Configure automatic order splitting to fulfill orders from multiple fulfillment centers when inventory is distributed across locations.
When your inventory is distributed across multiple fulfillment centers, Jetpack’s Order Auto Split Rules automatically split B2C orders to prevent fulfillment delays and optimize shipping. Choose between Partial Shipment Rules (which split orders when no single fulfillment center has complete inventory) or Product-Based Shipment Rules (which split orders based on specific product criteria).
By default, when an order contains SKUs or units that are not all available in one fulfillment center, the order defaults to Exception status until one fulfillment center can fulfill it entirely. Enabling Partial Shipment Rules prevents fulfillment delays by automatically splitting orders across centers when needed.
B2C orders only: Both Partial Shipment and Partial Backorders rules apply only to B2C orders
Separate billing: Each split shipment is billed separately, with details visible on the Shipment Breakdown panel in the order details
Maximum shipments: By default, orders split into a maximum of 2 shipments. This can be customized to 2, 3, 4, or 5 shipments, based on available fulfillable inventory
Packaging exceptions: Orders will not split if they include items with specific packaging requirements (e.g., marketing inserts, Prop 65 labels, custom packages)
Custom Dunnage can be split as its own shipment. Adjust the Maximum Number of Shipments Per Order setting to avoid this.
Partial Shipment Rules will not split orders if any of the SKUs are out of stock (OOS). To allow orders to split when SKUs are OOS, enable Partial Backorders Rules.When items are OOS, available SKUs ship as one order, while the order remains in Exception status until the backordered inventory is replenished. Once OOS items are restocked, the order automatically moves into Processing status, provided no other exceptions exist.Example:If an order includes:
SKU A at Fulfillment Center X
SKU B at Fulfillment Center Y
SKU C at Fulfillment Center Z
This would require three shipments (one per fulfillment center). You can manually split the order in the dashboard if you prefer to ship available SKUs immediately.
By default, order splits are restricted to fulfillment centers in the same country as the customer. Override this by enabling the International Shipments setting.
Ensure the maximum number of shipments setting corresponds to the number of fulfillment centers you use for optimal operation.
Only Account Owners and Client Admins can configure partial shipment rules.
1
Navigate to Rules
From the Jetpack dashboard, click Orders on the left-hand navigation bar. Additional menu options will appear. Select Rules.
2
Configure settings
You will be redirected to the Partial Shipment Rules page, where you can adjust settings including international shipments and the maximum number of shipments per order.
Product-based split rules are configured by combining one of three conditions with one or more types of Product-Based Shipment Rules. Orders are automatically split after they are imported into the dashboard.
There are 3 conditions for Product-Based Shipment Rules:
Condition
Description
Apply to All Inventory
This condition allows for the rule to split all B2C orders imported into your Jetpack dashboard into multiple shipments regardless of their source, but we will exclude internal transfer orders (ITOs) and B2B orders.
Match Specific Inventory IDs
This condition allows for the rule to split B2C orders imported into your Jetpack dashboard into multiple shipments based on specific inventory ID(s) included in the order.
Match Products Using Keywords
This condition allows for the rule to split B2C orders imported into your Jetpack dashboard into multiple shipments using keywords that appear at the beginning or end of the product’s name.
Example: If your products are Cat T-Shirt and Dog T-Shirt, configuring the keyword as “T-Shirt” will allow orders containing these products to split.
This rule splits orders into multiple shipments to ensure each shipment does not exceed a predefined maximum unit count:
Splits orders into multiple shipments to ensure each shipment does not exceed a predefined maximum unit count
Bundles in an order may be split, causing items within a bundle to ship separately. To keep all items in a bundle together, use the Keep Together Grouped Inventory rule
Shipments created by this rule can include other products not governed by the rule, as its primary goal is to limit dangerous goods (DG)/HAZMAT products due to safety regulations and carrier restrictions
To prevent SKUs covered by this rule from shipping with other SKUs, consider using the Separate From Non-Matching Inventory rule
Allows orders to split into multiple shipments while ensuring one shipment contains the entire bundle (or a group of inventory IDs and the total units required for each).
Multiple Product-Based Shipment Rules can be enabled at once to create sophisticated order splitting logic.Example 1: Limiting Quantity and Separating ProductsYou can combine the Max Matched Quantity Per Shipment and Separate From Non-Matching Inventory rules to ensure orders contain a maximum of 2 units of Product A and Product B, while ensuring Product A and Product B are never shipped together (or with other products in the order).Example 2: Preserving Bundles While Splitting OrdersTo preserve bundles (allowing them to ship together), you can use Match Specific Inventory IDs combined with Max Match Quantity Per Shipment, Separate from Non-Matching Inventory, and Keep Together Grouped Inventory.
Product-Based Shipment Rules affect all B2C orders imported into your dashboard. Orders split based on these rules are in Processing or Exception status.
You can enable multiple Product-Based Shipment Rules simultaneously. However, Partial Backorder cannot be enabled without enabling Partial Shipment Rules.
Orders imported via certain integrations (like Shopify) will have additional tracking details visible on the Order Details page.
Add-on rules (in combination with split rules) allow custom packaging to be assigned to shipments after being split.Using the packaging’s inventory ID or a keyword (located at the beginning or end of the item name), Add-on rules will:
Review the products and total units per product already in the shipment
Add specified products and total units based on the rule configuration
Example: If you have a Product-Based Shipment Rule configured to split all shipments containing exactly 1 unit of “Cat T-Shirt” into its own shipment, an Add-on rule can be used to add your “Custom T-Shirt Mailer” to only those shipments.
