3PS - Amazon Glossary

A Third-Party Seller (3PS) is any non-Amazon entity that uses Amazon’s Seller Central platform to offer products to customers. These sellers are not employees or divisions of Amazon - they are independent businesses that manage their own inventory, pricing, listings, and operations.

There are millions of 3PS accounts globally, including:

• Private label brands
• Resellers
• Wholesalers
• Dropshippers
• Handmade/artisan creators
• Local businesses

Third-party sellers can use either:

• FBA (Fulfillment by Amazon) - Amazon handles storage and shipping
• FBM (Fulfillment by Merchant) - the seller handles fulfillment

The listing will typically show:

• "Sold by [Seller Name], Fulfilled by Amazon" (FBA)
• or "Ships from and sold by [Seller Name]" (FBM)

Being a 3PS gives sellers full control over their business, and Amazon provides tools for advertising, promotions, reviews, and reporting. As of today, third-party sellers account for the majority of units sold on Amazon.
