Avoid Stockouts: Prime Day 2025 Logistics Prep Guide for Amazon Sellers

Amazon Prime Day 2025 is just around the corner. To help sellers navigate the promotion successfully, we've put together a detailed FBA logistics strategy to ensure you're fully prepared and ready to maximize your sales.

Step 1: Master the Prep Timeline for Prime Day

Timing is everything. Staying aligned with Amazon's Prime Day calendar is key to gaining an edge. Save and refer to the official Prime Day 2025 preparation timeline to help you plan your shipments with precision and seize this peak sales opportunity.

Step 2: Replenish Low-Stock ASINs Immediately

If some of your ASINs are understocked in Amazon's fulfillment network during Prime Day, you may be charged low-inventory-level fees. Worse, your products might not be placed in warehouses close to customers, resulting in slower delivery and lower conversion rates.

How to check which ASINs need replenishment:

Go to Seller Central → Inventory → FBA Inventory → Inventory Health → Filter “Out of Stock” or “Low Stock” → Review the suggested replenishment quantities and timelines under “Recommended Actions” → Create a new shipment accordingly.

 Pro Tip: Keep your stock levels above the minimum threshold or maintain more than four weeks of cover. Regularly assess sell-through rates based on each sales stage to avoid running out.

Step 3: Use Inventory Pre-Management & Storage Management Tools

Warehouse space is at a premium during peak seasons like Prime Day. Without proper planning, you risk storage limits, delays in restocking bestsellers, and even missing out on promotional opportunities.

To avoid this:

• Apply early for extra storage space via the FBA Capacity Manager.
• Clear out excess or unsellable inventory in advance.
• Pre-stock through Amazon Warehousing and Distribution (AWD) — it has no storage limits and supports automatic replenishment to FBA, ensuring a smooth Prime Day with no warehouse overloads.

How to check your storage limits:

Your FBA storage capacity depends on your Inventory Performance Index (IPI), projected sales, shipment lead times, and more. Amazon announces storage limits in the fourth week of every month. New professional sellers (active for less than 39 weeks) are not subject to these limits.

You can view your usage under: Inventory Performance Dashboard, FBA Dashboard, Shipment Progress, or the bottom of “Send to Amazon (STA)” pages.

Requesting additional storage:

Use the Capacity Manager to apply for more space:

• Select storage type
• Click "Create New Request"
• Enter your desired capacity and maximum reservation fee

If granted, you can earn performance credits through the extra sales, which offset storage reservation fees.

Step 4: Optimize Inbound Planning & Shipment Speed

During Prime Day, logistics speed and fulfillment stability become critical to winning orders and customer satisfaction. FBA is strongly recommended for its efficiency and ability to lower your operational costs.

Tips for FBA sellers:

• Plan transport early – Contact your freight forwarder or logistics partner in advance to understand lead times and costs. Book shipping slots or container space as early as possible.
• Inbound appointments – All inbound shipments via air or ocean must be pre-scheduled. Work with logistics companies that are familiar with Amazon's FBA inbound process.
• Use “Ocean+Express” or “Air+Express” models – These combine ocean or air freight with local express delivery in the destination country.
• Upload tracking numbers – Make sure your freight forwarder provides last-mile tracking numbers for express deliveries and uploads them to your Seller Central account.
• Avoid configuration fees – To qualify for Amazon-optimized shipment splitting (and avoid extra configuration fees), ensure each SKU is packed in at least five identical cartons or pallets, with identical product quantities per unit.
• Batch stock to AWD – Send large quantities to AWD for automatic FBA replenishment. Products in AWD are searchable and buyable immediately, with lower warehousing costs and no storage limits.
• Use express courier services – Carriers like UPS, DHL Express, and FedEx don't require inbound appointments, allowing for faster warehouse check-ins and avoiding seasonal delays.

* Be sure to select “Small Parcel Delivery (SPD)” and the correct courier when creating your shipments in Seller Central.
