Been tradding for a couple of years and need to make a decision about where I take the business from here. Window cleaning is not my full time job, it gives me about three days a week which is about as much as I can handle. I've got someone starting next week, that should allow me to take on a few more customers (or drop my workload a bit). What I need to decide is; is it worth making the investment in a van and wfp setup? Even with a wfp setup I would not want to be working more than two or three days per week, if it was my full time job it would be a no brainer. What I need to know is how much extra can I realistically be expecting to earn with the wfp setup?
