Record a payment, credit or write-off

• “Record a payment” on the invoice, or from Get paid. A partial payment leaves it Partially paid.
• “Credit some of it” issues a credit.
• “Apply a held deposit” uses money you are holding for that customer.
• “Write it off” when it will not be paid; “Void this invoice” when it should never have existed.
• “Reverse this payment” corrects a payment recorded by mistake.

Money owed shows everything outstanding and what is overdue; the Aging report groups it by how late it is.
