You've built a SaaS product. You have (or want) Korean customers. Now you need a Merchant of Record to handle payments without setting up local entities everywhere.

Paddle and Lemon Squeezy are the obvious choices — they're established, developer-friendly, and handle global tax compliance. But neither of them fully solves the Korean payment problem.

This guide compares all three platforms specifically through the lens of serving Korean customers. If Korea isn't part of your market, the standard Paddle vs Lemon Squeezy comparisons elsewhere will serve you better. This one is for developers who need Korean payments to work.

What's a Merchant of Record (MoR)?

Quick refresher: a Merchant of Record is the legal entity that sells your product to the end customer. The MoR handles payment processing, tax collection, invoicing, chargebacks, and compliance. You get paid via revenue share after the MoR deducts its fees.

The key benefit: you don't need a business entity in every country you sell to. The MoR is the seller of record; you're essentially a vendor to the MoR.

The Comparison at a Glance

Deep Dive: Where Each Platform Wins

Paddle: Best for Global-First, Korea-Secondary

Paddle is the most mature MoR platform. It handles tax compliance in 200+ countries, supports 30+ currencies, and has a robust API. If your product sells globally and Korean customers are a small fraction of revenue, Paddle is hard to beat.

Where Paddle falls short for Korea:

• Korean customers paying through Paddle are making a cross-border transaction. This means their Korean credit card issuer may charge additional foreign transaction fees (typically 1–2%), and the payment appears as a USD charge converted to KRW — not a native Korean payment.
• No KakaoPay, NaverPay, or TossPay. In a market where mobile payment adoption exceeds 90%, this is not a minor gap.
• If your Korean customer is a business that needs a Korean tax invoice, Paddle simply cannot issue one. This can be a dealbreaker for B2B SaaS.
• Korean businesses cannot sign up as Paddle sellers.

Paddle is the right choice when:

• Korea is less than 10–15% of your revenue
• Your Korean customers are tech-savvy individuals comfortable with international card payments
• You need tax compliance in many countries beyond Korea

Lemon Squeezy: Best for Indie Hackers (But Same Korea Gaps)

Lemon Squeezy built its reputation on simplicity — beautiful checkout pages, easy setup, developer-friendly API. Since the Stripe acquisition in July 2024, there's been uncertainty around its roadmap, but it remains popular among indie hackers.

Korea-specific situation is essentially identical to Paddle:

• No Korean local payment methods
• No KRW settlement
• No Korean tax invoices
• Cross-border card processing only

Post-Stripe acquisition concerns:

• Onboarding has slowed, with multiple developer reports of delayed account approvals
• Product roadmap has become less transparent
• Some developers have migrated to Paddle citing uncertainty

Lemon Squeezy is the right choice when:

• You're an indie hacker who values simplicity and beautiful defaults
• Korea is not a primary market
• You're comfortable with the Stripe acquisition uncertainty

koree.ai: Built Specifically for the Korean Market

koree.ai takes the opposite approach from Paddle and Lemon Squeezy: instead of handling global tax in 200 countries, it goes deep on one market — Korea — while still supporting global card payments for international customers.

What koree.ai does that others can't:

• Native Korean payment processing. KakaoPay, NaverPay, TossPay, and Korean cards are processed locally through Korean PG infrastructure. No cross-border fees for the customer.
• Global cards too. Visa, Mastercard, and Amex are supported alongside Korean methods — so you don't need a separate processor for international customers.
• KRW settlement. You get paid in Korean Won if you want. Or USD — your choice.
• Korean tax invoice issuance. koree.ai, as the MoR, issues Korean tax invoices on your behalf.
• Korean entity friendly. Unlike Paddle/Lemon Squeezy, Korean businesses can sign up.
• No-entity onboarding. Non-Korean developers can also sign up without a Korean business — the same MoR benefit you get from Paddle, but for Korean payments.

Where koree.ai is limited:

• Korea-focused. koree.ai is optimized for Korean customers. If the majority of your users are in the US or EU, Paddle's global tax infrastructure may be a better fit.
• Newer platform. Paddle has years of API maturity. koree.ai is building out its full SDK and API ecosystem.
• No global tax automation (yet). It handles Korean VAT and tax invoicing but not multi-country tax compliance.

koree.ai is the right choice when:

• Korean customers are 20%+ of your user base (or you want them to be)
• You want Korean users to pay with KakaoPay/NaverPay (not just international cards)
• You or your customers need Korean tax invoices
• You're a Korean developer without a business entity

The Hybrid Strategy: Why You Probably Need Two

Here's the insight most comparison articles miss: these platforms are complementary, not mutually exclusive.

If you have both global and Korean customers, the optimal setup is:

[Global customers] → Paddle or Stripe
[Korean customers]  → koree.ai

Why this works:

• Korean customers get the payment experience they expect (KakaoPay, native KRW pricing)
• Global customers get Paddle's optimized checkout and tax handling
• You maximize conversion in both markets
• Neither platform's weakness affects the other market

Implementation is simpler than it sounds:

• Detect the customer's country (IP geolocation or explicit selection)
• Route Korean customers to koree.ai checkout
• Route everyone else to Paddle/Stripe checkout
• Both platforms send webhooks to your backend to confirm payment and activate accounts

Pricing Deep Dive

Let's model the real cost difference using a practical example.

Scenario: SaaS product at ₩13,000/month (~$9.99). 100 Korean customers.

The per-transaction cost is meaningfully lower on koree.ai for Korean payments — and the customer experience gap is significant. A Korean user seeing a KakaoPay button versus a foreign credit card form is the difference between a 5-second checkout and a potential abandonment.

Decision Matrix

Bottom Line

There's no single "best" MoR — it depends on where your customers are.

Paddle and Lemon Squeezy are excellent at what they do: global payment infrastructure for SaaS companies. But "global" has a Korea-shaped hole in it. Korean consumers expect KakaoPay. Korean businesses need proper tax invoicing. And Korean developers need a platform that doesn't require them to incorporate in Delaware.

koree.ai fills that specific gap. It's not trying to replace Paddle for your European or American customers — it's the piece that makes Korean payments work the way Korean users expect them to.

If Korea matters to your business, the answer isn't "Paddle OR koree.ai." It's probably "Paddle AND koree.ai."

Ready to add Korean payments to your stack? koree.ai — accept KakaoPay, NaverPay, TossPay, and global cards. No Korean business entity required.

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.

Why Korean Payments Are Different

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.

The Options You Have Today

Let's walk through each option realistically, including the trade-offs nobody talks about.

Option 1: Stripe (Limited Korean Support)

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

Option 2: Set Up a Korean Business Entity

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

Option 3: Paddle or Merchant of Record (MoR)

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

Option 4: Payment Infrastructure APIs (The New Approach)

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.

What Korean Users Actually Expect

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.

A Practical Decision Framework

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

Getting Started

If you're exploring how to accept Korean payments for your SaaS or app, here's our recommended next steps:

1. 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.

2. Talk to your Korean users. Ask them directly what payment methods they prefer. You'll likely hear KakaoPay, Naver Pay, and specific bank cards.

3. 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.

4. Start simple. You don't need to support every Korean payment method on day one. KakaoPay + local cards cover the majority of online transactions.
