When integrating from another program, you'll need to speak directly to that third party software. QuickBooks works with many different applications. But, when we are bringing information over from another software, that software's customer support will have more knowledge on how it integrates with QuickBooks Online and what information can be carried over and what can not.
I recommend reaching out to the RS support team to have them explain more on the integration process with QuickBooks Online.
