Hello sales81,
Generating invoices to show the products and services cost isn't possible. Though, you can run a Transaction journal report for you to see the cost of your invoice. Let me guide you how.
- Click Create (+).
- Click Invoice.
- Enter invoice information. Then, click Save.
- Click More at the bottom of your invoice.
- Click Transaction journal. The cost amount of your products and services is shown under the Debit column.
Please see attached screenshots below.
You can refer to this article about products and service types for more information.
Also, you can check our page about managing customers and income if you need some help articles for your future tasks.
You can always swing by if you need help with anything else.
