Reseller & ISO Portal
NMI Partner Login
NMI Partner Login is the reseller and ISO portal sign-in at secure.nmi.com/resellers — the workspace where channel partners view residuals, track portfolio analytics, and start merchant onboarding across their book of business. It is built for ISOs, resellers and software partners who resell NMI, not for individual businesses. For a single merchant account, use the NMI Merchant Login instead.
Sign in to the partner login to review residual statements, monitor processing volume, and onboard new merchants under your reseller relationship.
All NMI Sign-In Portals For ISOsThe NMI Partner Portal
The nmi partner portal is the reseller workspace for the channel — the ISOs, banks and software platforms that distribute NMI to their own merchants. Where a merchant sees one account, a partner sees a whole book: every merchant they have boarded, the volume each one processes, and the residuals that book generates.
That distinction matters. The reseller portal is designed around portfolio management and payouts, not around running a single store's transactions. Its screens answer partner questions — which merchants are growing, which are churning, and what next month's residual looks like.
Access is tied to your partner agreement, so the portfolio you see after the partner login reflects exactly the merchants that sit under your relationship with NMI.
Residuals
View and download residual statements, track payout history, and see the earnings from every merchant in your book.
Portfolio Analytics
Monitor processing volume, growth and attrition across the portfolio, then drill into any single merchant.
Merchant Onboarding
Start new merchant applications and track them through underwriting and processor boarding.
Residuals and Portfolio Analytics
For most resellers, residuals are the reason to sign in. The portal presents current and historical residual statements, broken down by merchant, so partners can reconcile payouts and forecast the next cycle. Because the numbers refresh as merchants transact, the reseller portal doubles as a live read on portfolio health.
Analytics sit alongside the statements: processing volume trends, merchant-level growth, and attrition flags that surface accounts worth a call. Partners running larger books use these views to decide where to focus retention and upsell effort. NMI's Merchant Central extends the same data into a fuller payments CRM for partners who want automation on top.
Merchant Onboarding
Boarding new merchants is the other core job of the partner portal. From the reseller workspace, partners start an application, submit underwriting details, and follow each merchant through risk review and processor boarding without leaving the portal. Status tracking keeps a growing pipeline visible, so nothing stalls silently.
Once a merchant is live, it appears in the portfolio and begins contributing to residuals — closing the loop between onboarding and payout inside one reseller portal.
Getting Partner Credentials
Reseller portal credentials are issued when you join the NMI partner program, not when you sign up as a merchant. To get access:
- Contact NMI's partnerships team to enroll as an ISO, reseller or software partner.
- Complete your partner agreement and program setup with your account manager.
- Receive your reseller portal login once the agreement is in place — it opens your residuals and portfolio views at secure.nmi.com/resellers.
- Add team members under your partner account as needed for onboarding and reporting roles.
A partner manages many merchants at once; a merchant manages a single account. If you only need to run one business's payments, the merchant login is the right portal.
NMI Partner Login — Frequently Asked Questions
What is the NMI partner portal?
The NMI partner portal is the reseller and ISO workspace at secure.nmi.com/resellers where channel partners view residuals, track their merchant portfolio, run analytics and start merchant onboarding. It is aimed at partners who resell NMI, not at individual merchants.
Is it the same as the merchant login?
No. The partner login is the reseller portal for ISOs and resellers, focused on residuals and portfolio management. The NMI Merchant Login is for an individual business to manage its own payments. A partner manages many merchants; a merchant manages one account.
How do I get partner login credentials?
Reseller portal credentials are provisioned when you join the NMI partner program. Contact NMI's partnerships team to enroll as an ISO or reseller; once your agreement is in place, NMI issues the login that opens your residuals and portfolio views.
What can I do after the reseller portal login?
You can review residual statements, analyze portfolio performance, onboard new merchants, monitor processing volume across your book, and manage the sub-accounts that sit under your partner relationship.
