Hey there, abstractjuz.

Let me welcome you first to the Online Community. Thanks for being so detailed with your concern.

I want to ensure the amount recorded for your products/services are correct. However, I need some information as to where did you see the £20.00 for the manufacturing costs?

While I wait for your response, run the Profit and Loss Report by Cash to see that the costs are not combined.

From there, go to the Cost of sales section to see the amount used by QBO when creating the expense.

To pull up the report:

1. Go to Reports on the left panel.
2. Enter Profit and Loss Report in the search field, then select the correct date.
3. Click on Run Report.

Next, go to the Product Income section and click on the amount for your invoice to check the transaction details. On the invoice, the item is calculated by item multiply to the initial cost.

This information should point you in the right direction.

If you have additional questions about QBO, please post a comment below. I’ll be right here to help.
