For those customers who do not have a backend system for managing assets, CG4 offers the Professional Edition, which is a stand alone asset tracking system. The Professional edition includes all the same great functionality included in the Enterprise edition but the Professional edition also allows for adding, editing, and deleting the supporting table values for locations, models, users, cost center, custom dropdowns, etc. Those customers integrating with a backend system edit those values in the backend system, not in CG4.
