SellTreez: Why is the “Total Cost” in the Inventory Log Report not matching the “Total Cost” listed in the Invoice Report?

Question:

Why is the “Total Cost” in the Inventory Log Report not matching the “Total Cost” listed in the Invoice Report?

Answer: 

If there is a discrepancy between the “Total Cost” of the Invoice Report and the “Total Cost” of the Inventory Log Report (when filtered by Invoice Received date), it could be due to the fact that the Inventory Log Report stores the point in time cost of the invoice while the Invoice Report will reflect an updated invoice cost when the cost of an item is changed, even if the cost change happened outside of the filtered date of the invoice report.

For example, Product X’s “Total Cost” is showing as $0.50 on the Inventory Log Report but the Invoice Report is showing $0.05. Both reports run for the same time period 1/1/23 - 1/31/23. Investigation reveals that the package was received in January with total cost of $0.50 but the cost was then edited on 2/1/23 to reflect total cost of $0.05.

Even though the reports were run for the month of January and the change was made in February, the Invoice Report shows the updated cost while the Inventory Log Report remains unchanged from its point in time “Total Cost” when it was initially received.
