Please allow my owners/clients to set up their own payment processing systems under https://app.ownerrez.com/paymentmethods
This would allow their payment processing to integrate directly into their managed listings without needing to provide me with login details to any of their payment processing accounts.
While Owners can't set up their own payment processors, it is possible for you to set up individual payment methods for each property (or group of owned properties) so the owners receive payouts directly. That can be easily configured once each owner has been approved for a payment processing account.
I understand the confidential information relating to this, and you wanting the Owners to set up their own accounts. It is likely that this will be added to a future update of the Team Access system. In the meantime, would it be possible for you to do a video call with screen sharing, so that your Owner could type the credentials in directly without having to provide them to you?
