NMI and Stripe solve payments in fundamentally different ways. NMI is a white-label gateway: resold through ISOs and platforms, paired with a separate processor, with processor flexibility and a brandable interface. Stripe is an all-in-one payment facilitator: gateway, processing, and merchant account bundled under one flat-rate brand with fast self-serve onboarding. NMI is built for the reseller channel; Stripe is built for direct, developer-friendly signup.

Which to pick
Pick NMI if…
You're an ISO/ISV/PayFac wanting to brand payments and set pricing, or a higher-volume merchant who benefits from interchange-plus and processor choice.
Pick Stripe if…
You want the fastest self-serve setup, a flat predictable rate, and a developer-first all-in-one platform — and you're not reselling payments.
People also ask
What is the difference between NMI and Stripe?
NMI is a white-label gateway paired with a separate processor and resold under partner brands; Stripe is an all-in-one PayFac that bundles everything under its own flat-rate brand. NMI gives processor flexibility and a reseller model; Stripe gives speed and simplicity. See the white-label model.
Is NMI cheaper than Stripe?
It can be at volume. Stripe's flat ~2.9% + 30¢ is simple but often pricier at higher volume than NMI on interchange-plus through a reseller — though NMI adds a gateway fee. The total depends on volume and reseller pricing; see NMI pricing.
Should an ISO use NMI or Stripe?
NMI. It's built for the reseller channel — ISOs and platforms brand it, set merchant pricing, and choose processors. Stripe is primarily direct-to-merchant without the same white-label reseller model.
Stripe sells payments to you; NMI lets you sell payments to others. That's the real NMI-vs-Stripe decision.
