I have an employee that paid an invoice with a company check and his personal funds (which should not have done). How do I apply the payment to the invoice so the total of the invoice is paid in QB and pay the employee back his personal funds?

Example:

Invoice                  $590.00

Company Check   $575.00

Employee Cash    $  15.00

I apply the $575 company check but the balance on the invoice is still $15.00 in QB.

Thank you
