About Our e-Invoice Middleware

What Is This e-Invoice Middleware?

Our e-Invoice middleware is a standard, ready-to-use software product designed specifically for Malaysian businesses that need to connect their overseas POS or ERP systems to LHDN MyInvois.

Unlike custom-built solutions that require months of development, this middleware is a production-ready system that can be deployed quickly and cost-effectively. It handles the technical complexity of LHDN MyInvois integration, allowing businesses to focus on their operations rather than compliance infrastructure.

The middleware supports multiple integration methods including API integration, CSV file upload, and FTP/SFTP automation. It processes invoices, consolidated invoices, credit notes, and debit notes according to LHDN MyInvois specifications.

What Is e-Invoice in Malaysia?

e-Invoice is a digital invoicing system mandated by LHDN (Lembaga Hasil Dalam Negeri Malaysia) to modernize tax administration and improve business transparency in Malaysia.

Unlike traditional paper or PDF invoices, e-Invoices are structured digital documents that must be validated and submitted to LHDN's MyInvois platform in real-time or near real-time. This system enables:

Automated tax reporting and compliance verification
Reduction of tax evasion and invoice fraud
Streamlined business-to-business (B2B) and business-to-consumer (B2C) transactions
Digital record-keeping for audit purposes

Every e-Invoice submitted to MyInvois receives a unique validation code, confirming its authenticity and compliance with LHDN requirements.

Malaysia e-Invoice Implementation Timeline

LHDN has implemented e-Invoice requirements in phases based on business size and annual revenue:

Phase 1 (August 2024): Companies with annual revenue exceeding RM100 million
Phase 2 (January 2025): Companies with annual revenue exceeding RM25 million
Phase 3 (July 2025): All other businesses, including SMEs

Businesses must ensure their systems can generate and submit e-Invoices before their applicable deadline. Non-compliance may result in penalties and operational disruptions.

Note: Timeline information is based on LHDN announcements as of the implementation date. Please visit the official LHDN e-Invoice portal for the latest updates and guidelines.

e-Invoice Technical Requirements

To comply with LHDN MyInvois requirements, businesses must ensure their invoicing systems can:

Data Requirements

Supplier and buyer information (TIN, registration details)
Invoice number, date, and currency
Line item details (description, quantity, unit price)
Tax calculations (SST, exemptions)
Payment terms and methods

Technical Capabilities

JSON or XML data formatting
API integration with LHDN MyInvois
Digital signature and authentication
Real-time or batch submission
Error handling and resubmission logic

The Challenge: Most overseas POS and ERP systems were not designed with Malaysia-specific e-Invoice requirements in mind. This is where middleware solutions become essential—they bridge the gap between your existing systems and LHDN MyInvois without requiring expensive system replacements or custom development.

For detailed technical specifications, refer to the LHDN MyInvois documentation and API guidelines.

Standard Product vs Custom e-Invoice Solutions

It's important to understand that this middleware is a standard product, not a custom development project. This distinction matters for deployment time, cost predictability, and ongoing support.

This Standard Middleware Is For:

SMEs using overseas POS or ERP systems
Businesses needing fast deployment (days, not months)
Standard invoice workflows and data structures
Predictable, subscription-based or one-time licensing costs

Xantec also provides custom e-Invoice and system integration services for businesses with specialized requirements. Custom solutions are appropriate when:

Your business has highly specialized workflows that don't fit standard patterns
You need deep integration with legacy or proprietary systems
Your data structures require extensive transformation logic
You're building a complex enterprise integration architecture

For most Malaysian SMEs, this standard middleware provides the right balance of functionality, cost, and deployment speed.

Support and Ongoing Maintenance

The middleware comes with comprehensive support and maintenance options designed for long-term reliability:

Subscription model: Includes ongoing updates, bug fixes, and technical support
One-time license with annual maintenance: For businesses preferring perpetual licensing
Optional customization: Integration enhancements and workflow adjustments available
Regular updates: Aligned with LHDN MyInvois API changes and improvements

Our support team understands the critical nature of e-Invoice compliance and provides responsive assistance to ensure your operations run smoothly.

Supporting Malaysia e-Invoice Requirements

This middleware is built based on LHDN MyInvois API documentation and is designed to support Malaysia e-Invoice submission workflows. It helps businesses prepare for and operate under Malaysian e-Invoice requirements by handling the technical integration between their existing systems and the LHDN MyInvois platform.

The system processes invoice data according to LHDN specifications, manages API authentication, handles error responses, and maintains submission logs for compliance tracking.

Important: This product is not affiliated with, endorsed by, or certified by LHDN (Lembaga Hasil Dalam Negeri Malaysia). It is an independent software solution developed to assist businesses with their e-Invoice compliance requirements.

Support for Malaysian business workflows and practices
