Hi there, lteruya1.
Thanks for brining your concern forward here in the Community. I'm happy to provide some info regarding the old invoice layout in QuickBooks Online.
Good news! You can actually switch back to the old version of invoices. Here are the steps to get it done:
1. In the left navigational menu, click the +New button.
2. Choose Invoice.
3. On the top-right corner, click the Old layout button.
4. Tap the Switch layout button.
5. Enter or select the necessary details, and then the click Leave and submit button.
The following linked article provides additional info about customizing invoices, estimates, and sales receipts in QuickBooks Online.
I recommend submitting feedback to the Product Development Team to let them know about the Price Rules feature and that you'd like to continue using it. This can be done directly through your QuickBooks Online account by clicking the Gear icon, then select Feedback.
Please feel free to drop a comment below if you have any other questions or concerns. I'll be here to lend a hand.
