Kettering-based Total Computers logged revenues of £65.5 million in this financial year.
The figure is a 25.7 percent rise on the previous year and is quintuple the £13.7 million the HP and Lenovo partner turned over in 2010.
Operating profits also surged from £1.22 million to £1.77 million.
The company has been expanding like topsy over the last few years, but its results plateaued just above the £50 million mark in 2016.
Managing director Aidan Groom said that the firm’s growth resumed after winning some more significant projects thanks to its service skills.
Most of the growth took place in the public sector, and corporate sales sector but the company was winning more big-ticket deals than ever before, thanks to improvements to its technical capabilities and services offering.
As a result, first quarter 2018 sales were “well up” on the previous year.
