SFP (Seller Fulfilled Prime)

Seller Fulfilled Prime lets Amazon sellers display the Prime badge on their listings while shipping directly from their own warehouse. Learn the eligibility requirements, operational standards, and whether SFP is right for your business.

What is Seller Fulfilled Prime (SFP)?

Seller Fulfilled Prime (SFP) is an Amazon program that allows approved third-party sellers to display the coveted Prime badge on their listings and fulfill orders themselves—from their own warehouse or a third-party logistics (3PL) provider—rather than relying on FBA. For customers, the experience is identical to FBA: they see Prime, expect fast delivery, and receive it. The difference is entirely on the backend, where you own the fulfillment operation.

SFP Eligibility and Requirements

  • Must maintain a On-Time Delivery rate of 93.5% or higher across Prime shipments
  • Must offer free 1-day or 2-day delivery to Prime customers in your designated regions
  • Valid Tracking Rate must exceed 99% on all Prime orders
  • Cancellation rate must stay below 0.5% on Prime orders
  • Must purchase shipping exclusively through Amazon Buy Shipping for Prime orders

SFP vs. FBA: How to Decide

FBA removes all fulfillment complexity and automatically qualifies every ASIN for Prime. SFP is the right choice when FBA fees are cost-prohibitive—especially for oversized, heavy, or low-margin products. SFP also makes sense for sellers with established warehouse operations who want Prime eligibility without surrendering inventory control or paying Amazon's per-unit fulfillment fees. The trade-off is a demanding set of performance standards that require significant operational discipline.

The Prime Badge and Its Impact on Buy Box

The Prime badge is one of the strongest conversion signals on the Amazon marketplace. Listings with Prime eligibility consistently outperform non-Prime listings in Buy Box share, click-through rate, and conversion—often by a wide margin. For FBM sellers unable to offer free fast shipping, transitioning to SFP can meaningfully change competitive positioning without moving to FBA at all.

Maintaining SFP Status Long-Term

  • Partner with carriers that offer reliable same-day or next-day pickup and consistent transit times
  • Build buffer stock to prevent order cancellations during demand spikes or supply disruptions
  • Use Amazon Buy Shipping to preserve valid tracking compliance automatically
  • Monitor SFP performance metrics in Seller Central weekly—a single bad period can trigger revocation
  • Consider a 3PL with SFP experience if you can't consistently hit the standards in-house
