Apply a Returned Check Fee to A Paid Invoice

Problem 

How do  I apply a Returned Check Fee to an already paid invoice? If the invoice is already marked as "Paid in Full" how do I edit it, to add on the extra fee?

Solution

First we need to void the transaction of the paid invoice, to "unlock it" for editing.  
- Go to the transactions tab and search for the paid invoice transaction using the date field at the top.  

-Or you can just press the green cash button on your invoice. (It does the same thing) 

- Press Void selected, and then Yes on the prompt to Void all invoices in the list. 

Next, go Back to the invoice and it will be unlocked for Editing.  
- Add in an Invoice charge for the Returned Check Fee.  

Lastly, depending on the situation, you may need to either re-apply the original check amount to the invoice (If it has yet to be paid), or apply the new full amount to the invoice (if it has been paid already). 

Re-Apply Original: -Just receive payment for the original check amount, be sure to include the same check number as before in the details. 

Paid in Full:- Pay the full balance of the invoice, including the new charge. (Banks will credit businesses in some cases, for ISF)
