Developed in 1984, E2 Shop System is a job-based software program with shop floor control that involved both shop owners and users in its development. The system is totally integrated with the base shop floor control system being the core. Additional modules can be added including: Advanced Scheduling, Quality, Fully integrated Accounting, Bar Code Data Collection, Pocketview and Webview. Concurrent users can also be added for network users of E2. A Quickbooks accounting interface is available for shops wanting to stay on this package. The core shop floor control system includes all of the Estimating/Quoting, Order Entry, Shipments, Purchasing/Inventory, Job schedules, Job costing, Performance Analysis and Time Tracking modules. The system works well for metal fabricators, the electronics industry and assemble-to-order but is limited for mixed mode shops that use bills of materials of any complexity. It is Windows-based and utilizes “Point and Click” convenience to eliminate reliance on a keyboard.
