    Add a custom column with:

For quick fixes, I merge queries on a common column and then write a custom column that replaces "null" with "no" and everything else with "Yes" 

 

Merge "Clients" query and "Invoices" queries on Client-ID.

Expand any Client-ID column
CustomColumn = if [#"Client-ID"] is null then "No" else "Yes"
