      Frequently Asked Questions (FAQ)

      What makes Nationwide Payment Systems different from big-box processors?

      We provide 24/7 dedicated relationship managers, industry-specific POS systems (retail, restaurant, B2B, high-risk), and scalable enterprise solutions — not a one-size-fits-all flat-rate model. 

      What industries do we specialize in?

      We deal with Low Risk to High-Risk Businesses of all types and sizes.  From single-location retail and restaurants to multi-location chains, high-volume e-commerce, B2B wholesalers and high-risk merchants — we cover them all and tailor the solution. 

      How do NPSONE and Smart Invoicing work together?

      The NPSONE gateway handles payments (card + ACH + payment links), and our Smart Invoicing automates AR/recurring billing — together they streamline your cash-flow and reduce manual work, with our 2-way Sync to QuickBooks Online. 

      What pricing models do you offer and how can I save on fees?

      We offer interchange-plus pricing, dual-pricing, cash-discount (0 % option) and ACH. Our goal is transparent fees and cost-offset strategies—not hidden mark-ups.

      How do you support multi-location and enterprise-level businesses?

      We provide POS infrastructure, centralized reporting, developer-APIs, integrations (QuickBooks sync etc.), and relationship-managers experienced with large roll-outs. 

      Are there a long-term contract or hidden fees involved?

      We believe in transparent agreements — no surprise hidden fees. Contract terms vary by solution; we’ll review them with you during onboarding. 

      How do you ensure security and protect against chargebacks/fraud?

      Our platform is PCI-compliant, supports tokenization, has in-house risk-department and charge-back rescue programs. We support high-risk merchants with compliance tools too. 

      How can I get started and what’s the typical timeline?

      Book a demo/call with us. For most retail/restaurant clients requiring a terminal, we can have you approved in ~2-3 hours once docs are complete; for higher-risk clients it’s typically 2-3 business days.  

      Do you offer Point of Sale Software and Hardware or SaaS software?

      Yes, we offer Retail, Restaurant, Bar, and other point of sale and SaaS products you can look at our offerings and book a demo.
