Amazon's commingled inventory system can be a bit tricky to understand, but essentially, it means that products from different sellers are stored and shipped together in the same warehouse. This can be beneficial for Amazon as it allows them to optimize storage space and reduce costs.

Amazon's commingled inventory system is a key factor in their ability to offer free shipping on many items. By storing products from multiple sellers in the same warehouse, Amazon can consolidate shipments and reduce the cost of shipping.

However, this system can also lead to issues with inventory accuracy and customer satisfaction. For example, if a seller's products are commingled with those of another seller, it can be difficult to track inventory levels and ensure that customers receive the correct products.

Amazon's commingled inventory system is used for a wide range of products, including electronics, clothing, and home goods.

What Is Commingling?

Commingling is storing and selling standardized items without labeling them. This means that it's impossible to tell one seller's products from another seller's products with the same UPC codes.

Amazon commingling fulfillment implies mixing products with the same manufacturer ID from Amazon itself, various third-party sellers, and from brands directly. This is how commingled inventory is handled.

A product's existing UPC is the barcode that already exists on most manufactured products. If a seller chooses this option, their inventory is commingled.

Commingled inventory is all put together in a bin, no matter who the seller of record might be. When an order for Seller A’s unit of inventory arrives, it may be fulfilled by any of the commingled units Amazon has on hand – from any seller.

How It Works

Amazon assigns a generic barcode called an ASIN to each product, which identifies the product itself rather than the seller.

In Amazon's commingled inventory system, identical products from different sellers are mingled together in fulfillment centers.

The ASIN barcode is used to determine which seller's product should be shipped to the customer when an order is placed.

This means that Amazon may ship a product from a different seller than the one the customer purchased if multiple sellers have the same product.

Amazon's system scans the ASIN barcode to ensure the correct product is shipped to the customer.

Reasons for Use

Amazon's commingled inventory system is designed to streamline logistics and improve efficiency. This is achieved by mixing products from different sellers, allowing for faster shipping times.

By sourcing products from the nearest fulfillment center, Amazon can reduce the time and effort needed to sort, label, and store individual seller's items. This results in significant cost savings.

Amazon's commingled inventory system also ensures efficient use of storage space, reducing overall costs for the company. These savings can be passed on to sellers through lower fees.

Using manufacturer barcodes is a key strategy for avoiding commingled inventory on Amazon. This ensures that products are tracked and identified accurately, reducing the risk of being mixed with other sellers' items.

Manufacturer barcodes offer better protection against counterfeit products, maintaining the integrity of your brand and ensuring customer satisfaction.

Counterfeit products can also lead to lost sales opportunities when products are out of stock due to the difficulties in tracking inventory.

Commingled inventory can impact branding and marketing efforts, making it hard for customers to distinguish authentic products from counterfeits.

The system can also affect pricing strategies and customer trust in the brand.

Here are some potential risks of commingled inventory:

Stickerless Benefits for Sellers

Stickerless, commingled inventory simplifies logistics for Amazon sellers by allowing Amazon to manage stock levels more efficiently, which often translates to faster shipping times.

This efficiency is particularly valuable during peak seasons or when dealing with high volumes of orders.

Sellers can save significant amounts of time without having to mark each item with special FBA stickers, reducing the cost and labor needed for additional labeling and fulfillment operations.

Amazon shoppers trust Amazon more than any other seller, with over 95% of customers trusting Amazon Marketplace for the reliability of shipping.

Here are the key benefits of stickerless, commingled inventory:

  • Improved Efficiency: Streamlines the fulfillment process and reduces time spent on labeling and sorting products.
  • Cost Savings: Eliminates the need for additional packaging and labeling materials, saving on operational expenses.
  • Enhanced Customer Experience: Speeds up order processing and delivery times, leading to higher customer satisfaction.
  • Flexibility in Storage: Products can be stored more efficiently without the need for designated spaces based on individual seller labels.

Impact on FBA Sellers

As an FBA seller, you're likely aware of the risks associated with commingled inventory. Counterfeit products can easily slip into your inventory, damaging your brand's credibility and potentially leading to an account suspension if customers receive inauthentic items.

This can be particularly concerning, as customers may not be able to distinguish your authentic products from counterfeits, affecting your branding and marketing efforts.

Commingled inventory also makes it challenging to track inventory, leading to difficulties in maintaining accurate stock levels. This can result in lost sales opportunities when products are out of stock.

In addition to these risks, commingled inventory can also affect pricing strategies and customer trust in your brand.

Here are some real-world examples of the risks associated with commingled inventory:

  1. Counterfeit games were sent to the FC, and my client’s units purchased from the manufacturer were fulfilled with fakes.
  2. Off-brand fakes were sold in place of name-brand items. These off-brand fakes were a product that plug in, but did not have UL certification. At least two units caught on fire, resulting in a safety suspension for my client.
  3. Tubes of lotion that do not include safety seals were fulfilled from another seller’s inventory. These lotions were not shrink-wrapped, polybagged or otherwise prepped. They leaked everywhere, resulting in complaints for my client.
  4. Shoes that were likely counterfeit (poor stitching) and sometimes had signs of wear were fulfilled in place of my client’s legitimate inventory.
  5. Chinese sellers flooded a clothing listing with fakes, where decals peeled off easily. This resulted in ASIN suspensions for my client.

These risks highlight the importance of maintaining control over your inventory and taking steps to prevent counterfeit products from entering the supply chain.

Pros and Cons

Amazon commingled inventory is a popular option for sellers, but it's essential to weigh its pros and cons before deciding whether it's right for you.

Commingled inventory can save significant amounts of time and money for sellers, eliminating the need for additional labeling and fulfillment operations.

Amazon's expansion across the US, with 140 warehouses built or planned, means that commingled inventory can streamline processes and ensure quick delivery to customers.

More than 95% of customers trust Amazon Marketplace for the reliability of shipping, making it an attractive option for sellers.

However, commingling can deprive sellers of control over their inventory, leaving them vulnerable to counterfeit products being mixed with their goods.

If counterfeit products are sold to customers, it can lead to numerous product returns and negative reviews, badly impacting both the seller's and product's ratings.

Sellers are also at risk of getting flagged for counterfeiting.

Here are some key benefits and drawbacks of commingled inventory to consider:

While commingled inventory can be a double-edged sword, its operational efficiencies can be worth managing the risks for many sellers.

As an FBA seller, it's crucial to monitor your inventory closely. This is vital for safeguarding your business and maintaining customer trust.

The risk of counterfeit products is one of the biggest concerns for FBA sellers with commingled inventory. This can damage sellers who have worked hard to build a reputable brand.

If a customer receives a counterfeit product, they may leave a negative review or even file a complaint with Amazon. This can result in account suspensions or bans.

To mitigate this risk, consider enrolling in Amazon's Brand Registry Program or using manufacturer barcodes for better tracking and protection against counterfeit goods.

Difficulty in Tracking

Tracking inventory can be a real challenge with commingled inventory. Products from different sellers are mixed, making it difficult to monitor stock levels and account for discrepancies.

Commingled inventory can lead to inaccuracies, making it harder to track individual items. This is especially true for FBA sellers, who may struggle to manage their own inventory and fulfill customer orders promptly.

Receiving counterfeit products can further complicate tracking inventory accurately. Ensuring that every item is genuine requires stricter vigilance and meticulous record-keeping.

Overselling can occur when a seller sells more products than they have in stock, resulting in canceled orders, negative reviews, and potential account suspensions.

Impact on Branding

Commingled inventory can harm your branding and marketing efforts, damaging your brand's reputation with counterfeit products entering the supply chain.

Difficulty in tracking inventory makes it challenging to maintain quality control, which is crucial for safeguarding your brand image.

To protect your brand, consider using Manufacturer Barcodes or enrolling in Amazon's Brand Registry Program, which can help you maintain control over your inventory.

Commingled inventory can also make it difficult to differentiate your products from others and stand out to customers, as products from different sellers are mixed.

This can make it challenging to track the success of marketing efforts, as it may be hard to determine which sales came from your specific products, potentially leading to lost sales opportunities.

Maintaining accurate stock levels is also a challenge, potentially resulting in lost sales opportunities when products are out of stock, which can further damage your brand's reputation.

Avoiding Commingling

Avoiding commingling is crucial to maintaining control over your products and preventing issues with customers and Amazon.

Commingling can lead to counterfeit goods being sold as legitimate products, as seen in Example 2, where a client's units were fulfilled with fakes, resulting in a safety suspension.

To avoid commingling, you can store your inventory separately from other sellers' goods. This way, you can ensure that your products are not mixed with others and that customers receive the correct items.

Amazon's practice of commingling can also result in off-brand fakes being sold in place of name-brand items, as demonstrated in Example 2, where off-brand fakes were sold in place of name-brand items, leading to safety suspensions.

Here are some potential issues that can arise from commingling:

  1. Counterfeit goods being sold as legitimate products
  2. Off-brand fakes being sold in place of name-brand items
  3. Products being fulfilled with fakes or damaged items
  4. Customers receiving the wrong products
  5. High return rates for poor-quality items

Amazon's commingling practice is also deceptive, as noted by UB legal scholar Tanya Monestier, who argues that Amazon should no longer be permitted to get away with this practice.

Alternatives to Commingling

Non-commingled FBA inventory is a viable alternative to commingling, especially for sellers who sell highly fraud-prone goods. This approach allows for more control over inventory and can be more cost-effective.

If you're confident in your fulfillment capabilities, non-commingled FBA inventory might be the way to go. You can save time and money by opting for this method.

However, for many sellers, the time and money saved by going stickerless is a strong incentive for commingling. Commingling can indeed grease the wheels for getting orders fulfilled quickly, which Amazon and its customers appreciate.

UB legal scholar Tanya Monestier says Amazon's commingling of goods is deceptive and should stop.

Amazon's practice of commingling means they store goods from different sellers together and sell them interchangeably.

This practice is problematic because some goods are real, some are fake, some are junk, and some are even dangerous.

You might not know what you're getting when you order something on Amazon, as the actual goods you receive may be from a shady third-party seller.

Amazon's pattern of behavior is not new, as Monestier has previously examined their liability in contracts for defective goods.

Amazon tries to avoid liability for goods sold on their platform by claiming they don't hold title to third-party seller goods.

This is a "shell game" where Amazon hides from its liability, according to Monestier.

Monestier argues that Amazon should no longer be allowed to get away with this practice, as it's deceptive and plain simple.

She believes the law should not countenance such a practice and that Amazon should be held accountable for the goods they sell.
