E-Invoice Software in Malaysia
Simplify E-Invoicing in Malaysia with Bytize
Bytize connects your ERP or POS to LHDN’s MyInvois system by API, so every invoice is validated, given its unique identifier and QR code, and shared with your buyer on time.
LHDN now exempts businesses with annual revenue below RM3 million (General Guideline v4.8, 30 August 2026). Above that threshold, e-invoicing through MyInvois is mandatory.
What is E-Invoicing in Malaysia?
E-Invoicing in Malaysia requires businesses to submit each e-invoice to the Inland Revenue Board of Malaysia (LHDN, also called IRBM) through its MyInvois system. LHDN validates the invoice in near real time and returns a unique identifier, after which you share the validated e-invoice, with its QR code, with your buyer.
A PDF or paper invoice isn't an e-invoice on its own. You can share a readable copy, but it must carry the QR code from the validated e-invoice.
What an e-invoice in Malaysia must follow
- Format: XML or JSON following LHDN's e-invoice specification, based on UBL 2.1
- Submission: Through the MyInvois Portal or by API from your ERP or POS
- Validation: LHDN validates the invoice and assigns a Unique Identification Number (UIN)
- Buyer window: Buyers can reject, and suppliers can cancel, a validated e-invoice within 72 hours
- Content: Supplier and buyer tax identification numbers (TIN), item details, tax and totals across 55 data fields
Who must comply
- Taxpayers with annual revenue of RM3 million or more, phased in by revenue since 1 August 2024
- Covers B2B, B2C and B2G transactions, plus credit, debit and refund notes
- B2C sales can be grouped into a monthly consolidated e-invoice, submitted within 7 days of month-end, unless the buyer asks for an individual e-invoice
- Self-billed e-invoices are needed in specific cases, such as purchases from foreign suppliers

Benefits of E-Invoicing in Malaysia
E-invoicing is a legal requirement, but done well it also speeds up payments and removes manual work from your finance team. Here's what changes when you switch with Bytize.
Stay compliant without extra work
Every invoice is validated by LHDN before it reaches your buyer, so you meet MyInvois rules by default.
Get paid faster
Buyers receive invoices already validated by LHDN, so there’s less back-and-forth and approval starts sooner.
Fewer errors and rejections
Each invoice is validated against the official rules before it's sent, so missing fields and wrong tax codes are fixed before your buyer sees them.
No more manual data entry
Invoices go from your ERP or POS straight to MyInvois, so your team stops re-keying invoices into the portal.
Audit-ready records
Every validated e-invoice and its LHDN response is stored, ready to retrieve when LHDN asks.
