Ordering Subscription Products with Consumption Schedules

When you order a subscription product related to a consumption schedule, Salesforce CPQ creates an order product consumption schedule with the same field values and rates as the usage product's product consumption schedule. Access your order product consumption schedule through its related list on a subscription order product. Salesforce Billing also creates usage summaries for your order product based on the order product consumption schedule's billing term. The number and length of your usage summaries varies based on whether your order product came from a standard or evergreen subscription. (Salesforce Billing Managed Package)

• Ordering Consumption Schedules with Standard Subscriptions
  When you order a standard subscription product related to a consumption schedule, Salesforce Billing generates usage summaries based on the schedule's billing term and billing term unit. The term and term unit represent the length of one usage summary, repeated through the order product's start and end date. (Salesforce Billing Managed Package)
• Ordering Consumption Schedules with Evergreen Subscriptions
  Evergreen subscriptions are useful when you want to invoice a customer’s usage until they cancel the service. (Salesforce Billing Managed Package)
