weAudit.com is an auditing/management firm. Representing the interests of merchants. Credit card interchange is one of the most complex industries to understand. Banks and credit card processors engage in very deceptive billing practices, making it imposable for most merchants to understand it. Until now, merchants had to turn to their banks and processors in order to perform an audit on themselves to find out how they could lower their fees. The problem, of course, is that by asking those banks and processors, the merchant is essentially asking the bank to cut their very own profits!
