How to read it
Revenue is pools times your monthly rate. Chemical cost is what you spend per pool per month on chemicals you don't bill separately. Hours count the time at each stop plus driving between stops, every week of the month.
If the hourly number looks thin, the usual levers are a higher rate, tighter routes (less drive time between stops), or billing some chemicals on top of the rate. See how to price weekly pool service and how many pools one tech can do in a day.
