Case Study: STM Brands achieves a 20% operating margin increase with Plex Systems' DemandCaster

STM Brands Increases Operating Margin by 20% with Plex DemandCaster Supply Chain Planning

STM Brands, a global maker of premium tablet, laptop and phone accessories founded in 1998, was losing margin to rising air‑freight costs and fragmented, spreadsheet‑based planning. The company lacked accurate demand visibility, collaborative planning and cloud access, which led to expensive expedited shipments, stale inventory and disconnected decision‑making.

By deploying Plex DemandCaster integrated with NetSuite, STM gained visualized forecasts, faster scenario planning and cross‑functional collaboration to optimize inventory and shipments. The change delivered measurable gains: gross profit margin up 5%, operating margin up 20%, air‑freight usage cut by 50% and freight‑to‑sales down 25% year‑over‑year.
