What are the processor fees vs Card brand fees?
The main difference between processor fees and card brand fees is that the processor fees are assessed by your Merchant Service Provider. These fees can usually be negotiated and are subject to the discretion of your Merchant Service Provider. The card brand fees are fees that are assessed from Visa/MasterCard/Discover/AmEx. These fees are published bi-annually and subject to anyone who accepts credit cards.
Many Merchant Service Providers make it very difficult to differentiate between Merchant Service fees and Card Brand fees.
