Answers:    Neither. You need to consider what services are one contracted for. You then determine what are your costs for supplies labor etc. Then set the price. The customer should not supervision how you derive the price, only if they are feeling like to pay for the service.
I owned a janitorial service surrounded by california for 20 yr. The biggest mistake people variety starting in the business is beneath chargeing just to return with the job.
