Rockwell Automation's $2.2B-acquired manufacturing ERP/MES cloud; production floor to front-office integration for automotive and industrial manufacturers with real-time quality tracking.
About
Plex Systems is a cloud-based manufacturing ERP (Enterprise Resource Planning) and manufacturing execution system (MES) platform designed specifically for discrete and process manufacturers — providing production management, quality control, supply chain visibility, inventory management, and shop floor operations tracking in a single cloud platform. Founded in 1995 and headquartered in Troy, Michigan, Plex was acquired by Rockwell Automation in 2021 for $2.2 billion, becoming the software cornerstone of Rockwell's "The Connected Enterprise" smart manufacturing strategy.\n\nPlex's manufacturing cloud platform connects the production floor to the front office — tracking work orders, machine performance, quality inspections, lot traceability, and labor hours in real time. The MES capabilities provide production supervisors with live visibility into each workstation's throughput, scrap rates, and downtime, while the ERP layer handles procurement, inventory, shipping, and financial integration. The platform is used heavily in automotive supply chain manufacturing, food and beverage processing, and industrial manufacturing.\n\nIn 2025, Plex operates within Rockwell Automation (NYSE: ROK) as part of the Software and Control segment, integrating with Rockwell's industrial automation hardware (PLCs, drives, HMIs) and Factorytalk analytics platform. The manufacturing ERP market competes with SAP S/4HANA (manufacturing modules), Oracle Manufacturing Cloud, Infor CloudSuite Industrial, and specialized MES vendors. Plex's 2025 strategy emphasizes its integration with Rockwell's Logix control systems for closed-loop quality management, expanding in the food and beverage vertical, and growing its analytics capabilities for OEE (Overall Equipment Effectiveness) optimization.
Oklahoma City HCM software (NYSE: PAYC) at $1.88B 2024 revenue, 41% EBITDA margin; IWant AI command engine (2025), Beti self-service payroll for 37K+ clients competing with Paychex and UKG for mid-market HR platform.
About
Paycom Software, Inc. is an Oklahoma City, Oklahoma-based human capital management (HCM) software company — publicly traded on the New York Stock Exchange (NYSE: PAYC) as an S&P 500 component — providing a single-database HCM platform that manages payroll, talent acquisition, talent management, HR management, and time and labor for over 37,000 clients and 7 million+ employees through recurring subscription revenue of $1.88 billion in fiscal year 2024 with a 41% EBITDA margin and 90% annual client retention rate. Founded in 1998 by CEO Chad Richison (who funded the startup by selling his house and cashing out his 401k at age 27), Paycom was among the first companies to process payroll entirely online — pioneering cloud-based HR technology before SaaS was an established software delivery model. Paycom's single-database architecture (all HCM modules sharing one data layer, eliminating the file imports and reconciliation required by multi-vendor HR stacks) enables Beti®, the employee self-service payroll product where employees review and approve their own paychecks before processing — reducing payroll errors at the source rather than correcting them after the fact. In 2025, Paycom launched IWant™, a command-driven AI engine allowing users to access employee information through voice-to-text or typed natural language commands — named a Top HR Product of 2025 by HR Executive magazine.
