whatever you think your hourly rate is its a lot lower than you think.its misleading.
hourly rate "on the glass" or the whole time you spend on your business?
dont forget the filling up/messing with equipment,writing and printing invoices/worksheets,collecting,canvassing etc ,etc.
take your earnings over the course of a year minus expenses and tax and itll be a lot lower than you think.
no holiday/sick pay.days off for bad weather.you know the score.
window cleaning as a sole trader is a good job for an uneducated,unemployable guy like me who loathes the thought of working 5 days a week for someone else!but lets not get carried away!!
its ok but none of us will become millionaires doing this job!!it gets tedious and boring as well at times and its hard work!!

it also takes years to develop a good solid round that you can rely on to give you a half decent income.
saying all that i love it and ive managed to make a good steady income out of it.
