Simple to use and easy to understand. I have a subscription service I offer my clients, and the system makes it easy to add them as customers then setup recurring billing on their credit cards. The Batch Manager and Customer Roster are the most heavily used areas for me. The pricing is also extremely competitive, but it's the support I get that really makes it attractive. Recently I needed ACH payment capabilities integration, and Ben and the team made it super easy to do that! My customers love the payments page and the details that are e-mailed to me make it easy for me to reconcile my ledger in Quicken. The payment page loads quickly and my clients enjoy how fast the payment process is. Review collected by and hosted on G2.com.

It is difficult for me to offer a valid criticism of this system, since it does everything really well. Combined systems like Quickbooks don't offer nearly the same experience and costs a lot more. I even think the reporting options are better than Quickbooks. Review collected by and hosted on G2.com.

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.

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.

What I like best about NMI Gateway is its flexible payment infrastructure and developer-friendly integration options. The gateway provides a straightforward way to integrate payment processing into an existing platform through APIs while supporting a broad range of transaction and merchant-management capabilities. I also appreciate its compatibility with multiple processors, which provides greater flexibility when building and scaling a payment platform. Review collected by and hosted on G2.com.

One area that could be improved is making some of the more advanced gateway features and configuration options easier to understand and access. More detailed technical documentation, clearer implementation examples, and a more streamlined onboarding process for advanced API integrations would make the overall experience even better.

NMI is the most advanced feature-filled payment gateway out there. We especially like the network token functionality (Customer Token Vault) and the Shopify integration. It just works! Review collected by and hosted on G2.com.

The reporting for multiple MIDs and subreseller accounts is limited, but there's a new Insights window that seems to be a start for improving this. Review collected by and hosted on G2.com.

I like the ease of setting up merchants and the integrated e-check application in NMI Gateway. It's relatively simple to set up even though it took some time initially. I also appreciate the connections with QuickBooks and the better pricing compared to QuickBooks’ own payment processing. Review collected by and hosted on G2.com.

The reporting is difficult to locate and can be difficult to understand with the CSV files. I could use something with more insights into my payment processing. Review collected by and hosted on G2.com.

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.

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.

I like Fee Nav and am interesting in learning more about merchant central and their integration opportunities. Acquired technology stack seems to be improving for agents. I'm hopeful for the technology benefits. Review collected by and hosted on G2.com.

Sometimes support holds can be long and I'd like to see more interaction with resellers prior to wide pricing changes. Review collected by and hosted on G2.com.

At FNBO we work with a lot of gateways and we continue to prioritize NMI over all of them. It's easier to use, customizable, can use cloud based terminals, and is affordable. Review collected by and hosted on G2.com.

The ability to pass level 3 data on EMV terminal processors Review collected by and hosted on G2.com.

It allows us to connect to various other software. Review collected by and hosted on G2.com.

The pricing is a la cart and can get expensive. The UI feels dated. It is sometimes hard to figure out the different options available in the gateway. Review collected by and hosted on G2.com.

Credit card network tokenization. Great integrations as well. Review collected by and hosted on G2.com.

Would like to not see gateway price increases. Review collected by and hosted on G2.com.
