In preparing to do an inventory count, you’ll need to consider scheduled items along with non-scheduled items. Scheduled items are still a part of your inventory at the time of performing the count and will therefore need to be included in the count.
The same holds true for scheduled items that have already been picked. These must also be included in the count as they are also still technically in your inventory. The only time when scheduled and picked items should be excluded from the count is when they have been invoiced.
