Computer Systems, a mid-sized software services company has signed an agreement with the UK-based The Carphone Warehouse (CPW), which could bring about contracts worth about $200 million by the next five years covering up a broad variety of consultancy, software and maintenance services.

The transaction grades next to similar size deals it received as ABN AMRO’s favored vendor in a $2.2 billion agreement and its actions with General electric (GE).

But, whereas the ABN AMRO agreement is in the traditionally strong area of ADM services, the CPW contract is more in a partnership nature and covers several service lines.

Neeraj Gupta, Patni’s executive vice-president and Brain Stones, European head called it a discovery, and an example of where a customer dealing has developed into an affiliation.

The Carphone Warehouse is a big mobile phone dealer with more than 2,100 stores in 11 countries. The deal’s consulting part entail redesigning a few of CPW’s business actions to facilitate them lessen costs.

The company said, “Patni will become a key technology partner providing services across consulting, systems integration, application development and maintenance. In addition, Patni will also be a key partner to The Carphone Warehouse for developing next-generation systems for its global telecom and retail operations.”

The services will be delivered from locations in Europe and from Patni centres in India. Recently, the Indian company had acquired the universal rights to CPW’s proprietary technology letting communication service suppliers in order to provide customer management, retail point of sale and billing services for a range of products and services.

Patni and CPW and Patni co-developed the technology. Services to clients in the telecommunication industry make about 14% of Patni’s revenues. A few months back, it had also bought telecom consulting firm Logan Orviss International.
