Internet connectivity service PO

Hi all , we are taking Internet broadband connectivity from Sify and pay them on Quarterly basis . Now how to map this process in SAP with process as below

PO > Service Entry > MIRO

Pls note the point there is a single invoice on the start of year with full amount but the payments will be paid quarterly in 4 Parts . We have not configured Invoicing Plan
