NMI Payment Gateway - 2026 Pricing, Features, Reviews & Alternatives

The NMI Gateway is a partner-first payments platform that gives ISOs, software companies, and financial institutions full control over their payments infrastructure. It allows partners to manage how payments are processed, branded, and delivered across multiple merchant environments without being tied to a single processor or proprietary system.

The platform supports in-store, online, in-app, mobile, and unattended payments within a single system, reducing reliance on multiple providers and simplifying operations. With more than 150 processor connections, 125+ shopping cart integrations, and support for 235,000+ payment devices, NMI Gateway provides broad compatibility across the payments ecosystem. Partners can design routing strategies, choose processors, and adapt to merchant needs without vendor lock-in. Hardware flexibility enables merchants to use countertop terminals, mobile readers, kiosks, and unattended devices while maintaining consistent software experiences.

Its omnichannel architecture unifies transaction data and reporting across every environment. This creates a single source of truth for payments, simplifying reconciliation and improving operational oversight.

The platform’s modular structure lets partners add functionality as needed, such as network tokenization, recurring billing, or fraud prevention. This approach supports scalability and adaptability without unnecessary complexity.

Integrated tools like Shopify for e-commerce and Bill Connect for syncing with accounting software such as QuickBooks and Xero help merchants connect payments to the systems they use every day. These integrations reduce manual reconciliation, improve data accuracy, and streamline financial operations.

White-label configuration allows partners to present a fully branded experience across onboarding, reporting, and support. This strengthens merchant relationships and ensures partners maintain ownership of their customer experience while leveraging NMI’s infrastructure.

Automation reduces manual effort across transaction routing, reconciliation, and device management, helping partners handle larger portfolios and higher volumes with greater efficiency.

Built-in compliance and security tools—including tokenization, fraud detection, and PCI support—protect sensitive data and simplify regulatory requirements.

The Gateway’s scalable, API-based design supports growth across new markets and transaction types. Partners can add processors, devices, or features without disruption, maintaining reliability as operations expand.

Unified reporting and analytics provide visibility into transaction performance and merchant behavior, supporting better decision-making and proactive risk management. Multiple integration options—no-code, low-code, or full-control APIs—enable flexible implementation, with SDKs and sandbox testing for faster deployment.

NMI Gateway simplifies payment management by combining flexibility, automation, and control in one platform. It helps partners reduce complexity, maintain compliance, and scale efficiently while delivering consistent, branded payment experiences across every channel.
