on average how many billable hours do you get out of a landscape crew? say there clocking in at 7 and leaving at 5. I bill for all travel time unless were at the same job for a few days and then only charge one way. how much is wasted on coffee/bathroom breaks shop time ect...?? If all jobs took exactly 4 or 8 hr's that would be great. it seems like a lot of time evaporates that I end up paying for.
