Quick answer: Malaysian businesses can comply with e-Invoice rules either manually through LHDN’s free MyInvois Portal, or through accounting software connected via API or Peppol. The right choice usually comes down to transaction volume and how much manual data entry your business can realistically absorb.
Option 1: LHDN's MyInvois Portal

The MyInvois Portal is LHDN’s own web-based system, and it’s free to use. You don’t need a digital certificate to issue e-invoices through it, since LHDN handles the signing on the backend. It supports batch upload of up to 100 documents per file, with a limit of 1,000 draft documents at a time, and it’s also the only channel with a built-in print function for physical copies.For a business with a modest number of transactions a month, this is often a perfectly workable option. The trade-off is that it’s manual: someone still has to enter or upload the relevant details for each invoice.
Option 2: Accounting Software With API or Peppol Integration
For businesses issuing a higher volume of invoices, connecting an accounting or ERP system directly to LHDN via API removes most of the manual entry. Malaysia’s e-Invoice system also runs on Peppol, using a localised format called PINT-MY, which requires a Malaysia Peppol ID to transact. This is generally the route larger or higher-volume businesses take, since it lets e-invoices generate automatically as part of the normal sales process rather than as a separate step.
How to Decide Between the Two
There isn’t a single right answer here, it depends on your business:
- Transaction volume. A handful of invoices a week rarely justifies the cost of software integration. Dozens a day usually does.
- Existing accounting software. If your current system already supports e-Invoice integration, the incremental cost of turning it on may be small.
- In-house admin capacity. Manual entry needs someone with the time and attention to do it consistently, every month, without gaps.
- Budget for software or middleware. API and Peppol integration usually come with a subscription or setup cost that should be weighed against the time it saves.
What Happens If You Choose Wrong at First
This isn’t a permanent decision. Plenty of businesses start on the MyInvois Portal while transaction volumes are manageable, then move to software integration once volume grows to the point where manual entry becomes a bottleneck. There’s no compliance penalty for starting manual and switching later, as long as you’re meeting your submission obligations along the way.
How SASCO Can Help
If you’re not sure whether your current transaction volume justifies software integration, or you’d rather have someone else manage the MyInvois Portal submissions altogether, our accounting and compliance services can take this off your plate, whichever route makes more sense for your business.
