Hi there, sjohnson3.

You can change the shipment address of your invoice in the Gear icon. Let me show you the steps on how to customize your invoice.

1. In your QuickBooks Online company.
2. Go to the Gear icon and select the Custom Form Styles.
3. Select the New style button and click Invoice.
4. In your Design tab, Customize the template name.
5. Click on the Content tab, and click on the Header part of the document.
6. In the Header section click on the +Address.
7. Enter the address, then verify the details and click Done.

I added a screen shot for your reference.

You can now create an invoice and click on the Customize tab at the bottom of the page, choose the one you've made with the right shipping address.

Count me in whenever you need further assistance. Have a good one.
