What is NMI Gateway?

NMI Gateway is a purpose-built, partner-first payments platform that delivers white-label, omnichannel infrastructure across every merchant environment. Designed for ISOs, banks, fintechs, software companies and SaaS platforms, it empowers partners to offer secure, scalable, and customizable payment acceptance to their merchants. NMI does not sell directly to merchants; instead, it powers 4,000+ partners serving more than 1 million businesses worldwide.

Unlike gateways that are tied to a single processor or acquirer, NMI gives partners complete control over branding, pricing, and merchant relationships. With over 150 processor connections, 125+ shopping cart integrations, and compatibility with 235,000+ payment devices, NMI Gateway provides unmatched flexibility across retail, e-commerce, in-app, mobile, and unattended payment environments. Its flexible APIs, SDKs, and webhooks allow developers to embed and scale payments quickly, manage multi-MID configurations, and create dynamic routing strategies that optimize performance and reduce vendor lock-in.

Value-added modules extend its capabilities even further. Shopify integration supports embedded commerce experiences, while Bill Connect syncs payments with leading accounting platforms such as QuickBooks and Xero. Additional tools like network tokenization, recurring billing, and advanced fraud prevention strengthen security, reduce churn, and enhance transaction success rates. Centralized reporting and analytics give partners real-time insights into performance and transaction trends across channels.

Processing over 5.8 billion transactions annually and powering more than $440 billion in payment volume, NMI Gateway transforms payments from a back-office function into a revenue-generating growth engine. With its modular design, global scalability, and partner-first approach, NMI enables businesses to innovate faster, retain customers longer, and deliver frictionless
