As an Amazon seller, understanding the Fulfillment by Amazon (FBA) storage limit can play a pivotal role in managing inventory efficiently. These limits, also known as FBA capacity limits, dictate the amount of inventory a seller can send to and store at Amazon's fulfillment centers on a monthly basis. Effective since March 1st, 2023, Amazon has streamlined this system by removing weekly restock limits and quarterly storage volume limits, replacing them with a single monthly capacity limit.

Awareness of these storage limits enables sellers to optimize their inventory, plan procurement and manufacturing processes, and mitigate unnecessary costs. Managing FBA storage limits can be done through Seller Central, which provides relevant information and tools to make informed decisions. It's essential to keep track of these storage limits and make adjustments accordingly, as exceeding them may result in additional fees or impacts on marketplace selling.

Understanding Amazon FBA Storage Limits

The Concept of FBA Storage Limits

Amazon FBA storage limits, also known as FBA capacity limits, are monthly limits set by Amazon to regulate the amount of inventory sellers can send to and store at Amazon's fulfillment centers. These limits were introduced on March 1st, 2023, replacing the previously implemented weekly restock limits and quarterly storage volume limits. The purpose of implementing a single monthly limit is to help sellers manage inventory more efficiently and with better control.

Units and Cubic Feet

FBA capacity limits are generally measured in two ways:

• Units - The number of individual items within a shipment.
• Cubic feet - The space occupied by the items in the fulfillment center, which is influenced by the size and volume of the products.

Sellers with excess inventory face higher storage fees and even penalty fees for long-term storage (six months or more). It is, therefore, essential for sellers to track their inventory levels to remain within Amazon's capacity limits and minimize storage fees.

Fulfillment Center Capacity

Amazon's fulfillment center capacity refers to the amount of storage space available at each fulfillment center for hosting seller products. The available capacity affects FBA capacity limits, as Amazon aims to allocate warehouse space efficiently to the most successful sellers while minimizing the risk of overstocked or stranded inventory.

Sellers should be mindful of their FBA capacity limits and consider the fulfillment center capacity when planning inventory procurement, manufacturing, and shipping schedules. This will enable sellers to optimize their inventory levels, avoid high storage fees, and ultimately increase overall profits.

Inventory Management in Amazon FBA

Inventory Performance Index

Inventory Performance Index (IPI) is a metric that Amazon uses to measure how well sellers are managing their FBA inventory. A higher IPI score indicates better inventory management and may result in additional benefits such as increased storage limits and reduced fees. Sellers are advised to monitor their IPI score regularly to ensure that their inventory is optimized for better sales performance.

Restock Limits and Reservation Fees

Amazon FBA sets monthly restock limits that determine the amount of inventory sellers can send and store in Amazon fulfillment centers. These limits take into account factors such as sales velocity, historical sales data, and available storage capacity. While these limits help ensure efficient inventory management, exceeding these limits may result in reservation fees for unprocessed inventory. Sellers should adhere to their restock limits to avoid incurring additional fees and ensure timely inventory management.

In-Stock Rate and Sell-Through Rate

In-Stock Rate (ISR) represents the percentage of time an item is available for sale at Amazon fulfillment centers. A higher ISR indicates better inventory management and may lead to improved sales. On the other hand, Sell-Through Rate (STR) measures the speed at which your inventory is sold over a specific period. A higher STR suggests better product demand and performance. Monitoring these metrics can help sellers identify trends and optimize inventory management strategies to maximize sales and minimize stockouts.

Excess and Stranded Inventory

Excess inventory refers to items that have not sold within a certain time frame and may take up valuable storage space, leading to increased storage costs. Sellers should actively identify and address excess inventory to maintain efficient inventory levels and reduce costs. On the other hand, stranded inventory refers to items that are not available for sale due to issues such as listing errors or missing information. Identifying and resolving stranded inventory issues can help sellers improve their inventory management and maintain a healthy IPI score.

Using Seller Central for Storage Limit Management

Understanding the FBA Dashboard

The Fulfillment by Amazon (FBA) Dashboard within Seller Central is a one-stop location for FBA sellers to manage their inventory, storage limits, and more. It provides an overview of each seller's storage limits, as well as other relevant data such as available capacity and inventory performance. By regularly accessing this dashboard, sellers can stay informed about their storage utilization and make informed decisions regarding their inventory management strategies.

Navigating the Capacity Monitor

In Seller Central, the Capacity Monitor is a crucial tool for Amazon FBA sellers looking to manage their storage limits effectively. It displays the available capacity for each storage type: standard, oversized, apparel, and more. This resource also provides details on each seller's current inventory levels and their progress toward their storage limit. Using the Capacity Monitor, sellers can make better decisions about restocking and managing their products within Amazon's FBA network.

Utilizing the Storage Limit Manager

The Storage Limit Manager is another useful tool within Seller Central that helps Amazon FBA sellers optimize their storage limits. This feature offers insights into how to increase storage capacity, such as improving inventory performance and meeting other Amazon performance metrics. By leveraging the Storage Limit Manager, sellers can identify areas for improvement and implement strategies to maximize their storage capacity in FBA warehouses.

In summary, using Seller Central tools like the FBA Dashboard, Capacity Monitor, and Storage Limit Manager can significantly aid Amazon FBA sellers in managing their storage limits effectively. It is crucial for sellers to stay informed about their inventory levels and capacity limits to make strategic decisions that help optimize their business on the Amazon platform.

Amazon FBA Capacity Limits

Establishing Capacity Management System

Amazon has introduced a new FBA capacity management system designed to offer sellers more predictability and control. The company has replaced the previous weekly restock limits and quarterly storage volume limits with a single, month-long FBA capacity limit, effective from March 1, 2023. This innovative capacity management system aims to simplify the process for sellers while providing better inventory control and storage limit estimation.

Estimating Maximum Capacity

Estimating the maximum capacity in Amazon's FBA capacity limits is based on a seller's Inventory Performance Index (IPI) score. Sellers with a higher IPI score will have increased storage capacity, whereas those with low IPI scores may experience reduced capacity. The IPI score serves as a performance indicator, reflecting how efficiently a seller manages their inventory within Amazon's fulfillment centers.

To optimize the utilization of FBA capacity limits, sellers should focus on the following strategies:

• Maintain a healthy IPI score: Improve inventory management by monitoring inventory levels and sales velocity.
• Replenish inventory efficiently: Strategically plan restocks to prevent stockouts and minimize excess or aged inventory.
• Monitor capacity usage: Keep track of the storage utilization to take advantage of the allotted storage capacity.

Overview of the Pilot Program

Amazon rolled out a pilot program to test the new FBA capacity limits before implementing them widely. The pilot program aimed to gather feedback from a select group of sellers to refine the system and ensure a smooth transition. This input has influenced adjustments to the FBA capacity limits, resulting in a more streamlined and effective inventory management process.

The introduction of Amazon's FBA capacity limits offers a more predictable and controlled storage management system for sellers. Implemented based on sellers' IPI scores, efficient inventory management is encouraged, resulting in a more productive use of storage space in Amazon's fulfillment centers.

Cost Implications of Amazon FBA Storage Limits

Assessing Storage Fees

Amazon FBA storage limits have an impact on the overall costs tied to managing your FBA inventory. One fundamental cost to consider is the storage fees. Amazon charges storage fees based on the size and duration of your inventory stored at their fulfillment centers. These fees are charged on a monthly basis and are calculated using the daily average volume (cubic feet) of your stored inventory. It's essential to understand the storage fees to better manage your inventory costs.

Impact of Overage Fees

Overage fees are an additional expense to keep in mind for FBA sellers who exceed their Amazon storage limits. When you store more inventory than your assigned limit, Amazon charges you an overage fee for any excess inventory. This fee is calculated daily, applying to the inventory exceeding your limits. Overage fees can add up quickly, affecting your bottom line and profitability. Monitoring your storage usage and ensuring you stay within your capacity limits can help you avoid these extra costs.

Evaluating Reservation Fee Costs

Amazon also offers a pilot program for FBA sellers who have reached their storage limits. This program, called Amazon Marketplace Storage Reservation, allows sellers to bid for more storage space beyond their assigned limits. Sellers incur reservation fee costs only if their inventory doesn't move quickly. It's essential to evaluate these reservation fee costs and weigh them against the potential benefits of increased storage capacity. Taking this into consideration will allow you to make informed decisions about managing your FBA inventory and associated expenses.

Marketplace Selling and Amazon FBA

Professional vs. Individual Selling Accounts

Amazon offers two types of selling accounts for sellers: Professional and Individual Selling Accounts. Professional sellers can list an unlimited number of items for a monthly subscription fee, while Individual selling accounts have no monthly fee but are charged a per-item fee for each item sold. Professional sellers usually benefit from lower per-item fees and access to additional selling tools and resources.

Individual sellers, on the other hand, typically start this way to test the waters and familiarize themselves with the workings of the Amazon marketplace before deciding to upgrade to a Professional Selling Account.

Sales Performance in Amazon Marketplace

Sales performance plays a crucial role in the success of Amazon sellers. Maintaining healthy metrics is essential for ensuring visibility, winning the Buy Box, and enjoying other benefits that come with having a good sales performance. Some key performance indicators (KPIs) that Amazon evaluates include:

• Order Defect Rate (ODR): The percentage of orders with negative feedback, A-to-Z Guarantee claims, or credit card chargebacks.
• Perfect Order Percentage (POP): The percentage of orders that meet or exceed customer expectations.
• Late Shipment Rate (LSR): The percentage of orders shipped later than the expected ship date.

Meeting or exceeding these KPIs positions sellers to be more competitive in the Amazon marketplace.

Understanding Amazon Warehouse Space

Fulfillment by Amazon (FBA) gives sellers access to Amazon's warehouse space for storing inventory, while Amazon manages the storage, picking, packing, and shipping processes. Amazon FBA has storage limits called FBA capacity limits, which are monthly limits determining how much inventory sellers can send and store at Amazon's fulfillment centers. These constraints, aligned with a seller's Inventory Performance Index (IPI) score, help prevent sellers from overusing or mismanaging Amazon's fulfillment service.

Making the most of the available warehouse space and understanding Amazon's storage limits are crucial for sellers to maintain a smooth-running business on the platform and avoid any penalties or inventory restrictions due to overstocking or underutilizing the allotted storage.
