Why I'm Qualified to Write About Credit Card Processing and Merchant Account Services

I'm a former credit card processing sales director who left the industry because I didn't like how it takes advantage of small business owners. It feeds like a leech on businesses and thrives by imposing fees that are nearly impossible to comprehend. Seeing a need for change, I left and built this website help business owners better understand the industry, research merchant services providers, and get refunds of excessive merchant account fees. My experience of working "behind the curtain" in the industry, and using that knowledge for good, has resulted in millions of dollars returned to hard-working small business owners as well as enterprise-level companies.

From the time that I starting working in the merchant services industry to when I left to create this website, I've been on the pulse of payments for nearly 15 years. It didn't seem fair to keep this "insider" knowledge to myself. To lift the fog, I've reviewed hundreds of companies, read thousands of user reviews, and learned the pricing tricks of every provider. If you have questions about credit card processing, you can find the answers on this website.
