How to Seamlessly Transition from a 1P Vendor to a 3P Seller on Amazon

For years, selling wholesale to Amazon via Vendor Central (1P) was the go-to model for many brands. But structural changes at Amazon, including vendor terminations, limited support from Vendor Managers, and unclear cost structures, have prompted a growing shift. More brands are making the leap to Amazon Seller Central (3P), where they can sell directly to customers and regain control over pricing, inventory, and growth strategy.

This transition, while empowering, requires a thoughtful shift in operations, technology, and team structure. This guide breaks down the key components of a smooth, strategic transition.
‍

Why Make the Switch from 1P to 3P?

Brands often pursue 3P selling for one or more of the following reasons:

• Higher Profit Margins: 3P sellers avoid wholesale pricing and gain direct control over retail pricing, often resulting in stronger margins.
  
  
• Greater Control: From product content to inventory management and marketing, 3P sellers can manage their entire channel end-to-end.
  
  
• Faster Execution: Unlike Vendor Central, which often requires support tickets or long approval cycles, Seller Central allows immediate listing changes and pricing updates.

In short, the 3P model enables agility, if you’re ready for the operational demands that come with it.

Your Transition Roadmap

1. Understand the Structural Shift

Moving from 1P to 3P means changing your relationship with Amazon, from supplier to seller. As a Vendor Central participant, Amazon owns the customer relationship. On Seller Central, you do.

Here’s what that means:

The upside of 3p: full autonomy. The challenge? Full responsibility.

2. Choose a Fulfillment Strategy

Rethinking logistics is one of the most important and complex steps in the transition to 3P.

• Fulfilled by Amazon (FBA)

This is often the smoothest path for former 1P vendors. You still send inventory to Amazon’s warehouses, and they handle storage, shipping, customer service, and returns. You also retain the Prime badge, which boosts conversion rates. 

However, FBA isn’t ideal for every product, especially low-margin SKUs. Be sure to use Amazon’s FBA calculator and tax tools to evaluate profitability.

• Fulfilled by Merchant (FBM)

This gives you full control over fulfillment through your own warehouse or a third-party logistics provider (3PL). This approach offers more flexibility, but it also puts the responsibility for shipping speed and customer service on your shoulders.

• Seller Fulfilled Prime (SFP) 

This is a hybrid option that allows sellers to offer Prime delivery speeds while fulfilling orders themselves. Enrollment is currently closed, but sellers can join the waitlist to be notified when it reopens.

3. Build Your Internal Operations

Transitioning to 3P isn’t just about switching platforms, it requires reworking how your business runs day to day.

• Inventory Management

In 1P, Amazon handles restocking by placing purchase orders based on its own demand forecasts, but you’re still expected to have inventory ready to ship. 

In 3P, you’re fully responsible for monitoring stock levels, forecasting demand, and replenishing inventory proactively. To avoid stockouts or overstocking, it’s essential to implement systems that support inventory planning.

• Cash Flow Differences

In 1P, Amazon pays you in bulk on fixed terms (like 30 or 60 days). With 3P, you only get paid after each order ships, leading to more variable cash flow and requiring a different working capital strategy.

• Order Management

Depending on the fulfillment method, sellers must handle order intake and decide where and how to fulfill them. Using automation tools for tasks like routing and tracking helps reduce errors and scale efficiently.
‍

4. Protect Your Listings

3P gives you complete control over your listings, but with that comes responsibility.

• Enroll in Amazon Brand Registry for IP protection, access to A+ Content, Brand Stores, and reporting tools.
  
  
• Use category-specific templates to include all required product details based on your category’s specific listing standards.
  
  
• Fix listing errors promptly to avoid listing suppression that can kill your momentum.
  
  
• Continuously optimize titles, bullets, backend search terms, and images. Testing is faster and easier on Seller Central—take advantage of it.

Seller Central lets you move fast, so use that speed to your advantage.

5. Maintain Pricing Control

With control comes risk. While you can now set your own prices, Amazon may suppress your Buy Box eligibility if your prices are uncompetitive.

Maintain price parity with external resellers and stay within Amazon’s pricing thresholds to avoid ASIN suppression. Review the Marketplace Fair Pricing Policy regularly and use automated repricers if needed.
‍

6. Strengthen Your Team with the Right External Experts

Building an in-house Amazon team from scratch isn’t always practical, especially during a high-stakes transition from 1P to 3P. For many brands, outsourcing to experienced partners is the fastest, most efficient way to navigate the shift.

Here’s why:

• Agencies bring deep expertise and proven systems. They know how to move quickly and avoid common pitfalls.
  
  
• You gain speed without the learning curve. Outsourced teams can help you launch faster while your internal team ramps up.
  
  
• It’s scalable and flexible. You can start with a lean internal team and expand as needed, relying on external experts to fill technical or operational gaps.
  
  
• You stay focused on core business. While your agency handles the daily mechanics of Seller Central, your internal team can stay focused on brand, product, and supply chain.

Outsourcing allows you to execute like a seasoned 3P seller without the overhead.

Move with Purpose

Transitioning from Vendor Central to Seller Central isn’t just a platform change, it’s a business model shift. It means trading bulk purchase orders for real-time customer demand, passive oversight for hands-on ownership, and vendor relationships for consumer trust.

When done right, transitioning to 3P gives your brand greater pricing control, faster execution, and full ownership of your Amazon strategy. But it’s not just a quick setup, it requires a long-term plan, the right team, and a solid operational foundation. With clear goals and an efficient approach, this move can become a powerful driver of scalable growth.
