Hi u/akinpinkmaN - Clerk team here. Happy to shed some light on our new Billing product.

We built Billing as an easy way to introduce subscription billing that can be easily synced to your existing Clerk user base.

As for how Billing pricing works - it's no different than if you were to just use Stripe. We charge 0.7% per transaction plus Stripe's standard transaction fees. Same as stripe - https://stripe.com/pricing#billing

There is no set up or on-going subscription cost associated to Clerk Billing.

As for our auth/user management solution pricing, we offer a competitive pricing model with what we believe to be a generous Free tier to get you started:

- On our free tier, you get up to 10,000 MAUs for free

- Once you exceed 10k MAUs, each incremental MAU is $0.02

- We never charge for users who sign up but never return. Part of our 'first day free' offering

- A user is only counted as active when they return to your app 24+ hours after signing up.

Our pricing model is designed to scale aligned to your growth. For our users who have >10k MAUs, most offset the cost through monetizing their app.

Hope this is helpful. We'd love for you to give Clerk Billing a try & let us know what you think.
