About The Author

Phillip Parker

CPO Creator & Founder

Since 2009, I have researched over 1,000 merchant services providers and published hundreds of payment education-related articles. This work has received national recognition, and my expertise in payments is regularly sought by large media outlets such as CNN, MSN, and INC Magazine, among dozens of others.

Shortly after graduating from college, I was recruited into a sales role with a credit card processor. Only later did I realize that the so-called "training" centered on selling expensive processing agreements... layered with hidden fees and long-term contracts. In my earliest transactions, I unknowingly steered friends and family into costly arrangements after they trusted my recommendation. When I fully understood the structure of what I had been selling, I resigned immediately and committed myself to exposing those practices. That commitment became the foundation of this website.
