NMI Gateway Guide is an independent informational reference covering the NMI payment gateway, Merchant Central, USAePay, and the wider payment-processing category. We help merchants and partners find the correct sign-in URL, understand what the platform does, and avoid phishing. We are not Network Merchants, Inc.
What we do
NMI is a white-label gateway resold under thousands of different brands, which makes basic questions — "where do I log in?", "is this the real site?", "what is NMI even?" — genuinely hard to answer. We write clear, current explanations of those questions, with direct links to the official platform where a reader needs to sign in or get support.
What we are not
- We are not Network Merchants, Inc., and we are not affiliated with, sponsored by, or endorsed by them.
- We do not host a login form or collect usernames, passwords, or payment data. Every "sign in" action on this site links to the official gateway.
- We do not process payments or provide merchant accounts.
How we're funded
This site is supported by display advertising. That funding model is why our only interest in your sign-in is pointing you to the genuine, official URL — we have nothing to gain from intercepting credentials, and we deliberately make that impossible by never hosting a form.
Editorial & accuracy
We aim to keep platform details, URLs, and feature descriptions accurate and current; the "Reviewed" date on each page reflects our last check. Payment platforms change, and reseller configurations vary, so always treat your own welcome email and statement as the authority for your specific account. If you spot something out of date, tell us.
The official NMI
For the company itself, visit nmi.com. To sign in to the gateway, use nmi.com/logins or the branded URL your reseller provided.
