Vendor payment automation in Malaysia: 2026 guide

Key takeaways:

• LHDN's MyInvois mandate means businesses can no longer rely on manual invoice processing. As invoice volumes grow, automating accounts payable helps finance teams stay compliant while reducing manual work.

• Overseas supplier payments often come with telegraphic transfer (TT) fees, FX markups, and 8% SST on bank charges. Paying through local payment rails can help reduce these costs.

• Airwallex Bill Pay brings invoice capture, approval workflows, multi-currency payments, and accounting reconciliation together in one platform, with integrations for Xero, QuickBooks, and NetSuite.

Vendor payment automation is becoming more important as Malaysian businesses work with more suppliers, both locally and overseas.

For many finance teams, approving invoices is only part of the process. The payment itself can also be expensive and time-consuming, especially when overseas transfers involve TT fees, FX markups, and manual reconciliation.

This guide explains how vendor payment automation works, what to look for in a solution, and how Airwallex Bill Pay helps Malaysian businesses manage invoice approvals, supplier payments, and reconciliation from one platform.

What vendor payment automation changes for Malaysian businesses

The individual steps of paying a supplier aren't complicated.

The issue is that each one is manual, disconnected, and repeated dozens of times a month, and in 2026, there's a new layer on top: validating MyInvois e-invoices, storing UINs, and generating self-billed invoices for overseas vendors who can't issue LHDN-compliant documents.

Vendor payment automation connects these disconnected steps into a single workflow, from invoice capture through to payment and reconciliation.

Instead of switching between inboxes, spreadsheets, bank portals, and accounting software, your team manages the entire accounts payable process from one place.

Here's a quick overview of how your workflow changes with automation:

The rest of this guide walks through each stage in detail, showing how Airwallex Bill Pay handles invoice capture, approval routing, payment execution, and reconciliation, alongside the compliance steps specific to Malaysia.

Why Malaysian AP teams are automating in 2026

Accounts payable has become more complex for Malaysian businesses over the past two years. The rollout of MyInvois has changed how invoices are processed, while more businesses are paying suppliers overseas and dealing with higher international payment costs.

Here's where the MyInvois rollout stands today:¹

For businesses in Phase 4, the mandate is already in effect.

While the relaxation period gives businesses more time to adjust, e-invoicing is now part of day-to-day accounts payable rather than something finance teams can plan for later.

At the same time, many Malaysian businesses are buying more goods and services from overseas suppliers. Every international payment can come with telegraphic transfer (TT) fees, FX markups, and 8% SST on bank charges.

Some of these costs appear as separate fees, while others are built into the exchange rate, making them easy to overlook.

Step 1: Invoice capture: OCR, MyInvois e-invoices, and self-billed e-invoices

Getting invoice data into your system accurately is the first step in any AP workflow. For Malaysian businesses, this now involves three different types of invoices, each requiring different handling.

Here's a quick overview:

Standard PDF invoices

Many local suppliers, particularly those below the RM1 million turnover threshold, still send invoices as PDF attachments by email.

In Airwallex Bill Pay, you can drag and drop these into the platform or forward supplier emails to a dedicated Bill Pay inbox. From there, optical character recognition (OCR) and AI extraction read the document and pull out the key fields.

Before any invoice reaches the approval queue, Bill Pay also checks it against existing records. If the invoice number, amount, and due date match a bill already in the system, it gets flagged as a potential duplicate.

MyInvois e-invoices

For suppliers who are already on MyInvois, validated e-invoices arrive in XML or JSON format carrying an LHDN-assigned Unique Identifier Number (UIN) and QR code.²

Your AP platform needs to handle this format directly, storing the UIN alongside the invoice record and flagging the 72-hour window during which you can reject the invoice if something is wrong.

After 72 hours, the invoice locks and any correction requires a credit note, debit note, or refund note referencing the original UIN.

Self-billed e-invoices for overseas suppliers

When you buy goods or services from an overseas supplier, that supplier cannot issue an LHDN-validated e-invoice. Under Malaysia's e-invoicing rules, the buyer is responsible for generating a self-billed e-invoice, submitting it to LHDN for validation, and storing the UIN.³

Most businesses handle self-billed e-invoice generation through their accounting software or a MyInvois-compatible solution, then store the validated UIN alongside the payment record for audit purposes.

Airwallex Bill Pay routes these overseas vendor bills through your approval workflow once the invoice has been processed; your team then reviews and confirms the payment directly in Bill Pay, which executes the transfer through local payout rails.

Step 2: Automated approval routing by amount and vendor

Once an invoice clears the capture stage, it moves into the approval workflow. You set the rules once and the system routes every invoice accordingly.

Here's a quick overview of how a typical Malaysian finance team might set this up:

These thresholds are illustrative: you can configure them to match your own authorisation policy. You can also add rules by vendor category, currency, or cost centre.

For example, a recurring utility bill below threshold may cleas automatically, while a first-time overseas vendor at any amount can be routed for review.

Approvers get a notification when an invoice lands in their queue. They can see the extracted invoice data, supplier details, and payment amount before approving or sending it back.

There’s no need to log into a desktop system to action it. Every approval or rejection is timestamped and stored, creating an audit record that replaces the email chain entirely.

Step 3: Batch payments via local rails: domestic and cross-border

Once invoices are approved, they move into the payment queue. Rather than executing each transfer individually through a bank portal, Airwallex Bill Pay lets you group all approved invoices into a single batch run, regardless of currency or destination.

Here's a quick overview of how payments are routed by destination:

For local Malaysian suppliers, payments go out through FPX B2B, DuitNow, or Interbank GIRO (IBG): the same domestic rails your bank uses, without the manual step of logging into a portal for each one.

Why local rails matter for overseas supplier payments

When a payment travels via SWIFT, it passes through a chain of correspondent banks before reaching the recipient. Each bank in that chain can add fees and processing time, and those deductions sometimes mean your supplier receives less than you sent.

In contrast, local rails bypass that chain entirely, settling payments directly through the banking system in the destination country.

Airwallex routes 94% of transactions through local payment rails.⁴ For Malaysian businesses paying overseas suppliers, this means:

• No SWIFT fees on 94% of transfers

• 93% of transfers arrive on the same working day

• 45% arrive immediately

That's a significant difference from the one-to-three working day window typical of a Maybank Foreign Telegraphic Transfer (FTT) via SWIFT.⁵

Step 4: The real cost of paying overseas vendors from Malaysia

Most Malaysian businesses expect to pay a fee when sending money overseas.

What many don't realise is that a telegraphic transfer (TT) can involve several different charges, and the biggest cost is often the one that's hardest to spot: the exchange rate.

Here's what you typically pay when sending an international transfer through a traditional Malaysian bank:

For example, Maybank charges a flat RM10 fee for online foreign telegraphic transfers, with 8% SST applied to the service fee and any agent bank fees.⁵ Agent or correspondent bank fees depend on the payment route and may be deducted before the money reaches your supplier.

For many businesses, the FX markup is the largest cost of an international transfer. Unlike a TT fee, the FX markup isn't listed separately.

Instead, it's built into the exchange rate quoted by the bank, making it difficult to see the true cost of the transfer. Traditional Malaysian banks typically apply a 2–3% markup above the interbank rate on international payments.⁶

The table below compares the typical cost of paying a RM45,000 overseas supplier invoice (approximately US$10,000 at RM4.50/US$1) through a traditional Malaysian bank versus Airwallex Bill Pay:

Illustrative example only. MYR/USD rate assumed at RM4.50. Bank FX markup estimated at 2.5%, representing the midpoint of the typical 2–3% range. Airwallex rate of 0.4–0.6% above interbank applies to major currencies including USD. Actual costs will vary by currency pair, transfer amount, and prevailing exchange rate. Verify current rates directly with your provider before transacting.

In this illustrative example, using Airwallex helps you reduce payment costs by ~RM1,000 on a single overseas transfer. For businesses making regular international supplier payments, those savings can add up over time.

Step 5: Compliance: MyInvois, SST, withholding tax, and LHDN record-keeping

Automated AP produces the documentation LHDN expects for audits, SST filing, and tax deductions. Here's what that covers:

MyInvois audit trail

Every validated e-invoice carries a UIN and QR code that LHDN uses as the primary audit reference. Your AP system should store the structured data alongside the payment record and approval log. LHDN requires businesses to retain tax records for seven years.⁷

SST on supplier invoices

When a Malaysian supplier charges service tax, your AP tool should apply the correct rate and map it to the right tax code for SST return filing.

The rate depends on the service category: 6% applies to food and beverage, telecoms, logistics, and parking; 8% applies to most other taxable services, including leasing, construction, and financial services following the July 2025 scope expansion.⁸

Withholding tax on overseas vendor payments

When you pay a non-resident supplier for services, royalties, or technical fees, you may be required to withhold tax before releasing the payment and remit it to LHDN within one month.⁹ Here's a quick overview of the most common scenarios:

There are two practical points worth knowing:

1. If the withholding tax on a single transaction is RM500 or less, you can defer and batch-remit half-yearly using forms CP37S or CP37DS instead of filing monthly.⁹ This is relevant for businesses paying multiple small SaaS subscriptions.

2. Malaysia has over 70 Double Taxation Agreements (DTAs) that can reduce WHT rates, but your supplier needs to provide a Certificate of Residence (COR) from their home tax authority for the reduced rate to apply.

Note that 8% SST on imported digital services is a separate obligation paid to the Royal Malaysian Customs Department (RMCD), not LHDN. The same overseas vendor payment can trigger both; they are different taxes filed with different agencies.

Automated AP doesn't remove these obligations, but it creates the payment records you need to track applicable transactions, file accurately, and support any DTA claims.

If you're unsure whether your overseas vendor payments are subject to withholding tax, consult a licensed Malaysian tax adviser.

Step 6: Reconciliation

Once a payment clears, Airwallex Bill Pay pushes the transaction data to your accounting system automatically. There's no CSV export, no manual matching, and no end-of-month scramble to reconcile bank statements against invoices.

Here's a quick overview of how native two-way sync compares to a CSV-based approach:

Airwallex Bill Pay integrates natively with Xero, QuickBooks, and NetSuite.

For businesses on Xero, QuickBooks, or NetSuite, transaction-level data (including the MYR equivalent, FX rate applied, and tax code) pushes to your accounting system automatically after each payment clears, mapping to what you need for SST return filing without manual reconstruction from bank statements.

Grants and incentives: MSME MyInvois tax deduction

If your business is implementing e-invoicing, there is a tax incentive worth claiming.

MSMEs can claim a special tax deduction of up to RM50,000 per year of assessment on qualifying e-invoicing implementation costs, including consultation fees, software subscriptions, and integration development.¹⁰ This is available from Year of Assessment 2024 through to Year of Assessment 2027.

To be eligible, your business generally needs to meet MSME criteria: meaning it should not be a subsidiary, have non-individual shareholders with turnover above RM1 million, or be part of a related company or joint venture above that threshold.

If you are unsure whether your business qualifies, check with a licensed tax agent or refer to hasil.gov.my.

Qualifying expenditure includes costs directly related to getting your AP and invoicing systems onto MyInvois — which means the implementation work you do to automate invoice capture, integrate with accounting software, and connect to the MyInvois system can all contribute toward the deduction.

In addition, MDEC and SME Corp periodically run separate digitalisation grant programmes for broader technology adoption. These vary by application window, so check smecorp.gov.my and mdec.com.my for any currently open schemes.

What to check before switching your AP workflow

Before committing to an AP automation platform, run through this checklist.

ERP and accounting integration:

• Does the platform offer native two-way sync with your accounting system, or is it CSV export only?

• Is the sync real-time or batched?

MyInvois compatibility:

• Can it ingest LHDN-validated e-invoices in XML/JSON format, store the UIN, and track the 72-hour acceptance window?

• How does it handle self-billed e-invoices for overseas vendors?

Payment rail coverage

• Does it support local rails for your main outbound corridors?

• Does it support FPX B2B, DuitNow, and IBG for domestic MYR payments?

• What is the fallback for corridors not on local rails?

Approval workflow configurability

• Can you set rules by MYR amount threshold, vendor category, and cost centre?

Compliance and licensing

• Is the platform licensed by Bank Negara Malaysia? You can verify Airwallex's status on the BNM financial institutions directory.

• Does it produce transaction-level records for LHDN audits, SST filing, and 7-year retention?

FX transparency

• Is the FX margin published and fixed, or variable and bundled into the quoted rate?

• Can you hold MYR and foreign currency balances and pay out without forced conversion?

Frequently asked questions (FAQs)

How do I automate vendor payments in Malaysia?

Vendor payment automation in Malaysia typically involves four stages: invoice capture via OCR or MyInvois e-invoice ingestion, approval routing by amount threshold and vendor category, batch payment execution via local rails, and reconciliation into your accounting system. Platforms like Airwallex Bill Pay handle all four stages in one workflow, without requiring you to change your existing accounting software.

What are the TT fees for paying overseas suppliers from Malaysia, and how do I avoid them?

When you send a telegraphic transfer (TT) through a Malaysian bank, you typically pay a service fee, 8% SST on that fee and any agent bank fee, plus a correspondent bank fee deducted along the SWIFT route.⁵ On top of that, the bank applies an FX markup built into the exchange rate, which doesn't appear as a separate line item. Routing payments through local rails instead of SWIFT eliminates most of these costs. Airwallex routes 94% of transfers through local rails, with no SWIFT fees on those transactions.⁴

Does vendor payment automation help with LHDN MyInvois compliance?

Automated AP helps you manage the documentation MyInvois compliance requires. For validated e-invoices from local suppliers, your AP system needs to store the UIN and track the 72-hour acceptance window.² For overseas suppliers who can't issue LHDN-validated e-invoices, you'll need to generate self-billed e-invoices separately and store the validated UIN alongside each payment record.³ Automated AP creates the structured, transaction-level audit trail LHDN expects, with seven-year retention built in.⁷

Do I need to withhold tax when paying overseas suppliers from Malaysia?

It depends on the type of payment. Royalties (including SaaS subscriptions), technical fees, and contract payments to non-resident suppliers are generally subject to withholding tax under the Income Tax Act 1967, at rates of 10% or 13% depending on the section that applies.⁹ You must remit the withheld amount to LHDN within one month of payment. If the WHT on a single transaction is RM500 or less, you can defer and batch-remit half-yearly instead.

Is Airwallex licensed in Malaysia for business payments?

Yes. Airwallex (Malaysia) Sdn. Bhd. is licensed to provide remittance services in Malaysia under the Money Services Business Act 2011.⁶ Customer funds are safeguarded in segregated accounts with licensed banks and kept separate from Airwallex's own operating funds.
