The continued growth in IT services and its customers resuming spending on new equipment has helped to fuel the improving figures.
The company, which also counts Lloyds Banking Group as a customer, said it was benefiting from cost cuts made in 2009, when the business slashed spending on new technology in response to the economic downturn.
Chief executive Mike Norris said: “Customers are refreshing, upgrading, improving and investing in their IT infrastructures and we are well placed to meet these needs.”
“In 2010 we have seen strong product revenue recovery and we anticipate that product revenue will grow steadily in 2011, subject to the overall economic environment.”
The group said revenue for IT services grew six per cent, while product sales grew by 13 per cent excluding the disposal of its trade distribution arm at the end of 2009.
Analysts expect the group to post a 29 per cent rise in pre-tax profit to £62.6m with a range of £61 to £66.3m.
Last year the company landed a lucrative contract to move all staff at international law firm Eversheds onto iPads.
The company, which is based in Hatfield, Hertfordshire, has also seen revenue rises in France and Germany as it expands its international operations.
