Other suggestions for improving rounds!
Dazmond you could try this in your area!
We have also taken on full house maintenace, by that i mean we can get £200+ for a house which includes windows gutters facia, con, windows inside/outside including frames all done on over the course of the year, this we are doing on monthly instalments works well both ways ie: £200 div by12= just over £16 a month This looks good for the customer as they were paying £10 a month just for the windows so we changed the window cleans from 4 to 8 weekly as they really didn`t need done that often, it works for us as well as we don`t have to canvass for the gutter and con/cleaning for next spring, i mean if you are looking for work for the winter now is the time to be taken customers on
As you work in a very rich affluent area this could be ideal!
Do you carry out the work in advance of the higher monthly payments?
Do you have a financial arrangement in place in case they move part way through a year? (either to get money for work already done or to provide a refund)?
How do you deal with times when you can only provide the service at a lower frequency? (e.g. snow, illness, holiday)? Or do you just make sure that customers wanting the "all-in" service are on an "a-list" to be done as priority customers?
Not trying to put a damper on things as this sounds like one of your more viable suggestions but was wondering how you would deal with the above.
