I had a great experience with Quantum ePay, and especially with David Tran. David was extremely helpful, professional, and responsive with the set up of our new terminal. He took the time to answer all of my questions and made everything easy to understand. It’s refreshing to receive this level of customer service. David was knowledgeable, patient, and genuinely helpful from start to finish. I really appreciate his assistance and would definitely recommend David and Quantum ePay to others. Great experience overall! but

Quantum eBay has excellent staff available to support my business 24/7. They email you when they are not available to assist such as holidays. Staff need a break too! These guys are great

We had an issue with tip adjustments on a new credit card machine, and David was incredibly patient and helpful throughout the entire process. He took the time to go through every single transaction with me and even reviewed the entire batch report to catch transactions I had missed. His professionalism, attention to detail, and willingness to help made a stressful situation so much easier. Best customer service with David Tran!

I've called several times this week for assistance with my POS and Reynaldo has been very helpful! Each time he has been patient, thorough and professional. I couldn't ask for better customer service and I have a huge sense of relief after resolving my issue. THANK YOU VERY MUCH!

We recently switched from Clover to Quantum. I was nervous but within 24 hours I was so glad I made the change. The customer service exceeds any other business. These guys genuinely care and are so helpful. Martin was exceptional and explained everything in easy terms for us. Any small issue I had, Martin addresses right away. Top notch people to do business with! I highly recommend them.
