The Malaysian government is undergoing a major digital transformation—and businesses are right at the heart of it. If you’re a freelancer, SME owner, or managing accounts for your company, you’ve probably come across the term “MyInvois.”

But what exactly is it? Why is it important? And more importantly—how do you start using it?

This guide answers all that and more, with a clear walk-through designed to help you understand and confidently use MyInvois, Malaysia’s official e-invoice platform by LHDN (Lembaga Hasil Dalam Negeri).

Who Should Use MyInvois?

MyInvois is built for Malaysian taxpayers who do not use sophisticated ERP (Enterprise Resource Planning) systems. It’s ideal for:

  • Freelancers and self-employed professionals
  • Traditional brick-and-mortar businesses
  • Small to mid-sized enterprises (SMEs)
  • Startups or home-based sellers
  • Anyone running a business without integrated accounting software

If you’re not already integrated with a larger accounting or ERP system, this is your ticket to staying compliant—without breaking the bank.

Key Features of the MyInvois Portal

The MyInvois Portal is a cloud-based platform developed by LHDN to help Malaysian businesses generate and manage e-invoices. Here’s what it offers:

Core Features

  • Invoice Creation: Generate e-invoices for business transactions
  • Document Management: Store invoices securely in your portal.
  • User Dashboard: Get insights into invoice status and summaries.
  • Secure Login: Access the portal via your MyTax credentials.
  • 24/7 Availability: Access anywhere, anytime.

💡 Bonus tip: For added support or enhanced reporting, consider tools like Assist.Biz that integrate with MyInvois.

Live vs. Testing Environment: Know the Difference

LHDN offers two environments to help users familiarize themselves with e-invoicing:

Environment

Purpose

Sandbox (Testing)

Try out invoicing in a risk-free space (recommended first)

Production (Live)

Real-time, legally validated invoices with tax authority

Most businesses start in the sandbox before going live. The LHDN strongly recommends testing to avoid mistakes once you’re in production mode.
