Order splitting occurs when a single customer order is fulfilled in multiple separate shipments. This can happen because items are in different warehouse locations, have different availability dates, or for fulfillment cost optimization.
Why Orders Are Split
Inventory Reasons
| Reason |
Example |
| Multi-location |
Items in different warehouses |
| Partial availability |
Some items in stock, others not |
| Different suppliers |
Drop-ship items |
| Backorder |
Waiting for replenishment |
Optimization Reasons
| Reason |
Benefit |
| Faster delivery |
Ship available items now |
| Lower shipping cost |
Ship from nearest location |
| Meet deadlines |
Partial fulfillment beats delay |
Types of Order Splits
Location-Based Split
Order: Items A, B, C
Item A: Warehouse CA
Items B, C: Warehouse TX
Result:
- Shipment 1: Item A (from CA)
- Shipment 2: Items B, C (from TX)
Availability-Based Split
Order: 5 units Widget
Available: 3 units
On backorder: 2 units
Result:
- Shipment 1: 3 units (ships now)
- Shipment 2: 2 units (ships when available)
Supplier-Based Split
Order: Brand A product + Brand B product
Brand A: Ships from our warehouse
Brand B: Drop-shipped from vendor
Result:
- Shipment 1: Brand A (our warehouse)
- Shipment 2: Brand B (drop-ship)

Split Order Fulfillment
Process Flow
Order received
↓
System checks inventory locations

Determines optimal split
↓
Creates fulfillment orders
↓
Each location picks/packs/ships
↓
Customer receives multiple packages
Coordination Challenges
- Multiple locations involved
- Timing synchronization
- Communication to customer
- Tracking consolidation
Minimizing Splits
Strategies
- Inventory positioning - Stock where demand is
- Consolidation - Wait and ship together
- Alternative sourcing - Transfer inventory first
- Customer choice - Let them decide
When to Avoid Splitting
- Low-value orders (shipping cost > benefit)
- Customer requests consolidated
- Fragile items (multiple handlings)
- Gift orders (prefer single package)
