Utterbond Subscriptions App

I installed this app yesterday and have had so much support since. We have a tricky business model that we have been having difficulty to enable a subscription service for (we tried a few Subscription apps, asked around for help, and scoured the app store for one to suit our needs - to no avail). After asking some initial questions on the Utterbond online support, Paresh invited us to Slack for instant messaging and has been so helpful. He has even handled the back-end of our online store to straighten out issues that we could not solve. We have made personal requests to the software to suit our needs - they have added and removed some features for us instantly, and given us an estimate of a few days to add some new features. I couldn't recommend this app enough. Thank you for all your help
