Order splitting management
Order splitting lets B2B Plus break a single customer order into multiple sub-orders or shipments based on inventory availability, rather than forcing the whole order to wait on its slowest line item. A line that is available Immediately can ship right away, while lines drawn from Future or Prebook inventory are split off into their own shipment, scheduled against the ship window configured for that stock.
This behavior depends on the Orders Read scope described in API scopes ("Read orders and split orders"), which must be enabled on the store's API credential for splitting to be available to external integrations.
Once enabled
- Orders containing a mix of Immediate and Future/Prebook lines are automatically evaluated for splitting rather than held as a single shipment.
- Each resulting sub-order inherits the ship window relevant to its inventory bucket, using the Default and Minimum Ship Window lengths configured in Shipping windows.
- Fulfillment, invoicing, and payment can then be tracked separately per split shipment through the Orders Write, Invoices, and Transactions scopes.
Order splitting is closely tied to the Ship Windows and Inventory Dates settings in Configure shipping windows—review those defaults first, since they determine the shipping timeframe each split sub-order is scheduled against.
