Until the end of last year I had customers on frequencies that they asked for, ranging from 2,4,6,8,12 weekly, as well as others who want them done as and when, plus the weekly shop fronts that I do.
It worked fine until I started to be so inundated that it became unworkable. From the beginning of this year I standardised the frequency of the 4,6 and 8 weeklies to 6 weekly. I didn't inform any customers but no-one has said anything. The shops of course remained the same, as did the one 2 weekly that I have. The 12 weeklies fit in with the schedule nicely too.
This created some gaps in my schedule, but I have found that my income has, if anything, increased due to actually being able to fit work in where before some areas were skipped when I couldn't keep up. I have a lot of ad-hoc customers which fill in any gaps as required, along with gutter cleans.
