Thanks so much for responding, but your suggestion hasn't helped as I don't select any service item when doing timesheets. I have attached a screenshot of what I am trying to change - the billable hourly rate shows as $65 - this is the figure that I want to change. I can change it each time I do a timesheet, but it is pre-set somewhere & I want to update it. I hope this makes sense. I have spent ages trying to find where to update it.
