Thanks for chiming in on this thread, ciromangione.

I'd like to share some information about your concern. 

The Max field is used to track your reorder points for each inventory item. Setting up the maximum quantity allows QuickBooks to compute and suggest reorder quantities on the Stock Status report. 

You can read this article for more information about the reorder point: Set up Advanced Inventory.

Please let me know if you have any follow-up questions about the advance inventory or other concerns. I'll be around to provide details and steps to help you out. Take care and stay safe.
