How to manage inventory levels on Amazon

Author:

Effectively managing inventory levels on Amazon is crucial for ensuring product availability, maintaining customer satisfaction, and optimizing profitability. Poor inventory management can result in stockouts, excess stock, and negative customer experiences. Here’s a comprehensive guide to managing your Amazon inventory levels efficiently:

1. Set Up Inventory Tracking Systems

The first step to managing inventory effectively is having a system in place to track your stock. Amazon provides tools and reports to help you keep track of your inventory levels and sales performance:

  • Amazon Seller Central: The Inventory Dashboard in Amazon Seller Central provides an overview of your stock, including the quantity available, inbound inventory, and any listings that are out of stock.
  • Restock Inventory Tool: Amazon’s Restock Inventory tool helps sellers forecast future inventory needs based on historical sales data, seasonality, and trends. This tool calculates your replenishment needs to prevent overstocking or stockouts.
  • Third-Party Software: For larger sellers or those managing multiple channels, consider using third-party inventory management software like TradeGecko, Cin7, or SkuVault. These tools provide real-time tracking, streamline stock alerts, and sync inventory levels across various platforms.

2. Use Fulfillment by Amazon (FBA)

Fulfillment by Amazon (FBA) is a service that can help simplify inventory management by offloading storage and shipping tasks to Amazon. With FBA, Amazon stores your products in its fulfillment centers, and when a customer places an order, Amazon picks, packs, and ships the product.

Here’s how FBA can help you manage inventory levels:

  • Storage at Amazon Fulfillment Centers: You send your products to Amazon’s warehouses, and they handle the storage, packaging, and shipping. This allows you to focus on other aspects of your business while Amazon manages your inventory.
  • Real-Time Inventory Updates: FBA automatically updates your inventory levels, helping you monitor stock availability across Amazon’s platform.
  • Automatic Replenishment: FBA can notify you when inventory levels are running low, helping you avoid stockouts.
  • Multi-Channel Fulfillment: FBA also allows you to sell on other platforms, such as your own website, and still use Amazon’s fulfillment services to manage and ship orders.

3. Set Replenishment Alerts

Regular monitoring and reordering are essential to avoid stockouts. You can set up alerts to notify you when your inventory levels fall below a certain threshold. Here’s how to do it:

  • Inventory Settings: In Amazon Seller Central, you can set your Restock Threshold for each product. This threshold helps you determine when to reorder products to avoid stockouts.
  • Automatic Restocking: For items with high turnover, consider setting up Automatic Replenishment through FBA or using third-party tools that provide automated restocking based on sales velocity.

4. Forecast Demand and Plan for Seasonal Variations

Accurately predicting demand and accounting for seasonal fluctuations is critical for avoiding both stockouts and overstocking. Amazon’s Restock Inventory tool can help you forecast future demand, but you should also consider these factors:

  • Sales Velocity: Analyze historical sales data to understand how quickly products are selling. If your product is trending or has a sudden surge in popularity, you may need to adjust your inventory levels accordingly.
  • Seasonal Trends: Many products experience seasonal spikes in demand. Plan ahead for holidays or peak seasons (e.g., Black Friday, Christmas, Back-to-School). Ensure that your inventory levels reflect seasonal demand shifts, and place orders with suppliers well in advance.
  • Promotions and Events: If you plan to run promotions or participate in Amazon’s deals (e.g., Prime Day, Lightning Deals), anticipate a spike in sales and increase inventory levels accordingly.

5. Monitor Inventory Health Metrics

Amazon provides performance metrics that help you assess the health of your inventory:

  • Sell-Through Rate: This metric measures how quickly your products sell relative to how much inventory you have on hand. A high sell-through rate indicates strong sales and efficient inventory turnover.
  • Days of Supply: This shows how long your current stock will last based on your sales velocity. It’s important to maintain an adequate supply to avoid running out of stock.
  • Excess Inventory: If you’re holding more inventory than you can sell, Amazon may charge higher storage fees, especially for long-term storage. Regularly monitor your excess inventory to prevent this.
  • Inventory Age: Amazon tracks how long products have been in its fulfillment centers. Long-aging inventory may be subject to long-term storage fees. Aim to rotate your stock frequently and reduce the number of slow-moving products.

6. Conduct Regular Inventory Audits

Regular audits help ensure that your listed inventory matches your actual physical stock. Inaccurate listings can lead to overselling or stockouts, negatively affecting your seller account health.

  • Reconcile Online and Offline Stock: Periodically check your inventory levels on Amazon against your physical stock. This ensures that your listings reflect what’s actually available.
  • Inventory Reconciliation with Suppliers: When dealing with suppliers, ensure you’re getting timely and accurate updates on incoming stock. Regular communication with suppliers helps ensure that inventory levels are replenished on time.
  • Implement Barcode Scanning: If you’re not using FBA and handling fulfillment yourself, consider investing in barcode scanning technology. This streamlines the process of tracking and updating your inventory.

7. Optimize Listings to Avoid Overstocking

Sometimes, poor sales velocity or inaccurate listing information can lead to overstocking. To prevent this:

  • Improve Product Listings: Make sure your product listings are optimized with high-quality images, accurate titles, bullet points, and keywords. Well-optimized listings are more likely to attract buyers, leading to faster sales and better inventory turnover.
  • Competitive Pricing: Price competitively to encourage sales. If your product is priced too high, it may not sell, leading to excess stock. On the other hand, pricing too low can erode your margins. Analyze your competition and adjust your pricing accordingly.
  • Consider Bundles: If you’re struggling with excess inventory on individual items, consider creating product bundles. Bundles can help you sell more products together and improve your inventory turnover rate.

8. Utilize Amazon’s Inventory Management Reports

Amazon provides several inventory reports that help you manage your stock efficiently:

  • Inventory Age Report: This shows the age of your products in FBA warehouses and helps identify slow-moving items.
  • Restock Report: A detailed report that helps you determine how much inventory to send to Amazon’s warehouses based on your sales velocity.
  • Reserved Inventory Report: This shows how much of your inventory is reserved for pending orders, helping you track real-time availability.
  • Amazon Sales Dashboard: The dashboard provides detailed insights into sales trends, helping you predict future demand and make informed decisions about inventory replenishment.

9. Deal with Stockouts Proactively

If you find yourself running low on stock or facing a stockout:

  • Set Up Backorders or Pre-Orders: If you know that stock is low but will be replenished soon, consider setting up a backorder or pre-order option to retain customers. This can help you capture sales even during stockouts.
  • Notify Customers: If a product is out of stock, make sure to inform customers about the expected restock date. You can also offer alternatives or similar products.
  • Analyze the Cause of Stockouts: After resolving the issue, analyze why the stockout occurred. Was it due to inaccurate forecasting, shipping delays, or sudden demand spikes? Learning from the experience can help prevent future stockouts.

Conclusion

Effective inventory management on Amazon is key to maintaining profitability and a strong customer experience. By using Amazon’s tools, tracking inventory levels, planning for seasonal demand, and responding to stockout situations promptly, you can ensure that your products are consistently available to customers, minimizing lost sales and enhancing your seller reputation. Regular audits, forecasting demand, and maintaining healthy stock turnover will keep your Amazon business running smoothly.
