How to pay overseas suppliers from Singapore (2026 guide)

Key Takeaways:

• Paying overseas suppliers from Singapore involves more than choosing the fastest option. The payment method you choose affects your fees, your FX costs, and how protected you are if something goes wrong.

• The transfer fee is rarely the biggest cost. The FX markup hidden in the exchange rate is usually larger, and it compounds across every recurring payment.

• Airwallex Transfers lets you send payments to 120+ countries via local payment rails with $0 transfer fees. Our FX is competitively priced at 0.4% to 0.6% above interbank, saving you up to 80% on FX fees compared to traditional banks.

Paying overseas suppliers from Singapore is something most businesses figure out under pressure: the first invoice arrives, and suddenly you need to decide how to send money abroad quickly and cheaply.

This guide covers the main payment methods available to Singapore businesses, what to consider when choosing between them, and how to run the payment process in a way that protects your business.

What to consider before paying an overseas supplier

Before comparing payment methods, here are four things to consider.

Currency of payment

Start by asking your supplier which currency they want to receive. If they invoice you in USD, for example, you’ll need to send USD even if your business holds its funds in SGD.

That means converting your SGD to USD before making the payment. How much that conversion costs depends on the exchange rate and FX markup charged by your bank or payment provider. This brings us to our next point…

Transfer fees and FX markup

International payments usually come with two main costs: the transfer fee and the FX markup. The transfer fee is easy to spot because it appears as a separate charge.

The FX markup is less obvious, because it’s built into the exchange rate you get.

Looking for a provider with a low FX markup? Airwallex offers highly competitive rates of 0.4% to 0.6% above interbank, which lets you save up to 80% on FX fees as compared to traditional banks.

Frequency and volume

A one-off payment to a new supplier is very different from making weekly payments to suppliers across ten countries.

If you make regular, high-volume payments, look for a provider that supports batch and scheduled transfers. Entering every payment manually takes time and leaves more room for errors.

Payment speed

SWIFT transfers can take two to five business days, while payments sent through local payment rails can often arrive the same day. If your supplier won't ship until payment clears, the speed of your payment can have a direct impact on your supply chain.

Payment methods for paying overseas suppliers from Singapore

There are several ways to pay overseas suppliers from Singapore, and each comes with different trade-offs in cost, speed, and buyer protection. Here’s a quick overview:

For a breakdown of how fees compare across specific providers, see our guide to international money transfer fees.

Option 1: Bank wire transfer (SWIFT / telegraphic transfer)

A bank wire transfer (also called a telegraphic transfer or TT in Singapore) sends money from your bank account to your supplier’s bank account through the SWIFT network.

The payment may pass through one or more intermediary banks, which can deduct fees before the money reaches your supplier.

Bank wires are widely accepted and generally support high transaction amounts, making them suitable for large invoices. The trade-off is that they can be slower and more expensive than local payment methods.

Singapore banks typically charge a fee for each outward transfer, while FX costs are built into the exchange rate. Intermediary bank charges may also reduce the amount your supplier receives.

Best used when: you’re paying a large invoice to an established supplier and want a bank-backed payment trail.

Option 2: Multi-currency business account

A multi-currency business account lets you hold funds in multiple currencies, convert between them, and pay suppliers directly in the currency they invoice you in.

When the payment can be sent through local payment rails instead of SWIFT, it can arrive faster and avoid international wire fees.

This can be a practical option for businesses making regular overseas payments. If you’re paying suppliers in several currencies, holding those currencies and using local payment rails can help reduce the costs associated with repeated FX conversions and international wires.

Best used when: you make regular payments across multiple currencies and want more control over your FX and transfer costs.

Option 3: Peer-to-peer (P2P) transfer platforms

P2P platforms such as PayPal let individuals and some businesses send money through a third-party platform rather than directly through a bank.

They can be convenient for smaller payments, such as samples or one-off purchases, particularly when the platform offers some form of buyer protection.

For regular supplier payments, however, P2P platforms may have lower transfer limits and fewer business-focused features, such as batch payments or accounting integrations. Fees can also vary depending on the currency and payment method.

Best used when: you’re making a small, one-off payment and convenience or buyer protection is more important than keeping costs as low as possible.

Option 4: Corporate card

A corporate card can be useful for smaller overseas expenses, such as software subscriptions, advertising spend in foreign currencies, or supplier samples purchased online. Some suppliers also accept cards for deposits or smaller orders.

For larger manufacturing invoices, cards are generally less suitable. Transaction limits may be lower than for bank transfers, suppliers may charge a card processing fee, and the FX rate may be less competitive than other business payment options.

Best used when: you’re covering smaller business expenses in foreign currencies and the convenience or card rewards justify the cost.

Option 5: Escrow / trade platform

Escrow-style payment services, such as Alibaba Trade Assurance, hold your payment under agreed terms and provide a dispute process if the supplier does not meet those terms. This can provide additional protection when you’re dealing with a supplier for the first time.

The limitation is that this protection is tied to the platform. For example, Alibaba Trade Assurance applies to eligible purchases made through Alibaba, rather than payments you make directly to a supplier outside the platform. Fees also vary depending on the payment method.

Best used when: you’re placing a first order through a trade platform and want additional protection if the supplier doesn’t meet the agreed terms.

Option 6: Letter of Credit

A Letter of Credit (L/C) is a payment arrangement where your bank commits to paying the supplier once the supplier presents the documents specified in the agreement.

This can give both sides greater assurance that payment will only be made when the agreed documentary conditions are met.

Letters of Credit involve both banks and require detailed terms and documentation. Bank fees can apply on both sides, and the process can take time to arrange. For smaller or routine orders, that administrative work may not be worthwhile.

Best used when: you’re placing a large, high-value order and both you and your supplier want formal bank-backed payment terms.

How to protect your business when paying overseas suppliers

International wire transfers can be difficult to reverse once sent. If something goes wrong, recovering the money may not be possible. These steps can help reduce the risk.

Verify account details separately

If a supplier sends you new bank details by email, WhatsApp, or another digital channel, confirm them directly with the supplier before making the payment. Business email compromise (BEC) scams can involve fraudsters impersonating suppliers and sending fake payment instructions.

Use a phone number or contact you have verified independently rather than replying to the same message that contained the new account details.

Pay the supplier’s business account

Where possible, pay into an account held in the supplier’s business name. If a supplier asks you to pay a personal account, particularly for a first order, ask why and verify the arrangement before sending the money.

Agree on payment terms upfront

Avoid paying 100% upfront when working with a supplier for the first time. A deposit before production followed by the balance before shipment can limit your exposure if something goes wrong.

Inspect before paying the balance

If you’re paying a deposit followed by the balance, consider arranging a pre-shipment inspection before releasing the final payment. This gives you a chance to check the goods before the remaining funds are sent and the order leaves the factory.

How to pay an overseas supplier from Singapore: step by step

Once you’ve chosen a payment method and verified your supplier’s details, follow the same basic steps for each payment.

Step 1: Confirm the invoice and bank details

Check the invoice currency, amount due, beneficiary name and account number, and payment deadline. Make sure the payment currency matches the invoice currency.

If they don’t match, the receiving bank may convert the payment or reject it.

Step 2: Match the invoice to your purchase order

Before making the payment, check the invoice against your purchase order or contract. Account for any deposit already paid, changes in quantity or pricing, and the remaining balance. Resolve any differences before proceeding.

Step 3: Check whether local payment rails are available

Whether you can use local payment rails depends on the supplier’s country, bank, and payment currency. Local rails can be faster and may cost less than SWIFT, but the supplier’s account and currency must be supported. Check this before comparing payment options.

Airwallex offers free transfers via local rails in 120+ countries, with $0 transfer fees. 93% of our transfers arrive on the same day, and 45% arrive immediately.

Step 4: Compare the total cost

Don’t compare providers based on the transfer fee alone. Look at the total amount you’ll pay, the exchange rate, any additional fees, and the amount your supplier will receive. This gives you a more accurate basis for comparing providers.

Step 5: Get approval for new or high-value payments

For a new supplier, a large invoice, or a new beneficiary account, consider requiring a second person to approve the payment before it is sent.

Step 6: Send the payment and confirm receipt

Include the invoice reference when making the payment and send the remittance confirmation to your supplier. Ask them to confirm that the expected amount has arrived.

If they receive less than expected, check whether intermediary bank fees were deducted before sending any additional funds. This helps avoid paying twice for the same shortfall.

Frequently asked questions (FAQs)

What is the cheapest way to pay overseas suppliers from Singapore?

For most businesses making regular overseas payments, a multi-currency business account that uses local payment rails is the lowest-cost option overall. The transfer fee is only part of the picture; the FX markup applied to the exchange rate is usually the larger cost, and it applies to every payment. For a side-by-side comparison of specific providers, see our guide to international money transfer services in Singapore.

Should I pay overseas suppliers in SGD or their local currency?

Pay your supplier in the currency they invoice you in. If they invoice you in USD, for example, you have two options:

• Convert SGD to USD when making the payment: Your provider converts the funds as part of the transfer and applies its exchange rate and FX markup.

• Hold USD in a multi-currency account: Convert your SGD to USD upfront, then pay the supplier directly from your USD balance.

The second option can be cheaper and more transparent, because you can see and manage your FX costs separately from the transfer.

How do I avoid getting scammed when paying overseas suppliers?

The most common risk is business email compromise, where fraudsters intercept supplier communications and substitute their own bank details. Always verify changed payment instructions by calling your supplier directly on a number you have independently confirmed. Only pay registered business bank accounts, not personal ones. For first orders with unverified suppliers, escrow tools like Alibaba Trade Assurance give you a formal dispute mechanism before you commit to direct bank transfers.

What bank details do I need to pay an overseas supplier?

For a SWIFT transfer, you typically need your supplier's full legal business name, their bank name and branch address, their SWIFT or BIC code, and their local routing code (such as a CNAPS code for China, a BSB for Australia, or a sort code for the UK). For payments via local rails, requirements vary by country. Your payment provider will prompt you for the specific fields needed for each destination.

How do I pay overseas suppliers in China from Singapore?

Paying Chinese suppliers involves a few China-specific considerations: including whether to pay in CNY, CNH or USD, how to handle CNAPS codes, and when to use Alibaba Trade Assurance versus a direct bank transfer. Our guide to paying Chinese suppliers from Singapore covers all of this in detail. If you're also looking to source suppliers in China, our guide to finding reliable Chinese suppliers is a good starting point.

How long does it take to pay an overseas supplier from Singapore?

It depends on the payment method and the destination. Payments via local payment rails typically arrive the same day. SWIFT transfers take two to five business days, and sometimes longer if the payment passes through multiple correspondent banks. If you’re looking for fast, fuss-free transfers, use Airwallex. 93% of our transfers arrive on the same day, and 45% arrive immediately.
