I understand the inconvenience you are experiencing when adding the shipping date and tracking number to your invoices, @Sailah. 

QuickBooks Online (QBO) is always striving to improve our products and software features to provide you with the best experience possible. Please know that the Ship via, Shipping Date, and Tracking No. fields still need to be prepared for the new invoice layout experience.

Checking the QuickBooks Online feature request website, you can keep track of your feature requests.

I appreciate your patience as our product development team is doing their best and fastest way to make this feature available sooner.
