Key Takeaways:
An ACH transfer is a US-based electronic payment system used for payroll, recurring bills, and direct deposits. ACH transfers are processed in batches, not in real time.
As a Malaysian business, you're most likely to encounter ACH when receiving money from US clients or platforms, or when paying US-based suppliers and contractors.
Airwallex gives Malaysian businesses a USD Global Account with local US bank details, so you can receive ACH-originated payments without needing a US bank account.
If you've come across "ACH transfer" in a payout notice from a US platform or a client email, you're not alone.
ACH — short for Automated Clearing House — is the electronic payment network that moves money between banks in the United States1. It handles everything from payroll deposits to utility bill payments and is one of the most widely used payment systems in the world.
This guide explains what ACH is, how it works, what it costs, and what your options are as a Malaysian business when you need to send or receive ACH payments.
What is an ACH transfer?
An ACH transfer is an electronic bank payment that moves money through the Automated Clearing House network, a system that connects thousands of financial institutions across the United States.
The ACH network is governed by Nacha (National Automated Clearinghouse Association), a non-profit organisation that sets the rules for how payments are processed. Nacha has operated the network since the 1970s, when it was created to reduce reliance on paper checks.
Unlike wire transfers, which process one transaction at a time, ACH payments are grouped into batches. Banks collect payments throughout the day and send them in bulk at set intervals. This makes the system efficient and cost-effective — though it means payments are not instant.
There are two types of ACH transfers:
1. ACH credit transfers
An ACH credit transfer pushes money from one account into another. The sender initiates the transfer. Common examples include payroll deposits, government benefit payments, and tax refunds.
When a US employer pays salary directly into an employee's bank account, that's an ACH credit.
2. ACH debit transfers
An ACH debit transfer pulls money out of an account. The recipient — usually a business — initiates the transfer with the payer's prior authorisation. Common examples include recurring utility bills, subscription fees, and mortgage repayments.
When you set up autopay for a monthly bill, you're typically authorising an ACH debit.
How does an ACH transfer work?
ACH payments don't travel directly from one bank to another. Instead, they go through a central operator (either the Federal Reserve or The Clearing House Payments Company) which acts as a middleman between the sending and receiving banks.
Here's how the process works.
Step 1: Initiation
The originator submits a payment instruction to their bank, known as the Originating Depository Financial Institution (ODFI).
Step 2: Batching
The ODFI groups the payment with others and sends the batch to an ACH operator at set intervals throughout the day.
Step 3: Processing
The ACH operator sorts the transactions and forwards them to the Receiving Depository Financial Institution (RDFI).
Step 4: Settlement
The RDFI credits or debits the recipient's account, and the payment is complete.
This batch model is why ACH transfers are not instant. Every payment waits for the next processing window before it moves.
The upside is cost: because multiple payments travel together, the per-transaction fee stays low. That makes ACH one of the most affordable ways to move money within the US.
How long does an ACH transfer take?
A standard ACH transfer typically takes 1–3 business days to complete. The exact time depends on when you submit the payment, the type of transfer, and the receiving bank's processing schedule.
Same-day ACH is also available for an additional fee. These payments are processed on the same business day, provided you submit before the cut-off time.
Three things can slow a transfer down:
Submitting after the bank's daily cut-off time
Weekends and US public holidays
The receiving bank holding funds before releasing them

How much does an ACH transfer cost?
For domestic transfers within the US, ACH is one of the cheapest ways to move money.
Sending and receiving payroll, direct deposits, and bill payments are usually free or carry a very small flat fee. In most cases, it's the sender, not the receiver, who pays the origination fee.
If a business uses a third-party payment processor to initiate ACH payments, that processor typically charges a small fee per transaction. These fees are set by the processor, not by the ACH network itself.
For Malaysian businesses, the real cost rarely comes from the ACH fee. It comes from what happens next: converting the US dollars you received into ringgit. Banks and payment processors often apply exchange rate markups on top of the base FX rate, and those markups can be far larger than any ACH origination fee.
International ACH transfers also tend to cost more than domestic ones. If you're paying a US supplier from Malaysia, your provider will typically charge a conversion fee and, depending on the route, a transfer fee on top.
See What are foreign transaction fees? for a breakdown of how exchange rate markups work and what Malaysian banks typically charge.
ACH transfer vs wire transfer: What's the difference?
Both ACH and wire transfers move money electronically between banks, but they work differently and suit different needs. Here's a quick comparison.
ACH Transfer | Wire Transfer | |
|---|---|---|
Speed | 1–3 business days (same-day for a fee) | Usually same day, sometimes within hours |
Cost | Low or free for domestic transfers | Higher fees, especially for international |
Reversibility | Can be reversed in cases of error or fraud | Generally irreversible once sent |
Best for | Payroll, recurring payments, lower-value transfers | Urgent, high-value, or one-off payments |
Reach | Primarily domestic US transfers | Domestic and international |
The information in this table has been reviewed to be accurate as of 18 June 2026.
The key trade-off is speed versus cost. ACH is cheaper but slower. Wire transfers are faster but carry higher fees and are usually irreversible once sent.

Does Malaysia use ACH?
No. Malaysia does not use the US ACH network. We have our own domestic payment systems built specifically for ringgit transfers between Malaysian bank accounts:
DuitNow — real-time transfers using a mobile number, NRIC, or Business Registration Number
IBG (Interbank GIRO) — batch-processed interbank transfers, typically clearing within the same day or next business day
RENTAS — high-value, time-critical transfers between financial institutions
FPX — an online payment gateway for direct bank-to-merchant payments at checkout
These serve the same general purpose as ACH within Malaysia: moving money electronically between accounts. But they run on entirely separate infrastructure and are MYR-only.
The bottom line? You don't need ACH for domestic Malaysian transfers. You only encounter it when dealing with the US financial system.
What is an international ACH transfer?
The ACH network was designed for domestic US payments, but it can also process cross-border transactions.
An international ACH transfer — sometimes called a global ACH — moves money from a US bank account to an overseas bank account by connecting the US ACH network with the local payment rails in the destination country.
From the recipient's side, the payment arrives like a domestic bank transfer:
The US bank routes the payment through the ACH network
The ACH network connects to the clearing system in the destination country.
The recipient receives funds in their local currency.
Not all banks support international ACH. Before relying on it, confirm with your provider whether they can send or receive ACH payments to or from the US.
What is an International ACH Transaction (IAT)?
You may also come across the term IAT — International ACH Transaction. This refers to a reporting requirement that banks must follow when processing cross-border ACH payments. It happens in the background and has no impact on how you send or receive money.
When would a Malaysian business encounter ACH?
Most Malaysian businesses first encounter ACH when money starts flowing between them and US-based clients, platforms, or contractors. Here are the three most common scenarios:
Scenario 1: Receiving payouts from US platforms
If you sell on US marketplaces, work through US freelance platforms, or receive revenue from a US-based software company, your payout may originate as an ACH credit. The platform sends funds to a US bank account, which means you need a way to receive them.
Scenario 2: Being paid by a US client
When a US company pays your invoice through their bank, they often initiate an ACH transfer. From their end, it's a standard domestic payment. From your end, receiving it requires either a US bank account or a fintech platform with US banking infrastructure.
Scenario 3: Paying a US supplier or contractor
If you pay a US-based supplier, freelancer, or service provider, your payment may need to arrive as an ACH credit in their US bank account. Not all Malaysian banks can originate this directly.
In all three scenarios, the challenge is the same: a standard Malaysian bank account isn't set up for US ACH. You need either a US bank account or a fintech platform to bridge the gap.
How to receive ACH payments as a Malaysian business
If a US client or platform wants to pay you via ACH, you have three main options:
Option 1: Open a US bank account
A US business bank account gives you a local routing number and account number — the details a US payer needs to initiate an ACH transfer.
The downside is complexity: opening a US account as a foreign business typically requires a US address, a registered US entity, and significant paperwork.
Option 2: Use a payment processor
Some payment processors accept ACH on your behalf and pay out to your Malaysian bank account. This removes the need for a US account but adds processing fees and conversion costs along the way.
Option 3: Use a fintech platform with US banking details
This is the most practical option for most Malaysian businesses. Some fintech platforms give you a USD account with a real US routing number and account number. Your US clients send the payment like a standard domestic transfer.
With Airwallex, for example, you get a USD Global Account that comes with a US routing number and account number.
Your US clients can pay you via ACH as if it were a local transfer — no US bank account required. You receive the funds in USD, hold them, and convert to ringgit at competitive rates when you're ready.

Why Malaysian businesses choose Airwallex for USD payments
Setting up a US bank account is slow, expensive, and often requires a registered US entity. Most Malaysian businesses don't have one, and you shouldn't need one just to get paid by a US client.
That's where Airwallex comes in:
A USD account with real US banking details
Airwallex Global Accounts give you a USD account with a US routing number and account number. Your US clients pay you exactly as they would any US supplier, via ACH. You receive the funds directly, with no SWIFT fees and no intermediary banks taking a cut along the way.
Hold, convert, and pay on your terms
You don't have to convert USD to ringgit the moment funds arrive. With Airwallex, you hold your USD balance and convert when the rate works for you. When you do convert, you get competitive FX rates without the markups that Malaysian banks typically add, saving you up to 80% on FX fees.
Pay overseas from the same account
Airwallex isn't just for receiving. You can pay US contractors, suppliers, and platforms directly from your USD balance, without converting to ringgit first and back again. That saves you two rounds of conversions, and eliminates unnecessary FX fees.
Frequently asked questions (FAQs)
Is ACH transfer available in Malaysia?
The ACH network is a US-based system and is not directly available in Malaysia. Malaysian businesses encounter ACH when dealing with US clients, platforms, or contractors — not for domestic ringgit transfers.
Can I receive an ACH payment in my Malaysian bank account?
Most Malaysian bank accounts cannot directly receive US ACH payments. You typically need a US bank account or a fintech platform that provides US banking details. Airwallex Global Accounts give you a USD account with a real US routing number so you can receive ACH payments without a US bank account.
What details do I need to receive an ACH payment?
To receive an ACH payment, you need a US routing number and a US account number. These are the standard details any US payer will ask for before initiating a transfer.
What is the difference between ACH and a wire transfer?
ACH transfers are batch-processed, typically take 1–3 business days, and are low cost. Wire transfers are processed individually, are usually faster, and carry higher fees. See our wire transfer guide for a full comparison.
Is ACH transfer safe?
Yes. The ACH network is regulated by NACHA and monitored by the US Federal Reserve. ACH debits can be reversed in cases of error or fraud, which offers an added layer of protection compared to wire transfers.
Do I pay tax on ACH payments received in Malaysia?
ACH is a payment method, not a separate income category. Whether you owe tax on funds received depends on your business structure and the nature of the income. Speak to a Malaysian tax adviser for guidance specific to your situation.
