Direct MyInvois Submission
Submit e-Invoices from Synergy through API integration instead of entering the same transaction manually into a separate portal.
LHDN e-Invoice Software Malaysia, Integrated with Your Accounting & POS
Create, validate, submit and track e-Invoices directly from Synergy Accounting and POS. Reduce duplicate data entry, identify submission errors earlier and keep your sales records connected to the MyInvois workflow.
Latest MyInvois preparation: HASiL announced TIN and
BRN validation for the Validate Taxpayer's TIN API from 1 August 2026,
followed by additional production field validations from 15 August
2026. Businesses should keep buyer master data accurate and use
software that can identify incomplete or invalid fields before
submission.
What Is an e-Invoice in Malaysia?
An e-Invoice is a structured digital representation of a transaction between a supplier and a buyer. It records information such as supplier and buyer details, item descriptions, quantity, price, tax and total amount. Unlike an ordinary PDF or printed invoice, an e-Invoice is submitted to LHDN's MyInvois system for validation.
Malaysia's e-Invoice framework covers business-to-business (B2B), business-to-consumer (B2C) and business-to-government (B2G) transactions. It also includes invoice, credit note, debit note, refund note and specified self-billed e-Invoice scenarios.

The transaction begins in the system your team already uses. Synergy prepares the required information, submits it to MyInvois and records the returned validation result.
Malaysia e-Invoice Implementation Timeline
| Annual Turnover or Revenue | Mandatory Implementation Date |
|---|---|
| More than RM100 million | 1 August 2024 |
| More than RM25 million and up to RM100 million | 1 January 2025 |
| More than RM5 million and up to RM25 million | 1 July 2025 |
| Up to RM5 million | 1 January 2026 |
| Qualifying taxpayers below RM1 million | Exempt, subject to LHDN's exemption criteria |
Important: The RM1 million exemption is not determined by turnover alone. Certain taxpayers below RM1 million, including some subsidiaries or related-company situations, may not meet the exemption criteria and may have a separate implementation date. Confirm your position using the latest LHDN guideline or professional tax advice.
Interim relaxation: The current LHDN FAQ states that taxpayers with turnover or revenue up to RM5 million whose implementation date falls on 1 January 2026 or 1 July 2026 have an interim relaxation period until 31 December 2027. This does not mean e-Invoice implementation can simply be ignored; the applicable relaxation treatment and conditions should still be followed.

Frequently Asked Questions
1. Is a PDF invoice the same as an LHDN e-Invoice?
No. A PDF may be the visual representation shared with the buyer, but the e-Invoice itself is structured transaction data submitted to and validated by MyInvois.
2. Can I edit an e-Invoice after it has been validated?
No. Within 72 hours, the buyer may request rejection and the supplier may cancel. After the permitted window, corrections generally require an appropriate credit note, debit note or refund note e-Invoice.
3. Does a buyer's rejection request automatically cancel the e-Invoice?
No. The supplier receives the request and, if agreeable, must cancel the e-Invoice within 72 hours from the original validation time.
4. Does every business below RM1 million automatically qualify for exemption?
No. The exemption is subject to LHDN's criteria. Certain ownership, subsidiary or related-company circumstances can affect eligibility.
5. What is a consolidated e-Invoice?
For eligible transactions where buyers do not request individual e-Invoices, the supplier may aggregate the relevant receipts and submit a consolidated e-Invoice within seven calendar days after month-end, subject to LHDN rules and industry exceptions.
6. What is a self-billed e-Invoice?
It is an e-Invoice issued by the buyer in specific circumstances prescribed by LHDN, such as certain transactions involving foreign suppliers or payments to agents, dealers or distributors.
7. Why use API-integrated software instead of entering invoices manually?
API integration can reuse accounting and POS data, return validation status to the original transaction and reduce repetitive data entry. It is particularly useful where transaction volume is higher.
8. What should I prepare before implementation?
Review customer TIN and BRN information, tax codes, item descriptions, MSIC details, user responsibilities, invoice adjustments, consolidated transaction rules and the connection between sales and accounting records.
