I worked at Zones for 3 yrs. I was #2 in my Region for all 3 yrs. I had a brand new territory with no existing business when I started. You will need to be a scrapper because IF you think that upper Mgmt will help you to land big accounts, think again.
When I brought Mgmt in to help me win a large deal in a new account, worth 50% of my annual quota, they criticized me for all sorts of things that THEY "thought the client needed" even though we were only focused on what the client told us they needed. Once Mgmt got involved, there were too many people talking to my client vs. going thru me. This confused the customer and my 9 mos of work almost went out the window. Then when we landed the deal, Mgmt told me that they had to retract 40% of my commission based on "the resources that they had used" to win the deal- I'm not talking about price or discount.
This company is close to be a real contender but then they play with the commission plan which disincentivizes sales people, they don't give enough training to the Product Specialists- so they aren't up on the newest things, they give a lot of recognition to the same "old boy" network without looking at who is helping them expand the company in cities outside of Company Headquarters etc.
If you are considering Zones, take what they tell you in benefits and Engineering support and cut it in half. Consider SHI or working directly for Dell, Cisco, EMC before Zones..
