Warranty and after sales handling define the long term reputation of a Flux 4 line.
Every serious sourcing conversation about the Flux 4 eventually arrives at warranty and after sales, usually because it is where cost and risk meet.
Cash flow is the quiet constraint behind warranty and after sales: the cheapest option is rarely the one that frees the most working capital.
