7 best payment gateways for Shopify Singapore (2026)

Key Takeaways:

• Shopify Payments is available in Singapore but doesn't natively support PayNow, so most Singapore merchants end up adding a third-party gateway anyway.

• When you use a third-party gateway, Shopify charges an extra transaction fee on every sale on top of your gateway's own processing fee.

• Airwallex connects directly to your Shopify store, supports PayNow and GrabPay alongside 160+ local payment methods, and settles like-for-like in 14 currencies — so you don't incur unnecessary FX fees on every international sale.

Picking the best payment gateway for your Shopify store in Singapore matters more once your sales start to grow.

At low volumes, almost any gateway works fine. Once you're processing real revenue — or selling to customers outside Singapore — every fee on every order starts to add up.

This article breaks down the seven gateways most relevant to Singapore Shopify merchants. You'll see what each one actually costs at different sales volumes, which local and international payment methods they support, and how they handle multi-currency settlement.

7 best payment gateways for Shopify in Singapore

Here are the seven gateways most relevant to Singapore Shopify merchants in 2026.

Use the table below for a quick scan, then read the breakdowns for the providers you're shortlisting:

Rates and features above are accurate as of 20 May 2026.

1. Shopify Payments

Shopify Payments is the default gateway built into Shopify. It's the only gateway that waives Shopify's third-party transaction fee, which makes it the cheapest option on paper — especially if you sell mostly to Singapore customers in SGD.

The catch is on cross-border sales. Shopify Payments converts every non-SGD payment to SGD before paying you out, and applies a currency conversion fee on top of the card rate. That fee isn't published clearly on Shopify's pricing page, but it adds to your total cost on every international order. It also doesn't natively support PayNow, GrabPay, or ShopeePay in Singapore.²

2. Airwallex

Airwallex is a payment and financial platform built for businesses that move money across borders. On Shopify, it works as a third-party gateway and brings two things most others don't: like-for-like settlement in 14 currencies, and a multi-currency account that holds the funds in their original currency until you decide what to do with them.

For a Singapore store selling overseas, that changes the cost equation entirely. A USD sale lands in your USD wallet untouched. You convert to SGD only if and when you choose to. If you hold the USD to pay for your US software or ad spend, you can avoid FX fees completely.

Airwallex charges 3.3% + S$0.50 on domestic cards and adds 0.3% on international cards. It supports PayNow, GrabPay, Alipay, WeChat Pay, and major BNPL options. It's a Major Payment Institution licensed by the Monetary Authority of Singapore.

3. Stripe

Stripe is one of the most widely used international gateways, with a strong developer ecosystem and broad payment-method coverage. On Shopify in Singapore, it accepts cards plus PayNow (1.3%), GrabPay (3.3%), Alipay (2.2% + S$0.35), and WeChat Pay (2.2% + S$0.35).³

The cost story is mixed. Stripe charges 3.4% + S$0.50 on domestic SG cards.³ For cross-border, it adds an extra 0.5% for international cards and a 2% currency conversion fee whenever the payment currency differs from your settlement currency.³

At higher volumes those FX charges become the largest line item — Stripe doesn't offer like-for-like multi-currency settlement to merchants in Singapore by default.

4. PayPal

PayPal's strength on Shopify is buyer trust. Many international shoppers will only check out if they see the PayPal button — which can lift conversion on cross-border sales even when the fees are higher than card rates.

The catch? PayPal’s fees are higher than the other providers on this list. The standard rate for receiving domestic commercial transactions in Singapore is 3.9% + S$0.50.⁵ For international receipts, it's 4.4% + the fixed fee.⁵

On FX, PayPal applies a 3% margin over the base exchange rate when converting payments received into another currency for sellers in Singapore, and 4% when sending payments or processing refunds.⁵ Like Shopify Payments and Stripe, PayPal does not offer like-for-like multi-currency settlement to Singapore sellers by default.

5. Adyen

Adyen is an enterprise-grade gateway used by large global brands. On Shopify, it integrates as a third-party gateway and is generally a fit for higher-volume merchants who want one platform handling online, in-store, and global card processing.

Pricing uses Interchange++: you pay the actual interchange fee charged by the card network, plus Adyen's processing fee of US$0.13 + 0.60% per transaction.⁶ This can work out cheaper than flat-rate gateways at scale, but it's only worth it if you understand interchange rates and have the volume to justify the complexity.

Adyen doesn't publish setup or monthly fees, but it does require a minimum monthly invoice that varies by industry or business model.⁶ That's the catch for smaller stores — if you don't process enough volume to hit the minimum, you're paying for capacity you're not using.

6. HitPay

HitPay is a Singapore-based gateway built for local SMEs. It has the strongest set of Singapore payment methods of any provider on this list — PayNow, GrabPay, ShopeePay, Atome, Grab PayLater, ShopeePay Later, and WeChat Pay all supported on its Shopify integration.⁴

Pricing is straightforward. Online domestic cards are 2.8% + S$0.50, international cards are 3.65% + S$0.50, and a 2% fee applies to foreign currency transactions.⁴ PayNow is 0.65% + S$0.30 for transactions of S$100 or more, or 0.9% (minimum S$0.20) below S$100.⁴ There are no setup or monthly fees.⁴

Note that when used as a Shopify integration, HitPay charges an additional 0.5% on top of its standard payment fees.⁴ Like Shopify Payments and Stripe, HitPay does not offer like-for-like multi-currency settlement — foreign currency payments are converted to SGD before payout.

7. FomoPay

FomoPay is a Singapore-headquartered payments company, MAS-licensed in Singapore and also licensed in Hong Kong and the UAE.⁷ It's been operating for over 11 years and reports trusted use by 5,000+ companies globally.⁷

FomoPay doesn't publish standard pricing publicly. Rates are quoted per merchant based on volume, industry, and integration scope. That makes it a fit for established stores that can negotiate pricing — and a poor fit for starter stores that want to see fees before committing.

On Shopify, FomoPay supports local Asian payment methods including PayNow, WeChat Pay, and Alipay. Multi-currency settlement is available but depends on the specific commercial agreement, so confirm coverage and FX terms during onboarding.

How Shopify payment gateway fees work at higher volumes

Most comparison articles treat payment gateway fees as a single number. On Shopify, you're actually paying two fees that both shift as you upgrade your plan — and they don't shift at the same rate.

Understanding how they interact is crucial to picking the right gateway.

Two fees apply on every non-Shopify Payments transaction

If you use Shopify Payments, you pay one fee: the card processing rate. If you use any other gateway, you pay two:

• The gateway's own processing fee, set by the provider — for example, 3.4% + S$0.50 for Stripe³

• Shopify's third-party transaction fee, set by Shopify and based on your plan

The second fee is what makes third-party gateways look expensive on starter plans. On Basic, you're paying Stripe around 3.4% plus Shopify another 2% — close to 5.4% before any FX cost.

Both fees shrink as you upgrade

Here's how Shopify's fees move across plans for a domestic SGD card sale:

The information in this table has been reviewed to be accurate as of 20 May 2026.

Two things stand out.

First, Shopify Payments' card rate only drops 0.3 percentage points across all four plans, while the third-party transaction fee drops 1.8 percentage points over the same range. The fee that penalises third-party gateways shrinks much faster than Shopify Payments' own rate.

Second, once you're on Advanced or Plus, the third-party fee is small enough that a cheaper third-party gateway can easily beat Shopify Payments on total cost — especially if the third-party gateway also saves you money on FX.

You can use an external gateway on any plan, including Plus

A common misconception, especially among Plus merchants, is that Shopify Payments is the only option once you're locked into a high-volume contract. That's not the case. Shopify supports certified third-party gateways on every plan, including Plus.

That matters because the merchants with the most to gain from switching are often the ones who assume the switch isn't available to them. The next section shows exactly where the crossover happens.

What to look for in a Shopify payment gateway in Singapore

Before comparing providers, it helps to know what features you should be looking at. Here are four things to consider when evaluating payment gateways:

1. Transaction fees + Shopify's third-party fee

Every gateway charges a percentage plus a small fixed fee per transaction. On Shopify, there's a second fee to factor in: unless you use Shopify Payments, Shopify adds its own third-party transaction fee on top — 2% on Basic, 1% on Grow, 0.6% on Advanced, and 0.2% on Plus.¹

So the headline rate alone won't tell you which gateway is cheapest. Add the two fees together, then layer on any FX cost on your cross-border sales. The cost comparison table above already does this for you across three volume tiers.

2. Support for local payment methods like PayNow and GrabPay

Most Singapore stores need PayNow at a minimum, and GrabPay if you're targeting younger shoppers. Shopify Payments doesn't natively support either in Singapore.²

Of the seven providers above, Airwallex, HitPay, Stripe, and FomoPay all cover the main local methods.

For a deeper breakdown of which payment methods Singapore shoppers expect at checkout, see our guide to payment methods in Singapore.

3. Currency, FX cost, and like-for-like settlement

If you only sell in SGD, this matters less. If 20% or more of your revenue is cross-border, this is usually the single biggest hidden cost in your stack — bigger than the gateway fee itself at scale.

Only Airwallex on this list offers like-for-like settlement in 14 currencies; the others auto-convert to SGD before payout.

4. Shopify compatibility and integration

Check that the gateway has a native Shopify app or plugin rather than custom-only integration. All seven providers covered here have direct Shopify integrations available in Singapore.

Why Singapore businesses choose Airwallex

Shopify Payments works fine if your store sells mainly to Singapore customers in SGD and you don't mind not offering PayNow or GrabPay. For that specific case, it's the cheapest option on the list.

But most Singapore stores don't operate in that narrow lane. The moment you start selling overseas, paying overseas suppliers, running ad spend in USD, or building a team across the region, the cost equation changes — and Shopify Payments is no longer the best fit.

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

Collect payments without losing margin on FX

Most gateways auto-convert every non-SGD payment to SGD before paying you out, at a 1.5–2% FX margin. At S$500,000/year in cross-border sales, that's S$7,500–S$10,000 of margin gone before you've done anything else.

Airwallex settles like-for-like in 14 currencies. A USD sale lands in your USD wallet untouched. You convert only when you choose to, at 0.4–0.6% above interbank — or you skip the conversion entirely and spend the USD directly on US suppliers, software, or ad platforms.

Hold and spend foreign currency natively

Airwallex Global Accounts give you local account details in 20+ currencies. Your overseas customers pay into a local account in their currency, the funds sit in your wallet, and you decide when (or whether) to convert.

That matters because most Shopify stores selling overseas also spend overseas. Holding USD lets you pay your US fulfillment partner, Meta Ads invoice, and SaaS subscriptions in the currency they're billed in, without paying FX fees twice.

Save up to 80% on FX fees when paying overseas suppliers

Airwallex Transfers let you pay suppliers in 200+ countries at FX rates 0.4–0.6% above interbank — that’s up to 80% cheaper than what a bank charges on the same payment.

For a store importing from China, Vietnam, or India, this is often a bigger annual saving than the gateway fees themselves.

Issue cards for ad spend and team expenses

Airwallex Corporate Cards are multi-currency by default. Charge a USD ad spend invoice in USD, a GBP SaaS subscription in GBP, and a SGD office cost in SGD — all from cards funded by your Airwallex wallet. You can issue unlimited cards for staff, set spend limits per card, and see every transaction in real time.

Frequently asked questions (FAQs)

Does Shopify Payments support PayNow in Singapore?

No. Shopify Payments does not natively support PayNow in Singapore.² To accept PayNow on your Shopify store, you'll need to add a third-party gateway that does — Stripe, HitPay, and Airwallex all support it. Shopify will charge its third-party transaction fee on those orders, between 0.2% and 2% depending on your plan.¹

Does Shopify charge transaction fees in Singapore?

Yes. Shopify charges an additional transaction fee on every order processed through a non-Shopify Payments gateway: 2% on Basic, 1% on Grow, 0.6% on Advanced, and 0.2% on Plus.¹ This is on top of your gateway's own processing fee. Only Shopify Payments waives this fee.

Should I switch from Shopify Payments to a third-party gateway?

It depends on your sales mix and your plan. If you sell mainly in SGD on a Basic or Grow plan, Shopify Payments is usually still the cheapest option once you factor in Shopify's 1–2% third-party fee.¹ If you sell internationally — or you're on Advanced or Plus where the third-party fee drops to 0.6% or 0.2%¹ — a gateway like Airwallex that settles in 14 currencies can save more on FX than the Shopify fee adds back.

What's the cheapest payment gateway for Shopify in Singapore?

It depends on the type of order. For domestic SGD card sales, HitPay's published rate of 2.8% + S$0.50 is the lowest on this list,⁴ followed by Shopify Payments at 3.2% + S$0.50 on Basic and 2.9% + S$0.50 on Plus.¹ For PayNow, HitPay charges 0.65% + S$0.30 on transactions of S$100 or more.⁴ Always add Shopify's third-party transaction fee when comparing — it adds 0.2% to 2% on top of any non-Shopify Payments gateway.¹

Can I use two payment gateways on Shopify at the same time?

Yes. A common Singapore setup is to run Shopify Payments for cards and add a second gateway like Airwallex for PayNow, GrabPay, and any international sales you want to settle in non-SGD. This lets you avoid Shopify's third-party fee on your card volume while still offering local methods and protecting margin on cross-border orders.

Do I need to be on Shopify Plus to use a third-party payment gateway?

No. You can use a certified third-party gateway on every Shopify plan, including Basic, Grow, Advanced, and Plus. The only thing that changes by plan is the size of Shopify's third-party transaction fee — from 2% on Basic down to 0.2% on Plus.¹
