Managing inventory costs is one of the most critical aspects of running a successful Amazon FBA business. For sellers, it directly impacts profitability, cash flow, and the overall sustainability of the company. Here are detailed tips to help you effectively manage your inventory costs and optimize your accounting processes.
Understand the Types of Inventory Costs
Inventory costs can be classified into four main categories:
Purchase Costs: The cost of acquiring your inventory, including product costs and shipping to Amazon warehouses.
Storage Costs: Fees Amazon charges for storing inventory in its fulfillment centers. These are often overlooked but can quickly add up, especially for slow-moving products.
Fulfillment Costs: Fees Amazon charges for picking, packing, and shipping orders.
Hidden Costs: These include returns, damaged goods, and unsold inventory disposal fees.
Tip: Keep a clear record of all these costs in your accounting system. Using accounting software tailored for eCommerce or hiring an Amazon FBA accountant can streamline this process.
Track Inventory Turnover
The inventory turnover ratio measures how often inventory is sold and replaced over a specific period. A high turnover rate indicates strong sales, while a low rate could mean overstocking or poor product demand.
Tip: Use tools like Amazon Seller Central’s reports or third-party inventory management software to track turnover. Aim to restock only what you can sell within a reasonable timeframe to avoid excess storage fees.
Optimize Reordering Practices
Effective reordering ensures you don’t run out of stock while minimizing excess inventory. Overstocking can lead to higher storage fees and tie up your cash flow while understocking can result in lost sales.
Strategies to Implement:
Set Reorder Points: Determine the inventory level at which you should place a reorder based on sales velocity and supplier lead times.
Use Automated Tools: Leverage inventory management software that integrates with Amazon to send alerts when inventory levels drop below a specific threshold.
Negotiate Supplier Terms: Work with your suppliers to secure discounts or more flexible payment terms to improve cash flow.
Leverage Amazon FBA’s Inventory Performance Index (IPI)
Amazon measures your inventory management through the IPI score. A low score can lead to storage limitations, while a high score provides flexibility.
How to Improve Your IPI Score:
- Remove excess inventory by running promotions or liquidation sales.
- Ensure you replenish fast-moving inventory promptly to avoid stockouts.
- Regularly reconcile your inventory records to ensure accuracy and avoid discrepancies.
Analyze Storage Fees
Amazon FBA charges storage fees based on the volume and duration of stored inventory. Long-term storage fees, which apply to items stored for over 365 days, can be particularly costly.
Tips to Reduce Storage Costs:
Classify Inventory by Age: Use Amazon’s reports to identify slow-moving items. Prioritize selling older inventory through discounts or bundles.
Monitor Seasonal Trends: Stock up on seasonal items ahead of demand spikes but avoid holding excess inventory after the season ends.
Leverage Removal Orders: If items aren’t selling, use removal orders to retrieve inventory or dispose of them to avoid long-term fees.
Accurately Record COGS (Cost of Goods Sold)
COGS refers to the direct costs of producing or purchasing the goods you sell. Accurately tracking COGS is essential for calculating your profitability and preparing for tax season.
Steps to Record COGS Accurately:
- Keep detailed records of product costs, shipping fees, and any additional expenses like import duties.
- Update your accounting system whenever new inventory is purchased or sold.
- Use inventory valuation methods like FIFO (First-In, First-Out) or weighted average cost to calculate COGS.
Forecast Demand
Accurate demand forecasting helps prevent both overstocking and stockouts, which can be costly.
Methods for Effective Forecasting:
- Analyze historical sales data to identify trends and seasonality.
- Monitor industry trends and adjust your inventory levels accordingly.
- Use forecasting tools or work with an accountant who specializes in eCommerce to make data-driven decisions.
Reconcile Inventory Regularly
Discrepancies in your inventory records can lead to inaccurate financial statements and missed opportunities.
Best Practices for Reconciliation:
- Compare your inventory records with Amazon’s reports at least monthly.
- Investigate discrepancies immediately to identify issues like lost or damaged inventory.
- Utilize software that integrates with Amazon to automate reconciliation processes.
Factor in Hidden Fees
Amazon FBA charges several additional fees that can impact your overall inventory costs.
Common Hidden Fees to Watch:
Returns Processing Fees: Costs associated with processing customer returns.
Removal Order Fees: Charges for removing unsold inventory from Amazon’s warehouses.
Unplanned Prep Fees: Costs incurred if inventory isn’t prepared according to Amazon’s requirements.
Tip: Include these fees in your accounting system to ensure accurate cost analysis.
Invest in Inventory Management Tools
Investing in the right tools can save you time and reduce costly errors.
Recommended Tools:
InventoryLab: For inventory tracking, cost analysis, and profitability reports.
Helium 10 or Jungle Scout: To forecast demand and identify top-performing products.
QuickBooks or Xero: For accounting tasks, including tracking inventory-related expenses.
Outsource Accounting and Inventory Management
If managing inventory costs feels overwhelming, consider outsourcing to professionals. An Amazon seller accountant or FBA consultant can help optimize your operations and identify cost-saving opportunities.
Plan for Taxes and Write-offs
Inventory costs significantly affect your taxable income. Ensure you understand how inventory expenses are treated for tax purposes.
Tax Tips:
- Record inventory purchases as assets initially, and expense them only when sold.
- Track write-offs for damaged or unsellable inventory.
- Work with an accountant who understands Amazon FBA tax rules to maximize deductions.
Monitor Cash Flow
Inventory ties up a significant portion of your cash flow. To avoid financial strain, balance your inventory investments with other business expenses.
Tips to Improve Cash Flow:
- Diversify your suppliers to minimize delays and cost fluctuations.
- Focus on selling high-margin products to maximize returns.
- Consider short-term financing options if cash flow becomes tight during peak seasons.

Amazon regularly updates its policies regarding inventory storage, fees, and performance metrics. Staying informed can help you avoid unnecessary penalties and make strategic decisions.
