Apple says South Korean app developers can now use external payment methods from KCP, Inicis, Toss, and NICE by submitting a new version, reducing fees by 4%
Earlier this year, Apple announced that it would comply with a new law in South Korea that required the company to allow third-party payment providers in App Store apps. Source: Apple Developer .
Context & Ripple Effects
South Korea’s legislature first required Apple and Google to permit alternative in-app payments, and Apple subsequently said it would comply. The new submission path turns that policy commitment into an implementation route for named local processors.
The important constraint was already visible in Apple’s approach to third-party payments elsewhere: alternative checkout does not eliminate the platform commission. South Korean developers now receive a defined 4% fee reduction rather than a fully independent payments channel.
First-order effects
- South Korean App Store developers can submit updated apps using KCP, Inicis, Toss, or NICE payment methods, while Apple lowers its applicable fee by 4%.
- KCP, Inicis, Toss, and NICE gain access to app-based transactions that had been routed through Apple’s in-app purchase system.
Second-order effects
- Developers must weigh the 4% lower Apple fee against each processor’s charges and the operational cost of maintaining an alternative payment flow.
- Apple retains a monetization role even when payment processing moves to local providers, limiting how far the mandated choice changes the App Store’s economics.
Third-order effects
- The South Korean model points to regulated app-store opening as a negotiated take-rate change rather than a clean separation of distribution from payments.
- As more jurisdictions press platform operators on payment rules, the key competitive question becomes whether permitted alternatives leave enough margin for processors and developers to adopt them.
The trend: App-store payment regulation is shifting gatekeepers toward allowing external processors while preserving a reduced platform commission.
