I have had customers ask about being able to do this. However, once I explain that my contract is with the company and the company would be held responsible for any actions of the employee, they change their mind. Like cbinder, we also have agreements that list which accounts the customer has set up for the service and that all accounts would be held to the T&C's.
Generally, the company wants to offer this for their employees to deposit their paychecks. I sell them on ACH origination for Direct Deposit instead. Always another way to skin that cat.
