Air Bar Zen 4 Inventory Replenishment Explained
Published 2026 · VapeWholesaleHub trade desk
Inventory replenishment discipline is what separates profitable Zen 4 distribution from busy distribution.
Buyers who treat inventory replenishment as a commercial discipline rather than an afterthought tend to hold margin for longer.
Seasonality interacts with inventory replenishment more than most forecasts allow for, so a rolling review beats an annual one.
Why inventory replenishment matters on the Zen 4
Reorder points should reflect lead time plus safety stock, not intuition.
In practice the decision comes down to three numbers: unit cost, freight per unit and the realistic sell through rate for Zen 4.
Fast movers deserve shorter review cycles than long tail flavours.
