recurring billing and invoice identifier (ex. 2 of 24)

For recurring billing, the invoice should note somewhere the payment number. For instance, if there are 24 billing periods and the system is invoicing the second period, the invoice should note something like 2 / 24 or 2 of 24, as customers may be confused when they receive multiple invoices for the same amount over a period of time.
