In house solutions. Once a company becomes large enough where paying a company like Stripe's fees becomes larger than hiring enough people to create and maintain an internal billing system, then you do it yourself.

This is something that companies that are near public company size do since the amount of work required to meet payment regulations alone, not to mention all of the infrastructure to support things like subscriptions is staggering.

This is why there aren't many solutions to this problem. It's a very difficult problem.

I have migrated 2 companies away from internal billing systems (one went to Stripe and the other went to Chargify). The amount of hacks that went into maintaining these internal systems was shocking. One company literally devised its own currency to deal with the complexity.

Managing and developing your own billing system is a almost always a bad idea, no matter how big your company is. There is a high likelihood that you will end up running a business within a business if you go that route.

Yea it depends on the technological competencies of the company. I have a friend who works at a company who implemented their own, and they seem to be doing fine, but you hit the nail on the head saying
