NOTE: the Roll Up Invoice To Parent feature is not standard enabled in a IBIS billing platform. Please open a Digital Skies billing support ticket if required.
When a customer has a parent customer and the Roll up invoice to Parent is set to Yes, any device that is activated on the sub-customer account will automatically move to the subscription in the parent customer account. The parent is the owner of the subscription, the sub-customer is the owner or holder of the device.
Subscription details are only visible to the parent customer. A sub-customer as owner of the device can view CDRs.
In the Customer details page the option can be selected:

The customer ID for the device is the sub-customer ID. The customer ID for the subscription is the parent customer ID.
To view all devices from sub-customers in a parent customer account, select include data from sub-customers

The invoice to the parent customer will show the charges grouped per sub-customer, when the grouping selected:

A device can be moved from one sub-customer to another sub-customer by changing the customer of the device. This is only possible if both customers are sub-customers of the same parent customer and if both have the invoice roll-up to parent enabled. Else the below error message will appear:

NOTE: changing a customer ID of an active device is immediate, but the billing change, i.c. grouping of the charges to the new sub-customer takes effect in a new (following) billing period.
If a device and subscription should be linked to the sub-customer and not to the parent customer, this can be achieved by changing the owner of the subscription. This means that for this device and subscription an invoice will generated to the sub-customer, even when roll-up invoice to parent is selected for the customer.
