Let other contibutors edit subscription and billing details?

I have the following problem.

My developement buddy and I set up an app and tested some features. To invite our writer we switched to basic plan. Now we wanted to invite another person to the team, who would be responsible for billing and finances. But it seems, that only the person, who changed the subscription plan in the first place, can edit the subscription and billing information.

Is there a way to transfer this permission?

Otherwise we would have to cancel the subscription to the free plan, and another one has to reactivate the subscription? But to do that we would have to kick all but two contributors? Or do I miss something?

Thanks in advance,

Right now the plans need a customer in the billing system and customer=Person. Therefore you have to cancel your subscription first. If you do this you still keep your contributors.
