Hi there, bach88.
I can tell why sales don't show up on the Cost of Goods Sold (COGS) account from the Profit and Loss or Balance Sheet report.
In QuickBooks Desktop, COGS is only affected when you sell inventory items on invoices or sales receipts. That being said, the product type you buy and sell should be an inventory.
You can refer to this article to learn how QuickBooks handles inventory items: Impacts of inventory tracking on balance sheet and profit & loss reports. This is for QuickBooks Online, however, the reporting data is the same when you run a report.
If you want to correct this, you can change the product type. Here's how:
- Go to Lists, and select Item List.
- Double-click the item you want to change.
- Select Type, then choose the new item type.
- Click OK.
If the system won't let you update the product type, you may need to create a new inventory item. For more details about this, you can refer to this article on managing your items: Add, edit, and delete items.
