Hi there, barry10. 

We're always looking for ways we can make QBO better for all users, and thank you for sharing your idea in the Community. I can see how having a feature to automatically change an item's price under certain conditions in the program would be helpful. Rest assured that your feedback regarding price rules and level was shared with the appropriate department and team members.

As for a workaround, you can create and define each specific item prices you charge or sell to your customers. For more information, I recommend the following article on how to add products and services, track the items you sell, as well as how to edit them: Mange Products and Services List.

Thanks for dropping by. Wishing you and your business success.
