I agree with many suggestions, and I believe the results are very reproducible with some effort. I would offer an alternative approach to launching with working billing in place. I believe a good way to validate an idea is to launch a site quickly and see how easy it is to generate traffic. I would rather not spend time on coding that may never get used. And early usage may point to improvements and pivots where time will be better spent before attracting paid users. And it's possible to fake it with free trial periods that extend longer than promised. No one will complain about being allowed to continue using a site for free. And I believe it relieves some of the stress of having trying to support paid customers on early versions of a site.
