A frozen food courier is not a transport business with a fridge bolted on. It is three businesses running at once — a machine that holds temperature, an evidence system that proves it held, and a control tower that knows what every stop costs. Most operators build only the first; the other two ambush them through claims, audits, and margin collapse. This is the field guide to all three: the engineering, the evidence, and the economics of keeping frozen food frozen across South Africa.
