How to Create a Custom Report

Is it possible to create your own custom reports in WordPress or more specifically in Storefront? I need to create a link that will take a customer to say a report showing total sales, with a separate line fore each order they collected, without giving them access to a WordPress Dashboard. There are so many plugins that advertise “custom reports” but they all have prefabricated reports that contain way to much and must be accessed from the dashboard. All I am trying to do is give a customer a link that will enable them to see a simple report (spreadsheet like) that will show them their total sales.
