Our company has been using (dare I say under-utilizing) QuickBooks Enterprise Desktop for many years.  We believe that we could achieve significant improvements in our job costing and inventory management by developing and deploying build assemblies for the various products we fabricate or assemble and eventually install.

We are wondering what the best practices might be to undertake a project like this to be able to thoughtfully develop the various inputs to the application.  Is it feasible to work with a set of files for a "mock company" without disrupting the ongoing business files?

We'd like to develop the process and details and test them before adding the elements to the company's actual live files and operations.  Is that difficult to do?
