Hi, @accountantbynight. Thank you for the screenshot, it gives me a clearer view of your concern.

The Service item will only show blank if you haven't entered any digit on its sales price when saving it the first time. The ones on the screenshot show that it has been edited, that's why it displays zero. 

I see that this will benefit other users as well. I encourage you to send a suggestion by clicking on the Gear icon and choosing Feedback.

You can also check this article with managing your products and services in your business:  Add product and service items to QuickBooks Online. This also contains some references with inventory or service reports that you can use to track your business' profits.

If you have other questions about entering data on your products and services, feel free to comment below. I'd be happy to lend a helping hand.
