Apple will charge a 27% commission for app purchases made using alternative payment systems in the Netherlands, as part of its compliance with a legal decision. This commission is lower than the typical 30% commission charged by Apple's In-App Purchase system. Developers will have to send a report to Apple each month listing their sales, and Apple will send out invoices for its commission. The move is seen as a response to regulatory pressure to open up the App Store to alternative payment systems.
