I'll share some insights into why Price Rules aren't showing on the new Invoice experience, armcore. Let's work together so you can apply the rules to your invoices. 

QuickBooks has recently released new updates about the Invoice layout. In line with this, Price Rules is unavailable for the updated experience. In this case, I recommend switching to the Old layout. You can check out this image to complete this action. 

However, if you don't have an option, I recommend submitting a feature request directly to our Developers. Doing so allows us to improve your experience with the program. This will be shared with our Product Development Team. 

Here's how: 

1. Locate the Help option.
2. Under Profile, choose Feedback.
3. Enter your feedback suggestion.
4. Hit the Next button.

Please feel free to comment below with any additional questions or concerns you have, armcore. I'll be here to offer a helping hand and ensure you can effectively manage your products and services and add price rules to your invoices within your QuickBooks system. Take care, and don't hesitate to reach out for further assistance.
