Payment Gateways in Singapore: Stripe, PayNow, GrabPay and More for E-commerce

Singapore’s E-commerce Payment Landscape

Choosing the right payment gateways Singapore ecommerce setup is fundamental to maximising your online revenue. Singapore shoppers expect multiple payment options at checkout, and offering only credit cards means leaving money on the table. Research shows that 60 to 70 percent of cart abandonments in Southeast Asia are related to payment friction, whether from limited payment options, complicated checkout flows or trust concerns.

The Singapore market has several distinctive characteristics that shape payment strategy. Credit and debit cards remain the most popular online payment method, accounting for roughly 45 percent of e-commerce transactions. However, digital wallets and alternative payment methods are growing rapidly. PayNow has become ubiquitous for peer-to-peer transfers and is increasingly used in e-commerce. GrabPay benefits from Grab’s massive user base. Buy Now Pay Later services have captured a significant share of younger shoppers.

Your payment setup affects more than just transactions. It influences your digital marketing performance because checkout friction directly impacts your return on ad spend. Every additional payment option you offer can increase conversion rates by 5 to 15 percent, depending on your audience demographics.

This guide compares the major payment gateways and methods available for Singapore e-commerce businesses, covering fees, features, integration complexity and suitability for different business models.

Credit Card Payment Gateways

Credit card processing forms the backbone of most Singapore e-commerce payment stacks. Several gateways compete for market share, each with distinct strengths.

Stripe is the preferred choice for technology-forward businesses. Its developer-friendly APIs, comprehensive documentation and modern dashboard make integration straightforward. Stripe supports Visa, Mastercard, American Express and JCB. Transaction fees are 3.4 percent plus SGD 0.50 per successful charge for domestic cards and 3.9 percent plus SGD 0.50 for international cards. Stripe also supports PayNow, GrabPay and Alipay through its platform, simplifying your integration.

PayPal Braintree offers a full-stack payment platform with credit card processing, PayPal and digital wallet support. It is well-suited for businesses that sell internationally, as PayPal is trusted globally. Fees are competitive at around 3.9 percent plus a fixed fee for cross-border transactions.

Adyen serves larger e-commerce operations and offers a unified platform for online, mobile and in-store payments. Its risk management tools and global acquiring capabilities make it popular with enterprise brands. Pricing is interchange-plus, which can be more cost-effective at high volumes.

For businesses on Shopify, the built-in Shopify Payments (powered by Stripe) offers the simplest setup with competitive rates and no additional gateway fees. WooCommerce users can choose from dozens of gateway plugins, with Stripe and PayPal being the most popular.

HitPay is a Singapore-based payment platform designed for local businesses. It supports credit cards, PayNow, GrabPay and other local methods with a simple integration. Their no-code payment links and point-of-sale features suit businesses that sell both online and offline.

Local Payment Methods: PayNow, GrabPay and More

Local payment methods are essential for capturing the full spectrum of Singapore shoppers. Not everyone prefers credit cards, and some customers actively seek alternatives.

PayNow is Singapore’s real-time payment system linked to mobile numbers, NRIC or UEN. For e-commerce, PayNow QR codes can be generated at checkout for customers to scan and pay instantly. The key advantage is low cost, with many providers charging less than one percent per transaction. The limitation is that PayNow payments require manual or semi-automated reconciliation unless your gateway handles it natively. Stripe, HitPay and Omise support PayNow integration with automated reconciliation.

GrabPay leverages Grab’s extensive user base in Singapore. Integration is available through Stripe, Adyen and direct integration via the GrabPay API. Transaction fees are typically around 2 to 3 percent. GrabPay is especially popular for food, groceries and everyday purchases, making it valuable for these product categories.

ShopeePay is relevant if you sell on Shopee or want to attract Shopee’s user base to your own website. Its adoption is growing but remains primarily marketplace-focused.

Bank transfers via FAST (Fast And Secure Transfers) offer another option, particularly for high-value purchases where customers prefer direct bank-to-bank payment. Some businesses provide FAST transfer details at checkout with order reference numbers for reconciliation.

For cross-border sales to Chinese tourists and residents, Alipay and WeChat Pay integration captures a valuable customer segment. Stripe and Adyen both support these payment methods. When running Google Ads campaigns targeting Chinese-speaking audiences in Singapore, offering these payment methods at checkout improves conversion.

Buy Now Pay Later Options

Buy Now Pay Later (BNPL) services have reshaped Singapore’s e-commerce payment landscape, particularly for fashion, electronics and lifestyle categories. BNPL providers pay you upfront and collect from the customer in instalments, shifting the credit risk away from your business.

Atome offers three interest-free instalments and has strong brand recognition in Singapore. It integrates with Shopify, WooCommerce and custom platforms. Merchant fees are typically 4 to 6 percent of the transaction value, higher than credit cards but offset by increased average order values and conversion rates. Atome users spend 30 to 50 percent more per order compared to non-BNPL checkouts.

Pace (formerly Rely) provides three interest-free payments and focuses on lifestyle and retail brands. Their in-store and online solutions make them suitable for omnichannel businesses.

Grab PayLater integrates with GrabPay and allows customers to split purchases into four instalments. Its integration with the Grab ecosystem gives it a large potential user base.

When deciding whether to offer BNPL, consider your product price range and target audience. BNPL adoption is highest for purchases between SGD 100 and SGD 500 among consumers aged 25 to 40. If your average order value falls within this range, BNPL can meaningfully increase conversions. Factor the higher merchant fees into your pricing and margin calculations.

Display BNPL availability prominently on product pages and in your social media marketing to attract BNPL-savvy shoppers. Messaging like “Pay in 3 instalments from SGD X/month” on product listings and ads reduces perceived price barriers.

Fees and Cost Comparison

Payment processing fees directly affect your margins. Understanding the full cost structure helps you choose the right mix of payment methods.

Credit card processing through Stripe costs 3.4 percent plus SGD 0.50 per transaction for domestic cards. For a SGD 50 order, that is SGD 2.20 or 4.4 percent of the order value. For a SGD 200 order, the effective rate drops to 3.65 percent. The fixed fee component means credit card processing is proportionally more expensive for low-value orders.

PayNow costs between 0.5 and 1 percent through most providers, making it the cheapest digital payment method. For low-margin or low-value products, encouraging PayNow payments can meaningfully improve profitability. Some providers offer PayNow with zero transaction fees on certain plans.

GrabPay fees range from 2 to 3 percent depending on your provider and volume. This positions it between PayNow and credit cards in terms of cost.

BNPL services charge 4 to 7 percent, the highest among payment methods. However, the lift in conversion rates and average order value often produces a positive return despite the higher fees. Calculate your net contribution margin with and without BNPL to determine if the trade-off works for your business.

Beyond transaction fees, watch for monthly fees, setup fees, chargeback fees and payout timing. Stripe pays out on a rolling basis with a two to seven business day delay. Some local gateways offer next-day settlement, which benefits cash flow. Chargeback fees are typically SGD 15 to SGD 25 per dispute regardless of outcome.

For businesses processing more than SGD 50,000 per month, negotiate custom rates with your gateway provider. Volume discounts of 0.2 to 0.5 percent are common and can save thousands annually.

Integration and Technical Setup

The technical integration of payment gateways ranges from plug-and-play to complex custom development. Choose based on your platform and technical resources.

For Shopify stores, enable Shopify Payments for credit cards, then add PayNow and GrabPay through approved payment apps. Atome and Pace offer Shopify apps for one-click installation. The entire setup can be completed in an afternoon without developer involvement.

WooCommerce users install gateway plugins from the WordPress plugin directory. Stripe’s official WooCommerce plugin supports credit cards, PayNow and GrabPay. BNPL providers offer dedicated WooCommerce plugins. Test thoroughly in sandbox mode before going live, as plugin conflicts are common in WordPress environments.

Custom-built websites require API integration. Stripe’s API is well-documented with libraries for PHP, Node.js, Python and other languages. Implement webhooks to receive real-time payment notifications and update order status automatically. Use Stripe Checkout or Stripe Elements for pre-built, PCI-compliant payment forms that reduce your compliance burden.

Regardless of your platform, test every payment method end-to-end before launch. Process test transactions, verify that order confirmations trigger correctly, check that refunds process smoothly and confirm that your accounting system receives accurate data. Payment integration issues discovered after launch cost you real revenue.

Your web design should present payment options clearly at checkout. Display all accepted payment logos in the footer and on product pages. Show the customer’s preferred payment method first based on their previous purchases or detected device. A well-designed checkout page with clear payment options reduces abandonment.

Security and Compliance

Payment security is non-negotiable for e-commerce businesses. Singapore’s regulatory environment requires adherence to specific standards and regulations.

PCI DSS (Payment Card Industry Data Security Standard) compliance is mandatory if you process, store or transmit credit card data. Using hosted payment forms from Stripe, Braintree or Adyen means the card data never touches your servers, significantly reducing your PCI compliance scope. You still need to complete a Self-Assessment Questionnaire (SAQ A) annually.

The Payment Services Act (PSA) regulates payment service providers in Singapore under the Monetary Authority of Singapore (MAS). If you operate as a payment facilitator or hold customer funds, you may need a licence. Most e-commerce businesses using third-party gateways are not directly regulated, but understand the implications if you handle stored-value accounts or money transfers.

3D Secure (3DS) authentication adds a verification step during checkout where the customer’s bank confirms the transaction. While it adds friction, 3DS shifts chargeback liability from the merchant to the card issuer for authenticated transactions. Stripe and most gateways support 3DS with smart authentication that only triggers the additional step for high-risk transactions.

Fraud prevention tools built into payment gateways analyse transactions for suspicious patterns. Stripe Radar uses machine learning to block fraudulent transactions automatically. Configure your fraud rules based on your business context, for example blocking orders from high-risk countries if you only ship domestically, or flagging orders where billing and shipping addresses differ significantly.

Implement tokenisation for returning customers so they can pay with saved cards without you storing actual card numbers. This improves the checkout experience while maintaining security. Combined with strong returns and refund policies, secure payments build the trust needed for repeat purchases.

Frequently Asked Questions

What is the best payment gateway for small e-commerce businesses in Singapore?

Stripe offers the best combination of ease of integration, feature set and cost for most small businesses. It supports credit cards, PayNow, GrabPay and international payment methods from a single platform. If you are on Shopify, use Shopify Payments which is powered by Stripe. HitPay is another strong option for businesses that also sell offline.

How much do payment gateway fees cost in Singapore?

Credit card processing typically costs 3.4 to 3.9 percent plus a fixed fee per transaction. PayNow costs 0.5 to 1 percent. GrabPay costs 2 to 3 percent. BNPL services charge 4 to 7 percent. Most gateways have no monthly fees for basic plans, though some charge monthly subscription fees for premium features.

Should I offer PayNow on my e-commerce website?

Yes. PayNow is widely adopted in Singapore, has the lowest processing fees among digital payment methods and builds trust with customers who prefer bank-linked payments over credit cards. The main consideration is ensuring your integration handles automated reconciliation so you do not need to manually match payments to orders.

Is Buy Now Pay Later worth the higher merchant fees?

For most consumer e-commerce businesses with average order values above SGD 80, BNPL services generate enough incremental revenue through higher conversion rates and larger order values to offset the higher fees. Test BNPL for 60 to 90 days and measure the net impact on revenue and margins before committing long term.

How do I accept payments from international customers?

Use a gateway that supports multi-currency processing like Stripe or Adyen. Display prices in the customer’s local currency where possible. Accept international cards, PayPal and region-specific methods like Alipay for Chinese customers. Factor in higher cross-border processing fees of 3.9 to 4.5 percent when pricing international orders.

What payment methods should I offer at minimum?

At minimum, offer credit and debit cards (Visa and Mastercard), PayNow and one BNPL option. This covers the needs of most Singapore shoppers. Add GrabPay and American Express if your customer data shows demand. Each additional payment method you add increases checkout conversion, but there are diminishing returns beyond four to five options.

How do I handle chargebacks and payment disputes?

Respond to chargebacks within the deadline set by your gateway, typically seven to 21 days. Provide evidence including delivery confirmation, customer communication and order details. Use 3D Secure to shift liability for card-present fraud. Implement clear refund policies and responsive customer service to resolve disputes before they become chargebacks.

Can I use multiple payment gateways simultaneously?

Yes. Many businesses use Stripe for credit cards and PayNow while adding separate integrations for BNPL providers. This approach lets you use the best provider for each payment method. Ensure your order management system reconciles payments from all sources and that your reporting captures the full picture across gateways.
