Welcome back to the Community, @J_S_R.

Yes, QuickBooks Desktop has the option to add the Ship Via, Ship Date, and Tracking Number fields on the invoice. I can walk you through on how to accomplish this goal.

You can customize the invoice template and add the said fields above. This way, it will show up on your invoices and you can email them to your customers. Know that the Tracking Number field isn't available. However, you can enter this under the Other box.

Here's how to customize the template:

1. Click on Lists at the top.
2. Select on Templates.
3. Choose your invoice template and click it.
4. Hit on Additional Customization.
5. Under the Header section, put a check-mark for Ship Date, Ship Via, and enter Tracking Number on the Other box. Make sure that the Screen and Print boxes are all checked.
6. Press on OK when you're done.

I've attached a screenshot for your visual guide on the step number 5: 

From there, you'll be able to enter the details of these fields upon creating the invoice and have them sent to your customers afterward.
