Fine. But to go to 7 users people would be demoralized to pay 299$. Seems some error in configuring your tiers.... please have a relook.

Limits are pretty soft for number of users on various tiers. For more than 5 years been using a very well established product which sells single lifetime user licenses for much humbler prices. Honest and fair feedback for you to re-eval your limits, since this might actually make you a viable and attractive deal for many more people.
