POS Inventory Adjustment account

There is something wrong with your accounting procedures. Inventory adjustment is always a positive number, it represents the value of items lost, damaged, or stolen.

If the number is negative, you have to have been stocking items using inventory adjust. That process removes the value of the item from the adjustment account, driving it negative.

You need to get with someone who understands QB inventory and get help.

I am no expert but from the trend I've noticed is that all adjustments go into that account. A negative (Credit Balance) in that account most likely means that there was more inventory counted which resulted in an increase in inventory.
