Happy to see you here, @ThomasjrDPS.

To have a program that routinely generates and sends invoices to our clients is a huge time-saver. I'll share some insights about recurring transactions in QuickBooks Online.

Yes! The recurring transaction is the best alternative to automatically sending scheduled invoices. All we have to do is, set the start date for when it will start and the end date for when it will end.

You can set up repeating templates for items for bills, costs, and other recurring activities you regularly do. We can learn the steps in this article: Create recurring transactions in QuickBooks Online.

I'm also adding this page if you need to change the template: Edit a recurring template. 

If you still have a follow-up concern about this topic, please add them again in this thread. I'll be right here to help you out. Have a wonderful day.
