Thanks for posting here in the Community, jryoung. I'm here to provide details about 3rd party apps with Quickbooks Self Employed(QBSE).
Connecting third-party apps to QBSE is currently unavailable. It is only possible through QuickBooks Online(QBO) Simple Start, Essentials, and Plus subscription. If you want to add transactions that don't go through your bank, you can always manually add transactions in QBSE.
Moreover, you can check our app store to view the full range of available apps to see if any of these would be suitable for you.
Finally, if you need more advanced features to keep up with your bookkeeping, you can upgrade to QBO.
Let me know in the comments if you need further assistance regarding 3rd party apps with QBSE. Stay safe!
