Spar wholesaler Appleby Westward Group and ADM Londis have improved efficiency by replacing paper-based ordering systems with voice-activated picking technology.

Error claims at AWG have fallen 97% since the system was installed at its regional distribution centre in Saltash, saving more than £100,000 a year.

"We expect a rapid payback on the project," said AWG's operations and IT director Philip Brewer.

ADM Londis claims the cost of running its central warehouse and distribution facility in Johnstown, Co Kildare, has been cut by €300,000 a year .
