A practical guide for global developers and SaaS teams

You built a SaaS product. Users in South Korea found it, loved it, and want to pay. Great news—until you realize that accepting Korean payments is nothing like accepting payments anywhere else.
Stripe doesn't fully support Korean local payment methods. Korean PG (Payment Gateway) providers require a Korean business registration number. And your users won't pay in USD when KakaoPay is two taps away.
This is the guide we wish existed when we started building koree.ai. If you're a global developer or SaaS team trying to accept Korean won from Korean customers, here's what you actually need to know.
South Korea is one of the most digitally advanced payment markets in the world. Card transactions make up over 58% of all e-commerce payments, and mobile wallets like KakaoPay (24M+ users), Naver Pay (30M+ users), and Toss Pay (25M+ users) dominate the rest.
But here's the catch: the payment infrastructure is built for Korean businesses, not foreign ones.
Most Korean PG providers—NicePay, KG Inicis, Toss Payments—require a 사업자등록번호 (Korean business registration number) to open a merchant account. If you're a foreign company without a Korean entity, you're essentially locked out of the local payment rails.
This creates a frustrating gap. Your Korean users expect to pay with their preferred local methods. You can't offer them. Revenue is left on the table.
Let's walk through each option realistically, including the trade-offs nobody talks about.
Stripe lets you accept Korean credit cards through international card networks. Recently, some Korean wallet support has been added via partner integrations like Easy.Pie.
What works:
You can accept Visa/Mastercard issued by Korean banks
Some wallet support (KakaoPay, Naver Pay) through third-party plugins
Familiar API if you already use Stripe
What doesn't:
Transactions are processed as cross-border, which means higher decline rates
Korean consumers see foreign currency charges and get suspicious
Fees are higher than local processing (typically 3.4% + 30¢ vs. local rates of 2–3%)
You're not offering a native Korean checkout experience
The most "proper" route. Register a Korean subsidiary (법인) or sole proprietorship (사업자), get a business registration number, open a Korean bank account, and sign up with a local PG.
What works:
Full access to every Korean payment method
Local processing rates
Complete regulatory compliance
What doesn't:
Minimum 2–3 months to set up
Requires a Korean director or registered agent
Ongoing accounting, tax filing, and compliance obligations
Minimum capital requirements for certain entity types
Overkill if Korea is 5% of your revenue
Paddle, Lemon Squeezy, or Gumroad act as the merchant of record, handling payments and tax compliance globally.
What works:
Zero setup for you—they handle everything
Tax compliance included
Simple integration
What doesn't:
Korean local payment methods are either unsupported or limited
Higher fees (typically 5–10% of revenue)
You lose control over the payment experience
Korean users still see a non-Korean checkout flow
A newer category of services that act as a bridge: they hold the Korean PG relationships and licenses, and expose a developer-friendly API that foreign companies can integrate.
What works:
Access to Korean local payment methods (KakaoPay, Naver Pay, Toss Pay, local cards)
No Korean business entity required
Developer-friendly API integration
Local processing = higher approval rates, lower fees
Korean-native checkout experience for your users
What doesn't:
Relatively new category—fewer providers to choose from
You're relying on a third party's PG relationships
This is the approach we're building at koree.ai—and we offer a free tier (no fees on your first ₩1M/month) so you can validate Korean demand before committing.
Before you choose an approach, understand what your Korean users experience when they pay online:
Local payment methods are non-negotiable. A Korean user expects to see KakaoPay, Naver Pay, or their local bank's card. Showing only Visa/Mastercard at checkout signals "this is a foreign service"—and for many users, that's a reason to leave.
KRW pricing matters. Showing prices in USD and letting the bank handle conversion creates friction and distrust. Dynamic currency conversion fees (typically 2–3% on top of the exchange rate) make the actual price unpredictable for the buyer.
Mobile-first checkout. Over 70% of Korean e-commerce happens on mobile. If your checkout doesn't work seamlessly on a phone—including app-to-app redirects for KakaoPay and Toss Pay—you're losing conversions.
Trust signals are different. Korean users look for different trust indicators than Western users. A Korean PG logo at checkout, Korean-language support, and KRW pricing all contribute to perceived legitimacy.
Here's how to decide which approach fits your situation:
Choose Stripe if:
Korea is less than 5% of your revenue
Your Korean users are comfortable paying with international cards
Speed matters more than conversion optimization
Choose a Korean entity if:
Korea is or will be a major market (20%+ of revenue)
You need the full range of local payment methods
You have the resources for ongoing compliance
Choose a MoR (Paddle/Lemon Squeezy) if:
You want zero payment operations overhead
You're okay with limited Korean payment method support
Tax compliance across multiple countries is your primary concern
Choose a payment infrastructure API if:
You want Korean local payment methods without a Korean entity
Developer experience matters—you want a clean API, not a legacy integration
You need KRW pricing and a Korean-native checkout
Korea is a growing market you want to invest in, but not enough to justify a local entity
If you're exploring how to accept Korean payments for your SaaS or app, here's our recommended next steps:
Audit your Korean user base. Check your analytics for South Korea traffic. If you're seeing significant Korean visitors who aren't converting, payment friction might be the reason.
Talk to your Korean users. Ask them directly what payment methods they prefer. You'll likely hear KakaoPay, Naver Pay, and specific bank cards.
Estimate the revenue opportunity. South Korea's e-commerce market generates over $150 billion annually. Even a small slice of the Korean market can be meaningful for a growing SaaS.
Start simple. You don't need to support every Korean payment method on day one. KakaoPay + local cards cover the majority of online transactions.
At koree.ai, we're building the payment infrastructure layer that lets global developers accept Korean payments through a single API—no Korean business license required.
We handle the PG relationships, regulatory compliance, and local payment method integrations. You get a clean API, KRW pricing, and a checkout experience your Korean users will trust.
You can start accepting Korean payments for free—no fees on your first ₩1,000,000 in monthly transactions. That's enough to validate Korean demand for your product without any financial risk. When you grow past that, simple transaction-based pricing kicks in.
We're currently in private beta. If you're a developer or SaaS team looking to accept Korean payments, join our waitlist for early access.
