Condition in the rulebuiler which determines the (non-balanced) change of payment method.

Something like: Used payment method was > Incoice > is now > prepayment

For example, in the flow builder you could influence the mails that are sent when the status changes, so that a distinction is made between manual switching (by the admin) or automated switching (by payment integrations) and the payment method change by the customer in the frontend.

Since the order also reaches the status “canceled” when the customer changes the payment method in the frontend, these mails could be prevented here, as they can be confusing.
