Xero is moving its North American conference from the fall - the time of year the first and so-far only show was held - to the spring of 2015. The New Zealand-based cloud software company held its first conference in the United States in September 2013 but will not be holding another this fall. "We heard from a lot of our accounting partners that the spring is a better time for them than the fall," says Sharna Brockett, Xero's director of public relations and social media in the United States.
