The pie chart below breaks down the newsagency sites installed by my software company, Tower Systems, over twelve weeks to yesterday. 50% have come from one competitor, 25% are greenfield locations and the rest spread between 3 competitors. To lose close to 20 clients in twelve weeks must be hurting one competitor. The newsagents have all switched for common reasons. While we knew we were doing well, we have not been watching enough to know how well.
