Company Overview

About NMI

NMI (Network Merchants Inc.) is a payment technology company founded in 2001 and headquartered in Schaumburg, Illinois. The company operates a white-label payment enablement platform that allows independent sales organizations (ISOs), independent software vendors (ISVs), payment facilitators, and financial institutions to offer their own branded payment acceptance products without building the underlying payment infrastructure from scratch. NMI''s platform handles the full payment stack: gateway routing, omnichannel payment processing (online, in-store, in-app, and unattended/kiosk environments), merchant management, tokenization, fraud prevention, and reporting — all delivered under the partner''s own brand.

Business Model & Competitive Advantage

NMI was acquired by Actis Capital, a growth markets private equity firm, in 2019. The company processes over $200 billion in annual payment volume across a global network of partner ISOs and ISVs, and serves customers in over 40 countries. Its platform supports a wide range of payment methods and hardware, allowing software companies and payment distributors to build vertically specialized payment products (for restaurants, healthcare, retail, field service, and other verticals) on top of NMI''s gateway and processing infrastructure without requiring direct card network or bank relationships at the infrastructure level.

Competitive Landscape 2025–2026

NMI competes with payment gateway and enablement platforms including Stripe (for software platforms), Payrix, and Priority Commerce, as well as acquiring bank gateway products. Its differentiation lies in the depth of its white-label model — ISOs and ISVs can fully brand the merchant portal, statements, and support experience — and its support for complex omnichannel deployments including unattended payment environments (parking, vending, self-service kiosks) that require specialized hardware certification and terminal management capabilities. The company''s scale ($200B+ volume), longevity (24+ years), and private equity backing under Actis position it as a stable enterprise infrastructure partner for payment distributors.
