I’m here to share some information with you, @accountantbynight.

When creating an item, QuickBooks Online will automatically set a zero amount if you leave the Sales price/rate and Cost section blank. Only the Products and Services List page will display blank.

You can remove the figure manually when recording a transaction associated with this item. This way, it shows blank on the Transaction page. Please see the screenshot below:

Don’t hold back to drop a comment below if you have any other questions or concerns about products and services. I’ll be here. Have a good day and always take care!

Wanting the sales price for Customer Benefit - 90 Days to be blank like Implementation Services/Program Modifications.

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.
