Tesco, Sainsbury and Iceland are set to adopt technology which will ease stock control and communication with suppliers. The move involves a central database of product information which can be accessed, via the internet, by suppliers and retailers. It enables suppliers to enter changes to product specifications and add new lines to the database. David Armes, Tesco director of b2b ecommerce, said it was negotiating access to Udex's stock control technology. Sainsbury's b2b trading development project manager Stephen Boles said it was working on a similar deal. {{NEWS }}
