Real business scenarios for using recurring invoices

Hi,

I wanted to confirm if the following business scenarios qualify for using recurring invoices or not??

Case 1:

The firm needs to pay out utility bills every month in a financial year which is fixed or increments  by a certain percentage every month. so if for example the electricity bill fluctuates every month(decreases and increases), can we use still use recurring invoices ?

Case 2:

The annual rent was paid in as advance during beginning of the financial year and it needs to be amortized as expenses every month (amortization of prepaid expenses).

Can you site more practical examples for application of recurring invoices..?
