We fully believe that companies have a right, if not actually a necessity, to operate as efficiently as possible, and we support the proper use of chargebacks to achieve that goal. 

However, it is our experience that too often the supplier is presumed guilty and must prove innocence, sometimes several times over, to get their incorrectly assessed chargebacks refunded.  This is the opposite of the basis for the legal system in the United States, which presumes innocence until guilt is proven.

Further, certain aspects of vendor compliance programs typically run contrary to various provisions of the Uniform Commercial Code.

If, as a company, you cannot accurately and effectively judge, monitor, uniformly assess and enforce chargebacks across all your suppliers, then you should rethink your chargeback policy. 

It can be argued that the purposeful withholding of monies due a supplier based on faulty analysis could be considered fraud. 

Further, it could be considered fraud to withhold monies above-and-beyond the actual cost to correct the compliance violation.
