Saas billing

Hey everyone!

I'm getting ready to launch my saas and one of the missing pieces is the billing.

My research has given me a list of stripe, 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 another indie hacker.

grateful for some suggestions,
have an awesome day!
