Inventory Summary vs Group Inventory and services

I am trying to get a download of inventory ready for our Year End. I have categorized and noticed there are discrepancies in value.

Through Reports

1) Inventory and services summary approx. $450.00/Inventory icon same

2) Inventory and services list-$451,000

3) Grouped lists by category-$290,000 (still working on categorizing so some say "uncategorized"

Which list is best to download to give to employees to use without it being handwritten? I will be off on holidays when they count so I want to make sure I provide correct list.
