# invoices.void

Void an invoice nobody has paid yet (owner or office), with a reason. Pay links stop working and an open card checkout is expired. Refused when any money was collected, a card charge is pending or a bank payment is clearing: refund instead. A void invoice cannot be reopened; create a new one if needed. Change orders and maintenance terms on it can be billed again.
