Cartesian addresses the real-time nature of today’s complex communications environment with a sophisticated portfolio of audit and financial controls, an award-winning Business Assurance software suite, proven methodologies, and a hands-on approach to revenue assurance, cost management, and profitability to ensure that your business is operating effectively.
Business Assurance
Today’s communications environment, with its volume of inter-connected services and third party/content partner agreements, carries a much greater risk of reduced cash flow from revenue leakage, data anomalies and settlements, as well as escalating costs, than ever before. The ability to track and optimise revenues, improve customer service and satisfaction, manage risk, and reduce operational costs is even more challenging due to the complexity of network infrastructures, operating and business systems, multiple sales channels and business processes. Added to this complexity is the need to transition to newer technologies and systems to support the delivery of new services. These factors combine to dictate the need for a structured, disciplined approach to Business Assurance.
Cartesian believes that Business Assurance is not a specific technology, solution or activity, but a disciplined approach to improving the effectiveness and efficiency of your technologies, organisation and operations to achieve and maintain sustainable business growth and yield optimal performance. We take a holistic approach to the entire Quote-to-Cash value chain and the switch/cloud-to-bill process, bringing a unique combination of deep domain knowledge, technical expertise and proven business acumen together with the right people, processes and tools to assure your strategic business goals are met.
Our reputation has been built upon our success in assuring revenue integrity and cost containment for our clients. In conjunction with our parent company TMNG Global, during our twenty year history, the company has amassed an enviable track record of revenue assurance success, having worked with over 37 major operators around the globe, successfully recovering hundreds of millions of pounds on their behalf. Our core competencies include complex business and operations processes such as service assurance, business process management, revenue, cost and cash-flow management, billing, and mediation. Whether directing the integration of billing systems, transforming systems and networks, transitioning to cloud computing, or enhancing revenue management functions, we have repeatedly created lasting and sustainable value for our clients through improved operational performance, reduced expenditures, greater customer satisfaction and optimal efficiencies.
Our Business Assurance assessments combine our expert business assurance consulting services with our award-winning business assurance software suite, Ascertain® and our internationally recognized, proprietary Quality Business Controls® (QBC) methodology.
