits via the MyInvois API.
• Aligned with LHDN e-Invoice guidelines for invoices, credit notes, debit notes, refund notes, and self-billed e-invoices.
• Preparing for upcoming Phase 3 thresholds and any LHDN-published vendor listings.
• Invoices issued in MYR with English and Bahasa Malaysia document layouts.

Connected ERPs, accounting tools, and sales channels

POSMena can act as the MyInvois submission layer in front of the accounting and commerce stack a Malaysian business already runs, so the existing system of record stays in place and only the LHDN-bound flow is added.

• Local accounting: SQL Account, AutoCount, Million.
• Cloud accounting: Xero MY, QuickBooks.
• Marketplaces and storefronts: Shopify, Lazada, Shopee, TikTok Shop.
• POS data flows into the same MyInvois submission pipeline as online orders, so B2C consolidation rules apply uniformly.
