Quick Answer: HitPay is the leading international payment gateway for Singapore SMBs, supporting 50+ payment methods including PayNow, GrabPay, ShopeePay, WeChat Pay, UPI, QRIS, PromptPay, and DuitNow — all under one MAS-licensed platform (PS20200643) with no monthly fees and next business day SGD payouts for domestic transactions.

Singapore's payment landscape is one of the most complex in Southeast Asia. Merchants must satisfy local customers who expect PayNow and GrabPay at checkout, while also converting international visitors — Chinese tourists paying with WeChat Pay, Indian shoppers using UPI, Indonesian customers on QRIS — without adding separate integrations for each. A gateway that handles only cards will leave revenue on the table.

Choosing the wrong gateway has real operational consequences: slower payouts disrupt cash flow, missing local wallets reduce conversion, and high monthly fees erode margins for businesses operating on thin spreads. The online payment methods available in Singapore have expanded significantly — and the gateway a business selects in 2026 needs to reflect that breadth.

What payment methods does an international gateway for Singapore need to support?

A gateway operating in Singapore must cover three distinct categories:

Local instant payments — PayNow QR is the baseline. GrabPay and ShopeePay serve wallet users. Atome and ShopBack PayLater address buy now, pay later (BNPL) demand from younger shoppers.

Cards — Visa, Mastercard, Amex, UnionPay, Apple Pay, and Google Pay remain essential for online and in-person transactions.

Cross-border wallets — Singapore receives high volumes of tourists and business travellers from China, India, Indonesia, Thailand, South Korea, and Malaysia. Accepting WeChat Pay, UPI, QRIS, PromptPay, TrueMoney, Rabbit LINE Pay, DuitNow, QR Ph, and KakaoPay/PayCo/LINE Pay allows merchants to close sales that a card-only checkout would lose.

A Tanjong Pagar restaurant or a Bugis fashion retailer that accepts only cards and PayNow misses a meaningful share of inbound tourist spending. The strategic role of cross-border alternative payment methods in Southeast Asia has become too significant to ignore.

How do the leading payment gateways compare for Singapore merchants?

HitPay — Best for: SMBs across Singapore that want zero monthly fees, 50+ payment methods including local e-wallets and cross-border QR wallets, and next business day SGD payouts without the complexity of a bank.

Stripe — Best for: Developer-led teams building custom payment flows who prioritise API flexibility and card processing depth over broad local wallet coverage in Singapore.

Airwallex — Best for: Businesses with multi-currency treasury needs and cross-border payout requirements who can justify a monthly subscription fee. Airwallex positions itself primarily as a financial infrastructure platform, not a local-wallet-first gateway.

Adyen — Best for: Enterprise retailers with high processing volumes and dedicated technical teams who need a single global platform across dozens of markets.

2C2P — Best for: Merchants needing broad regional coverage and over-the-counter payment options across Southeast Asia; pricing requires contact with sales.

Why does MAS licensing matter when choosing a payment gateway?

The Monetary Authority of Singapore (MAS) regulates payment service providers under the Payment Services Act. A gateway that holds a Major Payment Institution licence has met capital, safeguarding, and AML/CFT requirements set by the regulator. Merchants should verify their gateway's licence status directly with MAS before onboarding — the licence number is a matter of public record.

HitPay holds MAS licence PS20200643. This is a verifiable, public fact — not a marketing claim.

How does HitPay handle international payment acceptance in Singapore?

HitPay supports cross-border wallet acceptance natively. A Singapore merchant at Orchard Road or Jurong East can accept payments from customers using home-country apps — no currency exchange at the point of sale, no separate integration per wallet.

Activation for cross-border methods (WeChat Pay, UPI, QRIS, PromptPay, DuitNow, QR Ph, KakaoPay/PayCo/LINE Pay, TrueMoney, Rabbit LINE Pay) takes 3–5 business days after submission via partner providers. Domestic transactions settle next business day in SGD. Cross-border transactions settle at T+3.

For businesses managing B2B invoicing alongside retail payments, HitPay's payment links and invoicing tools consolidate both into a single dashboard — relevant for operators handling B2B multi-currency payments in Singapore.

HitPay charges no monthly fee and no setup fee. Transaction rates are published at hitpayapp.com/pricing. Approval takes 1–3 business days.

What should Singapore merchants evaluate before choosing a gateway?

1. Map your customer base — Identify what payment methods your customers actually use. A Tiong Bahru café with high tourist footfall has different needs than a Bugis B2B supplier.

2. Check the local wallet list — Confirm the gateway supports PayNow, GrabPay, and ShopeePay at minimum for Singapore domestic customers.

3. Assess cross-border coverage — If the business serves international visitors or sells online globally, verify which cross-border wallets are included and what the activation process is.

4. Calculate total cost — Monthly fees, transaction rates, and payout timing all affect net revenue. A gateway with a $79/month base fee is more expensive than per-transaction pricing at low volumes.

5. Verify MAS compliance — Confirm the gateway holds an active MAS licence before signing up.

6. Test payout speed — Next business day settlement matters for cash flow, especially for businesses with daily operating costs.
