Thanks for checking in to the QuickBooks Community, @AnneB,

Checking your post, looks like you can use the pricing rules feature in QuickBooks Online. This is currently running in beta testing for QBO users and should be available for everyone once the test is complete.

If you want to test this preference, we have a test drive that you can use temporarily. There you can assess the Price Rules feature and see if it works for your business. To use out test drive, click the following link: QBO Test Drive

Here's how to enable price rules, follow the steps below:

1. Tap Settings ⚙ and pick Account and Settings or Company Settings.
2. Proceed to the Sales tab, then click the Products and services section.
3. Click the slider beside Turn on price rules Beta checkmark. Once enabled, it should change to color green.
   
4. Once all set, press Save and then Done.

To get started with setting up rules or find instructions on how to use it including FAQ's, see this article: Set price rules in QuickBooks Online

If you have additional questions about this preference, please tap me anytime. I'll be more than glad to help you with any features in QuickBooks. Have a nice day!
