Best Seller Fulfilled Prime 3PL Companies

Welcome to another expert blog by Direct Fulfilment 365! Today, we're investigating ways that Amazon sellers can make the most of order fulfilment to achieve customer satisfaction and boost their profit margins.

Our main focus is the Seller Fulfilled Prime program and which third-party logistics provider might be the best option. But we're getting ahead of ourselves here; before plunging into this subject, it's important to provide some context and background...

The Amazon Phenomenon

If you run an ecommerce business, it's likely that you've either used Amazon or you're considering it at some point in the future. After all, why would you risk missing out on a market worth £26 billion? That figure, by the way, is for UK sales back in 2023 and has probably risen significantly since then!

With a market share of around 30%, Amazon can boast that around 90% of UK online shoppers have bought from its platform at some point. At least 40% of these have access to Prime, making them a perfect customer base. fba prep services

As an Amazon seller, you have three options when it comes to order fulfilment, and it's important to understand the difference between these before we move on. If you already know all about this, you're welcome to skip ahead! However, at Direct Fulfilment 365, we like to make sure everyone is on the same page and has access to all the support and information they might need.

Check out this brief description of each program:

Fulfilment By Amazon (FBA)

FBA is a hands-off solution for sellers who want to streamline their operations and let Amazon take care of the heavy lifting. With FBA, you send your inventory to Amazon’s fulfilment centres, and they handle the rest - storage, picking, packing, and shipping.

When a customer places an order, Amazon swiftly processes it and ensures it arrives at their doorstep within the timescales specified by the strict Prime conditions. They also take care of customer service and returns on your behalf, which is a huge bonus if you prefer to focus on scaling your business rather than managing logistics.

Have a look at our post "Alternatives to Amazon FBA".

Seller Fulfilled Prime (SFP)

SFP is the perfect middle ground between having control over your fulfilment and enjoying the benefits of Prime. With SFP, you store and ship your products directly from your own warehouse (or through a trusted third-party logistics provider, which is what we're going to investigate in a moment) but still display the coveted Amazon Prime badge on your listings.

To maintain Prime status, you need to meet Amazon’s strict performance standards, including offering next-day delivery and using Amazon-approved carriers. SFP requires a lot of attention to detail, but if done right, it can give you the best of both worlds - control over your operations while keeping Prime customers happy.

Fulfilled By Merchant (FBM)

FBM is the most hands-on approach, giving you complete control over the entire fulfilment process. With FBM, you list your products on Amazon, but you’re responsible for storage, packaging, shipping, and customer service inquiries.

This approach works well for sellers who prefer to manage their inventory and want to avoid Amazon’s FBA fees. However, it requires a solid logistics strategy to ensure that orders are shipped promptly and accurately.

Amazon Prime Specifications

Amazon enforces strict regulations on its SFP members, and those who fail to meet these measures risk losing their Prime badge status, so it's important to make sure you know these and keep on top of things.

Here's a rundown of the rules so you can see what's expected:

Fast And Reliable Delivery (Prime Standard)

To satisfy Amazon’s high expectations, SFP sellers are required to offer next-day delivery for Prime orders placed before the specified cut-off time. It’s also essential to maintain a 99% on-time dispatch rate. This means that orders must be processed and dispatched promptly to ensure they arrive on time. Prime customers are accustomed to speedy delivery, and any failure to meet this promise can result in the removal of your Prime eligibility.

Same-Day Order Processing

Orders must be picked, packed, and shipped the same day if they are placed before your set cut-off time. SFP sellers are expected to use Amazon-approved carriers capable of meeting Prime-level delivery times. Since speed and efficiency are non-negotiable, having a well-structured workflow or a reliable 3PL partner can make all the difference in maintaining this standard.

Use Of Amazon-Approved Carriers

To ensure consistency, Amazon requires that all SFP orders are shipped using 'Prime-approved carriers'. These carriers must provide tracking information that integrates seamlessly with Amazon’s system. This allows customers to follow their order’s progress in real-time and ensures that deliveries are made on time. Using unauthorised carriers can result in performance issues and possible suspension from the SFP programme.

Low Cancellation Rate

A key requirement for maintaining SFP status is a cancellation rate of less than 0.5%. This means you’ll need to keep your inventory levels accurate and minimise any chance of overselling. High cancellation rates not only harm your Amazon metrics but can also lead to suspension from the programme. Ensuring smooth inventory management and forecasting demand accurately can help you stay within this limit.

High Performance Standards

To stay in the SFP programme, you must maintain a 99% valid tracking rate, ensuring that customers can monitor their orders without issues. Additionally, Amazon expects minimal delivery problems and low return rates. Consistent performance across these metrics is essential to retaining your Prime badge and keeping your customers satisfied.

Compliance With Amazon’s Returns Policy

Although you’re handling fulfilment yourself, SFP sellers are still required to comply with Amazon’s returns and customer service policies. This means that even if you’re shipping orders from your own warehouse, Amazon expects you to maintain the same level of service that customers would experience with FBA. A streamlined and customer-friendly returns process is essential to ensure positive feedback and maintain your Prime status.

How To Qualify For SFP

Sellers must complete a trial period to prove they can meet Amazon’s strict performance standards. During this period, you’ll need to demonstrate consistent on-time Prime shipping, low cancellation rates, and high tracking accuracy. Additionally, Amazon requires the use of its Buy Shipping Services to ensure compliance with delivery speed and tracking requirements, which can be challenging for high-volume sellers. Only after successfully passing this trial can you gain full SFP status.

Why Use A Third-Party Company With SFP?

If you’re an Amazon seller using Seller Fulfilled Prime (SFP), you already know the perks of keeping that Prime badge; higher visibility, increased conversions, and happier customers. But here’s the catch: maintaining Amazon’s strict delivery standards while managing fulfilment in-house can be a real headache. That’s why partnering with a 3PL is a fantastic option, offering the following benefits and advantages...

Stress-Free Fulfilment

Meeting Amazon’s tight delivery windows can be a constant source of stress. Late despatches? Lost packages? It’s enough to keep any seller up at night. A 3PL takes that burden off your shoulders by handling picking, packing, and shipping with precision. They’re experts at meeting Prime deadlines, so you can focus on growing your business rather than worrying about logistics.

Scalability

When your sales spike (especially during peak seasons), keeping up with order volumes can become overwhelming. But with a 3PL, scaling is seamless. They’re built to handle fluctuations in demand, whether it’s Black Friday madness or a sudden surge in orders after a successful product launch. No need to scramble for extra staff or warehouse space as your 3PL has it covered!

SFP-Compliance

Amazon’s SFP programme comes with strict requirements, and missing the mark can mean losing your Prime status. A 3PL ensures that your orders meet Prime delivery standards consistently, helping you maintain your SFP eligibility. Their advanced systems automate order management and optimise delivery routes to keep everything running smoothly.

Multi-Channel Fulfilment

Most 3PLs integrate seamlessly with Amazon and other ecommerce platforms, making it simple to manage orders from multiple sales channels in one place. Whether you’re selling on Amazon, Shopify, eBay, or beyond, a 3PL ensures that fulfilment stays streamlined and efficient.

Save Time, Money, And Hassle

Fulfilment isn’t just about packing boxes. It’s a time-consuming operation that requires staff, space, and expertise. Outsourcing to a 3PL can reduce your operational costs and free up valuable time. Plus, with optimised storage and shipping processes, many 3PLs can even save you money on things like storage fees and shipping costs in the long run.

Better Customer Experience

Happy customers are repeat customers, and fast, accurate delivery plays a huge role in that. A reliable 3PL helps ensure that orders arrive on time and in perfect condition, boosting positive reviews and keeping your customers coming back for more.

Now you're up to speed with all the relevant information, we can continue with our list of exceptional 3PL companies that can help your Amazon business with the SFP program!
