B2b e-commerce will have a greater impact in the grocery retail sector than b2c, according to a new report from PricewaterhouseCoopers for the DTI. Over two thirds of 50 retailers questioned said they expected e-commerce would "transform" the way the sector operates in two years. Supply chain collaboration through sharing data on extranets is also likely to become widespread. However, some respondents feared smaller retailers would not have the money or the expertise to invest in e-commerce strategy. And some worried that some of their most profitable customers would be poached by online shopping operations. {{NEWS }}
