Right them up and tape them to your desk area on what to do. I have a PW job and today I got another one from a windy customer so will do both in same day when I have the PW in van. Today, I did 2 softwash jobs when I have all the stuff in the van. That's the way I do it but I only have 100 odd windy customers so have time to do it. I also have a diary but as I clean windows monthly so its not that hard to know what I'm doing at the beginning of each week.
