Hey guys just getting ready to start my 2nd stint in the Lawn Care Biz. In your opinion, what has been your best way to estimate lawn maintenance costs. When I worked with my dad 10+ years ago we used to guesstimate and charge by the size of the yard. I know in many circumstances in this day and age that is not very economical or competitive. Do most of you go by square footage...calculating it with a measuring wheel and that sort of thing?? I know there is some handy software out there these days ie. Acculawn but is it worth it? TIA for all your input!
