I'm glad to see you dropping by in the Community, @gvernon-pacific-.
In QuickBooks Online (QBO), we can create multiple invoice templates by importing your invoice template style.
However, we can also modify the address under the Custom form styles. Make sure to update the information in the default template so that the address does not change.
Here's how:
- Go to the Gear icon.
- Under Your Company, select Custom form styles.
- Click the New style drop-down arrow, then choose Invoice.
- Select the Content tab.
- Click the Edit pencil icon under the Business name.
- Select the Address link, then enter the Street address, City, State, and Zip code.
- Hit Done.
You can check this link to import your templates: Import custom form styles for invoices.
Furthermore, I suggest checking out this article. It contains additional insights about customizing invoices with some visual screenshots: Customize invoices, estimates, and sales receipts.
Please know that I'm just a post away if you need more assistance in creating your template. I want to make sure you're taken care of. Have a wonderful day.
