Hello, Benjamin09. 

Currently, pulling up a report of sales per billing country is not possible in QuickBooks Online. I know the importance of having this kind of feature. I'll make sure to tap this into our developer's team. Our product engineers will continue to make improvements to the product, and this preference might be available in the future in the best interest of our customers.  

You may want to consider visiting our QuickBooks Blog. From there, you can see the future developments and the latest news about QuickBooks and what our Product Care Team is working on.       

Please touch base with me here for all of your QuickBooks needs, I'm always happy to help. Stay safe!
