So we'll need to get them checked daily and cancel them manually, otherwise we will be paying for them for the duration that they are active.

I wish there's a way that it could be like the change they did on subaccounts, where when an account's billing was removed or went past due, it pauses the subscription so they won't be able to use it. It's not cool that we pay for something linked to stripe billing where when it fails, the agency will be billed instead of the service being suspended.
