Thanks for joining this conversation, Matt1950.

I can add some insights about customizing sales form templates in QuickBooks Online.

You're right. Once you customize an invoice, the changes you've made will apply to the other invoice templates. Right now, we don't have an option to create a unique style for different divisions with a different name.

As a workaround, you can import your own invoice style for each division and customers. Please follow the detailed steps provided by my colleague @Angelyn_T.

I'll share this article too for reference: Sales Form Customization.
