Choosing One Provider, or More? As a Telecom Expense Management (TEM) Project Manager, clients usually ask my opinion on which provider to choose, who offers the best deals and equipment. Working for a TEM company – I am naturally neutral regarding providers. Yes, equipment-wise, I have my favorites - which, incidentally, change as fast as the new “toys” are released on the market. Regarding costs, I see some excellent corporate contracts, good ones and really awful ones. Contract negotiation is one aspect of “eggs-in-a-basket” to be covered in another blog.
