Plex is an ERP system developed for an auto parts manufacturer and expanded to address issues in several industry verticals. Purchased in June 2012, Plex is owned by Francisco Partners, a private equity group specializing in high tech business. Plex’s main office is in Troy Michigan and has about 300 employees with about 850 clients; each client may have multiple installs.

Plex Systems powers over 1,100 plants in 20 countries with a 95% renewal rate. Plex provides its entire ERP solution via an online service, meaning users need nothing but a log-in and a web browser to get started. Unlike retrofitted solutions that claim to be in the cloud, Plex provides a single technology stack to all of its customers, meaning lower costs, higher scalability, and access to continuous innovation.


  • Plex is best suited to repetitive discrete manufacturing for Make-to-Order (typical in Auto) and Make-to-Stock for companies of $25M+ in revenues and multiple plants.
  • Plex is focused on Motor Vehicles, Aerospace and Defense.
  • Plex was designed from the ground-up to connect suppliers, manage materials, control machines and deliver the accounting, human resources and business intelligence.
  • Includes fully integrated EDI as well as key trading partner mappings.
  • Complete machine integration means Plex connects people and machines and tools on the plant floor.
