B2B payments guide for Malaysian businesses (2026)

Key takeaways:

• B2B payments in Malaysia span domestic rails (FPX B2B, DuitNow, IBG, RENTAS), cross-border options (SWIFT, regional QR linkages, multi-currency accounts), and a regulatory layer covering LHDN e-invoicing and the expanded SST.

• No single payment method covers every B2B transaction in Malaysia. FPX B2B is capped at RM1,000,000 per transaction¹, RENTAS handles large-value transfers, and cross-border payments usually need either a SWIFT wire or a multi-currency account.

• Airwallex gives Malaysian businesses one platform for FPX collection, multi-currency accounts, and supplier payouts in 200+ countries at competitive FX rates that save you up to 80% on FX fees.

Looking for a B2B payments guide? You’re in the right place.

B2B payments in Malaysia have become significantly more complex in recent years, as businesses balance domestic payment rails like FPX B2B, DuitNow, IBG and RENTAS with cross-border methods such as SWIFT and multi-currency accounts.

At the same time, finance teams are expected to stay compliant with LHDN e-invoicing requirements and SST regulations, all while managing tighter cash flow visibility and rising foreign exchange costs.

This guide breaks down the B2B payments landscape in Malaysia in 2026, the key payment methods available, and the common challenges finance teams face when moving money locally and internationally.

What are B2B payments?

B2B (business-to-business) payments are transfers of money between businesses for goods or services. They run on different rails and carry different compliance rules from the B2C payments your customers make at checkout.

B2B payments vs B2C payments

Here are the key differences between B2B and B2C payments:

The information in this table has been reviewed to be accurate as of 28 May 2026.

How B2B payments typically work in Malaysia

A B2B payment in Malaysia usually runs through four stages:

1. The buyer issues a purchase order (PO)

2. The supplier delivers and sends an invoice

3. Finance matches the invoice against the PO

4. Payment is released through the chosen rail

Under LHDN's MyInvois mandate, the invoice step now includes real-time LHDN validation for businesses in scope. The PO number sits in the Business Reference field on the validated e-invoice, which is what your accounts payable (AP) system uses for matching.

For more details on the workflow, see our guides to invoice processing and accounts payable.

7 B2B payment methods in Malaysia

Malaysian businesses have a wider set of rails to choose from than most realise. Some are built for high-volume corporate transfers, others for speed, others for credit terms or international trade. The right one depends on transaction size, urgency, and who you're paying.

1. FPX B2B

FPX (Financial Process Exchange) B2B is PayNet's online direct-debit service for corporate accounts.

Your finance team initiates a payment through corporate internet banking, the system pulls funds directly from the company current account, and the payment settles in near real time across participating Malaysian banks.

The key feature is the transaction ceiling: FPX B2B supports payments of up to RM1,000,000 per transaction¹ — far higher than the consumer FPX limit. That makes it a fit for large supplier settlements, intercompany transfers, and one-off invoice payments where you want the speed of an online payment without the per-transaction processing fees of card rails.

2. DuitNow Transfer for business

DuitNow Transfer is the instant credit-transfer service that uses simple proxies instead of full account numbers. For businesses, the proxy is your Business Registration Number (BRN), which you register once against a corporate current account.

Once registered, payers send funds to your BRN and money lands in your account within seconds, 24/7 — including weekends and public holidays. Business limits are high: most banks allow up to RM10,000,000 per transaction for corporate accounts on DuitNow².

It's the easiest rail for ad-hoc supplier payments, contractor settlements, and customer refunds when you don't want to handle bank account details.

3. Interbank GIRO (IBG) and RENTAS

IBG and RENTAS sit at opposite ends of the bulk-versus-large-value spectrum.

IBG is PayNet's batch credit-transfer service, built for high-volume payments like payroll, supplier disbursements, and mass refunds. Transfers initiated before 4:00 pm on a business day are credited the same business day; transfers initiated after 4:00 pm are credited the next business day³.

Per-transaction fees are typically among the lowest of any domestic rail in Malaysia — exact rates vary by bank — which is why it remains the default for recurring bulk payouts.

RENTAS (Real Time Electronic Transfer of Funds and Securities) is Bank Negara Malaysia's real-time gross settlement system — Malaysia's only large-value payment system. Each transaction settles individually and irrevocably. There is no limit between RENTAS members, and the minimum for third-party payments is RM10,000⁴.

RENTAS is used for high-value time-critical transfers (large supplier settlements, property purchases, intercompany funding), typically initiated over the counter at your bank.

4. Telegraphic transfers

A telegraphic transfer (TT), also called a wire transfer, is the traditional way to pay an overseas supplier in foreign currency. Your bank instructs a correspondent bank to credit the beneficiary, usually via the SWIFT network.

TTs are reliable and accepted everywhere, but they're the most expensive rail in your stack: you pay your bank's outward fee, a correspondent bank fee, and an FX spread on the conversion. Settlement runs one to five business days depending on the corridor. We cover the cost trade-offs in the cross-border section below.

5. Corporate cards

Corporate cards (commercial credit and debit cards) let your team pay suppliers, software subscriptions, travel, and small-ticket procurement without raising an invoice through accounts payable.

They're well suited to recurring SaaS, marketing spend, and any supplier that accepts card payments. The trade-off is the merchant discount rate that suppliers absorb, which means many B2B vendors discourage card payments for large invoices.

6. Trade credit

Trade credit is the most common B2B payment "method" of all. With this option, your supplier delivers goods or services and invoices you on net 30, net 60, or net 90 terms. Payment then settles through one of the rails above when the invoice falls due.

It's a working-capital tool, not a payment rail, but it shapes which rail you use and when.

7. Letters of credit

For high-value international goods trade, a letter of credit (LC) is a bank-issued undertaking to pay the supplier once they present shipping documents that meet the agreed terms.

LCs reduce counterparty risk on both sides, which is useful when you're dealing with a new overseas supplier or shipping commodities. They're slow and document-heavy, so most Malaysian businesses use them only for large physical-goods imports where the risk profile justifies the overhead.

3 cross-border B2B payment options from Malaysia

Most growing Malaysian businesses pay or get paid by counterparties outside the country. Four corridors are particularly popular: China, Malaysia's largest trading partner; Singapore, the largest ASEAN partner; Indonesia; and Thailand.

Here's how the main cross-border payment options compare:

1. SWIFT wires

SWIFT is the default for international B2B payments. Your bank sends a message through the SWIFT network to a correspondent bank, which forwards it to the beneficiary's bank. The system is universal — almost every business in the world can receive a SWIFT payment in their home currency.

The trade-off is cost. A single outbound SWIFT wire from a Malaysian bank typically carries three layers of fees:

1. An outward telegraphic transfer fee charged by your bank

2. A correspondent bank charge deducted in transit

3. An FX spread on the currency conversion

The FX spread is the largest hidden cost: Malaysian banks routinely apply a markup of two to three percent over the mid-market rate on B2B currency conversions. Settlement runs one to five business days depending on the corridor and the number of correspondents involved.

2. Local rails and regional cross-border QR

ASEAN's central banks have built real-time rail linkages that bypass SWIFT for smaller cross-border transfers. For example:

• PayNet's DuitNow Cross-Border QR connects Malaysian businesses and consumers with merchants in Indonesia, Thailand, and Singapore through the QRIS, PromptPay, and PayNow networks⁵.

• The PayNow-DuitNow link supports real-time person-to-person transfers up to RM3,000 per day between Singapore and Malaysia⁶.

For B2B, these rails are most useful for small recurring payments. For larger supplier payments, they don't yet replace bank-to-bank transfers.

3. Multi-currency business accounts

A multi-currency business account lets you hold, send, and receive multiple currencies under one platform, without being forced to convert into ringgit at every step.

For example, you can collect USD from a US customer into a USD balance, pay a USD invoice from the same balance, and in doing so, avoid two rounds of FX fees.

LHDN e-invoicing and B2B payments: What you need to know

LHDN's MyInvois mandate sits on top of every B2B payment in scope. From 1 January 2026, businesses with annual turnover above RM1 million must issue validated e-invoices for all B2B transactions, regardless of value⁷. That changes both the format of supplier invoices and the timing of your payment cycle.

Three points matter most for payments.

• The purchase order (PO) number now lives in the Business Reference field of the validated e-invoice, which is what your accounts payable system uses for matching.

• Once LHDN validates an e-invoice you have 72 hours to reject it if there's an error. After that, any correction has to go through a credit, debit, or refund note⁸.

• When you pay a foreign supplier who isn't subject to MyInvois, you must issue a self-billed e-invoice on their behalf and submit it for validation⁸.

For operational details, see our guides to invoice processing and purchase orders.

How SST affects B2B payment costs

The 1 July 2025 SST expansion brought financial services into scope for the first time. For most Malaysian businesses, that means an extra layer of cost on the fees you pay to move money.

The 8% service tax on financial services

From 1 July 2025, financial services charged for a fee, commission, or similar payment are subject to 8% service tax, with a registration threshold of RM500,000 in taxable services over 12 months⁹.

In practice, that brings most B2B payment-related bank fees into scope — telegraphic transfer fees, FPX merchant charges, trade finance fees, and FX commissions. Basic banking services (such as standard account maintenance) are excluded, but the fee components on most outbound and cross-border payments now carry the 8% line.

B2B exemption and where it applies

The B2B exemption for financial services is narrower than many businesses assume.

Under the RMCD's Guide on Financial Services, the financial-services B2B exemption applies primarily to persons regulated by the Labuan Financial Services Authority⁹ — it's not a general carve-out for any B2B transaction.

Group relief is available for some other service categories (such as legal, accounting, IT, and consultancy under Group G) where the supplier and recipient sit in the same corporate group, but that relief generally doesn't extend to bank fees on B2B payments.

The practical takeaway: budget for 8% SST on most of your transaction-level bank charges.

3 common B2B payment challenges in Malaysia

Malaysian businesses often face operational and cost-related issues that make B2B payments slower, less transparent, and harder to manage at scale.

Here are the three most common challenges that Malaysian businesses face:

1. Hidden FX markups on cross-border payments

The biggest cost on an international B2B payment is usually the FX markup, not the wire fee.

When you pay a USD invoice through your Malaysian bank, the bank converts ringgit to USD at a rate that sits above the mid-market rate (what you see on Google) — and the markup is rarely shown on the transfer slip.

Layer in the 8% SST on FX commissions and trade finance fees⁹, plus correspondent bank charges, and a single overseas supplier payment can cost meaningfully more than the wire fee suggests.

2. Slow settlement on international wires

A typical SWIFT payment from Malaysia takes one to five business days, depending on the corridor and the number of correspondent banks involved. If the payment is flagged for compliance review, hits a non-working day in the receiving country, or routes through multiple intermediaries, it can take even longer.

This strains supplier relationships and disrupts production schedules when goods are held against payment confirmation.

3. Reconciliation across multiple bank portals

Most Malaysian businesses run more than one bank: a domestic bank for FPX and DuitNow, a foreign bank for USD or CNY, and sometimes a separate trade finance bank for LCs. Each one has its own portal, statement format, and export schedule.

Finance teams end up downloading CSVs, matching them by hand against invoices, and chasing missing references. The MyInvois layer helps with the invoice side (see our guide to invoice processing), but it doesn't solve fragmented payment data.

How to optimise B2B payments

Optimising B2B payments starts with choosing the right mix of payment rails. Here’s how you can optimise your payments:

1. Match the rail to the transaction

Pick the rail based on transaction size, urgency, and currency — not on what your bank's portal defaults to.

• For instant domestic supplier payments under RM10 million, DuitNow Transfer to the supplier's Business Registration Number settles in seconds at low cost².

• For one-off corporate transfers up to RM1 million from internet banking, FPX B2B is the simplest option¹.

• For high-value time-critical transfers, use RENTAS.

• For recurring bulk disbursements (payroll, supplier batches), use IBG.

• For overseas payments, default to a multi-currency account or a non-bank cross-border provider before reaching for a SWIFT wire.

2. Use a multi-currency account with like-for-like settlement

If you pay or get paid in more than one currency, switching to a multi-currency business account will make the biggest impact.

With a multi-currency account, you can collect USD into a USD balance, pay USD invoices from the same balance, and only convert to ringgit when you actually need ringgit. This is called like-for-like settlement.

This removes the forced round-trip FX that most Malaysian banks apply on every cross-border flow, and eliminates two rounds of FX fees that you’d otherwise have to pay.

Why Malaysian businesses choose Airwallex for B2B payments

A single domestic bank works fine if every supplier you pay is local and every customer who pays you settles in ringgit. For small, all-domestic operations, FPX B2B and DuitNow through your existing corporate bank account will do the job.

But most growing Malaysian businesses don't fit that profile. You're paying suppliers in China. You're collecting from international customers in USD or EUR. You're juggling two or three bank portals, exporting CSVs to reconcile them, and watching FX markups eat into your margins on every cross-border payment.

That's where Airwallex comes in. Here’s what you get with Airwallex:

Global Accounts in 20+ currencies

With an Airwallex Global Account, you can open local-currency accounts in 20+ currencies, with no monthly fees or minimums. Collect from international customers in their own currency, hold the balance, and pay out from the same currency without forced conversion into ringgit. This helps you avoid unnecessary FX fees.

Interbank FX rates with savings of up to 80% on FX fees

When you do need to convert, Airwallex applies FX rates of 0.4% to 0.6% above interbank, saving you up to 80% on FX fees compared with traditional banks. There are no per-transfer fees on most major corridors, so the cost you see is the cost you pay.

One platform for collection, payout, and spend

Collect via FPX, pay overseas suppliers in 200+ countries, and issue multi-currency corporate cards to your team — all from the same dashboard, with one reconciliation feed into your accounting system. Fewer bank portals, fewer CSVs, less manual work.

Frequently asked questions (FAQs)

What are B2B payments?

B2B (business-to-business) payments are transfers of money between two businesses for goods or services — for example, a Malaysian retailer paying an overseas supplier. They differ from B2C payments in transaction size, settlement timing, approval workflow, and the regulatory layer that applies.

What is the FPX B2B transaction limit?

FPX B2B supports payments of up to RM1,000,000 per transaction¹ for corporate accounts. Your actual ceiling can be lower depending on the internet banking limit your bank has set for your account.

What's the fastest way to pay an overseas supplier from Malaysia?

It depends on the corridor. For Singapore, Indonesia, or Thailand, regional QR linkages can settle smaller payments in seconds. For larger transfers, a multi-currency account with local payment rails in the destination country is faster than a SWIFT wire — Airwallex routes 94% of its transfers through local rails instead of SWIFT.

Is e-invoicing mandatory for B2B transactions in Malaysia?

Yes, for businesses in scope. From 1 January 2026, businesses with annual turnover above RM1 million must issue validated e-invoices for all B2B transactions, regardless of value⁷. Smaller businesses are being phased in over later rollout stages.

Does SST apply to B2B payment fees?

Yes, in most cases. From 1 July 2025, financial services charged for a fee or commission are subject to 8% service tax⁹, including telegraphic transfer fees, FX commissions, and trade finance charges. The B2B exemption is narrow and doesn't generally cover bank fees.

What's the cheapest way to make cross-border B2B payments?

The cheapest option is usually a multi-currency business account paired with FX close to the interbank rate, rather than a SWIFT wire through your domestic bank. Airwallex lets Malaysian businesses hold 20+ currencies and convert at interbank rates.
