Overall, I would strongly recommend ANY subscription based business to try it out. We started off with a one user and then gradually added more users and it was a great experience. SubscriptionFlow Team is EXCELLENT and they really spend the time with you to get you familiar with the system. In our case they have set everything for us for free, even data importing and migration of all customer payment information from Authorize.net. We had some customization required which they did for us. I think they really want their product to work!
