I find Stripes fees excessive too, but I don’t think I’ll ever switch. I’ve been running a small SaaS product on the side of other work for >15 years and if it taught me one thing, it’s that I need to reduce the things I have to maintain, reduce manual work, reduce the things that can go wrong. There’s nothing worse than having to fix a bug in a codebase you haven’t touched for a year and possibly in a feature you haven’t touched in many years. I simply love that Stripe handles not just the payment, but the payment application, the subscription billing, the price settings, the exports for bookkeeping. I’ve had a few instances where my site was used fraudulently to check stolen credit cards and it was quickly flagged and I could resolve it with Stripe. I’m sure someone can mention alternatives and I’m sure that I could build something that would work myself, but they keep a big part of what it takes to run the business out of my mind and I’m willing to pay for that.

Fair point, though a lot has changed from 15 years ago. A lot of what you mentioned is sort of the new baseline most payment gateways ship with, and working on code you haven't touched in a while is certainly a lot easier nowadays with agents too. All that said, if you're satisfied with the price and the product I am not here to convince you to swap.
