Great Product! The team has given us the demo and show us all the important features that you might require for managing subscriptions. I really like the automated billing workflow tools which could help to streamline business processes. It also enables to manage all the activities against the subscribers within the system including emails, notes and follow up tasks etc. I have seen the other systems as well but the features SubscriptionFlow offers are by far better. I was blown away with the flexibility of the system especially it helps you to create any custom objects and link up with their system objects that itself is a unique feature.
