01 · Processor Overview
NMI (Network Merchants Inc.) is one of the most widely distributed independent payment gateways in the U.S. It powers a huge share of ISO/ISV integrations and connects to virtually every major processor.
02 · Analyst Concerns (Opinion)
Support quality is the ISO's
NMI itself supports the ISO, not the merchant. Escalation quality tracks the reseller.
Legacy UI in places

In plain terms: Sold through thousands of ISOs — same gateway, wildly different pricing and support depending on the reseller.
