Most of the ERPs and off-the shelf transaction processing systems have all the required capabilities for conventional products/ services pricing and billing. These capabilities, however, are grossly inadequate to handle the usage based pricing and billing models, the new service offerings require. ARTHA Ops™ Services is a B2B enterprise application with standardized interfaces to SAP ECC that address usage based billing requirements.
