Payment Integration Options

I am looking to integrate a payments system whereby my vendors will not have to provide bank accounts immediately upon signing up for vendor accounts and making a listing. My first choice was PayPal, but there are special permissions required to integrate and take a commission, so it does not appear that this is an option. Stripe requires vendors to link bank accounts immediately, and I view this as a significant barrier for entry for new vendors. I understand that vendors will eventually need to link bank accounts to withdraw funds, but are there any options that will allow vendors to make a listing and accept a booking without first linking a bank account?

Thank you!!

To my knowledge Stripe and PayPal are the only 2 platforms supported out the box. Would be great if we could add other ones too, but the system would have to be redesigned to add the payment providers in a modular fashion, not so easy I guess, but doable.
