not to sound funny richy, but you can only take a window cleaning business so far, it is after all it is only cleaning windows, the prob i see with this business is loads of people think they are alan sugar and want to do something bigger and better, they think there is a magic formula that will make every custy want them, they buy all the best gear going all brand new vans, then moan they aint making money as all they do is pay out,
i believe there is a ceiling for the majority of people with what they will pay to have there window cleaners,
sometimes the best thing to do is not think what else can i do to make it better, but actually look at the business, and sort it out, sack staff, stop buying new vans, dump crap payers, reduce the area you work in prehaps you need only you and one staff and do all the best jobs you got and rent the other out
i got a mate who had 4 vans each makeing 3.5 k a month last year, now he is down to him making 1.5 in one van, big time dreamer, cant run a business, payed crap wages,
