Max Listed Quantity is a setting available for eBay and Amazon that allows you to control how much inventory Zentail tells these channels you have.
There are 3 main reasons sellers use Max Listed Quantity:
Your eBay selling limits would prevent you from listing more of your catalog since listing value is determined by Item Price x aggregate units of inventory across all listings.
You want to create the appearance of scarcity.
You don't want competitors to know how much inventory you actually have.
Once your Max Listed Quantity is set for eBay and/or Amazon, the quantity on the channel will always show the lesser between that limit and your actual inventory.
