there seems to be some descrepancy between me and some of my customers as to what should be included when i give them the price for lawn mowing. Do u guys include trimming all the grass and weeds that grow up thru the cracks in the sidewalks/driveways with the regular mowing price, or is that something else? i'm not sure what i should do w/ this, but my gut instinct is to consider that a separate service, because trimming all the cracks in the driveway/sidewalks can get time consuming doing it every week. This would mean i would need to jack up the price in order to maintain the same profit margin on each customer. What do u guys do?
