Ask HN: Recommended Merchant of Record and Affliate Setup

Hello Everyone, long time reader, second time posting a thread. *edit because realized I did one other time. I am nearing the completion of a product, and realized that usually when I am integrating payment it has been for other people who have figured out what providers they want. I am wondering what people recommend from experience. I really want to be able to have an affiliate program set up so that I can offer 45% to people who sell, and would love that ability built in so that I have less paper work to deal with However, I have been seeing a lot of horror stories around that the MoR I was planning to use (as it ticks every box) since acquisition, when I thought it would have increased in trust. Anyway, I thought this is probably the most trustworthy community to check with for a wide range of experiences and honesty.
