"per mowing" is why I always sell a contract. Its 30 mows a year, $250 per mow , 7500 total, divided by 7 months $1,071 per month. This prevents the EOW switcheroo. Oh you want EOW 'suddenly'? thats a whole new contract. $550 per mow, 16 mows, $8800 per year, divided by 7 months $1258 per month. What? It's not cheaper!.. No, no it's not. IF you don't write contracts for mowing . ALWAYS quote BOTH on the SAME piece of paper, make them sign the bottom and initial next to their choice. $250 for 5-7 day service interval $550 for 10-14 day service interval. Pick one.
