Northern Ireland telecommunications firm Rainbow has signed a new £250,000 contract with Express Distribution Services (EDS) in Lurgan.
EDS previously used a range of telecoms providers, but has now switched all its telecoms services to Rainbow Communications.
The deal includes online tracking of all EDS vehicles, live tachograph, monitoring of driver behaviour and the provision of over 50 SIM cards.
David Neill, managing director at EDS, said: "We encountered a number of issues including losing a lot of customer contacts from calls 'getting dropped' when being transferred - clearly an issue which needed to be resolved in our effort to provide a first-class service for our customers.
"As a busy distribution service with over 70 staff across two depots including 37 drivers on the road, it became increasingly business critical for us to find a more reliable and cost effective solution to our telecoms requirement."
Rainbow Communications employs over 100 staff in Northern Ireland and works with over 40% of Northern Ireland's top 200 companies. The company is based in Belfast and also has offices in Dublin and Glasgow.
In June 2014, the firm acquired the UTV Connect customer base, bringing its list of customers to over 10,000 businesses.
Over the years, the company has worked with Coca-Cola, Phoenix Gas, Central Government, Eason, and Murdock Group.
Rainbow Communications founder Eric Carson started out in the trade as an apprentice engineer at Telephone Rentals.
He left the firm after 30 years, and went on to establish TSI, which then became Rainbow.
