Is there a way for the viewed invoice function to only apply if the main email recipient views it, not anyone cc'd (ie: your business who can be cc'd)?

Hi Jody!

The option that you're looking for is not available. All recipients will be able to view the invoice you sent.

Feel free to check out other features or topics that you'd want to know. Simply click on Help and enter a keyword that describes them.
