mobile app stores - personal v. corporate customers

[Bernard Devlin]

I haven an idea for an app which would function in 2 different ways.

1. users pay to download the app, and the app writes no data back to a
server

2. companies would pay to provide the app free to their clients/staff, and
data would be transferred between the company and the end user (the end
user does not pay to download the app)

Is it possible to have an app in both the Apple store and the Android store
which functions in this way.

In the 2nd situation, the company would pay a fixed fee for the provision
of the app to their end users.  Somehow the Apple/Android stores are going
to want payment for this situation (which is not the "pay per deployment"
model).

I'd be grateful if anyone has any ideas about how such things work.

Bernard
