What app do you use to keep your schedule?
I am searching for one that allows for setting up a number of days. Like 10 days or 21 days. All I have seen offer the options of daily, weekly, bi-weekly, monthly.
This is gonna be no help, but this is what I do.
I have a list of all my customer addresses saved on a Microsoft Word document on my computer.
Every Monday morning I type up which customer needs mowing for that week, and on which day. Then I print it off and treat it as a check list. It also helps me keep track of my gross earnings for when I type it into Microsoft Excel later in the day.
I keep these "checklists" until they're about a month old, so I know who got mowed the last time, and also proof of payment (for my sake).
I have never forgotten a customer. Not once.
