An invoicing system built for stock sales misses other income

Malaysia's e-invoicing rollout is no longer a pilot. The tax authority has now received over 2.09 billion e-invoices from more than 269,000 taxpayers (The Star). At that scale, the system your business uses for invoicing is not being tested anymore. It is in daily use, and its gaps are now visible to the authority checking it, not just to you.

Mistakes here come up often enough that the tax authority has flagged them directly. Some businesses issue self-billed e-invoices for suppliers who are not required to adopt e-invoicing at all, since this facility applies only to specific transactions under the guidelines, and confusion about it is common (The Star). Other businesses handle their stock sales correctly and stop there, missing other taxable activity such as selling a business asset or earning rental income (The Star).

What this has to do with the software you buy

Neither mistake is a software fault. It is a scope gap, set at the point the system was commissioned. If you described only your main sales process when the system was built or configured, that is the only process it covers. Rental income, asset disposals and self-billing for exempt suppliers often sit outside the original brief, not because they are difficult to add, but because nobody wrote them into the scope in the first place.

Before you sign off on the next invoicing system

List every category of income your business books across a year, not only the obvious one. Then ask the vendor to confirm, in writing, which categories the system issues e-invoices for and which it does not. Treat anything missing as a scope decision, not an oversight to fix later.

If funding is the concern holding you back, the 2027 national budget includes funding for digitalisation and automation projects aimed at small and medium enterprises (BERNAMA). That is national policy support, not a quote for your business. What it signals is that correcting a narrow invoicing scope counts as recognised, fundable work, not an extra.

There is a second scope question worth raising while you are at it, separate from tax compliance. The government has said it will review a competition regulator's findings on digital platforms charging high commissions, imposing restrictive contract terms and controlling user data in ways that disadvantage local businesses (The Star). If your invoicing or sales data sits inside a platform you do not control, ask who owns that data and what it costs to move it, before you sign anything.

At Yunaris, every engagement is scoped and quoted on its own, and invoicing systems are no exception. The lesson from the current rollout is not that e-invoicing is complicated. It is that a system only covers what it was told to cover, and deciding what that includes is the owner's job, not a guess left to the vendor.
