If you can handle the pressure you can be very successful as a territory sales rep...
Pros
Flexible hours, potential for great pay, amazing people to work for. If you do well and network well there is room for growth. I like the company a lot, just not my position and it is different to make lateral movements in terms of entry level opportunities. The benefits, especially the profit sharing, are phenomenal. More relationship based than transactional, which is great except Grainger marks items up so much that you must discount items to win the business which comes straight out of the sales rep's pockets.
Cons
The base pay is pretty low and if you don't hit your goal you lose hundreds of dollars in commission by no fault of your own. About 30% turnover and it is clear if you don't make goal for the year there is little chance that you will be promoted. It is difficult to get out of the sales track and you're paid significantly less than account managers even though territory sales reps have hundreds of more accounts. The goals are extremely aggressive in the Chicagoland area and don't take into account one time project and hits that you can't count on the next year. You are evaluated every month so I feel like I'm starting from scratch every month. Overall it's a great sales job, but only if you can handle the extreme pressure of having to hit your numbers every single month. It is easier if you come into a "healthy" territory or one where it wasn't neglected by the precious rep.
