Magento - Enabling Inventory Tracking

The Magento integration supports inventory tracking, however inventory tracking is not enabled by default with Magento, so you must enable it. Once enabled, inventory levels will automatically be adjusted in the Magento store based on levels reported by the warehouse management system.

To enable inventory tracking:
    
  1. Login to your Magento administration panel

  2. Click System > Configuration

  3. Under the Configuration > Catalog heading, click Inventory

  4. Change the option for Manage Stock to Yes. Click Save Config​
