A Shopware backend user can block a payment method for b2b or normal users with the risk management rule B2B Account.
Value 1 is for blocking the payment for b2b user and the value 0 for normal user.

Every contact inherits the debtor payment after login. You can change it for an order. After another login the contact inherits the debtor payment again.
