Prepayment and recurring invoice

Hi,

I want to create prepayment invoice and then apply the prepayment equally over the next 12 months.

ex: create prepayment invoice in January for 120000.00 an apply the prepayment equally over the next 12 months so each month's invoice will have 10000.00 applied to it.

In other words,

Create prepayment invoice at beginning of the year.

Create recurring invoice at the beginning of the year.

Apply the prepayment to these recurring invoices for next 12 months.

 

WHAT ARE THE STEPS TO ACHIVE THE ABOVE FUNCTIONALTY.

 

Thanks in advance.
