Our default minimum amount of stock in the Inventory Menu is 1 just like in the picture below. That means you won't be able to see Products with Zero stocks or even minus. You can change it directly from the Filter but you can also change the Minimum Default Amount on the Filter.
We will explain the steps to change the default for "Quantity From" in the Inventory menu. We will change it to Zero.
Step 1. Go to Setup, Click More Menu, then Select Module
Step 2. Go to Inventory Tab, Set Default Value, then Click Save
For the Default Quantity form can be filled in as you wish (we take the example Default 0).
Step 3. Go to Inventory Menu, then Click Filter
After you set it, you can check it back in the inventory menu then click filter, and the "quantity from" field will be changed to 0.
