What Is MyInvois?

More Than Just a Digital Invoice

E-invoicing in Malaysia is a government-mandated transition from paper or PDF invoices to a structured, machine-readable format that LHDN validates in near real-time through the MyInvois platform.

Machine-verifiable records — every invoice carries a UIN and QR code for instant authentication.

Cleaner audit trails — significantly reduced manual errors and faster reconciliations.

Smoother SST reporting — validated invoice data feeds directly into tax submissions.

Faster payment cycles — validated, buyer-accessible invoices reduce disputes and delays.

MyInvois Requirements

What a Valid Malaysian E-Invoice Must Include

LHDN requires structured invoice data for every MyInvois submission. Ensure your invoices contain all the mandatory elements below.

Field 01

Seller Details

Business name, company registration number, registered address, and Tax Identification Number (TIN).

Field 02

Buyer Details

Buyer name, registration or identity number (where applicable), mailing address, and TIN if required.

Field 03

Invoice Number & Date

A unique, sequential invoice number and the exact date of issuance — both mandatory for traceability.

Field 04

Line Item Details

Description of goods or services, quantity, unit price, and any applicable discounts per line item.

Field 05

Total & Tax Breakdown

Total amount and SST breakdown clearly stated in Malaysian Ringgit (MYR), itemised where applicable.

Field 06

QR Code & UIN

A LHDN-issued Unique Identifier Number (UIN) and QR code for buyer verification and authenticity.

Important: The MyInvois portal requires up to 55 fields for a complete manual submission. The six fields above are the core essentials — a compliance expert can map your existing invoice templates to all required fields quickly and accurately.
Step-By-Step Process

How the MyInvois Process Works

Three streamlined steps take your invoice from creation to validated, buyer-ready status — all in near real-time.

1

Generate & Submit

Create your e-invoice in compatible accounting software or directly in the MyInvois portal. Submit via the portal (manual) or through an API connection (automated). The right method depends on your transaction volume and system setup.

Portal or API
2

IRBM Validation & UIN

LHDN's IRBM platform validates your e-invoice in near real-time, checking all required data fields. On approval, a Unique Identifier Number (UIN) is issued and embedded in the invoice record permanently.

Near Real-Time
3

Share & Store

Share the validated e-invoice — complete with QR code and UIN — with your buyer. Both parties must retain a copy. A 72-hour window allows for cancellation or buyer-requested rejection if needed.

Common Questions

Frequently Asked Questions About Malaysia E-Invoicing

Straight answers to the questions Malaysian business owners ask most about the MyInvois mandate.

What is e-invoicing in Malaysia?
E-invoicing in Malaysia is a government initiative requiring businesses to transition from traditional paper or PDF invoices to a structured, machine-readable digital format. The system is managed by LHDN (Inland Revenue Board of Malaysia) and operates through the MyInvois platform to improve tax compliance, reduce manual errors, and streamline audits.
Who must comply with e-invoicing?
Compliance is phased based on annual turnover. As of 1 January 2026, businesses with annual revenue between RM1M – RM5M are required to comply. Businesses below RM1 million are currently exempt, though this may change. Always verify your specific obligations against the latest LHDN guidelines.
Can my current accounting software connect to MyInvois?
Most modern accounting software (AutoCount, QuickBooks, Xero, etc.) supports direct API integration with MyInvois. If your software does not support API, middleware connectors can automate submissions on your behalf — though middleware solutions typically involve higher ongoing costs. A professional assessment will identify the most cost-effective route for your setup.
What happens if an e-invoice is rejected?
IRBM returns validation feedback in near real-time. After an e-invoice is issued, there is a 72-hour window during which the buyer can request rejection and the supplier can cancel. Having a clear correction workflow ensures rejected invoices are resolved quickly and re-submitted without compliance gaps.
Does e-invoicing change how I calculate SST?
No. E-invoicing standardises how invoices are submitted and validated — it does not alter the underlying SST calculation rules. You still calculate SST according to existing law. What e-invoicing does is make your SST reporting more accurate, audit-ready, and easier to verify.
How long must I keep e-invoice records?
Per LHDN retention requirements, businesses are generally required to retain tax records — including validated e-invoices — for up to 7 years. Use an accounting platform that allows secure export and archiving of all validated invoice data for this purpose.
How much does e-invoicing implementation cost?
Costs vary by scope and systems involved. A basic portal-only setup typically starts from MYR 100, while a basic API integration begins around MYR 300. Complex or legacy system implementations will cost significantly more. A tailored quote after a free consultation will give you a precise, fixed-price estimate.
Is MyInvois e-invoicing secure?
Yes. MyInvois uses standardised data formats and is processed through a secure government platform managed by LHDN/IRBM, which ensures data integrity and confidentiality. For API integrations, the security also depends on your software's connection protocols — a reputable implementation partner will ensure these are properly configured.
What is a UIN and why does it matter?
A Unique Identifier Number (UIN) is issued by IRBM upon successful validation of an e-invoice. It makes the invoice machine-verifiable: anyone with the QR code or UIN can confirm the invoice was legitimately validated by LHDN, preventing invoice fraud and simplifying audits for both sellers and buyers.
Does e-invoicing apply to B2C (retail) transactions?
MyInvois applies broadly to commercial transactions. While B2C rules may have specific provisions (e.g., consolidated invoices for retail), most businesses in scope must issue validated e-invoices across all taxable transactions. Review the latest LHDN FAQs or consult a compliance expert to confirm how B2C rules apply to your specific industry.
