Most credit card processors, even the largest, are actually resellers and / or large sales offices that depend on several off-site third parties to handle the critical components involved with processing your transactions and handling your money.
By design, this can be problematic. Depending on off-site third parties means your customers’ sensitive credit card data is in several locations which can cause a greater complexity, such as a voice mail maze when you need customer assistance.
Integrity Payment Systems is The Direct Settlement Institution and handles all aspects of credit card processing under one roof by their own employees. When a company like Integrity has control over the entire process, they have control over how they can serve you and service your account.
