Overview

The Tenant Billing system uses a number of different components to support the billing of Tenants. In Sigma, these components are known as “Items”. These items ultimately link a Tenant with the appropriate stream of data for recharging with the appropriate Tariff which defines how the charges should be calculated. The hierarchy and relationship between these items is shown in the diagram below:
