While listing, you can set a reminder date for any of your items with a memo. You can then be notified about those reminders on the date you set. For example, if I have an item expiring 12/1/19, and I set a reminder while I list for 10/1/19 with the memo expires in 60 days, sell or destroy then on 10/1/19 I will be notified by InventoryLab under the notifications tool which is located at the top of the screen next to settings.
If you do not put a Reminder date, but put an expiration date, a reminder will automatically be set for you for 60 days prior to your expiration date in order to allow time for you to have your items removed from Amazon and avoid fees. You can view this reminders by clicking on the small envelope at the top right of the InventoryLab page, to the left of your name.
