Creating custom categories is currently unavailable, adamtb1. I can help you request this functionality from our developers while I provide an alternative you can consider to make a suitable one for your business.
In QuickBooks Self-Employed or Solo Trader, expense categories are aligned with the Schedule C tax form, automatically matching categorized transactions to the appropriate line. For now, we're researching options for dynamic categories while ensuring their tax functionality and estimated taxes are accurate.
I recognize the convenience of organizing categories specific to your property business, so I recommend submitting a suggestion to our Product Development Team. They may consider it for future enhancements based on the number of users' requests.
Here's how to do that:
- Go to the Gear icon.
- Select Feedback under the Profile column.
- Enter your proposal, then click Next.

Keep an eye on your suggestions on this website and visit our blog for recent developments.
In the meantime, consider switching to QuickBooks Online as they offer more advanced features like the Chart of Accounts, where you can manage categories. If you're interested, refer to this article for the details: Add an account to your chart of accounts in QuickBooks Online.
