“Can a Utah ISO reseller carve out a durable merchant acquiring niche by competing on rate guarantees and hardware bundles, or does the rebrand signal a strategic pivot?”
National Processing LLC is a Utah-based independent sales organization (ISO) and credit card processing reseller — distinct from the large Kentucky-based NPC (National Processing Company, owned by Vantiv). It offered merchant acquiring services including in-person, online, and mobile payments, along with check processing and hardware. In 2025 the company rebranded to PaymentBox, signaling either a repositioning or wind-down of the original brand.
