The story
InterPayments positions itself as 'Payments Switzerland' — a Managed Surcharge Provider that layers compliant credit-card surcharging on top of any existing payment gateway, rather than replacing acquirers or processors. The company expressly does NOT monetize payment flow itself; its revenue model is fee-recovery/surcharge SaaS with a compliance indemnification guarantee across US states, Canadian provinces, and card brand rules. Growth has come via partner distribution with major gateways/processors (Worldpay/FIS, Stripe) and ERP embedding (NetSuite, SAP, Epicor).
