Collecting in the mornings! no chance they are all in a mad rush to get to work.
I have printed my bank details on my cleaned your windows slip for the last 2 months, up to now I have converted just 4 customers to pay on line.
I have 6 days work on one estate alone, I only collect on Thursday nights. As Tosh said, I need a certain amount of cash flow too. On some estates I leave envelopes and get a good response.
One interesting fact with these, If I write the customers name and amount owing on the inside of the envelope flap, I get 90% response, if I just leave my cleaned your windows slip in the envelope, I get nowhere near the same success rate.
I believe this is because you are placing the onus to pay on the named person, you address them personally. If you just leave your slip, she will leave it for him to pay, and he will leave it to her.
