Hi shawnfreeman-gma,
At this time, the option to add a user to your books, with access to submit receipts only, isn't available in QuickBooks Online. I recommend reviewing this guide about User roles and access rights in QuickBooks Online.
If you would like to see this option in future updates, please don't hesitate to submit a suggestion to our Development Team by going to your Settings ⚙, then select Feedback. Customer recommendations are greatly appreciated in assisting us with improving your overall customer experience in QuickBooks Online.
If you have any other questions, feel free to reach out. We would be glad to help!
