Within ecomdash, you have the ability to track a product in multiple locations.
Due to this functionality, you can also tell ecomdash which warehouse an item is being shipped from and have that appear as a return address on a shipping label.
You can set this when navigating to Settings > Shipper Setup > Settings.
Company: You will choose this if you want the return address to be pulled from the Company Information section under Settings > General Settings.
Warehouse: You will choose this if you want the return address to be pulled from the Warehouse Details under Settings > Warehouse Setup.
