LHDN e-Invoice Phase 4 is LIVE — All Malaysian businesses must comply. Check your compliance →
LHDN Phase 4 · LIVE since Jan 2026

Submit every invoice to LHDN MyInvois without leaving AutoCount.

AutoCount e-Invoice On-Prem is the official add-on that connects AutoCount Accounting 2.0 directly to the LHDN MyInvois portal. On invoice posting, AutoCount submits to MyInvois, captures the Unique Identification Number (UIN), and shows real-time status on every invoice record. Phase 4 went live January 2026 — every Malaysian business is in scope. Daxonet is an authorised AutoCount dealer with 10+ years on the platform. We handle TIN registration, sandbox testing, edge cases like self-billed and consolidated invoices, and pick up the WhatsApp when LHDN rejects a submission.

In short

AutoCount e-Invoice On-Prem is the official LHDN MyInvois add-on for AutoCount Accounting 2.0 that submits every invoice posted in AutoCount directly to the Malaysian MyInvois portal, captures the Unique Identification Number (UIN), validates the response, and surfaces real-time status on every invoice record. It handles standard invoices, credit notes, debit notes, self-billed invoices and consolidated invoices for B2C retail transactions, plus edge cases such as foreign-customer invoicing and intercompany invoicing that often break workaround bridges. Phase 4 of the LHDN e-Invoice mandate went live in January 2026, which means every Malaysian business is in scope and manual MyInvois submission is no longer practical at scale. Daxonet is an authorised AutoCount dealer with 10+ years on the platform and supports clients across Klang Valley, Penang, Johor and the rest of Malaysia in English, Bahasa Melayu and Mandarin. Implementation includes TIN registration assistance, AutoCount e-Invoice add-on installation and licence, LHDN sandbox testing across at least 10 invoice types, production cutover with live monitoring, and the first month of WhatsApp post-go-live support.

What Daxonet sets up

Six deliverables · one engagement.

From TIN registration to the first month of WhatsApp support, Daxonet covers every step. Your finance team signs off the sandbox results before we flip production.

01

TIN registration assistance

We register or verify your business TIN with LHDN, set up MyInvois portal access for your finance team, and confirm role permissions.

02

Add-on installation + licence

AutoCount e-Invoice On-Prem add-on installed on your AutoCount Accounting 2.0 environment. Licence keys configured. Connectivity to LHDN tested.

03

Sandbox test cycle

10+ invoice types submitted to the LHDN sandbox: standard, credit, debit, self-billed, consolidated, foreign customer, intercompany, B2C consolidated, voided, amended.

04

Production cutover

Live monitoring on the first day of production submission. Daxonet sits with your finance team. Any rejection is resolved before it sits in limbo.

05

Edge cases handled

Foreign customer invoicing, intercompany invoicing within group entities, POS daily consolidation, voided and amended invoices — all configured and tested.

06

WhatsApp post-go-live

First month of WhatsApp support included. Daily exception report flags any rejected submission. Statutory updates handled by Daxonet so you do not track LHDN changes yourself.

Five invoice flows · all configured

Which LHDN e-Invoice flow types are covered?

All five core flows plus edge cases. The bridge engines that workaround tools rely on usually break here. The native AutoCount add-on does not.

Flow 01

Standard

B2B sales invoice. Customer TIN + line items + SST.

Flow 02

Credit Note

Refund or return reference. Linked back to original invoice UIN.

Flow 03

Debit Note

Additional charge after original invoice. Linked back to UIN.

Flow 04

Self-Billed

Buyer issues invoice on behalf of seller (foreign supplier, exempted).

Flow 05

Consolidated

Daily B2C retail rollup. POS sales batched into one consolidated invoice.

Penalty exposure · Income Tax Act

What does LHDN charge for a missed e-Invoice?

Under the Income Tax Act, LHDN can impose a fine, imprisonment, or both. The penalty is per offence — missed or rejected invoices accumulate. Phase 4 is live, no further grace period for any business size.

RM 200 to RM 20,000

Fine, per offence

Up to 6 months

Imprisonment

Both

Fine + imprisonment may apply

Source · Income Tax Act 1967, section 120(1). Daxonet's setup includes audit trail and submission monitoring for any LHDN audit query.

Integration flow

How does an invoice travel from AutoCount to LHDN?

Frequently asked

Common questions Malaysian SMEs ask before going live on MyInvois.

What is AutoCount e-Invoice On-Prem and who needs it?
AutoCount e-Invoice On-Prem is the official LHDN MyInvois add-on for AutoCount Accounting 2.0. It is required for any Malaysian business that issues invoices and runs AutoCount Accounting 2.0 on-premise. As of January 2026 (Phase 4 of the LHDN mandate), every Malaysian business is in scope regardless of revenue. Manual entry on the MyInvois portal does not scale beyond a handful of invoices per month, and one typo gets a submission rejected. Daxonet implements the add-on for retail, F&B, trading, services and light manufacturing SMEs across Malaysia.
Is AutoCount e-Invoice On-Prem the same as the standalone Daxonet e-Invoice middleware?
No. AutoCount e-Invoice On-Prem is the native add-on inside AutoCount Accounting 2.0. It runs on the same database as your accounting and posts directly. Daxonet e-Invoice middleware is a separate bridge for businesses that do not run AutoCount, for example those still on legacy accounting software, manual Excel, custom in-house systems or D365. If you are on AutoCount, the on-prem add-on is the right pick. If you are not on AutoCount, the standalone middleware is the right pick. Daxonet implements both.
Which e-Invoice flows does the AutoCount add-on cover?
All five core flows: standard invoices, credit notes, debit notes, self-billed invoices, and consolidated invoices for B2C retail transactions. Edge cases are also covered: foreign-customer invoicing, intercompany invoicing within group entities, and POS daily consolidation when paired with AutoCount POS 5.0. Daxonet configures all flows during go-live and tests at least ten invoice types against the LHDN sandbox before cutover.
What does Daxonet set up for me?
Daxonet handles the full setup: TIN registration assistance with LHDN, AutoCount e-Invoice add-on installation and licence, sandbox test cycle across ten or more invoice types, production cutover with live monitoring on the first day of submission, edge cases such as foreign customers, self-billed and consolidated invoices, and the first month of WhatsApp post-go-live support. Your finance team signs off on the sandbox test results before we flip to production.
What are the LHDN penalties for non-compliance?
Under the Income Tax Act, LHDN can impose a fine of RM 200 to RM 20,000 per offence, imprisonment of up to 6 months, or both. The penalty is applied per offence which means missing or rejected invoices accumulate exposure. Phase 4 went live January 2026 and there is no further grace period for any business size. Daxonet's setup includes the audit trail and submission monitoring needed to defend any LHDN audit query, but the cleanest defence is having every invoice flow through the add-on automatically.
How long does the AutoCount e-Invoice add-on take to go live?
For a single-entity Malaysian SME on AutoCount Accounting 2.0, the add-on goes live in 1 to 2 weeks. TIN registration and access takes 3 to 5 days. Add-on installation and configuration takes 2 to 3 days. Sandbox testing across the ten invoice types takes 3 to 5 days. Production cutover and the first day of monitoring takes 1 day. The first month of WhatsApp support is included. Daxonet runs the entire flow with your accountant or finance staff in the room.
What happens if LHDN rejects a submission?
AutoCount surfaces the rejection on the invoice record with the LHDN error code. Common rejection reasons are TIN mismatch, missing line item details, or invalid customer data. Daxonet's setup includes a daily exception report that flags rejected submissions, so they do not sit in limbo. The first month after go-live is monitored by our team — if a rejection volume spikes during that window, we resolve it before your finance team sees it.
Do we still need the e-Invoice add-on if we use AutoCount POS 5.0 for retail?
Yes — and the AutoCount e-Invoice add-on handles the retail B2C flow specially. Daily POS transactions consolidate into a single LHDN consolidated invoice automatically, which is the LHDN-recommended pattern for high-volume B2C retail. Without the add-on you would have to manually consolidate POS sales and submit to MyInvois every day. With the add-on it happens automatically at end-of-day cash-up.
