Thanks.  But that doesn't work. There is no issue with quantity.  The adjustment previously made was in the form of a fake vendor credit memo, not an inventory quantity adjustment.

If I go in to edit the starting value, but date it 1/1/2021 and indicate that there are 4 quantity on hand at $X (the correct value), charge the account "inventory adjustments" instead of opening equity,  will that eliminate all the activity related to this item prior to 1/1/2021?

And I AM THE ACCOUNTANT...A CPA with 40 years of experience.  I fully understand what needs to be done...just working with the limitations of QBO.  I really hate when the final answer from support is "contact your accountant." This isn't an accounting question..it's a QBO mechanics question.

There should be way to adjust inventory values for a specific inventory item.
