Usage Data
In subscription-based business scenarios, businesses charge customers repeatedly for a continuous use of a product or service. Since this usage typically varies, they want to offer a fair, transparent billing approach – track the usage and bill the consumption.
This is what usage data billing (aka metered billing, usage-based billing or pay-per-use) does: Typically, customers subscribe to a product or service plan. It may include a (recurring) base price, but the key feature is to charge the actual consumption.
