Table of Contents
Introduction
If you sell on Amazon, you’ve likely compared FBA (Fulfilment by Amazon) with SFP (Seller Fulfilled Prime). Both unlock Prime eligibility, but the operational model and total landed cost differ significantly. Choose well and you’ll protect margin, control and growth. Choose poorly and you’ll pay in rising fees, stock constraints and slow inbounds.
The short answer: FBA is easier. SFP is often cheaper. The right route depends on your product type, margins and setup. Looking for hands-on help? Explore our Seller Fulfilled Prime fulfilment, Amazon FBA prep services and multi-channel fulfilment.
What is FBA?
Fulfilment by Amazon (FBA) stores your stock in Amazon’s FCs and handles pick, pack, ship, returns and post-order CS. Your listings show the Prime badge automatically on eligible SKUs. It’s operationally simple but fee-heavy and you sacrifice packaging control and inbound speed.
Official resources: Fulfilment by Amazon (UK) and Seller Central Help.
What is Seller Fulfilled Prime (SFP)?
SFP lets you keep stock in your own warehouse or a 3PL while earning the Prime badge after a performance trial. You retain control of packaging and multi‑channel use of inventory, while Amazon still handles post‑order customer service.
Requirements include same‑day dispatch, next‑day delivery, 99%+ on‑time, 98%+ Buy Shipping compliance and <0.5% cancellations. See SFP (UK) and SFP requirements.
