InvoicePaymentStatus

How much of the invoice is paid. pending: nothing paid yet and not past its due date. partiallyPaid: some paid. paid: paid in full. overdue: posted, not paid in full and past its due date (this wins over partiallyPaid). A posted credit invoice (a total of zero or less) owes nothing, so it's paid, never overdue. error: collecting payment failed in a way that needs your attention.
