A-PLANT is introducing paperless dispatching across its delivery and service f leet.
The firm claimed to be the first hirer to introduce such technology company-wide.
A-Plant is issuing 1,000 electronic 'personal delivery assistants' to fitters and drivers in a £2.3 million investment.
The hand-held devices, developed with A-Plant's software provider MCS, have been trialled at a number of depots.
The first location to go live is the Trenchless Technology depot in Staines, Middlesex.
The PDAs record delivery information such as dispatch times, locations and signatures, as well as invoices and statements. The devices feature satellite navigation and communication.
Andy Wortley, A-Plant's director of IT applications, said: 'We have the industry's most advanced PDA system.'
