Forrester Research reports that customer e-commerce spending will lead the IT spending charge in 2004, growing by 4.8% this year. Buy-side e-commerce spending will grow by 1.9%, projects Forrester. In fact, Forrester estimates that three-fourths of companies will maintain or increase their IT spending for e-commerce initiatives. Forrester bases its estimates on the survey of 212 e-commerce decision-makers. In-Stat/MDR estimated last month that small business IT spending totaled $161 billion last year and would reach $215 billion by the end of 2008.
