How can I show what my cost for a item I sell is vs what im selling to the customer for without having it show on invoice

Hi there, ed-schellens,

Right now, we're unable to add the cost of an item to the invoice. QuickBooks will only show the sales price which is in the Rate field.

In case you want to hide the rate so your customer won't see it in their end, here's how:

1. Click the Gear icon at the right top.
2. Select Custom Form Styles under Your Company.
3. Choose the invoice template, then click Edit under Action.
   
4. Go to Content, then select Table.
5. Uncheck Rate. 
   
6. Click Done.

You can also refer to this article, Customize your invoices, estimates, and sales receipts in QuickBooks Online to learn more about the process above. It includes a quick video tutorial and detailed steps to help personalize your sales forms.

Let me know if you need additional information, and I'm always around to help you out.

Hello, GADivten. 

Thank you for reaching out to the Community. A way to track the Cost of Goods (COGS) is to make sure that there are income and expense details in your inventory items. 

Also, you can manually track the value of your inventory assets in QuickBooks Online. To start, you can create an account to track your inventory value. Here's how:
 

1. Select the Gear icon, then Chart of accounts.
2. Click New.
3. Select Current assets from the Account Type drop-down.
4. Select Other current assets from the Detail Type drop-down.
5. Hit Save and Close.

Second Create an account to track your cost of goods sold.
 

1. Select the Gear icon at the top, then Chart of Accounts.
2. Click New.
3. Select Cost of Goods Sold from the Account Type drop-down.
4. Select the closest type of Cost of Goods Sold that matches your situation from the Detail Type drop-down.
5. Hit Save and Close. 

You can refer to this article for further details: Manually track inventory. 

Then, you can run reports such as the P&L report, by clicking the drop-down arrow under Period to compare and checking the % of income box. As far as your reports including COGS, Gross Margin and Gross Margin %. You can customize the reports as follows.  

1. In the window, select the Filter ▼ icon.
2. Choose the Distribution Account drop-down.
3. Select the boxes of the accounts you want to see on the report. You can select more than one.
4. When you're ready to apply the filters, select Run report.
