You are still charged ClearNow’s service fee because ClearNow is still charged a fee for attempting the debit even if it fails. If you or your tenant know beforehand that the debit will not be successful, we suggest that you do a one-time block. That way, ClearNow does not attempt the debit, and you are not charged our service fee. The tenant will need to make arrangements to pay you directly, and the autodebits will continue for the next payment period.
