Pay Per Use Subscription Management

The service manager supports pay per use (PPU) subscriptions, since many distributors and service providers use the PPU billing model.

Please note that the following two terms are sometimes used interchangeably in the BSS and in this section:

  • Resource: a reserve supply that can be drawn upon when needed
  • Usage: is the act of using a resource

The endpoints in this section provide an overview of the consumption of a PPU subscription.

Billing Items Endpoint

Swagger Documentation: POST /api/Ppu/billingItems

The Billing Items endpoint is used to get the final charges that will be included in an invoice for a specific billing cycle of a Pay per Use subscription.

Request & Response

The request of this endpoint contains the same fields as the Usages endpoint.

The usage records obtained from GetUsages may be grouped to show fewer entries in the invoice.

The response is also similar, the main difference being the BillingCycleStatus field. This field indicates the status of the billing process, for the requested billing period in the third party system.

Whether or not to proceed with the billing process and invoice generation is decided by the value of BillingCycleStatus:

  • Open – When the collection of usages is incomplete for the specified billing period
  • Closed – When the collection of usages is complete for the specified billing period

BillingCycleStatus must be equal to Closed only when there are no more charges to include for the billing cycle. Any subsequent collection of usage data will not affect the charges provided for the billing cycle.

When this Endpoint is Called

The endpoint is called when the billing services run at the end of every day.
