Im thinking of doing the Payroll course and exam. Is there any money in this? Ive tried checking out how much bookkeepers, accountants payroll bureaus charge and there is a big variation. For a sole trader with 3 employees would £20 per month be reasonable? Would orhers charge this for monthly pay and would this be the same if employees were paid weekly? Ive seen that basic software costs £15 per month but there is free softwear available.
