What Malaysian Businesses Still Get Wrong About e-Invoicing

Malaysia’s e-Invoicing journey is well underway, and the buzz across industries has never been louder.

If you work in finance, tax, or operations, you probably know the phased rollout based on business turnover:

  • Businesses with annual turnover over RM100 million began issuing e-Invoices in August 2024.
  • Those with turnover above RM25 million complied by January 2025.
  • Over RM5 million by July 2025
  • Over RM1 million by January 2026
  • Moreover, all remaining taxpayers by July 2026

But here’s what many still get wrong:

  • What exactly is an e-Invoice? (Hint: it’s not a PDF.)
  • How will daily processes actually change?
  • And what are the real risks of non-compliance?

At Link4, we’ve worked closely with governments and businesses across Australia, New Zealand, Singapore, and Malaysia. We’ve witnessed the common challenges and pitfalls firsthand.

Here are the top misconceptions Malaysian businesses still hold – and why it’s crucial to clear them up now.

1. “We already send e-Invoices. We use PDF.” 

This is a common misunderstanding. 

A PDF invoice is digital, but it’s not an e-Invoice as defined by Malaysia’s system. Under the IRBM’s mandate, invoices must be structured data files submitted via the MyInvois Portal or through the Peppol network.

It’s not just about sending invoices; it’s about real-time validation with IRBM acting as an intermediary. Without automated integration to handle this validation, you aren’t compliant.

2. “We’re not an early Wave business, so we don’t need to worry yet.” 

 Not quite.

Even if your business is in a later compliance wave, your customers in earlier waves will expect e-Invoices. If you don’t provide them, payment delays can occur.

Early preparation protects your cash flow. 

3. “We’ll just upload invoices manually on the IRBM portal.” 

Technically, you can’t. You need to key in invoice details manually in MyInvois portal.

While bulk uploads are possible in Excel format, manual processing of large volumes without automation remain inefficient and prone to errors, slowing down the workflow and wasting valuable time.

Automation is no longer a luxury – it’s essential. 

 4. “We’ll sort it out when the timeline is near for us.” 

Waiting is risky. 

When your wave arrives, service providers will be swamped, testing slots limited, and your finance team rushed.

Now is the calm before the storm. Use this time to map processes, pick your provider, and start testing early. Those who delay usually pay more – in fees, errors, and stress.

5. “It’s just another compliance headache.” 

It’s so much more than that.

e-Invoicing can bring:

  • Faster payments
  • Streamlined tax reporting
  • Real-time tracking and reconciliation
  • Reduced invoice fraud
  • Improved working capital 

For finance teams tired of chasing paperwork, e-Invoicing offers a smarter, more modern way forward.

This mandate is an opportunity to transform your back office – not just a box to tick. 

How You Can Get Ahead 

Whether you’re a CFO, accountant, or IT lead, start with: 

  • Understanding your transaction flows: Who you invoice, how often, and through which systems.
  • Checking if your software supports Peppol: If not, reach out to your provider or a certified access point like Link4.
  • Involving your teams early: Many failures happen due to internal misalignment. 
  • Setting your own timeline: Don’t wait for IRBM deadlines – test, adjust, and learn proactively.

Final Thought 

Change can be overwhelming – the new systems, jargon, and pressure to get it right. 

From our experience across multiple countries, the winners are those who see e-Invoicing not just as compliance but as a chance to transform their business.

And we’re here to help.
