End to End Bill Reconciliation with Telesoft Consulting Ltd. Vienna,

Introduction The InvoiceControl is a tool for reconciliation of all services invoiced to post-paid customers. It compares the customers invoiced revenue to the revenue billed and revenue captured at various network checkpoints. InvoiceControl runs either in a batch mode which allows automatic reconciliation of a huge amount of subscribers or on-demand in order to verify a particular charging scenario. InvoiceControl is a scalable solution, which is capable to handle an unlimited amount of customers for a short time period.

Introduction InvoiceControl manages customer hierarchies, tariffs, rates and discounts. It allows import, selection and synchronization of the customer and usage data in order to perform the rating, billing and discounting functionality. InvoiceControl has a built-in rating and billing agent with flexible configuration possibilities which suits almost all requirements. The discounting module of InvoiceControl allows the calculation of volume discounts based on the used service or group of services, combination of origin/destination zones. It allows definition of one or more discounts with pre-defined calculation priorities.

Functionality InvoiceControl imports the customer data, tariff and product information from the invoice print file produced by the in-house billing system Price and product definitions can be specified by using the build-in InvoiceControl user interface or imported from the in-house billing system. InvoiceControl provides charging sources synchronisation interfaces which avoids missing or duplicates of records during the reconciliation procedure. After rating, billing and discounting stages InvoiceControl compares the results with the invoices produced by the billing system and creates detail reports for the differences.

Supported charging scenarios The rating agent delivered with the InvoiceControl is capable to calculate charges from EDR (Event Data Record), coming from different kind of network elements – mobile and land-line switches, TAP, SMS/MMS centres, WAP gateways, GPRS/UMTS nodes, IN platforms etc. InvoiceControl supports almost any known charging scenarios like MOC/MTC/CF charging, Friends & Family, VPN groups, VAS (Value Added Services), wholesale and retails revenue sharing models etc. The price calculation is based on the following groups of parameters: Geographical – network, distance, origin/destination, routing Service related – service id, kind of service, direction Volume related – duration, volume, number of events, pre-priced Time dependency – daily time block (peak/off-peak), weak day, holiday Customer related – tariff indicator in the customer tree, VPN (F&F) dependency, relation to assigned products and bundles.

Tariffs, Products and discounts setup InvoiceControl has an internal data representation of the tariffs, products and discounts definitions used in the in-house billing system. InvoiceControl is capable to import prices, tariffs and products from the external system or to use API (Application Programming Interfaces) to access this directly. Optionally InvoiceControl can be delivered with a WEB based GUI (Graphical User Interface) for maintaining all related data.
