Step-by-Step Guide to Create e-Invoices via MyInvois Portal

Malaysia’s digital transformation in taxation has made e-invoicing an essential compliance requirement for businesses. The implementation of the MyInvois Portal by the Inland Revenue Board of Malaysia (LHDN/IRBM) simplifies the process of issuing, managing, and submitting e-invoices, particularly benefiting SMEs and companies without ERP or accounting systems.

The e-invoicing rollout is being done in phases, starting with larger businesses, while others can familiarize themselves with the process through the MyInvois Testing Environment (sandbox). Using this environment allows businesses to practice issuing e-invoices without affecting actual records, ensuring accuracy and reducing errors when transitioning to the live system. By following this guide, business owners can confidently navigate the MyInvois Portal and start issuing e-invoices in full compliance with Malaysian tax regulations.

What is the MyInvois Portal?

The MyInvois Portal is a free, comprehensive e-invoicing platform provided by the LHDN/IRBM to streamline invoice management for Malaysian businesses. It is part of Malaysia’s digital tax ecosystem, which integrates with the MyTax Portal.

Key Features of MyInvois Portal:

• Issuing e-invoices – Create standard invoices for products and services.
  
• Credit & Debit Notes – Manage adjustments, refunds, or additional charges.
  
• Self-Billed Invoices – Enable clients to generate invoices on behalf of the supplier.
  
• Real-Time Validation – Performs TIN/BRN checks to prevent submission errors.
  
• Document Management – Store, track, and retrieve issued e-invoices efficiently.

Device Compatibility:

The portal can be accessed via:

• Desktop browsers
• Android app
• iOS app

Benefits of Using the MyInvois Portal:

• Compliance: Aligns with Malaysian tax laws and Income Tax Act 1967.
  
• Error Reduction: Sandbox environment helps identify and correct mistakes before live submission.
  
• Efficiency: Streamlines invoicing tasks and reduces manual paperwork.
  
• Training: Employees can practice using the portal safely before mandatory adoption.

The MyInvois Testing Environment is particularly useful for businesses preparing for mandatory e-invoicing. By simulating real-world invoice issuance, businesses can familiarize themselves with the system, ensure accurate data entry, and reduce potential disruptions when the live system becomes mandatory.

Understanding the MyInvois Sandbox / Testing Environment

Before issuing official e-invoices in Malaysia, it is highly recommended for businesses to use the MyInvois Sandbox—a dedicated Testing Environment provided by the Inland Revenue Board (LHDN/IRBM). This simulated platform allows users to practice creating, submitting, and validating e-invoices without affecting real transactional data.

Purpose of the Sandbox

The sandbox serves as a safe space for businesses to explore all functionalities of the MyInvois Portal. Users can experiment with issuing invoices, credit notes, debit notes, refund notes, and self-billed invoices in a risk-free environment. This ensures familiarity with the portal before engaging with live transactions.

Access Link

Access the testing environment at: preprod-mytax.hasil.gov.my

This pre-production portal mirrors the live environment, allowing businesses to confidently test workflows and understand data entry requirements.

Advantages of Using the Sandbox

1. Training Employees: Staff can practice generating, submitting, and validating e-invoices without the pressure of affecting actual invoices.
   
2. Testing Processes: Businesses can simulate real-world invoicing scenarios to identify and fix potential issues before live submission.
   
3. Error Reduction: Familiarity with the portal reduces mistakes during actual issuance, ensuring smoother operations and compliance with LHDN regulations.
   

Recommendation

Start using the sandbox now even if you’re not yet mandated. Practice builds confidence and ensures a seamless transition. Regular practice ensures a seamless transition to mandatory e-invoicing, builds staff confidence, and minimizes operational disruptions when the system goes fully live.

By leveraging the MyInvois Sandbox, Malaysian businesses—especially SMEs and those without ERP/accounting systems—can prepare effectively for Malaysia’s phased e-invoicing implementation, reducing risk and ensuring compliance.

Tips for Businesses Using MyInvois Portal

Using the MyInvois Portal effectively can save time, reduce errors, and ensure compliance with Malaysia’s digital tax requirements. Here are essential tips for businesses:

1. Start with the Sandbox Environment Before Live Issuance

Before issuing official e-invoices, it’s highly recommended to practice in the MyInvois Sandbox (Testing Environment):

• Accessible at preprod-mytax.hasil.gov.my, the sandbox allows businesses to simulate real transactions without affecting live records.
  
• Employees can familiarize themselves with the platform, test invoice creation, and validate processes.
  
• This helps prevent costly errors during actual e-invoice submission.
  

2. Ensure TIN/BRN Validation to Avoid Errors

One of the most common issues when issuing e-invoices is incorrect Tax Identification Number (TIN) or Business Registration Number (BRN):

• Always validate buyer TIN/BRN in the MyInvois Portal before proceeding.
  
• Only validated IDs allow the invoice to be successfully submitted.
  
• Accurate validation ensures compliance with IRBM rules and avoids rejections or delays.
  

3. Consider ERP or Middleware Solutions for High-Volume Invoices

For businesses that issue large numbers of invoices monthly, manual entry can be time-consuming and prone to errors:

• Integrate your accounting system or ERP with e-invoice compliant middleware.
  
• Automation reduces manual data entry, speeds up invoice issuance, and improves record management.
  
• Middleware solutions can also handle bulk validations and submissions, making compliance effortless.
  

4. Train Staff on Step-by-Step Procedures to Minimize Mistakes

Even with automation, human errors can occur if staff are not familiar with the process:

• Run sandbox drills. Standardize SOPs for creation, taxes, submission, validation links, and cancellations.
  
• Walk employees through each step: creating invoices, adding line items, applying taxes, and submitting documents.
  
• Provide guidelines for handling errors, cancellations, and validation links.
  
• Well-trained staff ensures smooth operations and avoids compliance issues.
  

By following these tips, businesses can maximize efficiency, reduce errors, and confidently use the MyInvois Portal for seamless e-invoicing. Preparing early, validating data accurately, leveraging automation, and training staff are key steps for a successful transition to Malaysia’s mandatory e-invoicing system.

Conclusion

The MyInvois Portal is a vital tool for businesses in Malaysia, streamlining e-invoicing processes while ensuring compliance with the Inland Revenue Board (IRBM) regulations. By leveraging the portal, companies can efficiently generate, submit, and manage e-invoices, reducing errors and improving operational transparency.

Businesses are strongly encouraged to test e-invoice issuance in the sandbox environment before going live. This practice minimizes mistakes, ensures staff are familiar with the system, and guarantees smooth integration with existing accounting processes.

Adopting e-invoicing early not only simplifies compliance but also prepares businesses for Malaysia’s phased e-invoicing implementation, helping them transition seamlessly into a fully digital invoicing ecosystem.
