This is my scenario.
I work for Company-A and have developed and released an app in Apple AppStore. My company is enrolled in iOS Developer Enterprise Program. This allows me to host the app in our corporate appstore so that QA spread across the globe can download and test it.
Now, CustomerCompany-1 and CustomerCompany-2 are 2 of my customers who want some specialized functionality in the app that is applicable only to their companies. While I can develop the custom apps, I'm not sure how I can deliver apps to these customers so that they can host them in their corporate app stores.
Do they are also need to be part of iOS Developer Enterprise Program? Should I make separate builds for them in order to achieve this?
I will accept "NOT POSSIBLE" as an answer but need some insights to support the answer.
EDIT:
Have a look at this question and the comment by Amar is very interesting to me. IF the customers give me their enterprise certificate, can I build the app using that certificate so that they can host on their own app store. This would perfectly work for me, since I will be using customers certificate and hence we need not have physical control over the server.
