Customer Statment When Customer Raises Sales Order And Payed Advance

Hi All,

We have a Scenario Of Export Customer ......

When Customer places order ,he will pay the advance payment and next minute he will ask for Customer Statement ...

As We have not done any delivery for the order placed ,How can we bill without the delivery and provide him a upto date Customer Statement ..

Please suggest of how to go about .....

Thanks in Advance ..
