I will be starting up within 1/2 months

and am just brushing up on minor things... to make sure i got everything in place

I will go canvassing and shotting flyers out ect..... when i canvass.... I will arrange a window clean within a few weeks or maybe 1 weeks time.. whenever it suits me and the customer

and when someone rings me.... i will do the same....
BUT..................
Some people let the people know that their windows are going to be cleaned now.. and this relates to byes ( come next time miss it today thankyou ) i wont be doing this at all i will just turn up and clean the windows.
When i have cleaned the window.... i will put a note through the letter box saying your windows have been cleaned i will collect the money so and so ? thankyou ect
does everyone let the customer know the windows have been cleaned ?
