How do I remove a customer credit?

We do not have a unique way to handle refunds or clear overpayments outside of applying the payment to the outstanding balance of the customer. This is a feature that has been requested on our user feedback forum. If you would like to see this added to WorkingPoint, please vote for the idea:

In the meantime, the only way I have seen an overpayment be removed is by reducing the original payment amount by editing the payment that generated the credit or by applying it to an invoice.
