What People Are Saying About Stax - old

I came to Stax on the Comparizone website’s recommendation; I am pleased with the received service and the terms and conditions – a flat monthly fee is the best option for me. I always receive immediate feedback when I have questions or need assistance.

When I called the service number I heard Stax not Payment Depot when the operator answered. I left my number so that a representative could call me back. I received a call back from Tonya Baadkar and she explained that Stax had bought out Payment Depot. I explained my situation and she explained what I needed to do and sent me an email link to where I needed to go. After filling out the paperwork, emailing it in, and receiving confirmation I seemed finished. Then I remembered the small chip reader that I needed to send back. I emailed Tonya and within a short time she responded that l need not send the reader back because I had fulfilled my contract length. Appreciated her helpfulness and caring attitude. Thank you, Tonya, Sam H.

I'm grateful to Stax for the way they have facilitated me to help my business’s workflow be more efficient. Still, the most important thing they did for me is that they have clearly explained the nuances of the workflow while working with payment processing.




Shannon McEvoy went above and beyond to assist me with a time-sensitive matter. This allowed us to ensure all of our customer payments went through accurately and on time, and the funds could be released to our bank account in a timely manner. She was also polite and understanding, and pleasant to talk to!




Irene Ky was such a pleasure to deal with and so helpful with my issue! I was charged for my machine that I returned because of a clerical error on their side. Irene helped get the issue resolved quick and easy!
