Funny i did the same post when i was new to the forum!,
my answer is good and bad
i have used 2 before.you do get alot of crap
i had some horror custies ,ie they must have been told after one clean you can see if you like the service blah blah. so 2nd clean they did not pay or canceld lol stating they were told its one clean then its up to them .....when you canvas yourself you explain its a regular service strictly not a one clean you wouldnt convince someone for 10 mins you wouldnt say try me then you can cancel, but a canvaser might.
i did get my money back , but only the difference ie £25 house say you pay 2 cleans the way they look at it is you pay £50 for a monthly you get paid £25 the customer cancels for any reason and they will credit you with £25 in otherwords u work for free
and they replace £25 worth of work
Now if you get many of these cancellations or half cancellations they tend to get upset and will stop working for you forcing you to go out alone and actually get customers that want a window cleaner (which is what i recommend just do it yourself)
But on the otherhand i must say that some work was very good , some very nice customers and well priced too so it wasnt all bad
I think once you become busy you should look into maybe using a canvaser as your time on the glass will be worth more then your time canvassing if you know what i mean.
Then again it might be better to employ someone part time then it will free up your time to canvass.
now if you are not good at canvassing or dont like the idea of knocking on doors and you just dont like it (many people dont like it)
Then do some research try and pay them in 2 instalments try and give them a contract and in a nutshell if you dont like canvassing only after doing your research it may be a good move But be carefull it could also be the worst mistake you have done! its luck of the draw!
