For managing subscription this is a killer. Lots of features, especially if you're into details!

You can setup products and include those in different subscription plans which was exactly what I was looking for. I setup the products, then I include them in different subscriptions for my clients.

The support have also been awesome, I've had video meetings with them where they onboarded me and helped me setup my first subscription products and plans. They have been very friendly regarding support questions and have shown willingness to help me get things up and running!

I you haven't checked them out and you're in need for a subscription billing service, definitely check out Rainex!
