A Simple Payment Gateway for Singapore Businesses

Choosing a payment gateway in Singapore should be simple. ONE Payments gives you one all-in-one platform to accept cards, PayNow and popular digital wallets online, so your customers can pay the way they prefer and you get paid faster. There is no setup fee and no monthly fee — you only pay when you get paid, which keeps things cost-effective as you grow. Whether you run an online store, a SaaS product or a growing SME, you can go live quickly with a hosted checkout, shareable payment links or a direct API integration. And because ONE Payments brings your online and in-store sales together, you can manage every transaction from a single dashboard. Explore our pricing or talk to sales to find the right fit.

Accept every way Singapore pays

Your customers expect choice at checkout, and ONE Payments delivers it. Accept major cards including Visa, Mastercard, American Express, JCB and UnionPay, plus Apple Pay and Google Pay for fast mobile checkout. For local shoppers, PayNow lets people pay in a tap straight from their banking app. Offering the right mix of payment methods reduces abandoned carts and helps you convert more sales, whether your buyers are in Singapore or paying from overseas. Every method runs through the same platform, so you do not need to juggle multiple providers or separate logins. You get one clear view of what is coming in — across cards, wallets and local rails — all in one place, which makes day-to-day reporting far easier to manage.

Go live without the setup hassle

Getting started should not mean weeks of development. With ONE Payments you can choose the integration that fits your team and timeline. Share a payment link to start collecting payments with no website at all. Drop in a hosted checkout to take payments on your site without building one from scratch. Or integrate our REST API directly for full control over the customer experience. Developers will find clear guides and examples in our documentation, so connecting ONE Payments to your stack is straightforward. However you start, you can move from sign-up to your first live payment quickly, then expand into more channels and methods whenever your business is ready for the next step.

Transparent, cost-effective pricing

Pricing should be easy to understand before you commit. With ONE Payments, domestic card payments cost 2.7% plus USD 0.50 per transaction, with no setup fee and no monthly fee. International cards add 0.7% on top, so you always know what an overseas sale will cost. There are no lock-in tiers to decode and no surprise line items — you pay per successful transaction, which keeps costs predictable as your volume changes. Higher-volume businesses can qualify for custom rates, so it is worth a conversation as you scale. You can review the full breakdown on our pricing page, or contact sales to talk through a plan that matches your monthly volume.

Online and in-store, all in one place

Many Singapore businesses sell in more than one place — a website, a storefront, or both. ONE Payments brings those channels together so you are not stitching tools together yourself. Pair your gateway with a payment terminal in Singapore to accept cards, contactless and QR payments at the counter, then see those sales next to your online orders in the same dashboard. This omni-channel setup means cleaner reporting, easier reconciliation and a smoother experience for your team. As you add new sales channels, your payments stay unified instead of fragmented. It is one platform for how your customers actually pay, online and face to face, without extra systems to maintain.
