How to track unpaid invoices for accounts that place orders with a purchase order?
I am trying to figure out what the process is to manage my websites accounts that pay with a check or wire transfer after the order was sent to them. When they place an order they select the bill me option and then we are supposed to send them the invoice. After the order is placed it goes to the pending status. Then I manually create an invoice by clicking the invoice button on the order and then submit it. This puts the order in the processing stage. Once the order ships it gets marked as completed. Is there a native Magento functionality to make these orders as unpaid until payment is received and then make them as paid?
