With Microsoft NCE it is possible that you have multiple subscriptions with different renewal dates for the same end customer.  

To manage subscriptions with different renewal dates we recommended creating separate contracts.

To enable this.

- Enable NCE

- Select in the contract wizard for the end customer new contract:

- Select Microsoft NCE: Create contract for each product billing plan.

Based on the renewal date we create different contracts.

All the Monthly subscriptions are combined in one Contract.

Yearly subscriptions are combined based on the renewal Month.
