Why Master Inventory Management for Amazon FBA?
Managing inventory efficiently is an extremely critical yet often overlooked aspect of running a successful Amazon FBA business. The unique fulfillment structure of FBA introduces unique complexity and risk into inventory management, which can quickly spiral out of control without vigilant tracking and oversight.
Common issues like stockouts, overstocks, storage fee hikes, and poor IPI scores can swiftly erode your business’ bottom line and even lead to account suspensions in extreme cases. Over 20% of new FBA sellers fail within the first year due to inventory mismanagement, while 40% struggle to achieve consistent growth.
The key lies in implementing robust inventory planning, forecasting demand accurately, setting buffer stock levels, and preventing avoidable costs through overstock.
By mastering the essential inventory management practices tailored to the FBA fulfillment model, sellers can optimize customer experience, boost profit margins, and build sustainable branding in the ultra-competitive Amazon marketplace.
This extensive guide summarizes the key learnings from leading Amazon experts and top-tier third-party sellers to help FBA businesses conquer inventory management, avoid unnecessary risks, and maximize success. Let’s get started.
1. Conquer Inventory Forecasting and Planning
Accurately Predict Future Demand
The crucial starting point for inventory success is understanding expected product demand accurately. Reliable demand forecasts enable you to strategically plan inventory procurement, transfers, and promotions to optimize growth and mitigate risks.
Approaches like analyzing historical sales data, monitoring market trends and competitive landscape, running predictive analytics algorithms, or building statistical models can accurately estimate future demand. Our preferred forecasting tool is Forecastly, which leverages AI and machine learning to predict demand patterns for FBA products.
While such quantitative methods work well for most types of inventory, newer product launches or seasonal items may additionally require qualitative techniques like seeking expert opinions, running customer surveys, or comparing with complementary products.
Carefully select the forecasting techniques that match your product portfolio, business maturity, access to historical data, risk appetite, and other market-specific factors. Avoid taking a one-size-fits-all approach.
Plan for Success
An inventory plan provides a detailed blueprint for managing inventory flows across SKUs based on their individual demand forecasts, trends, and seasonality.
Account for average lead times across your supply chain to prevent stockouts. Set minimum safety stock levels and reorder points, especially for high-velocity items prone to demand variability.
Develop marketing calendars and plan inventory transfers or supplementary procurements to align with promotions, new product launches, and peak seasons like Black Friday or the holidays. This prevents costly overstocks or understocks during make-or-break periods.
Continuously review and update your inventory plans as new data, trends, and seasonality patterns emerge. Building agility and responsiveness into your planning process is vital for FBA success.
2. Manage IPI Score and Avoid Storage Fees
Understand the IPI Score
Maintaining a high Inventory Performance Index or IPI score is crucial for Amazon FBA sellers. This metric tracks the overall health of your inventory by assessing key parameters like excess inventory, stranded inventory, sell-through rates, and more.
A higher IPI score helps lower FBA storage fees substantially while improving your seller rating and account health. On the contrary, a chronically low IPI frequently incurs punishing long-term storage fees of $6-$7 per cubic foot on excess stock while hampering your performance metrics and visibility.
In extreme cases of repeated violations, you may also risk temporary account suspensions and be subject to intensive audits – catastrophic outcomes for any seller.
Strategies to Improve IPI
The most effective way to improve your IPI score is through disciplined inventory control to minimize excess stocks and stranded inventory.
Regularly review granular inventory reports down to the ASIN level to identify slow-moving SKUs taking up storage space. Employ targeted promotions, bundles, discounts, or giveaways to liquidate such overstocks before they accumulate long-term storage fees actively.
Additionally, leverage inventory removal orders strategically to shift excess inventory back to your warehouses or vend through wholesale channels while avoiding extra fees and minimizing write-offs.
Further supplement these efforts by boosting sell-through rates across SKUs through well-optimized listings, improved conversion rates, and reasonable price points relative to competition. This increases overall inventory turnover velocity, driving higher IPI scores over time.
3. Optimize Stock Control and Reorder Points
Master the Art of Stock Control
Maintaining sufficient but not excess stock levels for each product is vital for FBA success, especially to keep IPI score and storage fees in check. Invest in barcode scanning devices and perform regular cycle counts while putting away inventory or fulfilling orders to improve stock accuracy.
Set optimal par stock targets for each product and track variances daily to quickly catch and resolve discrepancies. Probe sources of inaccuracies like damaged stock, misplaced inventory within the warehouse, incorrectly fulfilled orders, and more.
Consider graduated workflows enabled by feature-rich inventory management platforms that automate and error-proof major warehousing functions like receiving, stowing, picking, and shipping while providing actionable analytics.
Additionally, define buffer and safety stock thresholds beyond base target quantities to cover unexpected demand changes, forecast inaccuracies, or supplier shipment delays. Strike an optimal balance between your desired customer service levels and overstock risks.
Calculating and Setting Reorder Points
For inventory replenishment, reorder points trigger the procurement process with sufficient lead time to prevent hitting a stockout. While Amazon provides recommended reorder points, tailor these levels based on your unique supplier lead times and product velocity.
Use the following formula to calculate item-specific reorder points:
Reorder Point = (Average Daily Unit Sales x Lead Time in Days) + Safety Stock
For exceptionally high-demand items, assess inventory levels frequently and reorder well before reaching the originally calculated reorder point. This provides an additional buffer against stockouts that can severely impact your business.
4. Leverage Technology and Automation
Embrace Inventory Management Software
Sophisticated inventory management software like Cin7, Fishbowl, NetSuite, and Brightpearl seamlessly integrates with Amazon to provide centralized visibility, minimize errors, and enable intelligent planning.
Key capabilities like barcode-driven workflows, batch tracking, serial number identification, and custom reporting enhance warehouse accuracy. Route mapping, wave planning, and batch-picking features boost fulfillment efficiency.
Real-time dashboards offer transparency into inventory health across dimensions like stock levels, replenishment needs, cash flow impact, and storage fee liabilities, facilitating data-backed decisions to course-correct.
Consider free trials to deeply assess platforms that best address your challenges and scale to match future business growth regarding functionality depth, analytics, and automation capabilities.
Explore Automation Solutions
Look beyond core inventory management systems to create an integrated technology ecosystem covering other critical operations like repricing listings, triggering replenishments, and more based on projected demand signals.
Repricing engines like Feedvisor, Teikametrics, and Prisync employ AI to optimize prices 24/7 to accelerate inventory turns. Replenishment systems like Forecastly, Orderbot, and Nosto dynamically trigger stock reorders, factoring in historical patterns and predictive demand.
Evaluate complementary solutions that tightly couple with your inventory management setup to drive greater efficiency across planning, warehousing, and order fulfillment.
5. Avoid Overstocks and Stockouts
Identifying Overstock Risks
Overstocks directly impact cash flows while incurring substantial long-term storage fees that erode margins. Set reminders to analyze weekly inventory reports to calculate months-of-cover for low-velocity items across brands, categories, and warehouses.
Implement promotions, bundles, discounts, or giveaways for slow-moving stock before further storage fees accrue. Alternatively, consolidate severely overstocked inventory batches and liquidate through wholesale channels.
An ounce of prevention is worth a pound of cure for FBA overstocks – identify risks early and act decisively.
Preventing Stockouts
While far more damaging for customer satisfaction, stockouts are ultimately easier to recover from than overstocks for FBA sellers when weighing long-term consequences.
Closely track listings with higher historical sales velocity and reorder sufficiently early to cover supplier lead times and unanticipated delays. For products prone to sudden demand spikes like trending board games, seasonal best-sellers, or viral products, define generous safety stock thresholds on top of average demand.
Maintain active communication with key suppliers before peak seasons to align on prompt deliveries, priority shipments, and capacity planning.
Occasional stockouts, while painful in the short term, protect long-term profitability by minimizing the grave dangers of potential overstocks. Strike the right balance based on your risk appetite.
Conclusion
Efficient inventory control marked by disciplined tracking, planning, and risk management establishes the foundation for highly profitable FBA brands. Accurately forecasting demand, optimizing inventory flows, maintaining precise stock levels, and leveraging technology provide a robust platform for sustainable growth.
Carefully assess the detailed tips covered across core areas like inventory planning, IPI score enhancement techniques, mastering stock control, calculating reorder parameters, overstock identification, and stockout avoidance – identify those most relevant to your business.
While initially resource-intensive, investing in inventory health monitoring and planning pays rich dividends over time in the form of lower costs, improved customer loyalty, and steadier growth. So embrace a data-driven approach tailored to your product mix, risk appetite, and operational constraints for mastering FBA inventory management.
