Already selling to Korean customers but having payment issues?

Many international merchants struggle with Korean payment gateway approvals, local payment methods and checkout flows. KoreaCheckout helps resolve these issues and connect your business with the right Korean payment infrastructure.

KoreaCheckout acts as the bridge between international merchants and the Korean payment ecosystem, helping companies launch faster with trusted Korean payment gateways.

Which Korean Payment Gateway Should You Use?

Foreign companies operating in Korea often struggle to choose the right payment gateway.

The Korean payment ecosystem is very different from international payment systems, and each gateway has different strengths depending on your business model.

KoreaCheckout helps international businesses understand the differences between major Korean payment providers and select the best option for their platform, customers and payment flows.

Toss Payments - modern APIs and strong ecommerce support
KG Inicis - one of Korea’s largest and most widely used gateways
NHN KCP - strong enterprise and platform integrations
Payletter - commonly used for digital services and cross-border businesses

Choosing the wrong gateway can create unnecessary integration work and onboarding delays. KoreaCheckout helps businesses evaluate the options and implement the best gateway from the start.

Free Korean Payment Gateway Pre-Approval Audit

Korean payment gateways and acquiring banks perform strict compliance reviews before approving new merchants.

Applications are frequently rejected due to issues with website structure, regulatory requirements, or missing information required by Korean ecommerce and payment regulations.

To reduce the risk of rejection, KoreaCheckout provides a free pre-approval audit to help international businesses prepare for gateway onboarding.

This review helps ensure your website and business model align with the expectations of Korean payment providers before the application process begins.
