Key takeawaysWhat replenishment isInternal replenishmentExternal replenishment What replenishment is Replenishment has two meanings: (1) internal — moving goods from the reserve (bulk) area into picking locations when they drop below a threshold; (2) external — placing purchase orders to suppliers to replenish overall stock. Internal replenishment Picking locations have limited capacity. When stock in a location drops below the minimum, the WMS generates a replenishment task from bulk so pickers never run out. External replenishment Based on the reorder point = consumption over lead time + safety stock. A good system triggers orders automatically, matching real demand with available stock. How Azuvio helps Combining sales (OMS, marketplace, retail EDI) with WMS stock, Azuvio computes per-SKU reorder thresholds, generates internal replenishment tasks and proposes purchase orders — simultaneously cutting stockouts and overstock. Frequently askedDifference between internal and external replenishment?Internal = moving from reserve to picking locations in the same warehouse. External = a purchase order to a supplier to replenish total stock. Both prevent stockouts, at different levels.How is the reorder point calculated?Reorder point = average consumption over the lead time + safety stock. When available stock reaches this level, a new order is placed.Can replenishment be automated?Yes. A WMS/OMS auto-triggers internal replenishment tasks and proposes purchase orders when stock hits the threshold, based on real demand synced from all channels.
