All Indie developers or 1-3 person team need is a Merchant of Record, or simply a SaaS app store without index page like Apple Store. I don't even want to have a /billings page. Please also provide full feature customer portal (refund / cancel / pause / coupon / etc.)

And I want that store to have only literally "one" page for API documentation. All I want to check on my app is `authorized?(user.subscription)`
