Welcome back, @userjim-keaney.

I can see having an option to reorder line items on invoices in QuickBooks mobile app is helpful to you and your business. This way, your users don't have to use two different apps.

For now, I suggest submitting feedback directly to our product engineers. This way, they may look into this suggestion and consider adding the option in future updates. To submit feedback, you can click the Gear icon and select Feedback. Then, enter your suggestion and click Submit Feedback.

Want to view all your sales transactions in QuickBooks? You can go to the Sales menu and select All Sales.
