Hi @Steve Guo,
As of the moment, only QuickBooks Online Plus users are able to utilize the Price Rules Beta. Allow me to share additional insights and help you from there.
Thus, if you're a Simple Start or Essentials user, you'll have to upgrade your subscription to be able to use the new price rules. Let me show you how:
- Go to the Gear icon.
- Under Your Company, select Accounts and Settings.
- Select Billing & Subscription.
- From the QuickBooks category, select Upgrade.
Once completed, you can now be able to use and manage your sales with the new price rules beta.
In addition, here's an article you can read to learn more about upgrading your subscription: How do I Upgrade my QuickBooks Online Subscription?
It'll be always my pleasure to help if you have any other questions. I'll be always around ready to help.
