Amazon Prime Day 2025 is coming this July—and for eCommerce sellers, it’s a powerful opportunity to drive sales and capture market share. With over 200 million Prime members worldwide, the demand for fast, seamless shopping experiences is higher than ever. As customers prepare for some of the best deals of the summer, sellers need to be equally prepared behind the scenes.
Prime Day is one of Amazon’s biggest annual sales events, and in 2024, it generated $12.7 billion in global sales, including a record-breaking $7.6 billion from U.S. sellers—a 6.5% year-over-year increase. With sales expected to rise even further in 2025, eCommerce brands must finalize their inventory and fulfillment strategies now to stay competitive.
Speed matters. A study indicates that 86% of consumers consider fast delivery to mean within two days, , highlighting the importance of having your warehousing, logistics, and Amazon FBA prep in place well before Prime Day. Let’s cover the key steps to ensure you’re fully prepared—so your brand can scale efficiently, sell more, and deliver without delays.
Why Prime Day Preparation Is Crucial
Avoid Inventory Stockouts
Running out of stock during a high-traffic event like Prime Day leads to immediate lost sales—and long-term algorithm penalties. Amazon’s A9 algorithm deprioritizes listings with stockouts, lowering your organic ranking and future visibility. According to a 2024 Jungle Scout report, 46% of Amazon sellers listed stockouts as a top sales-killing mistake during major sales events.
Prevent Fulfillment Delays
Late shipments don’t just hurt customer experience—they directly impact your seller performance metrics. Amazon penalizes sellers for missed handling times, especially during events like Prime Day. Maintaining fast and reliable delivery improves your Buy Box eligibility, which can increase sales by over 82%, according to Amazon.
Stand Out in a Crowded Market
With over 2.5 million active sellers on Amazon as of 2025, competition is fierce. To succeed during Prime Day, your offer must ship faster, be more reliable, and appear more professional than others. Trusted fulfillment, high-quality prep, and visible customer service readiness can significantly impact conversions.
Inventory Planning for Prime Day 2025
Forecast Based on Data
Review your past Prime Day performance, peak season trends, and current market conditions. Use tools like Amazon Inventory Performance Index (IPI) to assess readiness.
Diversify Your Warehousing
Split inventory between Amazon FBA and third-party fulfillment centers like Lansil Global’s US-based warehouses. This avoids bottlenecks and gives you fallback options.
Account for Lead Times
If sourcing from overseas—especially China—factor in production timelines, port congestion, and customs clearance. Start production at least 60–90 days in advance.
Leverage Flexible Storage
Use partners that offer on-demand warehousing, allowing you to increase stock temporarily without long-term commitments.
Fulfillment Strategy: FBA, FBM, or Hybrid?
1. Amazon FBA (Fulfilled by Amazon)
- Pros: Prime badge eligibility, fast shipping, trusted logistics
- Cons: Stricter inventory deadlines, storage limits
For Prime Day 2025, inventory must be received by Amazon no later than June 20. Delays can lead to stockouts and missed sales.
2. FBM (Fulfilled by Merchant)
- Pros: Greater control over inventory, flexibility
- Cons: Requires robust third-party logistics (3PL) or in-house operations
3. Hybrid Approach
Use FBA for bestsellers and FBM for:
- Oversized or restricted items
- International SKUs
- SKUs with tighter margins
