Funny enough I do know someone that actually does this,it makes no sense to me but If we are all honest it must cross people’s mind when they pull up to quote.
Like I’ve said before I price on what I want for a particular job not per window or time there within reason,if the job was £40 in my head if it was going to cost me another £40 job getting there and getting back it would be 80 and so on,if you price per window and don’t factor things like travelling in etc you’ll kill yourself on price.
I’ve made this mistake many times over the years with pricing,I know a lot of people who price per window when I look at a certain job they may be doing or have done if I’ve ever added up pricing per window it’s always come in way under why I’d charge.
If you price what you’re happy with and not per window etc you should always be happy enough ,IMO the worst way to price is by the hour how many windows can you clean in an hour,a huge amount when I last looked lol.
