An area that will significantly impact a seller’s success on Amazon is inventory management. Effective inventory management involves strategic planning, forecasting, and optimization to ensure the right products are available at the right time. By adopting these strategies, sellers can improve stock control, enhance sales performance, and achieve greater customer satisfaction.
Amazon’s Inventory Performance Index (IPI) is a numerical representation of your skill at managing your inventory on Amazon’s platform. The fulfillment options available on Amazon are FBA, FBM, both FBA and FBA, onsite, or Multi-channel fulfillment. Demand forecasting is the process of predicting future sales outcomes based on historical data and is crucial for inventory management. Striking a balance between having enough stock to meet customer demand and not having excess stock sitting idly in the warehouse is pivotal to successful inventory management. Harnessing data analytics for inventory management has evolved from a competitive advantage to a business necessity. An automated inventory management system can track stock levels in real-time, trigger automatic reordering based on predetermined stock thresholds, and issue alerts for low-stock or fast-moving items. A well-organized and responsive supply chain is a cornerstone of successful inventory management and overall business performance. For brands expanding beyond Amazon to other marketplaces or their e-commerce platforms, Inventory Management for Diverse Marketplaces is crucial for maintaining efficiency and ensuring a cohesive customer experience across all channels.
Understanding Amazon's Inventory Performance Index (IPI)
Amazon’s Inventory Performance Index (IPI) is a numerical representation of your skill at managing your inventory on Amazon’s platform. Used by Amazon to gauge your inventory performance, this score determines your storage limits and eligibility for various Amazon fulfillment features. Understanding and improving your IPI can lead to several benefits, including increased storage space, reduced fees, and better product visibility, all of which can significantly impact your overall sales and profits.
The IPI score ranges from 0 to 1000, with a higher score indicating more efficient and effective inventory management. Amazon calculates this score based on several factors including excess inventory percentage, in-stock inventory percentage, stranded inventory percentage, and sell-through rate (units sold and shipped over the past 90 days divided by the average number of units available at fulfillment centers).
Efficient inventory management ensures an effective cash flow, decreases holding costs, improves customer satisfaction, and ultimately, enhances profitability.
How to optimize your IPI:
- Regular Review of the Inventory Dashboard: Amazon provides an Inventory Dashboard that gives an overview of your inventory health. Regularly monitoring this dashboard will help you identify potential issues that may affect your IPI score, such as excess stock or slow-moving items.
- Managing Excess or Slow-moving Stock: Every item in your inventory costs money to store, and slow-selling products will erode profitability. Amazon flags items stored in fulfillment centers for more than 365 days as “aged inventory”. To prevent buildup, consider strategies such as price reductions, running promotions, or even removing the product from your inventory.
- Maintaining Stock of Best-selling Items: While it’s important to reduce slow-moving items, it’s equally vital to keep your best-selling products in stock. Stock-outs not only lead to lost sales but also reduce customer satisfaction and can negatively affect your IPI score. Forecast demand accurately to ensure optimal stocking levels of best-sellers.
- Regular Inventory Reconciliation: Inventory discrepancies may occur due to factors such as misplaced, damaged, or lost items, or due to returns. Regularly reconciling your inventory helps maintain accurate stock levels, which in turn, positively impacts your IPI score.
- Accurate Record Keeping: Maintaining accurate records of your inventory contributes to an efficient supply chain, which Amazon rewards with a higher IPI score. Accurate records allow for better forecasting, prevent overselling, and assist in identifying trends and patterns that can better inform business decisions.
Leveraging Amazon's Fulfillment Options
The fulfillment options available on Amazon are FBA, FBM, both FBA and FBA, onsite, or Multi-channel fulfillment.
Fulfillment by Amazon (FBA): Fulfillment by Amazon allows sellers to entrust their entire logistics process to Amazon. Under FBA, sellers store their products in Amazon’s fulfillment centers, where Amazon takes care of storage, packing, shipping, customer service, and even returns. This allows businesses to tap into Amazon’s world-class logistics network, freeing up their time to focus more on business growth.
FBA products are eligible for Amazon Prime, which can significantly boost product visibility and attractiveness on the platform due to faster delivery times. As a result, FBA can be a highly valuable option for sellers aiming to scale their business quickly, without incurring the hassle and cost of managing a comprehensive delivery and customer service system.
Fulfillment by Merchant (FBM): On the opposite end of the spectrum is Fulfillment by Merchant, in which sellers handle storage, packing, shipping, and customer service. This method offers more control over the inventory, packaging, and shipping processes but comes with the responsibility of fulfilling orders promptly and maintaining high service standards.
FBM can be particularly beneficial for sellers with products that have lower turnover rates or unique shipping requirements that might not be optimally handled under Amazon’s standardized FBA system. FBM also allows sellers to leverage their existing logistics infrastructure, or to use other fulfillment options like third-party logistics providers.
Balancing FBA and FBM: While FBA and FBM each have their advantages, often the best strategy involves using a mix of both. This balance allows sellers to optimize their fulfillment strategy based on product type, seasonality, and shipping costs. For example, high-volume, lightweight items might be best suited to FBA due to Amazon’s competitive shipping rates and access to Prime customers. Conversely, slow-moving, bulky, or highly specialized items might be more cost-effective and manageable under FBM.
FBA Onsite: Fulfillment by Amazon Onsite, is an extension of Amazon’s FBA program that offers sellers greater control and efficiency in managing their inventory and order fulfillment. Unlike traditional FBA, where sellers store their products in Amazon warehouses, FBA Onsite allows sellers to store their inventory at their location(s). Amazon handles the pickup and delivery of inventory, as well as order fulfillment and customer service, but products are not stored in Amazon fulfillment centers. This model reduces storage fees, and inbound shipping costs, and simplifies inventory management for sellers. Additionally, FBA Onsite provides access to Amazon Prime and other services, making it an attractive option for sellers looking to streamline their operations and improve customer service.
Multi-Channel Fulfilment: MCF, or Multi-Channel Fulfillment, is a service offered by Amazon as part of its Fulfillment by Amazon (FBA) program. With MCF, sellers can send their inventory directly to an Amazon fulfillment center. When customers make purchases on the seller’s website or other third-party sales channels, Amazon receives the orders and handles the picking, packing, and shipping directly to the customers. This means that sellers can fulfill orders from multiple sales channels using their existing FBA inventory, streamlining the fulfillment process and ensuring timely delivery to customers regardless of where they make their purchases.
Demand Forecasting and Stock Optimization
Demand forecasting is the process of predicting future sales outcomes based on historical data. Other forecasting metrics include average inventory, market research, trend projection, econometrics, regression analysis, time series analysis, competitor behavior, safety stock, past sales, seasonality, and consumer trends. By predicting demand accurately, sellers can optimize their stock levels, ensuring they can meet customer demand promptly without being burdened by overstocking.
Implementing sophisticated tools and techniques can significantly enhance the accuracy of your forecasting. Time-series analysis, machine learning models, and inventory management software are some solutions that can help create accurate demand forecasts. Additionally, adopting a just-in-time (JIT) inventory approach can bring substantial benefits. Under JIT, stock is replenished only as it’s needed, reducing holding costs and minimizing the risk of stock obsolescence.
The Problem With Stockouts and Overstocking
Addressing the issues of stockouts and overstocking is crucial for Inventory management. Stockouts can result in lost sales and diminish customer satisfaction, while overstock consumes unnecessary capital and space. To mitigate these, it’s effective to gather precise data, employ inventory management systems, calculate reorder points, align with consumer demand, and collaborate with logistics experts.
A robust replenishment strategy, triggered by specific stock levels or lead times, along with an inventory health dashboard for real-time insights, supports proactive decision-making. Regular review and adjustment of inventory practices help balance stock levels, ensuring efficiency and customer satisfaction.
Harnessing Data Analytics for Inventory Management
Analyzing inventory data will uncover trends, identify inefficiencies, and highlight opportunities to optimize stock levels. Key metrics to monitor include sales velocity (the rate at which inventory sells), turnover rate (the number of times inventory is sold or used in a specific period), and sell-through rate (percentage of units sold versus the number received).
Inventory management software that integrates with your Amazon account can automate the process of collecting and analyzing these data points. This can lead to more accurate demand forecasts, data-driven decisions, and opportunities for inventory optimization.
Continuous Improvement and Innovation
To stay competitive, sellers on and off Amazon need a mindset of continuous improvement and adaptability.
- Regularly assess your inventory management processes and seek feedback from your team and customers.
- Stay informed about industry trends, advancements in technology, and new methodologies in inventory management.
- By fostering a culture of innovation and flexibility, you can continuously refine your strategies and respond effectively to market changes.
Remember, there is no one-size-fits-all solution to inventory management. Continuously evaluate your strategies, stay open to innovation, and remain adaptable to the ever-changing dynamics of the Amazon marketplace. With the right approach and tools, you can transform your inventory management into a powerful driver of success in your Amazon enterprise.
In conclusion, effective inventory management is crucial for any enterprise seller on Amazon. By optimizing their Inventory Performance Index (IPI) score, leveraging Amazon’s fulfillment options, accurately forecasting demand, and utilizing data analytics, sellers can achieve efficient inventory management and improved sales performance.
Reducing Stockouts and Overstock
Sellers need to strike a balance between having enough stock to meet customer demand and not having excess stock sitting idly in the warehouse. This balance comes with experience as it takes time to understand one’s customer base, but it is pivotal to successful inventory management. Overstock will tie up capital and lead to storage issues, while stockouts will result in lost sales and dissatisfied customers. Therefore, measures to minimize both situations are vital.
How to Prevent Stockouts
To prevent stockouts, focus on improving inventory forecasting, keeping accurate inventory records, and enhancing supply chain management. Focusing on these elements of inventory management will ensure product availability, maintain sales, improve customer satisfaction, and protect the brand’s reputation.
Sellers should set up and monitor reorder points, which is the specific stock level at which a new order should be placed to replenish stock before it runs out. Sellers need to calculate these reorder points accurately, considering factors such as lead time, safety stock, and the average demand for each product. This will ensure proficient inventory management.
Predictive analytics tools using machine learning and AI can analyze historical sales data and forecast when stock levels are projected to fall below the reorder points. This allows sellers to place timely orders to restock, thereby avoiding stockouts.
How to Avoid Overstocking
Avoiding overstock necessitates a deep understanding of your products’ sales velocity, meaning how quickly items sell within a particular timeframe. Low-velocity items may not need to be heavily stocked, especially if they’re not seasonal or if the demand is not high.
8 tips to avoid overstocking:
- Inventory Management Software: This is your digital assistant for keeping track of everything from sales to stock levels in real-time. It’s a game-changer for making informed decisions quickly and avoiding the dreaded overstock.
- Get Smart with Forecasting: Leverage your sales history to predict future trends. This isn’t just about looking at numbers; it’s about understanding how seasons, trends, and consumer behaviors can impact what you sell.
- Know Your Demand: Understanding demand is more than knowing your bestsellers; it’s about recognizing how different factors can change what your customers want.
- Keep Your Inventory Info Spot-On: Regular checks and balances ensure your stock data is accurate. This way, you’re never caught off guard by sudden overorders or shortages.
- Nail Your Reorder Points: It’s all about timing. Calculating the perfect moment to reorder can save you from both shortages and surplus stock, keeping that inventory balance just right.
- Centralize Your Data: A single source of truth for all your inventory and sales data makes decision-making simpler and more effective. It’s like having a bird’s eye view of your entire operation.
- Set Clear Inventory Levels: Define the minimum and maximum levels for your products. This framework helps guide your purchasing decisions and ensures you’re always within the sweet spot of stock levels.
- Keep an Eye on Market Trends: Staying ahead of market trends and adapting your inventory accordingly means you’re always ready to meet your customers’ evolving needs.
