Automatically Split Orders

ShipStation's Auto-Split feature will split orders into multiple shipments based on the products included in the order. You can specify how you want Auto-Split to create these shipments in the Product Details for each of your products. This automation happens at the same time as Auto-Routing and before any other type of automation.

Auto-Split helps you save time managing orders that contain products with unique shipping requirements, such as:

  • The order contains an oversized item, like a mattress, bicycle, etc.

  • The order contains products from different warehouses

  • The order contains a product that is on backorder

  • The order contains a product with a unique shipping requirement, like shipping with dry-ice

Your product records will have four options for the Auto-Split feature:

  • Do not auto-split this product

  • Exclusive Bulk Shipping: Creates a single new shipment for the specified product for the full quantity in the order. For example, if an order has a quantity of 2 for one of the products, Auto-Split will create one new shipment for the 2 items.

  • Ships Individually: Creates a new shipment that will contain a single quantity of the specified product. For example, if an order has a quantity of 2 for this product, Auto-Split will create a separate shipment for each.

  • Ship on Custom Quantity: This option allows you to specify the number of items that should be in each shipment.

The Auto-Split settings are located in the Product Details under the Shipping tab. You can edit the Auto-Split behavior on each product individually or for multiple products at a time.


  • Your account must either be on the High Volume subscription plan or you must activate the Auto-split add-on for your account.

Notes about the Auto-Split Feature

  • Once you set a product auto-split, this setting will apply to any new order imports from your store or from a CSV.

  • Auto-Split does not apply to new manual orders or previously imported open orders.

  • Auto-Split automation runs before Product Preset Groups, Product Defaults, Service Mapping, and Automation Rules.

  • Any new updates on orders from stores will not apply to orders after Auto-Split.
