I add non-inventory item and include purchasing info with Cost listed and COGS account. Create invoice with this item but then my P&L then shows a sale with no COGS.

Hello there, jessica42.

In QuickBooks, the Reports for Cost of Goods Sold (COGS) only show how you have set up the item. I can walk through how to verify it.

Here's how:

1. Login to your QuickBooks
2. Go to your Sales menu.
3. Then choose Products & Services.
4. On the search bar, enter the name of the product.
5. Click Edit.
6. Scroll down and verify the Income and Expense account.
7. Click done. Save and Close.

If you set up the COGS for an Expense, the COGS will not show on the P&L reports. The expense for the Cost of Goods Sold will only be shown if the item is part of the inventory. 

If there are any changes, you can review the Audit log to see who made the changes.

I will also include this article to help you identify missing income and expense transactions in your Profit and Loss report.

If you have any further concerns or questions about how to include the cost of goods sold for non-inventory items in the P&L report, feel free to leave a comment on this thread.

A non-inventory item added to an invoice will never post to COGS at that time.  A non-inventory item will expense the cost to COGS on your P&L when you purchase the item, not when you sell it.  Only inventory items post to COGS when entered on an invoice.
