Formally, yes — I stand between you and the supplier. But a middleman in the usual sense earns a margin inside the price, and you never see it. My fee is invoiced separately, never inside the price. Payment records to suppliers are available on request. A simple test: remove that kind of middleman, and the supplier’s price drops — the margin was sitting in it. Remove me, and the supplier’s price does not move. What falls apart is the execution.
