Inter-System Reconciliation (ISR) (formerly known as Ascertain Reference Data Audit (RDA)) is Ascertain’s subscription assurance solution. It has been created specifically to address the difficulties in achieving and maintaining good data integrity which is fundamental to billing accuracy, operational efficiency and customer satisfaction.
ISR enables an operator to assess the integrity of data within and between business critical systems. Any system containing reference data can be compared with any other relevant system.
The business case for reference data reconciliation is compelling. Financial benefits delivered by ISR include:
ISR’s key features are:
Data exceptions can be assigned a forecast and actual financial value which allows the user to measure and track the impact of issues that have been identified.

ISR data exception and mismatch reports identify missing entries in key systems which can lead to revenue leakage and under-utilisation of network assets.
ISR dashboard provides a visual summarisation to the users of all aspects of the system including operational management, error identification and issue management.
