Happy Monday, @krtyler.

I'm here with some insight to provide on your question regarding invoice customization in QuickBooks Self-Employed (QBSE). The instructions detailed in the original post are specifically for QuickBooks Online users. At this time, QBSE does not offer the feature to import invoice templates.

I can see how adding a personal touch to those sales forms could help your business exemplify its style, so I'm sending a feature request up to the development team for consideration. They're constantly looking to self-employed entrepreneurs like yourself when deciding how best to improve QuickBooks.

Please let me know if there's anything else I can do to be of assistance. Thanks for coming to the Community, wishing you a wonderful rest of your day.
