The Inventory Valuation Report takes the total On Hand (which includes the fulfillable, unfulfillable, and reserved quantities) and multiplies it by the Average Cost Per Unit for any given day.
Click on Reports and select Inventory Valuation from the dropdown menu
The default day will be today, however, you can view your inventory values for a past date as well by clicking on the date field and selecting a past date from the calendar. Then, click View
You can also search the report by Title, MSKU, or by scanning the UPC.
This report is designed to be a snapshot in time. Meaning, it cannot be updated retroactively.
For example, if you wanted to have an accurate value provided for December 31st, you will want to have all of your Cost/Unit numbers in your Inventory by December 30th.
At the bottom graph these totals are separated by Merchant Fulfilled and Amazon Fulfilled.
It does the same thing for anything Amazon is reporting to us as Inbound Quantity (showing at the bottom as Inbound).
Then, it adds the 3 totals (Merchant Fulfilled, Amazon Fulfilled, and Inbound) together to get the Total in the bottom graph. This data is captured in a snapshot report once each day to form the Inventory Valuation Report.
