Quick Answer: HitPay is the most complete payment gateway for Singapore SMBs in 2026 — it supports PayNow, GrabPay, ShopeePay, Atome, ShopBack PayLater, all major cards, and 10+ cross-border wallets including WeChatPay, UPI, and PromptPay, with no monthly fees, next business day SGD payouts, and MAS licence PS20200643. Stripe and Airwallex are strong alternatives for developer-heavy or globally focused businesses, but neither matches HitPay’s local payment method breadth for Singapore retail and e-commerce SMBs.

Singapore’s payment landscape has changed significantly. Mobile wallet adoption continues to accelerate, with PayNow now embedded across most retail and food & beverage categories — from hawker stalls in Chinatown to boutiques along Orchard Road. According to Monetary Authority of Singapore (MAS), PayNow processed over 1.8 billion transactions in 2023, cementing its status as the backbone of Singapore’s digital payment infrastructure.

For small and medium businesses (SMBs), the gateway choice directly determines which customers can pay, how quickly funds settle, and what reconciliation looks like at end of month. This comparison covers the five most relevant gateways operating in Singapore as of 2026.

What Should Singapore Businesses Look for in a Payment Gateway?

Four criteria determine fit for most Singapore SMBs:

1. Local payment method coverage — PayNow, GrabPay, ShopeePay, Atome, and ShopBack PayLater are non-negotiable for retail-facing businesses.

2. Fee structure — Monthly fees become significant overhead for lower-volume merchants. Per-transaction-only models are preferable for SMBs under SGD 50,000/month.

3. Payout speed — Cash flow timing is critical. Next business day settlement in SGD reduces the working capital gap.

4. MAS licensing — Any gateway processing SGD payments in Singapore must hold a valid licence under the Payment Services Act. This is not optional — it is a legal requirement.

Card transaction rates vary by gateway and volume tier — see hitpayapp.com/pricing for HitPay’s current SGD rates.

Which Gateway Wins on Local Payment Methods for Singapore?

HitPay supports 50+ payment methods in Singapore. Beyond cards and PayNow, this includes GrabPay, ShopeePay, Atome (0% interest BNPL), and ShopBack PayLater. Cross-border acceptance covers 10+ inbound wallets — a meaningful advantage for merchants in tourist-heavy areas like Bugis or Tanjong Pagar who serve Malaysian, Thai, Indonesian, Indian, and Chinese visitors.

For context on why cross-border wallet acceptance matters commercially, the alternative payment methods in Southeast Asia overview explains the wallet fragmentation across the region and why a single integration beats managing multiple providers.

Stripe covers PayNow and GrabPay but does not natively support ShopeePay or local BNPL options like Atome or ShopBack PayLater in Singapore. Airwallex’s Explore plan is free but focuses primarily on global treasury and FX — local consumer wallet depth is limited compared to HitPay.

How Do HitPay, Stripe, Airwallex, Adyen, and 2C2P Differ for SMBs?

HitPay
Built for Singapore SMBs — retail, F&B, e-commerce, and service businesses. No monthly fees, no setup fees, free sign-up with approval in 1–3 business days. Domestic SGD transactions settle next business day; cross-border payments settle T+2. Supports payment links, POS, invoicing, recurring billing, and e-commerce plugins within one platform. MAS licence PS20200643.
Best for: Singapore SMBs that need PayNow, GrabPay, ShopeePay, BNPL, and cross-border wallets — all with zero monthly fees and next business day payouts.

Stripe
Developer-first infrastructure with strong documentation and global coverage. No monthly fees. Supports PayNow and GrabPay in Singapore. Processed US$1.9 trillion in payments volume in 2025 globally. Payout timing follows a standard schedule rather than a guaranteed next-day cadence for SGD.
Best for: Developer teams building custom payment flows or globally distributed platforms that need 135+ currencies and code-first flexibility.

Airwallex
Positioned as a financial platform covering payments, FX, multi-currency accounts, and corporate cards. The Explore plan is free; the Grow plan costs USD 79/month. Airwallex provides useful context on how enterprise gateway selection differs from SMB selection. Best suited to businesses with significant cross-border treasury needs.
Best for: Businesses managing multi-currency payables, global team spend, and FX conversions — not primarily local Singapore consumer payments.

Adyen
Enterprise-grade platform processing €1.4 trillion annually. No setup fee, but pricing requires a processing volume baseline that most SMBs won’t reach. Excellent for large retailers and platforms.
Best for: Enterprise and mid-market retailers with high transaction volumes and dedicated technical teams.

2C2P
Regional specialist with over 600,000 over-the-counter payment locations across Asia. Payout speed is T+1 to T+3. Pricing is quote-based — not publicly listed.
Best for: Businesses needing over-the-counter or cash-based payment acceptance across Southeast Asia alongside card and wallet methods.

For merchants evaluating whether a full POS system is also needed, the credit card payment guide for Southeast Asian small businesses covers terminal options, card acceptance costs, and when a software-only POS is sufficient.

What Is the Practical Takeaway for Singapore SMBs?

For most Singapore SMBs — cafés in Tiong Bahru, online boutiques serving Orchard Road shoppers, service businesses invoicing B2B clients — the decision comes down to three factors: local payment method coverage, fee structure, and settlement speed.

HitPay is the only gateway in this comparison that combines zero monthly fees, PayNow, GrabPay, ShopeePay, Atome, ShopBack PayLater, 10+ cross-border wallets, and next business day SGD payouts in a single platform. Stripe suits developer-led teams. Airwallex suits treasury-heavy operators. Adyen and 2C2P suit enterprise scale.

For Singapore SMBs that want maximum local coverage without a monthly commitment, HitPay is the default starting point.

Frequently Asked Questions

How do I integrate a payment gateway with my Singapore ecommerce store?

Most major payment gateways offer pre-built plugins for platforms like Shopify, WooCommerce, and Wix. HitPay provides native plugins for all major ecommerce platforms, allowing Singapore businesses to activate payment processing without custom development. For businesses using custom-built storefronts, HitPay also offers a developer API.

Can I use an international payment gateway like Stripe or Adyen for my Singapore business?

Yes, international gateways like Stripe and Adyen operate in Singapore and support local payment methods to varying degrees. However, international providers may route settlements through overseas infrastructure, which can affect settlement timing and banking costs. Locally-headquartered providers like HitPay are often better positioned to offer faster SGD settlements and more responsive local support. For a more in-depth comparison, see Top Payment Gateway Providers in Singapore.

What is the difference between a payment gateway and a payment processor in Singapore?

A payment gateway is the interface that captures and encrypts payment data at the point of sale (online or in-person). A payment processor is the backend service that communicates with card networks and banks to authorise the transaction. In practice, many providers — including HitPay — offer both functions within a single integrated platform, so the distinction is less relevant for most business owners than the end-to-end capability of the solution.

Is HitPay a licensed payment gateway in Singapore?

HitPay operates under MAS licensing in Singapore, which means it complies with the Payment Services Act framework. This is an important consideration for Singapore businesses that require their payment processing infrastructure to sit within a locally regulated environment.

Does HitPay support PayNow for Singapore businesses?

Yes. HitPay supports PayNow and PayNow Corporate natively, along with PayLah!, GrabPay, Atome, major credit and debit cards, and other local payment methods — over 50 payment methods in total. PayNow support is included without requiring additional integrations or custom development work.

Which payment gateway in Singapore has no monthly fee?

Several Singapore payment gateways charge no monthly fee, including HitPay, Stripe, and PayPal. HitPay charges no monthly subscription and publishes flat transaction rates publicly at hitpayapp.com/sg/pricing, which makes it straightforward for SMEs to forecast payment processing costs. Always compare total cost of ownership, not just the absence of a monthly fee.

What is a payment gateway in Singapore?

A payment gateway in Singapore is a licensed technology service that processes payment transactions for businesses. It connects the buyer's payment method — whether that is a credit card, PayNow, PayLah!, or e-wallet — with the seller's bank account, handling authorisation, fraud screening, and settlement. In Singapore, payment gateway providers must comply with the MAS Payment Services Act.
