Thanks for posting your question here in the Community. I'm happy to provide some info about the old invoice layout in QuickBooks Online.
Good news! There's an option to switch back to the old version of the invoice layout. 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.
