I charge a £ per payslip with a minimum £5 per week (ie upto 5 employees) for weekly runs and a minimum £20 per month for monthly runs. If it's a one man company on £476 per month, I tend to charge with final accounts at around £180 (£15 per month). I also charge extra for P35 etc (from £50 to £100) which gives a timely boost to funds at this time of year!
