As ever, the clue as to what to write about is in the thread title...
I started window cleaning a long time ago and I discovered through trial and error the things that make / allow me clean more efficiently, none of them had anything to do with rushing around and aiming to go faster just to make more money. Like a lot of people on here it was about doing the small things which made the flow of work improve and reduce the stress overall with the objective of doing the work in less time and having some choices. So the only reason for speeding up the work rate really is that there may be other things in life (or business) you want to do rather than just cleaning the same old winderz... ALL DAY!
The best thing I ever did was keep a tight round, not letting it grow endlessly but still paying attention to the customer 'churn' rate.I went out during the working day in the time I had made for myself, sticking more leaflets through doors to get more customers.
That's how I got more money, using leaflets to drive people to my web site where I could advertise all the things we do. That led me on to up-selling oportunities, basically increasing the number of services we provide, not just cleaning but other types of property maintenance, especially seasonal work for when the days get longer.
It was through taking on board that a variety of work types is more often a better way of securing a longer term predictable increase in earnings, that I managed to get things where I wanted them to be, happy in my work.
But mainly it was about not letting the work spread into all the available time in the working day, so I still had the quality of life, for which reason I gave up what I was doing previously on an office treadmill.
Oh... and not forgetting to make time to go to Windex and see first hand what new products are available. Hmmm, there's some junk kit around, to be sure...
