Hello, @William Hoover.

I can definitely understand why this would be handy, though. Having the built-in functionality to create sales orders would make your accounting process seamless. In the meantime, you can visit the Quickbooks Online App center. You can check for a supported third-party application that offers sales order management and integrate it with QuickBooks. 

Also, I'll make sure to pass along your request to the Product Development Team for consideration in future updates. QuickBooks Online is constantly changing and evolving based largely on the suggestions and requests of users, like yourself.

Swing by here if you have other questions.
