There are two main reports for inventory items, both of which are available under Reports → Sales Order Reports → Listings and Exports:
Inventory Item Custom Listing and Export
Inventory Item Quantity Adjustment Listing and Export
Both of these reports use the common Custom Listing and Export engine, thereby allowing you a great deal of flexibility.
