It really depends on your area, but in many ways yes. By the letter of the contract I can't expand past what I am given territory wise. Now I have gone outside of that, but with the permission of the guys who I am treading on their territory. Sometimes territories can be laid out dumb. Mine starts about 2 miles from my house, and between me and there is a shop that I go to. It is in another guys territory but seriously I drive passed it EVERYDAY, so it makes no sense for him to go there.
I won't say I am making a killing, but I am paying the bills. And that includes paying off a DSLR camera and an 08 Snowmobile. So I guess I am doing decent. Hope it picks up though. I am also an odd salesman. I am not pushy, and don't have a killer instinct. It hurts me a lot of times, but my customers respect me as an honest straight-up business man who isn't gonna sell the next young kid that comes along a cart before a horse.
Just sucks to be that way sometimes cause I walk into shops and see a young guy with some big expensive Snap-On box they didn't need, paid too much for, and they never even talked to me about it. Why? Cause I don't hound them telling them they need a box to be a real tech.
