Pulling data from two Zoho Books modules

Pulling data from two Zoho Books modules

Hi, I am trying to figure out how to pull data from the Invoices and Expenses modules from Zoho Books to make a Income vs Expense table.  I have tried multiple versions of joining tables, but there is no column in the two modules that is named the same.  I think the logic here would be to join the tables on the date, but the date columns are named differently.

Any ideas on how to do this?
