Split Shipment — When One Order Ships in Multiple Packages (2025 Fulfillment Decision Guide) Updated Dec 2025

Source: Shopify Help Center (split shipping & multi-location fulfillment), Amazon Seller Central merchant-fulfilled performance policies, and OMS/WMS order routing execution standards (2024–2025).

What Is Split Shipment?

View definition

Split shipment refers to a fulfillment outcome where a single customer order is intentionally shipped in two or more packages. This usually happens when items are stored in different locations, become available at different times, or must meet delivery-performance requirements.

Quick answer: A split shipment occurs when an order is fulfilled through multiple packages to protect delivery timelines or resolve inventory constraints, even though it increases shipping cost and operational complexity.
“If a cart includes items which can't be fulfilled in a single shipment, then fulfillment splits into multiple shipments.”

Who Typically Encounters Split Shipments?

View common fulfillment contexts
  • Amazon FBM / SFP sellers: shipping what is ready protects performance metrics.
  • Shopify merchants with multiple locations: inventory is allocated across nodes.
  • Brands using an OMS + 3PL: routing logic prioritizes SLA compliance.
  • Cross-border or regulated SKUs: handling constraints require separation.

What Operators Actually Care About

View operational expectations
  • Ship-by compliance without late-shipment penalties.
  • Cost control when orders split frequently.
  • Status consistency across OMS, WMS, and platforms.
  • Fewer missing-item claims and disputes.
  • Clean reconciliation for partial shipments and returns.

Common Split Shipment Scenarios

View real-world scenarios
  • Amazon FBM: one order spans multiple warehouses.
  • Amazon SFP: partial release protects tracking and ship-by metrics.
  • Shopify multi-location: automatic allocation splits fulfillment.
  • Preorder + in-stock: available items ship first.
  • Special handling SKUs: constrained items ship separately.

Decision Signals: When Split Shipment Makes Sense

View decision guidance
  • Use when: delaying the full order risks SLA violations.
  • Avoid when: margins are thin or single-delivery experience matters.
  • Trade-off: faster delivery at the cost of higher freight and ops load.

Risk Radar (2025)

View failure modes
  • Cost escalation: multiple parcels inflate freight and handling.
  • Status divergence: one package updates while another fails.
  • Missing-item claims: partial delivery perceived as loss.
  • Inventory drift: partial allocation without rollback.

Split Shipment FAQ

Is split shipment a mistake?

No. It is a policy-driven decision used to protect delivery timelines when inventory or availability constraints exist.

Does split shipment increase shipping cost?

In most cases, yes. Multiple packages increase freight and handling unless constrained by routing rules.

Do platforms penalize split shipments?

Platforms penalize late shipments and invalid tracking, not the number of packages.

Split Shipment Policy Review

In multi-warehouse environments, split shipment should be governed by explicit policy rather than default behavior. Reviewing routing thresholds, cost ceilings, and reconciliation controls helps prevent margin leakage and customer disputes.
