As Malaysia embraces digital transformation in taxation, businesses must prepare to comply with the IRBM e-Invoicing requirements. The Inland Revenue Board of Malaysia (IRBM) has mandated that e-invoicing in Malaysia will be progressively implemented starting 1 August 2024, with full adoption expected by 2027. This initiative aims to improve tax transparency, reduce fraud, and streamline tax reporting. For businesses, it brings both regulatory challenges and opportunities for operational modernization. This article provides a complete checklist to help Malaysian businesses meet all technical, procedural, and compliance obligations for e-invoicing. Whether you’re an SME or a large enterprise, early preparation will ensure a smoother implementation that aligns with IRBM e-Invoicing guidelines.
Understanding Who Needs to Comply with IRBM e-Invoicing
Requirement Checklist
- Confirm Applicability: Check if your business falls under the IRBM e-Invoicing mandate and whether any exemptions or sector-specific rules apply.
- Identify Your Phase: Determine your compliance start date based on your annual revenue tier and IRBM’s phased rollout schedule.
- Define Implementation Needs: Understand what your business specifically requires to support e-Invoicing—from tools to resources.
- Invoice Volume Assessment: Evaluate how many invoices your business issues monthly or annually to gauge system and model suitability.
- Know Your Transaction Types: Classify your invoice transactions as B2B, B2C, B2G, or self-billed, since each may involve different processing needs.
- Check Industry Requirements: Review if your industry (e.g., healthcare, construction, telecom, e-commerce, petroleum) has specific compliance rules under IRBM guidelines.

Choosing the Right E-Invoicing Model: MyInvois Portal, API Integration, or Middleware Solution
IRBM officially provides two e-Invoicing submission methods: the MyInvois Portal and API Integration. However, many businesses adopt a third-party middleware solution like JomeInvoice to simplify and automate compliance, especially when existing systems aren’t ready for direct API integration.
- Option 1: MyInvois Portal (manual entry) – Ideal for small businesses with low invoice volume and simple workflows. Invoices are uploaded manually via a web interface.
- Best for low-volume invoice businesses or SMEs.
- Suitable if you don’t have an ERP or integrated billing system.
- Option 2: API Integration – Best for medium to large businesses needing automation. It connects directly to ERP or billing systems for real-time invoice submission and validation.
- Ideal for businesses with high transaction volumes or multiple systems.
- Recommended for businesses using custom ERP, POS systems, or requiring automation.
- Supports real-time validation and bulk submission of e-Invoices.
- Using Middleware Solutions (JomeInvoice) – a flexible option for businesses with mixed systems. They bridge existing platforms with IRBM, minimizing system changes and easing compliance.
- Acts as a flexible bridge between your current systems and IRBM’s infrastructure.
- Allows businesses to comply without overhauling existing ERP or invoicing software.
- Suitable for companies with multiple systems or fragmented workflows across departments.
- Ideal for both SMEs and large enterprises looking for easier e-Invoicing implementation with minimal disruption.
If you’re unsure, consider consulting with e-Invoicing experts from Jomeinvoice for professional guidance. For businesses choosing API integration, it’s advisable to work with a trusted e-Invoice solution provider to ensure smooth and compliant implementation.
Pre-Implementation Readiness: Internal Assessment
- Evaluate Business Operations
Assess your invoice volume, transaction types (B2B, B2C, B2G, self-billed), and the number of branches or sales channels generating invoices. - Review System Compatibility
Check whether your current billing or ERP system supports required formats such as XML or JSON, especially for API integration. - Verify Data Field Coverage
Ensure your invoicing system can capture all 55 mandatory data fields outlined by IRBM, including taxpayer details, item descriptions, invoice dates, and tax breakdowns. - Obtain a Digital Certificate
Apply for a digital certificate for signing e-Invoices. This is essential for validating authenticity and is a mandatory compliance requirement.
Technical & Software Configuration
Aligning your systems with IRBM e-Invoicing guidelines is essential for successful implementation. If you’re still using spreadsheets, legacy software, or basic accounting tools, consider adopting middleware or cloud-based e-Invoicing platforms to bridge the compliance gap.
Ensure your billing system can:
- Create invoices in XML or JSON format
- Embed QR codes for B2C transactions
- Apply a valid digital signature e-Invoice using an IRBM-issued certificate
- Transmit invoices to IRBM via the MyInvois API or manual upload
Your system must also support the generation of consolidated monthly invoices for B2C sales, especially if you operate in retail, F&B, or e-commerce. In addition, implement secure storage with role-based access controls to retain submitted invoices for at least seven years, as mandated.
Workflow Controls & Internal Governance
Set up clear internal controls to manage e-Invoicing processes. Assign authorized staff to handle invoice approvals, rejections, and cancellations—ensuring these actions happen within the same calendar month.
Establish SOPs for managing disputes and issuing credit or debit notes when needed. Ensure stable internet access at all billing points to prevent disruptions, especially for businesses with multiple branches or retail counters.
Checklist:
- Assign authorized staff to issue, approve, reject, and cancel e-Invoices.
- Create clear SOPs for cancellation and rejection—these must be done within the same calendar month.
- Handle disputed invoices promptly through credit/debit note issuance.
- Ensure stable internet connectivity across all branches and billing counters.
Employee Training & Capacity Building
Train your finance, operations, and IT teams to understand their roles in the e-Invoicing process. Provide clear guides, demos, and practical exercises to help them manage invoice generation, validation, and submission.
Include training on handling rejection errors, tax code classification, and using the MyInvois Portal or ERP-integrated system. Well-prepared staff reduce compliance risks and ensure a smooth implementation.
Checklist:
- Conduct structured training for finance, operations, and IT teams.
- Provide documentation, demos, and hands-on sessions for using the MyInvois Portal or ERP integration.
- Train staff to handle rejection errors, assign correct LHDN tax codes, and follow compliance procedures.
- Prepare employees for go-live to avoid post-launch issues.
Testing, Quality Assurance & Go-Live Preparation
Testing is a critical phase of your e-Invoicing checklist. Simulate invoice submissions in a User Acceptance Testing (UAT) environment to validate data field mapping, XML/JSON formatting, digital signing, and end-to-end submission flow to IRBM.
You should:
- Run load tests for bulk invoice submissions
- Validate error-handling workflows
- Ensure system integration with MyInvois returns timely feedback
- Review audit logs and digital signatures for integrity
Once testing is complete, roll out the system in phases—starting with a pilot group or department before scaling organization-wide.
Industry-Specific Considerations
Each industry may have unique e-Invoicing needs under IRBM guidelines. Retailers should enable QR-code receipts for customer access. Manufacturers and logistics providers must streamline bulk uploads and invoice consolidation.
For sectors like professional services and education, ensure SST exemptions and tax rules are correctly applied in e-Invoice data. Align workflows with IRBM requirements to avoid errors and ensure full compliance.
- Retailers: Use QR-code-enabled receipts for B2C invoices.
- Manufacturers/Logistics: Implement batch uploads and invoice consolidation.
- Service/Education sectors: Apply correct SST exemptions and ensure proper data field alignment.
- Tailor your e-invoicing workflows to meet industry-specific IRBM requirements.
Post-Implementation Monitoring & IRBM Updates
Compliance continues after go-live. Monitor system performance, check for rejected invoices, and ensure your digital certificates stay valid.
Assign a team or vendor to track IRBM updates, apply tax rule changes, and install software patches. Treat e-Invoicing as an ongoing process to stay compliant and avoid disruptions.
Checklist:
- Regularly track system performance and rejected invoices.
- Ensure digital certificates are active and valid.
- Assign a compliance lead or vendor partner to monitor IRBM updates.
- Review audit logs, apply software patches, and stay aligned with new guidelines.
