It's good to see you again, DanW1,

Thanks for providing more details.

In QuickBooks Online, there are pre-created accounts for Products and Services like Sales and Hours that cannot be changed.

The error message “You cannot change the product and service type for this item“ happens if this item you’ve been trying to change is the pre-created accounts.

To help us resolve the problem, you can create a new item for Rad Survey as a Non-Inventory type.

If you have further questions in creating Non-inventory items, please feel free to reach back out. I'd be happy to answer it for you. Have a great day!
