We're using Stripe to handle subscriptions and payments.
Why Stripe?
Stripe is being used by Shopify, Google, Slack, and Zoom to name a few, and is one of the largest online payment processors in the world. All payments with Stripe are extremely secure and fast.
The Stripe portal is always up-to-date and gives you, as a user of RogerRoger, a great overview of your subscription and payments.
