There are differing viewpoints on this.
I dont collect at all if I can help it!
I get people to post a cheque. I have on ave £700 outstanding, but during the month most come in. Nobody owes me more than 2 cleans.
However, if cash flow is tight, as it was for me when I first started, then I recommend you collect first of all as you finish work, if you work till 5 o'clock most people are starting to come in. Then between 7:30 - 8:30 (Eastenders time).
I never collected Saturdays as this is family time, plus, if the mans home he begrudges paying and says he will do them. (he never does)
