Hi, As far as I know there are no support for this in Zuora, hence you need to implement it yourself outside of Zuora and utilize the APIs. By "manually" I meant implementing it in your own service/application. Found this article: https://knowledgecenter.zuora.com/Developer_Platform/API/G_SOAP_API/E1_SOAP_API_Object_Reference/Usage/Billing_Usage More specifically: "If you omit all of the fields ChargeId, ChargeNumber, SubscriptionId, and SubscriptionName, then usage is billed against all charges associated with the account that have the same UOM values. The two charge-related fields, ChargeId and ChargeNumber, connect usage with a specific charge. The two subscription-related fields, SubscriptionId and SubscriptionName, connect usage with a specific subscription." Hope this helps
