Key points

Revenue: £67.1m (+4%)

Net profit: 0.4%

Staff: 130

This Southampton-based HP and Vodafone partner packed an additional £3m onto its top line in its year ending 31 May 2017 despite "streamlining" its sales team. Net profits fell from £358,000 to £288,000, however, as an investment in a sleek new website and the relocation of its London sales office pushed up overheads. In May 2018, mid-market-focused Vohkus bagged Titanium partner status with Dell EMC.
