Insights From Our Clients

What Our Clients Are Saying

A pair of blue quotation marks on a white background.

Michelle and her team did not “Sell” us a product or service. Rather, she educated us on parts of the payment business that we had no idea about and, in the process, offered us better solutions than we had at a more competitive price. She has followed up in the years since to ensure that we always have questions answered and that we are optimizing our options while minimizing costs.

Michelle has taken care of our credit card processing for over 10 years. I can’t say enough about her commitment to customer service. She goes above and beyond to make sure we are taken care of and is always presenting new ideas to improve our online business needs. We love that she is so hands on and takes care of our needs.

I have worked with Michelle Carr since 2012 and she has always offered top of the line customer service. Even when on vacation, she has found time to return my calls and help me out of a jam. She knows her stuff. I recently switched over to the Cash Discounting program, which has nearly eliminated my credit card processing fees. This lower cost solution has generated dollars that I can now invest back in to my business.
