Amazon Sellers Urged to Optimize FBA Inventory to Cut Costs

Imagine carefully preparing a shipment of goods, eagerly sending it off to an Amazon FBA warehouse, only to discover that your inventory has been divided and sent to multiple locations. This scenario, known as split shipments or "distributed inventory placement," can increase transportation costs, delay restocking timelines, and disrupt sales plans. Many Amazon sellers have faced this logistical challenge. So how can you minimize split shipments and ensure your products reach designated warehouses efficiently?

This article explores Amazon's FBA split shipment mechanisms and provides practical inventory configuration strategies to optimize logistics and reduce operational costs.

Understanding Amazon FBA's Split Shipment System

Amazon's Fulfillment by Amazon (FBA) program handles storage, packaging, and delivery for sellers, streamlining e-commerce operations. However, to enhance delivery efficiency, Amazon may distribute a seller's inventory across multiple warehouses based on various factors—a process called "split shipments."

Default Setting: Distributed Inventory Placement

By default, Amazon uses Distributed Inventory Placement. When creating a shipment plan, Amazon might allocate products (even identical ASINs) to different FBA warehouses. This strategy aims to reduce delivery times and improve overall logistics performance.

Optional Service: Inventory Placement Service

Amazon offers an Inventory Placement Service for sellers who prefer consolidated shipments. Selecting this service ensures all inventory for a specific ASIN is sent to a single FBA warehouse. Sellers then ship goods to this designated location, while Amazon handles subsequent distribution.

Choosing the Right Inventory Configuration Strategy

The optimal approach depends on your specific needs and product characteristics.

Advantages of Distributed Inventory Placement:

  • Faster delivery: Products stored near buyers arrive quicker, improving customer satisfaction.
  • Lower shipping costs (for small items): Lightweight, compact items may incur reduced shipping expenses when distributed regionally.

Disadvantages of Distributed Inventory Placement:

  • Higher shipping costs (for large items): Bulky or heavy products often face significantly increased transportation expenses when split.
  • Complex logistics management: Managing multiple shipments and warehouse inventories adds operational complexity.

Advantages of Inventory Placement Service:

  • Simplified logistics: Shipping to one warehouse streamlines the fulfillment process.
  • Controlled shipping costs: Particularly beneficial for large or heavy items where consolidated shipments reduce expenses.

Disadvantages of Inventory Placement Service:

  • Additional fees: This service carries extra costs.
  • Potentially slower deliveries: Centralized inventory may extend delivery times for distant customers.

Practical Tips to Minimize FBA Split Shipments

Even with Inventory Placement Service, split shipments may still occur. Consider these strategies to reduce their likelihood:

  1. Understand Amazon's allocation rules: Policies evolve based on warehouse capacity, demand, and geographic factors. Regularly review Amazon's updates.
  2. Optimize product dimensions and weight: Standard-sized, lightweight items are less likely to be split.
  3. Maintain uniform product types: Avoid mixing dissimilar products in one shipment. Group similar items when necessary.
  4. Ship larger quantities: Bulk shipments are less prone to splitting than small batches.
  5. Utilize Amazon's inventory tools: Tools like Inventory Placement Reports identify split-prone products, helping adjust shipping strategies.
  6. Study warehouse locations: Shipping to Amazon warehouses near your location may decrease split shipments.
  7. Consider third-party logistics: Some 3PL providers offer FBA-specific solutions to better manage shipments.
  8. Mind size variations: Identical products in different sizes (e.g., standard vs. oversized) may route to separate warehouses.
  9. Note service limitations: Inventory Placement Service only prevents splits for individual ASINs—mixed ASIN shipments may still divide.

Frequently Asked Questions

Can I select which FBA warehouse receives my products?

No. Amazon automatically assigns warehouses based on internal algorithms.

Does Inventory Placement Service guarantee no split shipments?

Not always. Multi-ASIN shipments or non-standard product dimensions may still cause splits.

How do I check my shipment's destination warehouses?

In Seller Central, navigate to "Manage Amazon Shipments," select the relevant plan, and click "Track Shipment" to view warehouse destinations.

Conclusion

Minimizing Amazon FBA split shipments requires a multifaceted approach. By understanding allocation rules, selecting appropriate configuration services, optimizing product specifications, and leveraging available tools, sellers can enhance logistics efficiency, control costs, and improve sales performance.
