How to Source Air Bar Box 4: Warranty and After Sales
Air Bar Box 4 · Warranty and After Sales

Warranty and after sales handling define the long term reputation of a Box 4 line.

Distributors reviewing their Box 4 range usually find that warranty and after sales explains most of the variance in results between accounts.

Seasonality interacts with warranty and after sales more than most forecasts allow for, so a rolling review beats an annual one.

Why warranty and after sales matters on the Box 4

A clear dead on arrival policy removes friction for retail partners.

Keeping a short internal note on warranty and after sales for each SKU pays for itself the first time a dispute arises over the Box 4.

Spare parts availability matters more than warranty length in practice.
