Most customers (which is the more appropriate way of describing the companies you service or may want to service some day) that have in-house technicians have been acquired from local dealers, usually these tech's are the more experienced types trained by the dealers you work for. Average hourly charge in the Phoenix area currently is $105 were the customer's burden rate for in house tech's range from $70.00 - $ 80.00 per hour. Sometimes it makes sense to farm out and sometimes it makes sense to have in house and sometimes it makes sense to combine both. It's important the dealers supply good support to the customer from parts delivery, sales, product support and qualified techs. One other thing for the younger dealer tech's out there. Please follow the safety rules set forth by the customer while you are on their property. These rules may seem unimportant to you but most have real meaning and all are important!
