There are a few customers who have credits on their accounts with no invoices to which they can be applied. Several of these are a few years old, some of the customers are inactive, and I have no idea what the circumstances were that would've caused a payment to be recorded with no invoice. But we want to try to clean up the reports if possible. Would it be ok to just make up dummy invoices and then apply the credits? Or is there a way to clean up via journal entries?
