Currently if the merchant has disallowed credit cards the end user doesn't realize its their choice and not quickbooks.

How its not legally required to inform end users of their payment and the commission a service like quick book takes is crazy to me. Just be honest in business.

It is kind of shocking how many people don't realize or understand how credit card fees impact the cost of goods. If they did there might be pressure from credit card consumers to demand lower rates. If i'm paying through quickbooks, but just sending a check would save the actual business doing work a significant amount of money i'd just send them a check depending on the difference.
