The CIS Suffered Summary - could this be produced with the invoice numbers as a column? I cannot see an option for this.

Hello there, @foxjenningscullen. I'll share some insights about CIS Suffered Summary in QuickBooks Online (QBO). 

The only columns you can add to that report are date, amount transaction type, and customer name. 

Since this is still unavailable, I recommend sharing this idea with our Product Development Team. Please also know that we're unable to provide a timeline for when this will be implemented.
