Poor inventory management is the #1 reason Amazon sellers lose money—either from stockouts killing sales or overstocking racking up fees.
At InfoBeam Solutions, we’ve helped 500+ sellers optimize inventory for maximum profitability. In this guide, you’ll learn:
✔ 9 proven inventory management strategies
✔ How to avoid Amazon’s costly storage penalties
✔ Tools to automate and scale efficiently
Why Amazon Inventory Management Matters
🚫 Stockouts = Lost sales + Lower rankings
🚫 Overstocking = Long-term storage fees (up to $6.90/cubic foot/month)
🚫 Stranded inventory = Dead capital
💡 Smart inventory management can:
✅ Reduce storage costs by 30-50%
✅ Increase in-stock rate to 98%+
✅ Boost profitability by optimizing cash flow
9 Amazon Inventory Management Best Practices
1. Forecast Demand Accurately
🔹 Problem: Guessing leads to stockouts or dead stock.
🔹 Solution:
- Use Amazon’s Restock Inventory tool + third-party tools (e.g., Forecastly)
- Factor in seasonality, trends, and promo calendars
- Adjust for Amazon sales velocity changes (e.g., Prime Day spikes)
📈 Pro Tip: For new products, start with 3-month sales data before forecasting.
2. Maintain 4-8 Weeks of Inventory
🔹 Ideal stock levels:
- Fast-moving ASINs: 6-8 weeks
- Slow/seasonal ASINs: 3-4 weeks
- New launches: Start with 4 weeks, adjust fast
⚠️ Avoid: Holding >90 days of inventory (triggers long-term fees).
3. Optimize FBA Shipments
🔹 Problem: Small, frequent shipments increase costs.
🔹 Solution:
- Use Amazon’s “Send to Amazon” (STA) bulk shipments
- Ship 3-4 weeks of stock at once (reduces per-unit costs)
- Choose lowest-cost carriers (UPS vs. FedEx vs. Amazon Partnered)
📦 Cost-Saver: Palletize shipments when possible (50% cheaper than small parcels).
4. Monitor IPI Score Religiously
Amazon’s Inventory Performance Index (IPI) (0-1,000 scale) affects storage limits:
- <400 IPI: Storage restrictions apply
- >600 IPI: Unlimited space
✅ Boost IPI by:
✔ Reducing stranded inventory
✔ Increasing sell-through rate
✔ Fixing listing problems (e.g., suppressed ASINs)
5. Automate Repricing & Purchasing
🔹 Tools to Use:
- RepricerExpress (Avoid price wars + stay Buy Box eligible)
- RestockPro (Auto-PO generation based on sales)
⚡ Pro Tip: Link repricing to inventory levels (raise prices when stock is low).
6. Prevent Stranded Inventory
🔹 Common Causes:
- Listing suppressed (missing info, policy violations)
- Expired/FBA-uneligible products
✅ Fix:
- Check Fix Stranded Inventory dashboard weekly
- Use automated alerts (via SellerCentral or tools like SellerBoard)
7. Liquidate Slow-Movers Fast
🔹 Options for dead stock:
- Amazon Outlet (Discount deals)
- Liquidations.com (Bulk buyers)
- Donations (Tax write-offs + no removal fees)
💰 Pro Tip: It’s better to recover 20-30% via liquidation than pay storage fees.
8. Diversify with Multi-Channel Fulfillment (MCF)
🔹 Problem: Relying only on Amazon = risk during stockouts.
🔹 Solution:
- Use MCF for Walmart/eBay/Shopify orders
- Keep emergency stock at 3PLs
🌐 Stat: Sellers using MCF see 15-25% higher inventory turnover.
9. Audit Amazon’s Fees Monthly
🔹 Hidden costs to check:
- Storage overage fees
- Unnecessary fulfillment fees (incorrect size/weight)
- Disposal/removal fees
🔍 Tool: Use Amazon Fee Analytics (Seller Central) or ProfitBandit.
