Invoice Status

An Invoice can be in one of four possible states:

• draft: An Invoice in draft status has no invoice number. It is only described by its ID and its SERIES. It has not been sent to the customer and, probably, its editing would not have been finished.
• opened: An opened Invoice is a real invoice with its own number and waiting for being paid.
• closed: A closed invoice is that one that has been fully paid.
• overdue: An overdue invoice is that opened one that has not been fully paid and whose due date has been expired.
