Cleanability
When you say "for cleaning a carpet in about an hour" I assume you referring to one hour actual time at the job.
What about travelling to and from - the time and running costs of van, and I dont just mean fuel.
And what about time cleaning your equipment, the hoses, the filters.
By the time you added those factors in, plus real costs like income tax, national ins, the pension pot, bit for holiday pay, bit for sick pay, advertising, time spent book keeping, business insurance, cost of cleaning fluids, put aside for the time you have to but new pump or vac motor etc etc etc...... the list goes on. And of course with only looking at the time charged whilst at the job you tent to forget the hours waiting for the phone to ring to enable you to earn anything.
I think £80/£90 is getting more realistic by the day.
Unfortunately, rarely do I hit it..... need a rethink.
but there again how many clients will be able to pay it.
