You wouldn't have many customers then Ian.
I kept one of my rounds when I started up.
I regularly have customers owing 2, 3 or even
4 cleans, I have never not been paid by them.
When they do pay they usually pay some more
up front.
At certain times of the year you do get a lot of
non payers but as long as you put a note through
their door so they know you been it's fine.
Gives people the idea that your desperate.
Having said that I've never had only 33% of the
weeks work outstanding, usually manage to get
around 85% - 90% every time.
