Same with us. We talk to the vendors, place the orders, review the specs, deal with everything - but we don't do the reselling so that we can be neutral. I think that there are more people doing that than vendors realize and a lot of business shifts to vendors that work well with that ecosystem.
Meraki, for example, gets almost no attention from vendors like us because they try so hard to take over the whole thing. They basically cut us out of the process leaving the customers without any means to deal with them because we are the only ones that handle that stuff.
