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.

In the EU and had to switch from Stripe to Mollie due to Stripe thinking the client was a cruise company because they rent 'cruiser' boats for river leisure. Mollie was super easy to implement for them, and fees much better

You can't really do better than stripe. The onboarding overhead is because of fraud and the costs are basically barely above interchange.
