Commerce Recurring Metered Billing

Commerce Recurring Metered Billing adds support for tracking and billing for metered usage on Commerce Recurring-powered subscriptions.

The two primary use cases that are covered by the plugins included with this module are:

• "Counter" usage: Billing for usage over and above the allowed limit of a subscription plan (for example, extra API calls)
• "Gauge" usage: Billing for usage where the subscriber may increase or decrease their usage throughout the billing period (for example, hosting with per-hour billing)

You need programming experience to use this module, as it:

• requires implementing a custom subscription type for Commerce Recurring
• doesn't know what "usage" means in the context of your store, so you have to tell it
