It improves speed, reduces split shipments, and lowers cost-to-serve—without any custom code or developer setup. ### Key capabilities * **Fulfillment Health Score**: Diagnose fulfillment efficiency across cost, speed, reliability, and split rate. * **AI Recommendations**: Get automated suggestions to improve fulfillment rule performance. * **Parallel Simulations**: Run up to three test scenarios against your live setup before deploying changes. * **Dynamic Activation**: Push optimized rules into production with one click. * **Continuous Monitoring**: Receive new insights as conditions and performance evolve. Deployable in minutes using the [Shopify Integration](/v3/integrations/shopify/overview) — no engineering support required. For more information about Smart Order Routing, see the [Smart Order Routing](/v3/orders-and-inventory/user-guides/orders/smart-order-routing/overview) page. ## Dynamic Reallocation & Cancellation Rules Introducing a flexible, low-code interface for configuring business logic to automatically handle fulfillment disruptions—like location outages, stock anomalies, or weather events. ### Key capabilities * **Rule-Based Automation**: Define logic that automatically reallocates orders or updates inventory. * **Conditional Triggers**: Match on event types, reason codes, or system signals. **Flexible Action Set**: * Reallocate orders to alternate locations * Adjust location-level inventory * Temporarily suspend locations from routing logic For more information about dynamic reallocation & cancellation rules, see the [Reallocation and Cancellation Rules](/v3/orders-and-inventory/user-guides/orders/configurations/reallocation) page.
