Man hour rate x total man hours = service price man hour rate should factor in dump fees and time spent at the dump. If dump related cost is not factored in to your man hour rate then an additional charge should be applied to the job in addition. Always try to fully communicate all pricing with customers before starting the job that way there are no surprises for the customer. You don't want to spring on an additional dump fee without letting them know that there will be an extra cost up front....don't be like large cable companies no one NO ONE! Likes that.
