Blue Frog
Thats why i insisted they used my own contracts. it clearly lays out the guide lines.
I had a canvasser recentely think he can edit these sheets and try and find an angle on me :

needless to say he didn't get the cash for that!
If all you get from the person on the door is a name, address and telehpne number your asking for trouble.
The problems i had was. one offs. people only wanting a quote only and them being signed up as a custy. con roofs being included in the price (which i had to clean free of charge sometimes as its there word against ours). Not knowing about WFP or the system
With my own sheets it eliminates all these problems and they are on a 3 month contract.
Its more long winded on the door but at least i know i will have minimal issues when it comes to having the work handed over
