Thanks for your interests with knowing the options available in QuickBooks Online, @sherryhagemeier.
I can share some insights about the price rules in QBO. Please know that the desktop and online versions are separate services, and they have different features available.
The price rules in QuickBooks Online functions the same way as the custom pricing in Enterprise but the UI and settings are not completely the same. There are some options available in desktop that are not in QBO.
You can check this article to get to know more about the service and how to use it: Set price rules in QuickBooks Online.
If you want to compare the feature it with the QBDT Advance pricing, see this link: Automating pricing in QuickBooks: Price Rules QBDT.
Please visit here again if you have further questions. I'll be right here to guide you with the features in the program. All the best!
