Introduction: The Move to Digital Compliance
E-Invoicing will become required for all Malaysian businesses by 1 January 2026, with a grace period until 30 June 2026 to help SMEs adapt.
Manual Invoicing: Well-Known, But Old-Fashioned
For years, manual invoicing has been the main way most SMEs handle their billing. It’s pretty simple — you make an invoice in Word or Excel, save it as a PDF, and email it (or sometimes even print it out). This straightforward approach to invoicing seems easy, but it has a few problems that aren’t obvious at first:| Common Issues | Description |
| Error-Prone | Manual data entry often leads to typos, wrong totals, or double billing. |
| No Real-Time Validation | Mistakes go unnoticed until audit or payment time. |
| Slow Approval Cycles | Invoices get delayed, lost in email, or overlooked by clients. |
| Difficult Record-Keeping | Paper and PDF archives pile up, making audits stressful. |
| Compliance Risks | Manual invoices are harder to reconcile with LHDN tax data. |
E-Invoicing: The Future of Business Transactions in Malaysia
E-Invoicing is a structured digital invoicing process that enables your system to send invoice data straight to LHDN’s MyInvois platform for checking — in real time. After checking, the invoice gets a unique identification number (IRN) and QR code from LHDN showing it’s real and ready to give to your buyer.E-Invoicing Workflow
1. Invoice Creation:
Made from your accounting or ERP system in XML/JSON format.2. LHDN Checks:
You send your invoice through API or upload it on MyInvois Portal. LHDN reviews info like supplier TIN, amount, and format.3. Go-Ahead & QR Code:
After approval, LHDN gives a validation code and QR to both sides.4. Invoice Sending:
You send the checked invoice to your customer (email or system-to-system).5. Archiving:
Both parties need to keep the e-invoice for at least 7 years.Manual vs E-Invoicing Comparison
