Understanding whether Fulfillment by Amazon (FBA) or a 3PL is more affordable can help inform how you run your ecommerce business. By examining the cost structures of Amazon FBA vs a 3PL using the real-life situation puts the pros and cons of each in context. This article provides a straightforward cost comparison of both options, breaking down key expenses to help you make an informed decision.

Key Takeaways

  • Amazon FBA offers convenience but comes with various fees, including fulfillment, storage, and additional costs that can be challenging to manage for small businesses, especially in the critical peak holiday season.
  • 3PL providers offer flexible pricing and storage solutions, allowing for better cost management and customization, which can lead to significant savings and reduced operational costs.
  • The choice between Amazon FBA and 3PL depends on business size, control over branding and the customer relationship, international shipping needs, and the specific demands of the marketplace.

Understanding Amazon FBA Costs

Amazon FBA (Fulfillment by Amazon) is a popular choice for many ecommerce businesses, offering a comprehensive suite of services that includes storage, picking, packing, shipping, and even customer service. However, these conveniences come with a variety of fees that can be challenging to predict, particularly for small businesses or those with low-margin products. Understanding the key cost components (separate from the referral fees that are paid regardless of who is fulfilling the order) is essential for making an informed decision.

Fulfillment Fees

Fulfillment fees are one of the primary costs associated with Amazon FBA. These fees are calculated based on the size and weight of each product, with tiered pricing. This means that larger or heavier items will incur higher fees, which can impact your profit margins as they change through the tiers, especially if you’re selling bulky goods. The ability to manage costs effectively is job numero uno for any business owner, so many Sellers use Amazon’s Revenue Calculator to predict their expenses and plan accordingly.

One advantage of Amazon FBA’s fulfillment service is its low level of accessibility that allows even brand new businesses to compete. Outsourcing fulfillment to Amazon allows businesses to concentrate on startup operations, expanding sales channels, and improving customer satisfaction, with the assurance that orders are managed efficiently.

Despite the higher fees in some cases, the potential for quick and efficient shipping costs can be a strong motivator for many ecommerce businesses.

Storage Fees

Storage fees for Amazon FBA are another critical cost to consider. These fees are charged monthly based on the volume of inventory stored at Amazon’s fulfillment centers at the end of each month. The rates can fluctuate significantly, ranging from $0.78 to $4.28 per cubic foot, depending on the size of the product, the seasonal period, and how long the items have been in storage.

And it’s essential to be aware of long-term storage fees, (aka ‘Aged Inventory Surcharges’), which apply to inventory held for over 180 days. These storage fees can range from $0.50 to $6.90 per cubic foot, depending on the age of the inventory.

Additionally, Amazon imposes storage limits and surcharges for aged inventory to encourage timely turnover. For businesses with slow-moving products, these additional charges can add up quickly, making it crucial to manage inventory levels very carefully.

Additional Fees

In addition to basic fulfillment and storage fees, Amazon FBA has several extra costs that can surprise businesses. Examples include removal fees for unsold inventory, disposal fees per unit, and returns processing fees. These additional fees can vary based on the weight and size of the products, as well as the specific services required.

Amazon also imposes charges for necessary unplanned services they perform on a Seller’s behalf, such as labeling items that arrive without the required FNSKUs, distributing inventory across multiple warehouses (placement fees) to ensure high probability of on-time delivery to customers, inbound defect fees, among others.

By being mindful of these potential fees and ensuring that they are only billed for necessary services and storage space, businesses can better control their overall fulfillment costs.

Analyzing 3PL Cost Structure

Third-party logistics (3PL) providers offer an alternative to Amazon FBA, with a different approach to cost structures and services. A primary advantage of 3PL providers is their increased flexibility and control over the supply chain. These providers often offer competitive pricing and flexible terms, which can help businesses manage their fulfillment costs more effectively.

Examining Transparent Pricing, Flexible Storage Fees, and Value-Added Services reveals how 3PLs can benefit your ecommerce business.

Transparent Pricing

One of the significant benefits of working with 3PL providers is their transparent pricing models. Unlike Amazon FBA’s fixed costs, 3PLs typically offer customizable logistics solutions that can be tailored to a business’s specific needs. This flexibility allows businesses to negotiate contracts and optimize costs based on their unique requirements.

Specialized 3PL providers often offer even more transparent and flexible pricing structures, resulting in significant cost savings for businesses that need them.

Flexible Storage Fees

When it comes to storage fees, 3PL providers often have an edge over Amazon FBA due to their flexibility. They can offer personalized services that accommodate varying business sizes and seasonal demands, making it easier for businesses to manage their inventory effectively. 3PL providers can offer lower storage fees that are not punitive like FBA’s, which is particularly beneficial for long-term warehousing. This flexibility can lead to cost savings, especially for businesses with large or slow-moving inventory.

Moreover, similar to FBA, 3PLs utilize advanced technology and analytics to enhance inventory control, which helps in predicting inventory needs and preventing overstocking. This can significantly reduce storage expenses and improve overall cost management.

Offering real-time visibility into stock levels and specialty storage solutions such as climate-controlled storage, and storage for fragile items, 3PLs help businesses maintain optimal inventory levels in their ideal environments without excessive costs.

Value-Added Services

3PL providers also offer numerous value-added services that can enhance the overall efficiency of a business’s supply chain. These services include things like custom packaging, custom inserts such as thank you notes or requests for customer reviews, and supply chain management solutions. These customizable services enable 3PLs to optimize logistics operations and create significant value for businesses.

Additionally, 3PL providers support business scalability by allowing flexibility and adaptability during periods of growth.

Comparing Fulfillment Costs: Amazon FBA vs. 3PL

Having a clear understanding of the cost structures of Amazon FBA and 3PL providers allows for a direct comparison of these two options. The comparison will focus on Order Fulfillment Costs, Inventory Storage Costs, and Hidden Costs, helping you determine which option is more affordable for your business.

Order Fulfillment Costs

When it comes to order fulfillment costs, Amazon FBA offers a cost estimator tool that helps Sellers forecast their expenses based on usage. The predictable nature of the fixed pricing model can benefit small businesses in particular by allowing them to manage costs with some level of certainty. Leveraging Amazon’s vast network of warehouses, businesses can achieve quick and efficient shipping, which is crucial for Prime customer satisfaction.

On the other hand, 3PL providers offer various pricing models, including all-in rates and transactional pricing, to suit different client needs. These flexible pricing structures can be more cost-effective for businesses with fluctuating order volumes, diverse product catalogs, or items with complex fulfillment requirements.

A company handling peak season orders efficiently can easily manage a 15-fold increase in volume using 3PL services, especially when taking advantage of Amazon’s Order Handling Capacity automations. This flexibility enables businesses at any stage to scale operations and fulfillment processes without prohibitive costs, making 3PL a viable option for many types of Sellers.

Inventory Storage Costs

Inventory storage costs can vary significantly between Amazon FBA and 3PL providers. Amazon’s storage fees vary based on inventory volume and time of year, with higher rates during peak seasons. Additionally, an aged inventory surcharge is applied if items are stored for over 180 days, which can wildly impact margins and profitability. Watch out if your products are big and bulky which are penalized and accrue at an even higher rate.

In contrast, 3PL providers often offer more flexible and lower storage fees, particularly beneficial for businesses with large or long-term inventory needs. Advanced analytics and real-time visibility into stock levels allow 3PLs to help businesses manage inventory more efficiently and reduce storage expenses. In addition, the ability to procure more inventory at more favorable prices and not be penalized with aged inventory surcharges can mean a stronger bottom line.

Hidden Costs

Hidden costs can naturally impact the overall affordability of using Amazon FBA. FBA Sellers may face unplanned costs for inventory removal, automatic approval of returns and the resulting processing fees, and other unplanned service fees, which Amazon determines at their discretion and can add up over time. These unexpected fees can make it challenging for businesses to maintain profitability, especially those with lower margins.

In contrast, 3PL providers often offer clearer communication of pricing structures and flexible opt-in operational solutions, helping businesses avoid hidden costs and ensuring they understand potential expenses upfront. Sellers using 3PLs also control their customer service experience and define their own returns policies (within Amazon’s well-known guidelines). This transparency can lead to better cost management and improved profit margins.

Cost Savings Strategies with 3PL Providers

Choosing the right fulfillment partner can lead to substantial cost savings and enhanced profit margins. Fulfillment providers offer several strategies to help businesses reduce operational expenses, including negotiating contracts, optimizing inventory management, and leveraging multi-channel fulfillment.

Implementing these strategies enables businesses to optimize their supply chain, enhance customer satisfaction, and achieve significant cost savings.

Negotiating Contracts

Negotiating 3PL contract terms can help businesses secure better pricing and service standards aligned with their objectives. Regular discussions with your 3PL partner can uncover new cost-saving opportunities and ensure favorable contract terms.

This proactive approach can lead to substantial cost savings and more effective fulfillment services, ultimately enhancing overall profitability.

Optimizing Inventory Management

Effective and flexible inventory management is key to containing costs and growing market share. Outsourcing fulfillment to a 3PL provider allows businesses to streamline the process, reducing operational costs and enhancing efficiency. For example, 3PLs that offer deeper supply chain support can put more of the end-to-end work under one roof, allowing for improved inventory procurement and management. High-quality and efficient fulfillment strategies can drive repeat purchases and increase revenue.

Leveraging Multi-Channel Fulfillment

Amazon’s Multi-Channel Fulfillment (MCF) service uses the FBA network and inventory to fulfill orders from non-Amazon channels. There are several challenges to the MCF program, from fulfillment fees that are 2.5 – 3X higher than FBA, to having lower priority than FBA (Amazon.com) orders, to shared inventory storage limits. There is a solution to the latter problem, but an expensive one. Amazon’s Capacity Manager enables Sellers to essentially bid for extra storage space. you can tell Amazon how much extra space you need and when, and how much you’re willing to pay for it (this “reservation fee” is separate from standard storage fees). So, you can get more space to cover both your FBA and MCF orders, but you’re competing with other Sellers for the space, and you have no idea what the going rate is at any given time. So if you need it, you’re going to have to bid high or it will go to someone else.

3PL capabilities for multi-channel fulfillment are much more flexible and encourage businesses to support and manage operations across various ecommerce platforms, marketplaces, B2B channels, etc., enhancing reach and flexibility. Integrating with multiple sales channels, including custom platforms, allows 3PL providers to maintain high order fulfillment efficiency, (treating all orders as important), and facilitate returns processing. This leads to improved customer satisfaction and better overall business performance, ultimately driving long-term revenue growth.

Impact on Profit Margins

Fulfillment costs (including shipping) are central to determining a business’s operational profit margin. Higher costs can significantly reduce profitability, so choosing the right fulfillment process and strategy is essential.

Both Amazon FBA and 3PL providers offer unique advantages that can impact cost efficiency and revenue growth, depending on the specific needs of the business.

Cost Efficiency

Cost efficiency is a significant factor in maintaining healthy profit margins. Optimizing supply chain processes and ensuring quick and efficient shipping help businesses achieve significant cost savings and improve overall profitability. By way of example, one Cahoot client reported a 30% reduction in fulfillment costs after transitioning to the fulfillment provider, from streamlined shipping expenses.

Revenue Growth

Effective fulfillment strategies can greatly influence revenue growth by enhancing customer satisfaction. A notable case involved a Cahoot client that grew 90% year over year in their first year with the new provider, AND saved 40 labor hours per week. Focusing on quick and efficient shipping drives repeat purchases and fosters long-term revenue growth.

Key Factors Influencing Your Decision

The choice between Amazon FBA and 3PL hinges on a business’s specific needs and objectives. Factors such as Business Size and Order Volume, Brand Control and Customization, and International Shipping Needs all play a unique role in making this decision.

Considering these factors helps businesses select the fulfillment strategy that best aligns with their goals and resources.

Business Size and Order Volume

Higher sales volumes often make Amazon FBA a more appealing choice due to its efficiency in handling large orders. However, 3PL providers offer more tailored solutions for businesses with unique inventory management requirements or seasonal fluctuations in sales.

Considering their specific needs allows businesses to choose the fulfillment center option that best suits their order volume and operational demands.

Brand Control and Customization

Brand control and customization are critical for businesses looking to establish a unique identity and enhance the customer experience. Unlike Amazon FBA, which limits branding options, 3PL providers offer extensive customization capabilities, including branded packaging and personalized unboxing experiences. This control can significantly impact customer relationships and loyalty, with over 50% of online shoppers likely to return due to positive packaging experiences.

Businesses prioritizing brand experience may find choosing a 3PL provider advantageous. 3PLs allow the use of custom packaging, inserts (e.g. handwritten notes, coupons for future purchases), and shipping materials, providing greater control over customer interactions and enhancing the overall brand experience. This emphasis on brand customization not only improves brand recognition but also fosters customer loyalty.

International Shipping Needs

International shipping is essential for businesses looking to expand their reach and serve customers globally. Amazon FBA provides integrated international shipping options, making it easier for Sellers to manage shipments and comply with customs regulations.

However, 3PL providers offer customizable international shipping solutions, (e.g. delivered with duties paid or unpaid, wider carrier selection, etc.), that can provide greater flexibility and might be more cost-effective based on specific shipping needs. Evaluating international shipping requirements helps businesses choose the fulfillment option that best supports their global expansion goals.

Summary

Both Amazon FBA and 3PL providers offer unique advantages and cost structures that can benefit ecommerce businesses in different ways. Amazon FBA provides seamless integration with Amazon’s vast customer base, quick and efficient shipping, and comprehensive (overly customer-centric) customer service. On the other hand, 3PL providers offer flexible pricing, customizable services, and greater control over the supply chain and the customer relationship. By carefully considering factors such as business size, order volume, brand control, and international shipping needs, businesses can make an informed decision that aligns with their goals and resources. Choose the fulfillment strategy that best supports your growth and profitability, and watch your business thrive.
