Cartesian’s focus is on the intersection of telecoms and information systems, providing a range of services implementing and supporting the complex systems at the heart of an operator's business.

Our consulting team is organised into two practices: the Revenue Assurance and Billing practice has a wealth of expertise across all areas of rating, interconnect, billing and customer management, and of course, revenue assurance. Our Networks and Technology practice focuses on the more technical projects such as provisioning and mediation. For more information see our Consulting section.

Cartesian’s product group has developed a market-leading suite of revenue assurance and data integrity tools. With these solutions, Cartesian has delivered impressive bottom line benefits for its customers and given them control over their costs and revenues. For more information see our Products section.

We have an enviable track record with major telco’s across the UK, mainland Europe and the US, and have delivered successfully in mobile, fixed line, cable and service provide sectors.

Recently, Cartesian helped to establish the UK Revenue Assurance Group, a forum created for operators to develop and promote best practice in revenue assurance; we now facilitate its seminar programme.
