I maintain a huge amount of research into the call centre operators which operate within The UK and those which operate outside of The UK but service the UK marketplace. These include client lists and other information which would be of relevance to their competitors.
I also conduct specific research assignments and provide expert advice based on a huge number of criteria. This includes the following which may be helpful to win business against your competition
(1) Details and reasons for lost clients
(2) Likely pricing structure
(3) State and level of relationship which exists between the call centre and client(s)
(4) Target account list and priorities
In short, I either have or can find specific information on any outsourcing company you require. There is of course a cost associated with this information and I do not publish it on the internet. If you would like to purchase such research, please contact me on 077400 96598
