Seal Subscriptions App

I like that this app gives the option of not auto-charging the customer, but sending an invoice instead. This avoids the customer wanting to make changes after the charge has processed. The customer service is 5-star. The app developer (Henry) is very responsive to questions. He listens to the users' issues and does his best to address them. Features are added to the app all the time. For example, the app needed a necessary feature...the ability to automatically recalculate the renewal dates after a customer has paused and then restarted his subscription. I contacted Henry about it and after a while he was able to add that feature. He is always helpful!
