Feedback:
Recently signed up with them and it’s been a headache since day! Started by not getting my terminal when I told I would causeing almost a week dely. Then Over the next couple weeks ran cards that were suppose to be available the next day which haven’t been. When I called them and asked a manager to call me I never got a call back from anyone. They have caused so many issues and delays in our business and aren’t owning up to it, I’m extremely disappointed with this company and their customer service
Feedback:
We switched to Quantum about a 8 months ago after much procrastination! It's always tough to make a big change in business....but our old provider was just terrible. I have only positive things to say about Rob Olson and his fabulous team. I'm glad we made the switch....you should too!
Feedback:
I've been dealing with Quantum for a few years and would definitely recommend them.
Feedback:
I was so lucky to find this company when I was searching for another company to provide POS. I was having such a hard time with my old processor. Quantum was great with me. Explaining everything that I needed to know!
Feedback:
Quantum was great at giving me great pricing! I also decided to do updating to my website. I didn't know really what I wanted, but they were patient with me, listened to my needs and created something that I am very proud of! Thank you again to the entire staff at Quantum, that worked with me.
Feedback:
Quantum is one of very few companies that you can call and speak on the phone with an actual human being within 1 minute of calling. Their staff is very knowledgeable and willing to help.
Feedback:
These guys were great! Unlike most POS companies, they didn't play games. They gave me their best rate that was better than anyone else. They were very easy to work with, and very friendly. I definitely recommend them.
Feedback:
I was fortunate enough to work with Rob in the past and have absolutely no hesitation in recommending Quantum Merchant Services to anyone!

Thank you to Rob and everyone at Quantum. You've all been so helpful responding to all our questions and helping us setup and maintain our system. We love the credit card machine as well as the chip which allows us to be mobile. Thanks again!
