Get three books.
Book 1: canvassing. I use a simple code:
nt - no thanks
ag - already got
l - leaflet (return to these at later date), don't dismiss anyone until you have actually spoken to them face to face as this is key to a compact round equating to less down time.
Q- Quoted.
Second book for actual quotes:
Name, address, phone number and window count. Quote for fronts and whole house, write it down as it will be a valuable reference tool for future quotes of similar properties. When they turn into work put them in book 3
Book 3:
Cleans - agreed date of clean, name address and phone number. Seperate page for each road.
Don't over stretch yourself. I agreed to 4 first cleans last week and my timekeeping was terrible. Try to go for a simple AM or PM appointment as you raise expectations when you say you'll be there at a certain time and turn up late. I had 2 of mine phone me to say they were waiting in specially. Felt a right numpty.
Also, they will respect your professional opinion on frequency, but remember there is safety in numbers.
I currently aim for 4 hours actual cleaning time and when I finish a clean I canvass the neighbours, I recommend familiarising yourself with the 'Jones' approach ie mention subtly that you are cleaning their neighbours windows and let phsychology do the rest.
IMHO of course.
FWIW
