unless I can drive to the customers in 15 / 20ish mins.(or its a mega job where the travelling time is sort of in the job)
I will charge from the when the van starts moving from home, or last job .......... to home or next job.
They way I look at it, if you drive an hour to do a job (ok rare, just an example) it takes an hour to get back, and say the job took an hour....that whole job has taken 3 hours not 1 .
Of course if its a it customer with nice knockers , you obviously wave the travelling charge
