How can I know that my stock is low?

You can choose to be notified when your stock is about to run out or reaches a certain amount.
To do that, please click on the circle on the top right part of the dashboard and then on "MANAGE PROFILE" to access your account settings:

Then, please click on "SETTINGS" and you will land on the following page. After, please check for the "Low Stock Alert" section:

From here, you can choose the amount limit that you prefer so once your goods stocked in the virtual warehouse reach and go below this value, you will receive a notification.
Once, done, please click on "UPDATE".
