Difficult to answer based on the lack of information supplied. It all depends what sort of business you are in? Are you processing Check21 for out of state? for payroll? for over-seas US checks? On behalf of an aggregator processor? etc.
Your best bet as a start up is to talk to your bank and see if they can facilitate in your Check21 processing needs. The bank will let you know if they can or cannot process for you, based on the nature of your business.
