Amazon’s SPP Migration Deadline: What 3P Sellers Need to Know

The way third-party service providers access and manage seller accounts is changing. Amazon is shifting from individual Selling Partner API (SP-API) connections to a unified Solution Provider Portal (SPP). This means if you rely on an Amazon agency, consultant, or software tool to manage your account, this migration directly impacts your business operations.

Amazon has set a firm migration deadline of April 10, 2025, and 3P sellers must ensure their service providers are registered in the new system to maintain uninterrupted access. Ensuring compliance with Amazon’s latest operational policies is crucial for 3P sellers managing inventory and fulfillment.

What Is Amazon’s Solution Provider Portal (SPP)?

Amazon’s updated security measures in SPP aim to enhance seller account protection and prevent unauthorized access. SPP is the centralized location for third-party service providers-at work, at home, or in the office-by Amazon-appointed agencies, software vendors, or consultants. These providers can access, maintain, and sell seller accounts under Amazon’s latest security and permissions guidelines through this portal.

Previously, service providers could only connect their SP-API for one seller. With the new changes brought by SPP, Amazon unifies all of these permissions into one framework, ultimately minimizing the administrative procedures and enhancing the safety of the accounts.

Key Benefits of SPP:

• Increased Security: More permissions can be controlled by sellers themselves with regard to the service provider.
• Easier to Access: With one registration, would-be users can now enter into different seller accounts.
• Amazon-Verified Providers: Only registered providers and, therefore, authorized by Amazon would be able to access the seller accounts.

Important Note: For Amazon 3P sellers who rely on external agencies, understanding how Amazon’s seller ecosystem evolves is critical for long-term success. 

If your current service provider fails to register in SPP before the deadline, then he will not have access to your account.

Migration Deadline and What It Means for 3P Sellers

Amazon has mandated that all third-party service providers transition to the Solution Provider Portal before the deadline. After this date, any provider not registered through SPP will no longer be able to access seller accounts through SP-API.

Amazon’s API restrictions can impact sellers’ ability to track critical metrics related to advertising, inventory, and fulfillment performance.

Important: Without proper data access, sellers risk inefficiencies in demand forecasting, order fulfillment, and inventory turnover.

How Third-Party Service Providers Can Register in the SPP

If you work with an Amazon agency or external service provider, it’s crucial they complete the SPP registration before the deadline. Here’s how they can do it:

1. Create an Amazon Developer Account

Service providers must create an Amazon Developer Account in order to begin the registration process. They can sign up through the Amazon Developer Portal.

2. Apply for the Solution Provider Program

Providers need to submit an application on the Solution Provider Portal Registration Page. Amazon will review their application and verify their eligibility.

3. Complete the Business Profile and Verification

• Service providers must provide accurate business details, including legal entity name, website, and business description.

• Amazon may require additional documentation to verify legitimacy.
• Providers must agree to Amazon’s terms and conditions for service providers.

4. Set Up and Configure SP-API Permissions

Once approved, the providers have to configure their SP-API permissions to gain secure access to seller accounts. Amazon is enforcing strict security, allowing providers only limited access that is necessary. 

5. Connect With Sellers

After registration, service providers must link their accounts to their seller clients. Sellers will receive an authorization request, which they must approve in Seller Central.

What 3P Sellers Need to Do Right Now

To prevent disruptions, Amazon 3P sellers should take these steps:

• Check with your service providers: Ask if they have completed the SPP registration. 
• Review your account permissions: Ensure that only registered providers have access. 
• Monitor your Seller Central notifications: Amazon will send updates about the migration process. 
• Prepare a backup plan: If your provider is not registered, you may need to find an Amazon-verified provider.
• Explore Expansion Opportunities: Some sellers may even consider expanding into new international markets to diversify revenue streams.

Common Questions About the SPP Migration

1. What happens if my service provider is not registered before the deadline?

If a service provider does not complete the registration, they will lose access to your Amazon account through SP-API.

2. How can I verify if my service provider is registered?

You can ask your service provider directly or check in Seller Central under Account Permissions to see their status.

3. Are there any fees for service providers to register in SPP?

As of now, Amazon does not charge a fee for registration in the Solution Provider Portal. However, service providers must comply with Amazon’s verification process and security guidelines.
