Work order
Work order billing status
Two older values, “No charge (subscription)” and “No charge (warranty)”, are kept on the records that carry them and are not written any more.
Appointment
Invoice
An invoice carries two statuses. Status says where the document is; Payment Status says what is owed.
New, In progress and Overdue are older values. The column still accepts them and invoices carry them, but nothing writes one any more.
