THANK YOU!! That worked! 

The one final step I would like to take to fully close the loop on this is regarding the $600 refund for Customer B. I was able to add this to the Bank Deposit in the "Add funds to this deposit" section. The only issue is that this refund doesn't show up anywhere in Customer B's account history. I only see the original invoice and payment. Should I create a Credit Memo and link it to the refund I created in the Bank Deposit? Or is there some other method to demonstrate that we refunded this customer?

Thanks!!
