To resolve the 3.1.1 issue

I develop an application for entreprise only with external purchase mechanisms : I do not understand if it's really possible or not.
If I read the article "3.1.3(e) Goods and Services Outside of the App", it seems is it possible but my application is refused because of this???

What is really possible and what is really forbidden? I sell service like training, advice, and custom development : functionalities inside app are different according to my client.


Is it possible to get an in-app purchase for using application (basic uses) and B2B services with premium content in application with outside purchase?

thanx for your help !
