Case Study: Therma-Tru Doors achieves 100%+ daily shipping growth and 95% fewer invoice chargebacks with Technology Group International's Enterprise 21 ERP

Enterprise 21 Offers an Automatic Doorway to Enterprise-Wide Savings for Therma-Tru Doors

Therma-Tru Doors, the nation’s leading manufacturer of fiberglass and steel exterior door systems, had outgrown its in-house software and faced fragmented data across multiple U.S. and Mexico facilities, high WIP inventory, below‑optimal manufacturing output, inefficient warehouse operations, and frequent invoice errors. To address these challenges, Therma‑Tru engaged Technology Group International to deploy its Enterprise 21 ERP software with advanced manufacturing functionality.

Technology Group International implemented Enterprise 21 across Therma‑Tru’s sites, consolidating data and adding integrated manufacturing and supply‑chain capabilities. The result was a dramatic operational turnaround: daily shipping output increased by over 100%, invoice charge‑back rates dropped by more than 95%, WIP inventory carrying levels were significantly reduced, production rose with better multi‑site reporting, and visibility and reporting improved across manufacturing and distribution centers.
