A practical guide for businesses ready to integrate with MyInvois Portal — and how JomeInvoice removes the technical hassle by handling API integration, compliance logic, and invoice submission on your behalf. JomeInvoice provides a ready-built integration that handles API connectivity, LHDN compliance, invoice submission, and post-issuance workflows such as refunds and self-billing.
Malaysia’s e-Invoice mandate has made MyInvois integration a real operational requirement — not just a compliance checkbox.
For many businesses, the first question isn’t whether to comply, but:
“Do we really need to build a custom integration just to connect to MyInvois?”
The short answer: No.
In this guide, we’ll walk you through:
- What MyInvois Portal integration actually means
- Why building your own e-Invoice integration is costly and risky
- How businesses can integrate existing systems without internal development
- A practical, compliant alternative using JomeInvoice
What Does It Mean to Integrate with the MyInvois Portal?
Integrating with the MyInvois portal means your business system can:
- Automatically submit e-Invoices to LHDN
- Receive validation results (approved / rejected)
- Generate compliant documents (Invoice, Credit Note, Debit Note, Refund Note, Self-Billing)
- Store and track e-Invoice status for audit purposes
In practice, this usually involves:
- API connections to MyInvois
- Mapping your internal data to LHDN-required fields
- Handling errors, rejections, and spec updates
This is where complexity — and cost — starts to grow.
Why Many Businesses Avoid Building Their Own MyInvois Integration
On paper, building a direct MyInvois integration sounds straightforward. In reality, it comes with several hidden challenges.
1. High Development & Maintenance Cost
A custom e-Invoice integration requires:
- Backend developers
- API maintenance
- Continuous updates when LHDN changes formats or rules
For most SMEs, this becomes a long-term cost, not a one-off project.
2. Frequent LHDN Specification Updates
MyInvois technical specifications evolve.
Every update means:
- Code changes
- Retesting
- Risk of non-compliance if updates are missed
Businesses without a dedicated tech team often struggle to keep up.
3. Data Validation & Rejection Risks
Even small issues can cause invoice rejection:
- Incorrect tax codes
- Invalid TINs
- Incomplete mandatory fields
Handling these errors manually increases operational friction and delays invoicing.
4. Compliance Risk Is Still on You
When you build it yourself:
- Compliance responsibility stays internal
- Any mistake may result in penalties or audit exposure
For many businesses, this risk outweighs the perceived control of a custom build.
The Smarter Myinvois Integration Alternative: Use a Certified e-Invoicing Middleware
Instead of building from scratch, many Malaysian businesses are adopting an e-invoicing middleware approach.
An e-invoicing middleware platform:
- Connects your existing system to MyInvois
- Handles API complexity and updates
- Ensures ongoing LHDN compliance
This allows businesses to focus on operations — not technical maintenance.
