President Small-Business (50 or fewer emp.) 5/11/2023 "Horrible Customer Service" 0.5/5 What do you like best about NMI Gateway? There's nothing new about the gateway that I've noticed; however, I don't generally board any merchants to your gateway any longer. The only thing that is kind of convenient is the fact that we can go in, sign in as the merchant, and set up is pretty easy, but the majority of other gateways that we resell do the exact same thing. Review collected by and hosted on G2.com. What do you dislike about NMI Gateway? Once you guys acquired Iris, your service went extremely downhill, and it's continuing to drop. The service levels continue to not get any better at all. You can send an email and get a response back days, if not weeks, later. US AEPAY is even worse yet. I don't really have too much good to say about NMI other than it's an easy setup. Review collected by and hosted on G2.com. What problems is NMI Gateway solving and how is that benefiting you? A reliable gateway that customers are happy with that is easy to navigate. Review collected by and hosted on G2.com.

CA Charles A. Project and Business Development Director Financial Services Small-Business (50 or fewer emp.) 12/19/2025 "Proactive Support and Seamless Integrations" 5/5 What do you like best about NMI Gateway? I like that with NMI Gateway, as the Processor, I can log in and assist my merchants, which is crucial for those who are not tech-savvy. This proactive support capability sets NMI apart from other gateways like Authorize.net. The login function is really helpful as it allows me to see exactly what the merchants are looking at or to get the details they are missing. Another big feature I find incredibly useful is the ability to have multiple processing backends loaded up on NMI. This lets me easily swap or point to another backend without needing a whole new gateway, especially if one goes down. The uptime has been phenomenal, and it's been a great experience using them for about 6 years with very few issues. It's my top recommended gateway, a 10 for me. Review collected by and hosted on G2.com. What do you dislike about NMI Gateway? I wish that NMI could pull in deposit details. That's the main thing they are missing. If they had that feature, it would be the best gateway out there. Review collected by and hosted on G2.com. What problems is NMI Gateway solving and how is that benefiting you? NMI Gateway lets me login and help non-tech savvy merchants directly, enabling proactive support.

I love the Virtual Terminal in NMI Gateway that allows merchants to key in transactions, issue refunds, run batch reports, and manage customer billing profiles.
