Imagine This…

You’re reviewing your Amazon sales reports one evening. Orders are coming in fast, but suddenly, you realize your top-selling product is running out of stock. You rush to reorder, but delays mean you’ll miss out on sales—and next month, you’re overstocked with slow-moving products, draining your profits with storage fees.

Low inventory levels can lead to a significant drop in sales, with research indicating a potential 42% decrease when stock availability falls from 90% to below 30%. Additionally, even a single day of being out of stock can take up to four days to recover full sales momentum.

Managing inventory can feel overwhelming, but with the Seller Labs’ software and the right strategies, it doesn’t have to be. Let’s explore how you can master your inventory, avoid common pitfalls, and maximize profits in 2025.

2025: The Year You Take Control of Your Inventory

Amazon’s marketplace offers vast opportunities, but it also comes with challenges like fluctuating demand, high storage fees, and stiff competition. Here’s how effective inventory management helps:

Increased Sales: Prevent stockouts and boost your product rankings.
Cost Reduction: Avoid overstocking and reduce FBA storage fees.
Improved Customer Satisfaction: Ensure timely
deliveries with healthy stock levels.
Higher Seller Ranking: Maintain high in-stock 
rates to improve visibility.

1. Forecasting Demand and Avoiding Stockouts

Accurate forecasting is the foundation of inventory success. Use historical data, seasonal trends, and tools like Seller Labs’ Restock Application (Keep reading to learn more about this app!) to stay ahead.

  • Forecast with Confidence: Anticipate demand during peak seasons (like Q4 or Prime Day).
  • Safety Stock: Always keep a buffer to cover unexpected surges.

Pro Tip: Adopting a Just-in-Time (JIT) inventory model can minimize storage costs—but it requires precise coordination to avoid stockouts during supply chain disruptions.

Don’t miss out on the new trends as the e-commerce landscape continues to evolve. These will redefine how you think about inventory management in the coming year.

  • AI and Automation: Machine learning and AI-powered forecasting tools are essential for maintaining optimal inventory levels, helping sellers avoid costly stockouts or overstocking.
  • Distributed Warehousing: Sellers are diversifying storage locations to reduce delivery times and mitigate logistics disruptions.
  • Sustainability Initiatives: Reducing excess inventory and using eco-friendly packaging is becoming a consumer expectation, making it crucial for brands to adapt.

With these trends in mind, Seller Labs offers tailored tools to help sellers stay ahead of the game.

Here are some challenges every Amazon seller should plan for—and how to avoid them:

5. Strategies for Scaling with FBA and FBM

Balancing FBA (Fulfillment by Amazon) and FBM (Fulfillment by Merchant) can give you greater flexibility.

  • FBA: Use it for fast-moving products, but be mindful of storage fees for slow sellers.
  • FBM: Useful for lower-turnover or bulky products that incur high FBA fees.

Pro Tip: Leverage Amazon’s Multi-Channel Fulfillment (MCF) to fulfill orders from other platforms using your FBA inventory.
