What platform can I use to collect STR payments outside of Airbnb?

[Katrin Hoppe]

I'm looking for a payment method or platform for a STR that is not listed on Airbnb. I can only find platforms that manage rental payments for MTR or LTR. Does anyone have a recommendation for a STR method of payment that is easy to use for the guest and can return payments easily in case of cancellations? Thank you!
