Hi there, @llcfinance.

Let me share insights on how the recurring transactions for reminders works in QuickBooks Online (QBO). 

Once your create a reminder, you'll have to manually reopen it and use it create a transaction. Here's how:

1. Click the Gear icon and select Recurring transactions.
2. Look for the reminder you've created, then click the ACTION drop-down list. 
3. Choose Use and review the transaction. 
4. When everything looks good, click Save and close.
