Try TheEcheck, they are a Check21 payment processor who offers their merchants the ability to accept eCheck payments online or over the phone through VT/API. They are in the U.S and are a very reputable company to do business with. Good Luck!
Where is your business located and what are you selling?
We are a merchant that is looking for Check processing such as Check21 or ACH but can't seem to find any reliable companies. Can somebody direct me because I haven't been able to find anything so far.
