- How to understand "Direct Factory Supply"? What are its advantages?
- "Direct Factory Supply" means the seller or channel directly cooperates with factories possessing large-scale production capacity, bypassing middleman wholesaler links. The main advantages of this model are:
- More stable quality: Large factories have complete production lines and quality control systems, enabling end-to-end control from mold opening to finished products, ensuring more reliable product quality.
- More competitive pricing: Eliminates price markups from middlemen, usually resulting in better prices.
- Relatively reliable supply: Direct connection with factories ensures higher supply stability, and some may even get priority access to popular new releases.
