All accounts can view recent changes to inventory (under the Inventory page), but Free accounts are focused on the NOW.
Pro accounts can access Reports and Exports under the Menu for additional information.
Under the Tables section is a to/from date driven display of all orders, going as far back as you wish.
There are also multiple exporting options when you need to take your data with you.
Adjusting the dates automatically updates the list of completed orders in the system. Columns can be shown/hidden for displaying details of each order.
