I never collect as a rule, Just post a slip and custies either pay online or send a cheque, Obviously quite a few pay on the day if they are in. My round is spread over quite a distance, So it would not be very practical for me to go collecting. I too have had my fingers burned going over 2 cleans without being paid, So now 2 cleans is my limit, If its a new custy I will sometimes only do 1 clean if I feel they are a bit dodgy. Getting everyone to pay on the week of their clean is unrealistic, It will not happen, As Dazmond says August is a bad month for cash flow (This is my first year and am finding this out). I think at least 30-40% of the cleans I have done this month, the customers are away on hols.
