2 different paid services in one App

Hi Everyone,

We want to build an app for a client and have a business Challenge. On the one hand, the app will have a component that will require and in-app-purchase. On the other side, we will have a subscription service that will be paid for outside the app. Is that something apple allows to do, or will we get in trouble when doing in-app purchase?
