Best 3PL Companies for Amazon Seller Fulfilled Prime in 2025

This article contains our 2025 review of third-party logistics providers associated with Amazon Seller Fulfilled Prime. It remains available as a historical comparison, but provider capabilities, Amazon requirements, ownership structures, and public SFP offerings can change.

For our current research and updated provider shortlist, read our evergreen guide to Seller Fulfilled Prime 3PL providers .

Key Takeaways

• This article reflects the SFP provider market as it was evaluated in 2025. It should not be treated as our current provider shortlist.
• Seller Fulfilled Prime requires more than ordinary Amazon fulfillment or two-day shipping. Sellers must evaluate delivery-promise coverage, same-day execution, weekend operations, tracking, carrier performance, inventory placement, and exception recovery.
• A provider that supported SFP in the past may have changed its service offering, fulfillment network, ownership, or public positioning.
• Our current provider research is available in the updated Seller Fulfilled Prime 3PL guide.
• Sellers preparing for the program should also use the Seller Fulfilled Prime Trial Checklist before selecting a fulfillment partner.

Understanding Amazon Seller Fulfilled Prime

Amazon’s Seller Fulfilled Prime (SFP) program gives businesses a chance to combine the perks of Prime eligibility with the freedom to handle their own shipping. Introduced in the mid-2010s and revamped in 2023, SFP allows Sellers to ship directly from their warehouses or through trusted third-party logistics (3PL) providers, all while showcasing the coveted Prime badge.

This program is an excellent fit for Sellers who can meet Amazon’s tough delivery standards and want to avoid some of the restrictions and costs of Fulfillment by Amazon (FBA). By joining SFP, businesses gain access to millions of loyal Prime members, making it a potentially game-changing opportunity.

How Seller Fulfilled Prime Works

At its core, SFP puts Sellers in charge of the entire fulfillment process—from storage to shipping. This control comes with significant responsibilities, particularly when it comes to delivery speed. Sellers are expected to:

• Meet Amazon’s current one-day and two-day delivery-promise coverage requirements for each applicable product size tier.
• Maintain an on-time delivery rate of at least 93.5%.
• Maintain a valid tracking rate of at least 99%.
• Keep the seller-initiated cancellation rate at or below 0.5%.
• Operate in accordance with Amazon’s current cutoff, weekend, carrier, shipping-template, trial, and program requirements.

Amazon changes SFP requirements over time. For the latest thresholds and operational interpretation, see our current Seller Fulfilled Prime guide and July 2026 SFP speed-requirement update.

Note that page view metrics must be met regardless of whether or not a purchase was made, and this simply means that the estimated delivery date displayed to the customer on your listing page was either 1 or 2 days from today if the view was before 2pm local time, or 1 or 2 days from tomorrow if the view was after 2pm local time. Amazon fully controls page views, it is out of a Seller’s hands.

To meet these expectations profitably, businesses need a well-oiled logistics setup, often involving multiple warehouses and a streamlined shipping process that ensures same-day shipping including carrier origin scans.

Program Requirements and Performance Metrics

Amazon holds SFP participants to high standards. The key metrics that Sellers must consistently meet include:

• On-Time Delivery Rate: At least 93.5% of orders should arrive as promised.
• Valid Tracking Rate: A minimum of 99% of shipments must include accurate tracking numbers using authorized carriers.
• Cancellation Rate: Sellers need to keep pre-fulfillment cancellations below 0.5%. This means no overselling which Amazon considers a bad experience.

Sellers must first prequalify for Seller Fulfilled Prime, then complete a 30-day trial while meeting Amazon’s performance requirements before enrollment. Falling short can lead to warnings, suspension of Prime eligibility, or even removal from the program. If a seller is removed from the program, Amazon allows reenrollment by prequalifying again and starting a new trial, subject to current program policies and trial-attempt limits.

Pros and Cons of Seller Fulfilled Prime

The SFP program offers compelling advantages. Products with the Prime badge often see a boost in visibility and sales, with some businesses reporting significant growth. Sellers also have more control over their inventory and branding, which allows for custom packaging and better alignment with their overall business strategy. Compared with FBA, Seller Fulfilled Prime may reduce some storage-related costs for certain sellers, but the cost tradeoff depends on current Amazon fees, shipping mix, and the seller’s own warehouse network.

However, SFP is not without its challenges. Sellers must invest heavily in logistics infrastructure and technology, especially if they need to cover nationwide delivery. Meeting Amazon’s high standards consistently requires operational excellence, and shipping costs can add up, particularly for larger or expedited orders.

The Role of 3PLs in Supporting SFP

Third-party logistics providers play a critical role in helping businesses succeed with SFP. The right 3PL partner offers the expertise, tools, and infrastructure necessary to meet Amazon’s stringent requirements. Important traits of a reliable 3PL include:

• Cutting-edge technology: Systems that support real-time inventory tracking, multi-warehouse management, and seamless integration with Amazon’s platform.
• Tailored solutions: Customized fulfillment strategies for unique products like oversized items or goods that need special handling.
• Strong shipping partnerships: Relationships with reliable carriers to ensure timely pickups origin scans, and deliveries.
• Deep understanding of Amazon policies: Knowledgeable support to help Sellers stay compliant with SFP requirements.

Provider capabilities should be verified directly before entering a sales process. A company may support Amazon FBM, FBA prep, marketplace fulfillment, or fast delivery without currently supporting the operational requirements of Seller Fulfilled Prime.

Our current review found that the U.S. SFP provider market is narrower than broad Amazon-fulfillment marketing suggests. See the current SFP 3PL shortlist for the providers we presently consider worth evaluating and the caveats attached to each one.

Leading 3PL Companies for Seller Fulfilled Prime

A third-party logistics provider can be transformative for growing ecommerce businesses. These 3PL companies offer a myriad of benefits, including time, energy, and cost savings. Moreover, they provide access to shipping discounts, data analytics, and affordable warehousing solutions, which are indispensable for scaling operations. Ecommerce businesses can focus more on their core activities while ensuring seamless logistics management by tapping into the infrastructure and expertise of a third-party logistics company.

However, with numerous third-party logistics companies in the market, ecommerce businesses often grapple with determining the best fit for their specific needs. 3PL companies provide a range of services such as order fulfillment, inventory management, picking, packing, and shipping, making them an integral part of the ecommerce ecosystem.

A 3PL partnership allows merchants to automate fulfillment processes, enhance efficiency, and deliver a superior customer experience.

Our 2025 SFP Provider Comparison

Selecting the right 3PL provider necessitates a thorough comparison of their capabilities, services, and network reach. The providers in this 2025 comparison were selected based on their ability to meet stringent SFP requirements, provide efficient logistics services, and support business growth.

These top providers leverage a global network of fulfillment centers and supply chains, enabling strategic inventory placement for faster and cost-effective shipping. Having multiple warehouses allows inventory to be stored closer to customers, significantly enhancing delivery speed and reducing shipping costs. In practice, many sellers rely on distributed inventory and efficient ground-shipping coverage to make Seller Fulfilled Prime work economically at scale, although Amazon does not prescribe a specific warehouse-network model. A minimum of 4 locations is required to support SFP, but realistically, 6 locations is what will achieve > 90% of 1 and 2-day shipping using Ground. There will always be some expensive air shipping required to deliver orders on time, but above 6 locations, we start to see diminishing returns on the additional investment in inventory (capital) and inventory management (time).

This section will dig into the unique offerings of each provider, helping you understand which third-party logistics company aligns best with your business needs.

Cahoot

2026 status: Included in our current evergreen SFP provider shortlist.

Cahoot operates a peer-to-peer fulfillment network, specifically designed to meet the rigorous requirements of Amazon Seller Fulfilled Prime. This innovative model allows for efficient sharing of fulfillment resources among partners within the network, optimizing logistics operations and reducing costs. Cahoot ensures compliance with Amazon SFP standards, making it a reliable choice for ecommerce businesses seeking to enhance their fulfillment processes. And, if you already have a trusted 3PL that can support SFP but just doesn’t have enough locations to support it profitably using Ground shipping, Cahoot is the only solution that will allow you to BYO3PL (Bring Your Own 3PL). We can onboard your 3PL seamlessly into the network to fulfill orders in the regions that they can support.

Partnering with Cahoot not only guarantees adherence to Amazon’s stringent criteria but also provides ecommerce merchants with the tools and infrastructure needed to streamline their logistics operations across all sales channels under one roof, so to speak. And flexible features, such as supporting branded packaging, are attractive benefits. This makes Cahoot an attractive option for businesses of just about any size.

Fulfillment by Amazon Is an Alternative to SFP, Not an SFP 3PL

Fulfillment by Amazon and Seller Fulfilled Prime are separate fulfillment models. With FBA, Amazon stores and fulfills the inventory. With SFP, a qualified seller earns the Prime badge while fulfilling eligible orders through its own operation or an outside fulfillment partner.

Sellers may use FBA for some products and SFP for others, but FBA should not be evaluated as a third-party logistics provider for SFP orders. The relevant question is whether a seller should use FBA, SFP, or a SKU-level combination of the two.

Ware2Go

2026 status: Evaluated in our current evergreen SFP provider guide as part of the combined STORD / Ware2Go offering.

Ware2Go offers a flexible and scalable fulfillment network designed to adapt to changing market demands. This agility makes it an excellent choice for ecommerce businesses looking to efficiently manage their logistics operations and meet customer expectations in a dynamic market environment. As a UPS company, Ware2Go emphasizes a UPS-connected network; sellers should confirm carrier flexibility and service-level options directly with Ware2Go during evaluation.

Staci Americas

2026 status: Not included in the current main shortlist because its public positioning did not provide enough modern SFP operating detail for our evaluation criteria.

Staci Americas supports Amazon Seller Fulfilled Prime, providing real-time success insights through an easy-to-use web portal that displays order status, inventory, trend reports, and metrics. This transparency helps ecommerce businesses track their fulfillment performance and make data-driven decisions. Additionally, Staci Americas allows items to be shipped in the Seller’s branded box, enhancing brand visibility and customer experience.

One significant advantage of Staci Americas is the ability to control costs by paying predictable rates for only the space and services used, unlike FBA, which has high storage costs that can rise during the holidays. Their knowledgeable customer service is available whenever needed, offering a level of support that FBA may not provide.

Red Stag Fulfillment

2026 status: Included in our current shortlist for extra-large, bulky, heavy, and specialized-product use cases, subject to validating coverage from its limited warehouse footprint.

Red Stag Fulfillment specializes in shipping heavy items that require special handling, catering primarily to small businesses that ship such products. With two warehouse locations in the US, Red Stag ensures efficient logistics operations for its clients, providing targeted support to American ecommerce businesses.

The company utilizes a cloud-based system and integrates with various ecommerce platforms like Shopify, Amazon, and eBay. Custom integrations are also available via an API, enhancing their service offerings.

This combination of specialized services and advanced technology makes Red Stag Fulfillment a valuable partner for businesses with unique shipping needs. However, only having 2 locations limits RSF’s ability to support Seller Fulfilled Prime. Sellers must either only sell items in the Oversize and Extra Large size tiers in those two regions (regional fulfillment), or they must absorb 1 and 2-day air shipping costs to deliver orders for Standard size products to nationwide customers.

Fulfyld

2026 status: Not included in the current main shortlist because its SFP messaging appeared broad and outdated relative to newer program requirements.

Fulfyld is recognized for its cost-effective ecommerce fulfillment solutions tailored for online merchants. Founded in 2014, Fulfyld has established 8 fulfillment locations in the Southeast United States and integrates with popular platforms like Shopify, Adobe Commerce (formerly Magento), and BigCommerce. Fulfyld meets Amazon Seller Fulfilled Prime (SFP) requirements, however, only having warehouses in the Southeast creates the same problem that Red Stag has. Sellers considering Fulfyld for Amazon Seller Fulfilled Prime should verify current SFP support, network coverage, and shipping economics directly with the provider Regardless of how fast and accurately orders can be shipped, Sellers are either limited to selling large and bulky items in the Southeast only (regional fulfillment), or they must absorb 1 and 2-day air shipping costs to deliver Standard size products to nationwide customers.

In addition to its fulfillment services, Fulfyld offers FBA prep services, including quality assurance checks, barcode labeling, bundling and kitting, and various packaging options like poly-bagging and shrink wrapping. These comprehensive fulfillment service options make Fulfyld a good choice for ecommerce businesses looking for efficiency and cost savings.

ShipMonk

ShipMonk was included in our 2025 review based on the SFP-related information available at the time. Our newer market review did not include ShipMonk in the current shortlist because visible SFP support had been removed from its primary page copy and we could not find enough current public evidence to treat it as an active U.S. SFP provider.

ShipMonk may still be relevant for broader ecommerce fulfillment, Amazon FBM, or other marketplace use cases. Sellers specifically evaluating Seller Fulfilled Prime should confirm current program support directly before assuming that ShipMonk can operate an SFP account.

Key Features to Look for in a 3PL Company

Identifying the right 3PL provider is essential for ecommerce success, as each company offers unique capabilities tailored to business needs. Most outsourced fulfillment partners can help streamline logistics processes enhancing delivery speed and accuracy, but top 3PL companies offer high-quality customer service, advanced software, and transparent pricing, avoiding hidden fees to allow for better management of your logistics costs.

Benefits of Distributed Inventory and Multi-Warehouse Fulfillment

Utilizing multiple distribution centers can significantly lower shipping expenses and enhance delivery speed to customers. Distributing inventory allows businesses to manage risks better, as alternative fulfillment options are available during emergencies. Amazon doesn’t care if an order is shipped and delivered late because of a snowstorm or other type of weather event. So, distributing inventory ensures that orders can be rerouted and fulfilled from the nearest operating distribution center to the customer.

Faster shipment through distributed inventory also leads to higher customer satisfaction and potentially increased sales. Just because Amazon says an order needs to be delivered in 2 days, doesn’t mean that it can’t be delivered in 1-day with Ground shipping. Shipping and delivering early will delight your customers and keep them coming back.

Intuitive Software and Technology

Intuitive software and technology play a vital role within the logistics industry to aid in the successful management of inventory including placement and replenishment. To support Seller Fulfilled Prime using distributed inventory, advanced order routing is required to ensure that all orders are assigned to the cheapest warehouse to fulfill and ship based on real-time rate shopping across all carriers and services. Also, easy-to-use software that natively integrates with leading ecommerce platforms and marketplaces ensures that products are correctly listed across channels and that orders make it into the fulfillment queue so they can be fulfilled accurately and on time, every time. Features like real-time updates to and from sales channels allow businesses to respond promptly to changes in inventory, shipping status, cancellations, and returns, and enable shipping and delivery confirmation messaging which adds to the overall user experience.

Advanced 3PL software makes it easy to create inbound work orders, create discounted parcel shipping labels for the inbounds, or schedule LTL or FTL pickups, container drop-offs, etc. They also provide in-depth management, data analytics, and an easy-to-understand interface for effective order management. Automated inventory management systems help reduce manual errors and enhance operational efficiency, making them indispensable tools for ecommerce businesses.

Strong Partner Network

A robust partner network enhances logistics flexibility and efficiency, enabling 3PLs to provide specialized services and innovative solutions tailored to client requirements. This network allows 3PL providers to offer a wide range of services, from warehousing solutions to freight forwarding (import/export), ensuring comprehensive logistics support.

Cahoot and Staci Americas, for instance, provide tailored solutions for Seller Fulfilled Prime, enhancing support for merchants engaged in Amazon’s fulfillment program. This kind of specialized support is a testament to the value of a strong partner network in meeting the diverse needs of ecommerce businesses.

Competitive Shipping Discounts

3PL companies often negotiate much better shipping rates than an ecommerce business can by aggregating their volume, sometimes including freight volume. This allows them to pass on the benefits of reduced costs to merchants, enhancing overall logistics cost efficiency. These negotiated shipping discounts can improve margins substantially, making these top 3PLs attractive ecommerce partners.

For example, Red Stag Fulfillment offers shipping discounts for various carriers, particularly for oversized items. Cahoot has multiple rate cards across carriers and services to optimize shipping cost for certain sizes going to certain zones at various speeds. So whether you’re shipping small and light, bulky and light, large and heavy, or somewhere in between, there’s a solution for minimizing parcel shipping cost.

It’s worth noting that Cahoot is the only fulfillment solution in this list that allows you to bring your own negotiated carrier accounts. So for example, if you only want to outsource your SFP volume to Cahoot and keep non-SFP volume in-house, you can keep all your shipping postage on your carrier accounts to maintain your rates for all seller-fulfilled orders.

The Role of Customer Service in 3PLs

Customer service is a critical component of any successful logistics partnership. A reputable 3PL provider should adapt to evolving business needs and support growth effectively. High-quality exceptional customer service ensures smooth operations, quick issue resolution, and proactive communication, positively influencing business outcomes.

Automated solutions for returns, offered by many 3PLs, streamline the process and improve customer satisfaction. A well-structured returns process can enhance customer retention and drive brand growth. Pre-vetted recommendations from a 3PL also help ecommerce businesses by providing solutions that have worked for other customers. Modern 3PLs can support newer and more profitable returns business models such as peer-to-peer solutions. Once a return is approved, it’s automatically relisted as an open-box item at a pre-determined discount. You never have to touch the return or pay for the reverse logistics. Everybody either saves money or gets a reward for their participation.

Dedicated Account Management

Having a dedicated account manager stimulates personalized communication and promotes deep understanding of a business’s specific needs. This personalized support is particularly beneficial for high-volume shippers, or those with large or complex product catalogs, or those with specialty project needs such as selling on Good Morning America or The View where advanced planning and rapid execution are required, or for those with specialized needs such as assembly of custom shipping containers for exceptionally fragile products. A dedicated account manager tailors customized services for businesses with unique needs, and Cahoot is well-known to support all of these types of clients and more.

Multi-Channel Support

Multi-channel customer support, (primarily email, live chat, and phone support), is essential for ensuring effective communication and problem resolution between businesses and their 3PL providers. Responsiveness and availability of support across different channels can positively impact customer satisfaction through efficient use of time for issue resolution.

Advanced Fulfillment Solutions

As the ecommerce fulfillment landscape becomes increasingly competitive, innovative fulfillment solutions are essential for delivering positive customer experiences. Advanced fulfillment capabilities such as fast same-day processing and disciplined returns management can improve operational performance for SFP sellers, even though Amazon’s program requirements are ultimately defined by its current policy and performance standards. So make sure your fulfillment partner can accommodate.

Many 3PL providers offer additional services like inventory refurbishment and refreshing damaged retail packaging so units are sellable in new condition, which increases resale opportunities, increases margins, and reduces waste. Implementing these advanced solutions allows ecommerce businesses to stay ahead of the competition.

Automated Order Fulfillment

Automation in order fulfillment operations can streamline processes and improve overall productivity within logistics operations, but more importantly, it reduces fulfillment defects which leads to increased customer satisfaction and loyalty, and reduces return rates which increases profitability and helps to retain what could have been lost revenue.

Strategically locating inventory in multiple warehouses is crucial for achieving 1 and 2-day shipping coverage. For instance, merchants need to strategically locate inventory in four warehouses to ensure 2-day shipping coverage across the continental U.S. Achieving 1-day delivery necessitates positioning inventory in at least 6 fulfillment centers, but as many as 9 may be needed depending on the size and weight of your products.

Real-Time Inventory Management

Real-time inventory tracking enables businesses to more easily manage the supply chain and fulfill customer expectations effectively. Real-time tracking automatically updates stock levels as inventory moves, enhancing visibility and aiding in effective decision-making regarding fulfillment and procurement. Consistent and regular inventory cycle counts ensures that the accurate available quantity is known at all times.

Technology that automatically synchronizes inventory counts and prices across multiple sales channels helps eliminate listing issues that lead to overselling and pre-fulfillment cancellations (which is one of the SFP performance metrics that is closely monitored by Amazon).

Reverse Logistics and Returns Management

3PLs streamline ecommerce returns by offering an easier process, including prepaid return labels and return tracking. Effective customer support for returns includes real-time communication and transparency, enhancing engagement and satisfaction.

Utilizing peer-to-peer returns can lead to significant savings on shipping expenses and a decrease in the time needed for warehouse processing. The immediate restocking of returned products upon request can drastically reduce the processing time typically required at warehouses, and thus, reduces the time to resale. This approach helps businesses manage returns efficiently and improve overall customer experience.

Overcoming Challenges and Ensuring Success

Thriving in the SFP program requires a combination of smart planning and solid execution. Sellers need to position warehouses strategically, ideally near major population hubs, to optimize delivery speeds, (for example, states located in the Northeast, Southeast, North Central, South Central, Northwest, and Southwest regions of the US). Monitoring performance metrics regularly and making real-time changes to promotions to drive eyeballs (page views) is another key to success. This allows sellers to identify and address any issues or dips in metrics before they escalate. Partnering with a capable 3PL provider that offers SFP consulting is also a wise move, as their expertise can help businesses navigate challenges and adapt to Amazon’s unforgiving requirements.
