This is a good visual description of how credit card processing works. It shows where we, as Merchant Account Providers fit in, and where the fees and rates common in the industry come from.
Not all merchant account providers are created equal though, as you will find. We focus on eliminating as many of the costs to merchants as possible, and in most cases, can cut large margins off credit card processing bills from other account providers.
