# Inventory - Custom Fields

PhreeBooks has a built in feature to expand inventory fields (attributes) to allow for further refinement of your inventory items. To help organize these expanded fields, added inventory fields are organized into categories. These categories become the tab headings when maintaining your inventory items. The mandatory inventory fields are, by default, put into the 'System' category (tab). If the inventory type is an assembly, a second tab name 'Bill of Materials' is also added. At least one category must be added before inventory fields can be entered. As many fields can be added to a category as are needed.

1. From the main menu select Inventory->Setup Inventory Fields.
2. Press the New button.

5. Select the category to place this field into. This will determine what tab heading the field will appear when inventory items are edited.
6. Enter the field type and properties. On some fields, default properties may be entered to pre-define the field when a new item is entered.
7. Press New to add the new inventory field.
