CAL's fee billing and how o confirm current contract status.

I have an enquiry from a Partner, Fuji Xerox information system regarding below. Because they are still waiting for the invoice of CAL's fee, they understand they need to pay(They understand they have not got the invoice yet).

1. What timing will the invoice should be sent to whom(Who is an Invoice recipient)? Because the invoice without the recipient is often left.

2. How they can confirm current contract status, like remaining FOC period, billable period?
