The inventory module presents differently depending on who is using it. On the jobsite or clients see the detail view, which is in fact an abbreviated version. It shows the very basics required to conduct business. The fields are locked and cannot be edited.
The management module of the inventory section is available to the owner and designated employees. This is where the prices are set, the stock levels and the additional charges are set for things like core charges and environmental levies.
The Pro version of NinjaBrew allows more users, but more importantly you have the option to giving your clients access to their quotes and the inventory detail modules. This gives them the ability to look at various products as well as play the balance between their desires and their budget.
