Profit & Loss Detail - Cost of Good Sold (Cost not mapped to Income)

You'll want to check the item set up, Joanneyanne.

This is to ensure that you have selected the correct income account it will be posted to. Here's how:

1. Click Customers/Sales on the left pane.
2. Select Products and Services.
3. Locate the item and click Edit.
4. Under the Income account dropdown, select the correct account.
5. Make sure to check the box Also update this account in historical transactions so it will apply to the old ones.
6. Save and close.

That's it! You can run the P&L Details report again to see if it's now added to the correct account. Check ut this article to learn how to customize reports: Common custom reports in QuickBooks Online.

I'll be here if you have additional questions.

Hi Mary, 

Thanks for your prompt reply. 

I have followed the steps and found that the account is correct. 

Please see below:- 

Inv. 11451 with sales amount $38,560.00 is now tagged to cost $67,120.00 and the same goes to Inv. 11452. What should I do to map Inv. 11451's sales amount $38,560.00 to its cost of $33,560.00 instead of $67,120.00?

Thanks for coming back here, Joanneyanne.

When you set up an inventory item, there's a section for Purchasing information. This field is where you will enter the cost you pay for the item, as well as the expense account you want the cost to track to.

To check why invoice 11451 with sales amount $38,560.00 is not mapped on the correct COGS amount $33,560.00, I'd recommend reaching out to our Customer Care Team. They can do a screen sharing session and help you map the transactions.
