cancelling an invoice marked as paid

[root2rise1]

I sent an invoice to a customer who chose to pay in person with a swiped transaction.  When I tried to link the transaction to the invoice, it was marked as paid with cash.  My sales now show that I have 2 transactions from the same person for the same amount on the same day.  I need to be able to cancel or change the invoice that was marked as paid, but see no way to do this without issuing a refund. I don't want to refund anything because there isn't anything to refund.  Is there anyway around this?

Hey there Root2rise1,

Not sure if this link will help but, take a look.   Note: Assuming if the invoice has already been marked as paid, you can’t cancel or delete it from your payment history, the only work around would be to issue a refund.  I'm thinking as the customer paid in cash, issuing a refund may work because it is not recorded as credit card refund.  There won't be any actual exchange in funds as compared to a credit card refund.  Just a thought....
