Shopify Order Routing Rules: Locations and Split Shipments

Shopify order routing rules prioritize eligible fulfilment locations when an online order arrives. The sequence matters: each rule operates on the result of the previous rule. A store can reduce split fulfilments, favor a destination market or prioritize a warehouse, but no rule can conjure stock at a location that cannot fulfil the order.

Understand the default sequence

Shopify's routing explanation describes these default rules, applied from top to bottom:

Other configurations may reflect a store's prior settings or manual changes. Inspect the actual rule list before diagnosing a particular order. Straight-line distance is not driving distance or a guaranteed delivery-time calculation.

Work through an example

A customer orders a mug and a shirt. Warehouse A is closer but has only the mug. Warehouse B is farther away but has both products and is in the same destination market. Under the default priority, minimizing splits can favor B before the proximity rule is applied. If no eligible location can fulfil the complete order, Shopify may split the fulfilment; other configuration and inventory conditions also matter.

To prioritize specific warehouses, add Use ranked locations and group locations in the desired order. Locations in the same group share a rank. Shopify's setup guide recommends using the closest-location rule later to break ties when appropriate.

Check location eligibility first

Before changing priorities, confirm that each location is active, has accurate available inventory and is configured to fulfil online orders. An unverified address can prevent proximity calculations. Shopify also notes that when a customer's address cannot be matched to coordinates, the proximity rule can be skipped and an older location used instead.

Shipping profiles and zones affect which delivery options can be offered; they are not interchangeable with routing priority. Review both when a valid location or rate seems missing. The multi-location inventory guide and mixed-cart shipping profiles explain the surrounding setup.

Test more than the easy cart

Create a small matrix before editing live rules:

1. One item stocked at every eligible location.
2. A multi-item cart available together only at a farther location.
3. A cart requiring more than one location.
4. A destination in a different market or shipping zone.
5. A product that is out of stock or permitted to oversell.

For each, record the expected source, observed assignment, package count, displayed delivery options and actual operational cost. Use permitted test orders and cancel or refund them according to your test procedure. Check that the warehouse team receives the expected fulfilment request.

Measure the trade-off

Fewer packages can lower packaging and handling, but a distant warehouse might have higher freight costs or a slower delivery promise. Ranked warehouses can protect retail-store inventory, while proximity can improve some deliveries. Compare shipping spend, split rate, processing time and late deliveries by scenario rather than assuming one rule optimizes every outcome.

Assign an owner to review routing after adding a location, changing a market or switching fulfilment providers. Document the original order of rules so you can restore it if the pilot creates unexpected splits.
