Add a recurring charge
A recurring charge is a regular charge that is not based on usage, for example, an insurance surcharge or an additional charge for an increased level of support.
The recurring charges that apply to a subscription are typically defined in its plan. However, if you need to add a recurring charge that is not defined in a plan, you can add the charge directly to the subscription.
A recurring standard charge is a charge defined elsewhere that can be added to other subscriptions, for example, a charge for a fixed IP address
This task explains how to add a recurring charge.
