Can anyone give any tips on how to run a smooth, stress free business? Or any tips to make the running of a business a bit easier?
When you have sufficient work, free yourself from the customers who try to be overly controlling about when and how you may clean their windows, the ones that you find persistently irritating, the ones who try to haggle the price, and the ones who you sense will bump you for the money (you get a nose for this stuff after a few years though you will never get it right every time).
I know it may sound like there won't be many customers left after such filtering but that is not the case. However, it can take a few years of regular pruning to get a round like the above.
