Commissions were hard to estimate or predict, so you never know what your paycheck is going to be. Clients were never happy. Nearly every business that I converted to a customer came back to me with complaints wishing they could get out of the contract. One business was charged before his equipment arrived and the refund took weeks to generate. The sales strategy I was coached to implement was very "pushy". I get it - it's sales. But it was not for me.
