Hello there, @judyu. I'm here to lend a hand. 

There are reasons why recurring transactions stop working in QuickBooks Online (QBO). To ensure it'll create, let's make sure that the template is set to Scheduled and has not reached its End Date.

In your case, to get this resolved, let's delete and recreate the template. Here's how:

1. Click the Gear Icon at the top.
2. Choose Recurring Transactions.
3. Locate the template that stops from working.
4. In the Action column, click Edit.
5. Take note of the recurring invoice details. You'll need it when recreating the template.
6. Return to the list of Recurring Templates window.
7. Click New.
8. Enter the invoice details.
9. Click Save and Close.

Once done, let's delete the old recurring template by following the steps below:

1. On the recurring templates list, locate the template.
2. In the Action column, select the Edit drop-down.
3. Select Delete.

If you have any additional questions, I'm just a post away. Have a lovely day!
