When a customer has agreed to the terms of an order for one or more of your products, you can create an invoice to record the upcoming sale.
You can delete an invoice only when it is active. Closed invoices are read-only and cannot be deleted. Open the invoice and view the Status field if you are not sure about the status of your selection.
Lock or unlock the price for an order or invoice
Close an invoice as paid or canceled
