Thanks for coming back to the Community, Matt1950.

Let me add some insights about customizing a template in QuickBooks Online.

We are unable to create two templates (for the same transaction type) that have different messages. After changing the details on an invoice template, it will affect to the other templates.

Alternatively, you can import your own style.

I'll take note of your suggestion, so I can pass this along to our product developers. You help us decide which features to build, and what improvements should be made to our platform.

That should get you on the right track.

Let me know if this works out for you. The Community always has your back, so please let me know if you have any questions. Have a good one.
