How can I Find out how my Customer usually pays me?

Hi Experts,

I need to find out How my Customer Usually Pays me? that is what is his mode of payment for the invoices billed to him.

I need to generate a report for this. kindly help.

for eg:

I have created 5 Invoices in the system and taken Payments also then the report should show me what are the payment means for all that 5 invoices.

Let me know how I can create this report. either by simple query or Qpld or Crystal report ?

thanks,

Amit.
