Great read if you are in the business of making money. Since we launched SyncPad, pricing (for enterprises) has been the most difficult thing to decide.

One thing not mentioned is that, even before pricing, is important to define what are you charging for. While in some cases it's easy (Photoshop charge per seat), in other it isn't because there are several variables in the application usage. In our case there are several thing we can charge for: users, concurrent users, concurrent rooms, and length of the meeting. Focusing your pricing on one thing instead of the other could radically change the amount of revenues as well as the perception users have about the price.
