Number crunchers from public sector consultant Tussell said that the software reseller won £328 million worth of government contracts making it the largest IT-dedicated supplier to the government last year.
Generally it ranked behind four other organisations: defence contractor QinetiQ (£359 million), outsourcer Mitie (£514 million), infrastructure provider Amey (£641 million) and Rolls-Royce (£776 million).
The reseller’s positioning was boosted by the award of a £150 million NHS Windows 10 contract last year.
The outfit has been targeting a range of public sector organisations from the very smallest educational establishments to the goliaths of the NHS and the MOD.
Last year saw it growing in security, Microsoft Cloud solutions, Windows 10 and in more recent months, AWS.
A company spokesperson said that these areas will continue to be significant drivers for consolidation and increased productivity for the next few years.
More than £49.5 billion worth of contracts were handed out by the public sector last year, with IT and telecoms accounting for eight percent of this figure.
