Excelguru is a consulting firm led by Ketil Øyesvold Melhus, a psychotherapist and systems developer whose common denominator for the two professions is diagnosis. The firm offers professional Excel help to customers who can choose between getting a fixed price or renting the firm for shorter or longer periods. Fixed prices are typically provided after assessing the job and are deemed fair and reasonable. Melhus’s experience as a former leader and owner of Datatjenesten AS for 30 years has given him experience in business processes, project management and financial management. The specialty of Excelguru is project or financial reports that are linked directly to the SQL-based economy system so that customers can get their favorite report directly from the solution without cutting and pasting. Melhus has a good understanding of the databases for Visma Business, Visma Global and coming up on Business Nxt.
