Case Study: Stax achieves 100-300% monthly new-merchant growth and <24-hour onboarding with NMI

Fattmerchant - Customer Case Study

Stax, a payments provider serving a large and growing portfolio of merchants and ISVs, needed a trusted integration partner to streamline onboarding and unify online and in‑store commerce. They partnered with NMI and adopted NMI’s modular omnichannel commerce platform—with prebuilt shopping cart integrations and EMV‑certified hardware—to simplify their technology stack and support many different merchant configurations.

NMI delivered a straightforward integration in about a week that gave Stax greater control over configurations and faster onboarding. The results included 100–300% monthly increases in new merchants, 0% attrition on the NMI gateway over 12 months, and onboarding times cut from 72 business hours to under 24—improving merchant satisfaction, reducing support time, and expanding options for their ISV partners.
