Factory-Owned Vendor vs Trading Vendor
Trading vendors resell with added margin and limited engineering depth. A factory-owned vendor quotes from the production line, answers technical questions directly and controls quality.
For buyers comparing vendors, the factory-owned model delivers better price, traceability and support.
