As part of Malaysia’s broader digitalisation initiative, the Inland Revenue Board of Malaysia (IRBM) has introduced mandatory e-invoicing for registered businesses. This move is aimed at modernising business processes, improving tax compliance, and boosting operational efficiency across the country.

E-invoicing applies to transactions across the board including Business-to-Business (B2B), Business-to-Government (B2G), and Business-to-Consumer (B2C). As more businesses transition to this system, it’s important to understand how e-invoicing works, when it applies, and how your business can prepare.
 


What Is E-Invoicing?

An e-invoice is a fully digital invoice that officially records a sale or transaction between a seller (supplier) and a buyer. It replaces traditional documents like printed invoices, credit notes, and debit notes, meaning businesses don’t need to print or email PDFs anymore.

What makes e-invoices different from just a digital file (like a PDF) is that they are:

So instead of just issuing an invoice and sending it to a customer, the system now requires you to first send it to IRBM, get it validated, and then pass it to your buyer with proof (like a QR code or unique ID) that it’s officially approved.

E-Invoicing Rollout Timeline in Malaysia

E-invoicing in Malaysia is being implemented step-by-step, depending on how much a business earns in a year (its annual turnover or revenue). Instead of forcing all businesses to start at once, the government is giving different deadlines based on company size so large companies start first, and smaller businesses get more time to prepare.

This phased rollout gives businesses time to adapt and make sure they’re ready with the right tools, systems, and processes.
