There is no way to let the SKU or ITEM NAME appear in the "Cost of Goods Sold Report" in QuickBooks Online (QBO), if any user wants to review the variation in cost or for any other purpose. It just lets you to display Memo/Description which doesn't fulfill the need/requirement of user. So there should be an option through which a user can tick mark SKU or ITEM NAME so that it can be downloaded in the report.

Whereas, in "Sales by Product/Service Report" in QuickBooks Online (QBO), it just shows the Sales Price but not the Cost Price so this report can't be use as an alternative for the criteria mentioned above.
