Replenishment

Replenishment is the automatic reordering of continuity (core, never-out) products to a target stock level as they sell — distinct from the seasonal buy of fashion styles. It keeps basics in stock against steady demand using a model stock or min/max.

Replenishment works off a model stock: a target on-hand by size that triggers a reorder when stock falls below it, sized to demand and lead time. It is the engine behind keeping core sizes available without overbuying.

It is the counterpart to the in-season chase — chase presses into a fashion winner; replenishment quietly keeps the basics filled to the curve.
