What Mercantile Processing, Inc. (MPI) does

Mercantile Processing, Inc. (MPI) is a privately held, locally owned payment processing company founded in 2006 and headquartered in Georgetown, Sussex County, Delaware, with a secondary office in Havre de Grace, Maryland. The company sells integrated payments, payroll, and point-of-sale (POS) infrastructure to small and mid-sized businesses (SMBs), with primary use cases in retail, restaurants, and service businesses, and secondary coverage of telemedicine, small-market grocery, and high-risk merchant verticals. Its go-to-market is sales-led and relationship-driven: direct phone outreach (1-877-508-2831), website quote requests, Calendly-scheduled POS and payroll demos, and a channel-partner program with financial institutions that refer merchant customers.

MPI's product portfolio is built around a core credit card processing stack (in-store, online, mobile, virtual terminal, EMV-compliant terminals) and extends into cloud-based payroll (direct deposit, tax handling, W-2/1099), integrated POS hardware and software with inventory and reporting, payment gateways for eCommerce and software integrations, physical and digital gift cards with loyalty tracking, and on-site ATM placement. Merchant access is supported by self-serve portals for PCI compliance, statements and deposits, and gateway login. Pricing is quote-based and transaction- or subscription-priced, with monthly billing and a stated emphasis on transparent, customized rates rather than standardized plans. Operationally, MPI differentiates on local, human-led service — 14-second average call answer time and 8-minute average issue resolution — and on a 14-day average POS implementation time, supported by a 20-year operating history in the Delaware/Mid-Atlantic SMB market.
