For a regular full inventory session, Backbar assumes that you counted all items. If an item is left blank, it is assumed that the count is 0. Be sure when you end a full session that you have counted all your items so the quantity does not get set to 0. Before ending you will see a list of items that have not yet been counted so that you can double check.

When you are ending your inventory session you have the option to pull in existing listed quantities on uncounted items. This partial inventory session is when you count some, but not all, of your products. For example, some establishments do a full inventory once per month, but do partial inventory of their high volume products once per week to help them know what to order. 

To end a partial inventory session in the web app, you must flip the toggle below the closure timestamp selector on the last step.  Similarly, the mobile app asks directly how you would like to handle uncounted items on this step; set to 0 or keep existing quantities. Then when the session is closed, only the counted items will update, while keeping the existing listed quantities from your Inventory Items page on the remaining items.  To register an out of stock on a partial inventory session you must set a count to 0 in at least one storage location count. 

note:  This partial inventory feature only keeps totals on items that are fully uncounted in the session.
