Computer company Information System Networks has bought up a software sales firm which could add £750,000 to its annual turnover.

The company, based at Abingdon Science Park, has bought up Runcorn-based Simply Business Systems, which sells accountancy software systems.

ISN has taken on all of the firm's employees, including former managing director Chris Cowling, who becomes a senior consultant.

ISN managing director Bob Haacke said: "We were looking to develop business in the north west and we couldn't have found a better match in terms of the range of skills, experience and company culture.

"We will be working closely together to build on the success while ensuring that our northern client base enjoys all the advantages and additional resource which ISN brings."

Mr Haacke set up ISN in 1987 offering a range of services from supplying and maintaining computer hardware and networks to programming and finance systems. The firm also has branches in London, Leicestershire and Warrington.
