For those of you who have a Full Time Irrigation tech. (e.g. someone who's FT job each and every day is to repair irrigation systems) and who work out of a Van or Enclosed Trailer or Truck that is stocked with parts, here's my question for you; Do you charge for your time when you have to leave a jobsite and go get a part that you don't have with you in your van? Just curious how others deal with this. We do bill our customers for this time because we stock 95% of what you would find in most irrigation systems. But there are all sorts of obscure parts that we don't carry. So I figure we try our best to stock most of the stuff, and if we have to go get something obscure, we're gonna charge for that time.
