NMI review
A multi-channel gateway for businesses that need processor choice and embedded payment tools.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
NMI provides white-label gateway and embedded payments infrastructure for independent sales organizations, software companies, payment facilitators, banks, and other payment providers. It supports online, in-store, mobile, self-service, and unattended acceptance, alongside merchant onboarding, transaction processing, reporting, and device management. That breadth makes it a fit for businesses building payment capabilities across channels or serving multiple merchants, rather than a narrow checkout tool for one storefront.
Processor and platform reach are central to NMI's proposition. The platform integrates with 200+ payment processors and 125+ shopping carts, including Shopify, and offers hosted payment pages, hosted checkout, REST and classic payment APIs, and SDKs for iOS, Android, Windows, and Linux. Payment options include major card networks, Apple Pay, Google Pay, ACH, and bank transfers. Tokenization and customer vault capabilities support recurring billing and subscription management, while 3-D Secure, payer authentication, webhooks, reporting, and multi-MID management extend the operational toolkit. These options can suit software providers and payment organizations that need to shape a payments experience around their own products and processor relationships.
According to NMI's pricing notes, pricing is handled through partners, account teams, and fee schedules rather than a standard public price list. That approach makes it important for buyers to discuss their channel mix, processor requirements, and expected payment flows directly with NMI or a partner before comparing costs. NMI also supports marketplace-related funds flows through its Dwolla capabilities. Buyers looking for broad embedded infrastructure, integrations, and multiple acceptance environments should consider it; a merchant needing only a simple single-channel checkout may find its extensive API, SDK, and account-management scope unnecessary.
