This metric measures the aggregated subscribed quantity for each plan or addon for each subscription where a quantity-based pricing model is used for a specific period.
Multiple quantities are still billed using one invoice and are prorated when the subscription changes, including when you change just the quantities involved.
Measure the total quantity of each subscription. This includes the quantity available for each plan and the addon component in a subscription.
Up: Good
