Thanks for reaching out to the QuickBooks Community, @xcsorg.
QuickBooks Self-Employed (QBSE) have only one default invoice template and customizing it isn't available as of the moment. And I appreciate you for sharing this idea. Finding new ways to adapt to our customers’ needs is how QuickBooks gets even better.
I'll make sure to take note of this and will inform you once we receive product enhancement update about the availability of this feature. In the meantime, I'd suggest visiting our QuickBooks Self-Employed Blog regularly. This way you'll be updated with the latest news and updates including product improvements.
Please know that you're always welcome to post if you have any other questions about the QBSE service. I'm always here to help.
