Forum Post: RE: Is there a way to have a one-time charge that will not have interest charged against it on future invoices, although the same client is charged interest on fees and cost?

I did apply the credit for $2,000 towards interest but that is the problem. I have to reverse it out so I can go forward and charge the interest that should be charged. I do not know how to reverse out that credit when I have already invoiced that client more than one time. I know we can undo an invoice one time, but I do not know how to show they owe the $2,000 again. If I could reverse it, the program would automatically know that interest should be charged correctly but I cannot reverse it since I can only undo an invoice once. Everyone's help is appreciated.
