Plex Online is an Extended ERP System, which means it handles everything a traditional ERP package handles (Parts, Orders, Shipping, etc.), plus many additional functions required by a manufacturing company such as Quality, Engineering, Tooling, Traceability, and so on. Most of our customers install a full Plex Online enterprise solution. However, those customers who need to stay with their existing ERP system, use various Plex Online modules to augment their legacy system's gaps and weaknesses.
