The inventory for recent sets is automatically imported from LEGO. Older sets and minifigures need to have their inventory created manually. To create an inventory for an item, go to the item, click on the edit tab, and then click the create inventory button.
When new sets are created, the parts of a Minifigure automatically added, but these need to be assembled in the figures. You can click on the link from a set inventory to go to the Minifigure creation form which speeds up the process
