Hey there, @mcnulty.
Currently, QuickBooks Self-Employed does not support syncing with Joist. They require a QuickBooks Online (QBO) account to enable syncing.
You can try our trial version in QBO for 30 days. Check out https://quickbooks.intuit.com/pricing/ to choose a product that suits your business.
To get updates to our latest feature, you can visit our QuickBooks Blog.
If there's anything else I can do for you, please let me know. I'll be around to help you.
