I need a booking system that allows for tracking of bookings by Agents/Affiliates including commission tracking. Does Bookit do this?

I was looking for something like Akeeba Subscriptions which integrates with Docman.

The site is a subscription site with various different subscription levels and users can access and download documents that are accessible to that subscription. Akeeba Subscriptions manages expirations and automatically removes members from the relevent Docman groups when their subscription expires but leaves them in allowed groups (ie free access).

I need a document management system that will integrate with a subscription system. There will be multiple subscriptions with different levels of access required.

Is there a subscription extension that is compatible with Joomdoc?
