You should be aware that customers care and will often compare your price to the listed price. While you may work off your invoice price and calculate your overhead and setup costs the customer has to work with what is available to him or her.
Most of us work with cost, plus - like Neil does, but I agree that MSRP is the only reference point that the customers have. That being said, our quote system shows MSRP, the actual discount in dollars and the final price on each piece of equipment. The system allows us to show any and all additional fees (freight, set-up, etc.) but it also can be built into the tractor and/or implements - and will not show as separate line items. My preference is to show all fees, so as to be able to properly explain everything to my customer.
Sorry, but after re-reading this entire thread I had to make a couple more comments - any John Deere National Account Sale (AQHA, NTRA, USEF plus
many others) are "delivered" by the dealer and "sold" by John Deere Company. The very deep discounts are usually below our cost and we get a small "set-up credit" to do the actual work - in most cases this ends up being a break even, slight loss or slight profit for the dealers. The idea behind the National Account program (Deere's idea, at least) is that these units will be out and "seen" by many people - which is why the program is so strict on who is allowed to use it. AQHA, for instance, if you look back in the post, is
available for full-time horse operations, professionals, breeders and trainers - not for the family with 4 or 5 acres and a few horses... Last point, and I have posted on this before - John Deere margins shrunk a few years back and, unless there is a special program going on - 20% discounts off MSRP are a thing of the past. Without any special programs from Deere, 15% off MSRP is going to be about the best you can do. Of course factor in a unit that has been on the lot for a year, or a unit that has a redesign coming out soon - things like that always make a difference.
Anyway, just my two cents!
