Hmm...interesting. Yea, I've been fumbling a bit with the pricing structure. I thought a subscription model would be easiest for users to understand, and would give them some assurance that they're not opening themselves up to large costs that could come from per-a-minute billing.
The idea is that you use the free trial to show The Approver of Funds this works, then convert to whatever tier you think you need. Upgrade and downgrade as needed based on how many minutes you need.
I'm new to using Stripe with subscriptions and was following the basic framework from a tutorial. I plan to revisit how I do subscriptions, but I'm not sure what that will look like yet. Thought?
It was important to me to make this an MVP and ship it and then iterate on it.
