For just DMS or for all things IT? We're still on "If it doesn't work, you are using it wrong" Reynolds blue screen, just DMS, my cut is right around $950. All things IT, I'm closer to $2,500 too.
Which DMS are you on? Also do you know what your expenses split is? (i.e. 25% new, 30% used, 30% service, 15% parts).
