Integrate NMI with SubscriptionFlow to Maximize Revenue
Scale your recurring revenue effortlessly by integrating NMI’s enterprise payment gateway with SubscriptionFlow. Together, they deliver efficient payment processing and intelligent subscription management to maximize customer lifetime value and reduce involuntary churn.
What NMI Offers
NMI operates as a premier payment gateway powering over $502 billion in transactions globally.
Processor Independence
NMI connects to 150+ processors and acquiring banks, so SubscriptionFlow merchants aren't locked into a single processing relationship - they can route transactions through whoever offers the best rates or the best uptime in their region.
Omnichannel Reach
Seamlessly capture transactions across ecommerce checkouts, mobile apps, and in-person POS environments through a single unified gateway architecture.
Multi-MID and Processor Routing
Distribute volume intelligently across multiple Merchant Identification Numbers (MIDs) to optimize transaction approval rates and mitigate risks.
Custom Developer APIs & SDKs
Build bespoke checkout experiences using highly adaptable integration frameworks designed for modern software platforms and high-growth merchants.
Connected Systems, Continuous Revenue Engine
Connecting NMI’s processing power to SubscriptionFlow’s billing logic turns two separate tools into one continuous revenue engine – from first charge to the last renewal.
Automated Recurring Billing
Every subscription cycle SubscriptionFlow generates, whether it is monthly, annual, usage-based, or hybrid, is charged automatically through NMI without manual invoicing or retyping card details.
Smarter Failed-Payment Recovery
SubscriptionFlow’s dunning management triggers retry logic through NMI using intelligent scheduling, recovering revenue that would otherwise be lost to expired cards or temporary declines.
Secure, Tokenized Transactions
Card data is tokenized at the point of capture and never stored on SubscriptionFlow’s servers, keeping recurring billing PCI-compliant while still enabling one-click renewals.
Real-Time Revenue Visibility
Payment events from NMI sync back into SubscriptionFlow’s reporting layer instantly, so churn, MRR, and failed payment dashboards reflect what’s actually happening. Gain immediate visibility into critical metrics like MRR, churn rates, and LTV.
Why Integrate NMI with SubscriptionFlow?
Pair NMI and SubscriptionFlow to scale your subscription business with enterprise-grade payment routing, seamless security, and automated revenue operations.
Flexible Pricing Models
SubscriptionFlow supports flat-rate, tiered, usage-based, and hybrid pricing, so businesses aren't forced to redesign their pricing strategy to fit rigid billing structures. As pricing evolves - a new metered add-on, a volume discount tier, a one-time setup fee - the platform absorbs the change without custom development. That flexibility matters most for SaaS and usage-driven businesses whose monetization models shift as they scale.
Full Subscription Lifecycle Control
From trial-to-paid conversion through upgrades, downgrades, pauses, and cancellations, SubscriptionFlow manages the entire customer journey in one system. Proration is calculated automatically when plans change mid-cycle, so customers are never over- or under-billed. This removes the manual adjustment workarounds many growing subscription businesses rely on.
Dunning and Involuntary Churn Management
Failed payments are one of the largest silent revenue leaks in subscription businesses, contributing a meaningful share of total subscriber loss. SubscriptionFlow's automated dunning sequences retry, notify, and recover these payments through NMI before a customer is lost for avoidable reasons like expired cards, insufficient funds, and declined transactions.
Self-Service Customer Portals
Subscribers can update payment methods, view invoices, change plans, or cancel without opening a support ticket. Every action taken in the portal, whether it's a card update or a plan swap, flows straight through to NMI for processing, keeping the finance and support teams out of routine maintenance.
Seamless Workflow, Real Results
A subscription business is only as strong as its ability to actually collect the recurring revenue it bills. Pairing NMI’s processing infrastructure with SubscriptionFlow’s billing automation closes the gap between “invoice sent” and “cash collected,” which is where most subscription revenue quietly leaks away.
- Reduces manual reconciliation between billing records and payment processor reports
- Shortens the time between a failed charge and a recovered payment
- Keeps card data out of SubscriptionFlow's infrastructure, simplifying PCI scope
- Gives finance teams a single source of truth for MRR, churn, and payment health
Robust Security and Risk Mitigation at NMI
NMI safeguards every transaction with enterprise-grade encryption, PCI-compliant tokenization, and advanced fraud prevention tools to eliminate security risks.
PCI DSS Level 1 Compliance
NMI's Customer Vault is built to PCI DSS Level 1 standards, the highest tier of card-data security certification, so subscription businesses processing recurring charges through SubscriptionFlow inherit that compliance without managing it themselves.
Tokenization and Network Tokens
Card data is tokenized at capture through NMI's Collect.js and Customer Vault, keeping raw card numbers off the subscription management platform's servers entirely. NMI's network tokenization has been shown to cut fraud rates by roughly 30% and lift approval rates by 4.6%.
iSpyFraud Rules Engine
NMI's iSpyFraud system lets merchants set custom rules around transaction value, frequency, and velocity, automatically flagging or blocking suspicious activity before a risky charge. This proves to be a useful safeguard against subscription-specific fraud like card testing.
3D Secure Authentication
For transactions that need an extra layer of verification, NMI supports 3D Secure authentication, shifting chargeback liability away from the merchant and adding a checkpoint against unauthorized card use on higher-risk recurring payments.
Support for Modern Payment Methods
NMI’s gateway doesn’t limit subscribers to entering a card number – it supports Apple Pay, Google Pay, and other digital wallets alongside traditional credit and ACH bank transfers, so subscribers can choose whatever payment method they actually prefer to use. For subscription businesses courting a younger or mobile-first customer base, offering these options at checkout can be the difference between a completed sign-up and an abandoned one.
Who This Integration Is Built For
The integration is suitable for modern development teams and enterprise operations looking to streamline data flows between disparate platforms.
SaaS Scale-Ups
Subscription and SaaS businesses processing recurring charges across multiple pricing tiers or currencies.
Tech Platforms
Platforms that need PCI-compliant payment processing without building their own gateway integration.
Finance Teams
Finance and operations teams that need real-time visibility in one place.
