Pickfaces only stay useful when they are kept stocked. Clarus offers three replenishment strategies that decide **how and when** stock arrives at a pickface: **Continuous**, **Demand**, and **Order Volume**. You set the strategy per location on the product's Pickface panel, and you can mix strategies on the same product when different locations serve different purposes. ## The strategies Proactive top-ups. A replenishment task is generated automatically whenever stock falls below the configured minimum trigger. Best for fast-moving stock you always want available. Reactive top-ups. A replenishment task is generated only when a specific pick task cannot be fulfilled by any other pickface — typically because of shelf-life criteria. Best for sensitive or low-frequency requirements. Demand-calculated top-ups. When a pick task is generated, the system replenishes only the shortfall between the order quantity and what's on the shelf. Best for keeping stock movement lean and tied to active orders. ## At a glance | | **Continuous** | **Demand** | **Order Volume** | | ----------------------- | ------------------------------------------------------------ | ----------------------------------------------------------------------- | --------------------------------------------------------- | | **When it replenishes** | Stock drops below the minimum trigger | A pick task cannot be fulfilled from any other pickface | A pick task needs more than is on the pickface shelf | | **What it replenishes** | Up to the maximum trigger (or full storage units if enabled) | Always a full pallet | The shortfall for the order (quantity entered on the HHD) | | **Stock allocation** | Soft allocation (standard) | Hard allocation to the replen and pick task | Calculated at pick task generation | | **Typical use case** | Standard picking for fast movers | Customer- or order-specific shelf-life requirements | Lean stock movement tied to actual order demand | | **What goes on hold** | The pick task, if no pickface meets criteria | The pick task and replen task, if no empty demand pickface is available | — | ## Choosing a strategy * **Pick Continuous** when the product moves quickly, has predictable demand, and customers don't enforce tight shelf-life rules. The system keeps the pickface topped up automatically and distributes picks across multiple locations in priority order. * **Pick Demand** when the product has customers with strict shelf-life criteria (for example, a maximum sell-by date) that the everyday pickface stock may not meet. The system reserves an empty location to receive a full pallet of compliant stock only when the order demands it. * **Pick Order Volume** when you want replenishment driven purely by live order demand rather than fixed triggers — the system tops up only the shortfall needed to fulfil the pick. See [Order Volume Replenishment](/knowledgebase/warehouse-setup/replenishment/order-volume). * **Use both** when a single product needs everyday throughput *and* occasional compliance picks. Configure a Continuous location as the primary and a Demand location as the secondary. See [Combining strategies](/knowledgebase/warehouse-setup/replenishment/combining-strategies). ## Before you start A location must already be enabled as a pickface before you can assign it to a product. See [Set up a pickface](/knowledgebase/warehouse-setup/create-pickface) for the location-level configuration. ## Related pages * [Continuous Replenishment](/knowledgebase/warehouse-setup/replenishment/continuous) — full setup and behaviour * [Demand Replenishment](/knowledgebase/warehouse-setup/replenishment/demand) — full setup and behaviour * [Order Volume Replenishment](/knowledgebase/warehouse-setup/replenishment/order-volume) — demand-calculated top-ups * [Combining strategies](/knowledgebase/warehouse-setup/replenishment/combining-strategies) — primary + secondary patterns * [Understanding On Hold picks](/knowledgebase/warehouse-setup/replenishment/on-hold-picks) — why a pick goes on hold and how it auto-releases
