PaymentHub
PaymentHub + NMI: Leverage NMI's processor-agnostic gateway for maximum flexibility in processor selection while PaymentHub handles ERP posting, reconciliation, and fee optimization.
PaymentHub's NMI integration connects NMI's processor-agnostic payment gateway to your ERP's general ledger.
Supported Payment Methods
Routing Rules & Orchestration
Processor-level routing through NMI — choose the best processor for your card volume and negotiate directly
Multi-processor configuration — different processors for different card brands or transaction types via NMI
ACH routing through NMI or dedicated ACH provider based on fee comparison
Failover at the processor level — NMI can failover between processors without changing the gateway integration
Volume-based processor optimization — shift volume between processors based on rate negotiations
Fee Optimization
Level 2/3 Data Enrichment Supported
PaymentHub automatically enriches transactions through NMI with Level 2 and Level 3 line-item data, qualifying B2B card transactions for lower interchange rates. Most merchants save 30-60 basis points per transaction.
NMI's processor-agnostic model creates unique fee optimization opportunities. Because NMI connects to hundreds of processors, organizations can negotiate directly with processors and switch for better rates without changing their gateway integration or PaymentHub configuration. PaymentHub submits Level 2/3 data through NMI for interchange optimization, and the fee analysis copilot compares rates across NMI-connected processors to identify cost-saving opportunities. This combination — processor selection flexibility plus Level 2/3 data automation — delivers the most comprehensive fee optimization path available.
