In 2008 whilst acting as Head of Legal for an investment bank, Iain Sheridan developed  a Time & Complexity billing algorithm. This form of alternative legal fee billing calculates legal fees based on the type of work, its complexity and the notice given to complete the task. Time & Complexity billing was first published as an article in New Law Journal on 6 June 2008.
