Ask HN: SaaS Billing?

Hey everyone!

As title says, looking for billing for a new saas.

My research has given me a list of stripe, Mollie, Adyen, braintree and cardinity.

multiple payment types/options is obviously a requirement, and paypal in there would be absolute plus.

Is there any other suggestion? I would love to use maybe a new up and comer, perhaps even ran by someone here on hackernews.

grateful for some suggestions, have an awesome day!
