What Is Amazon Seller Fulfilled Prime?
Seller Fulfilled Prime (SFP) is Amazon's program that allows qualified sellers to display the Prime badge on their listings while fulfilling orders from their own warehouse or through a third party logistics partner like AMZ Prep, instead of sending inventory to Amazon FBA warehouses.
Your customers see the same Prime badge and get the same 1 to 2 day delivery promise. The difference is that you control your inventory, your packaging, your carrier selection, and your costs. SFP sellers retain the conversion advantage of the Prime badge (3x to 5x higher than non-Prime listings) while avoiding FBA's long term storage fees, placement fees, seasonal surcharges, and inventory limits.
The catch is that Amazon holds SFP sellers to strict performance standards. You need to ship same day, deliver in 1 to 2 days nationwide, maintain 99.8 percent plus on-time rates, and pass a 30 day trial period. AMZ Prep handles all of this operational complexity so you keep the Prime visibility without the FBA costs.

Seller Fulfilled Prime vs FBA vs FBM: Which Is Right for Your Business?
Each Amazon fulfillment program has trade-offs. The right choice depends on your product size, margin structure, and growth goals.
| Feature | FBA | SFP (via AMZ Prep) | FBM |
|---|---|---|---|
| Prime badge | Yes | Yes | No |
| Inventory control | Amazon controls | You control | You control |
| Branded packaging | Not allowed | Full custom branding | Full custom branding |
| Storage fees | Monthly + long-term + seasonal | Transparent warehouse rates | Your own costs |
| Placement fees | Yes (2024+) | None | None |
| Shipping costs | Amazon rates (rising) | 30% lower on average via Prep Parcel | Your negotiated rates |
| Oversized products | High fees, limited options | Purpose built for oversize | No Prime advantage |
| Meltables (summer) | Restricted May through September | Year round with cold storage | No Prime advantage |
| Returns handling | Amazon handles | AMZ Prep manages | You handle |
| Buy Box advantage | Highest | Equal to FBA for Prime | Lowest |
| Multi-channel | FBA only | Same inventory, all channels | All channels, no Prime |
For most mid-market and enterprise sellers, a hybrid strategy works best: FBA for fast-moving standard size SKUs, SFP through AMZ Prep for oversized products, meltables, branded packaging requirements, and inventory you want to control.
How AMZ Prep Hits 2 Day Delivery at 45% Lower Cost
Our routing system evaluates every order in real time and automatically selects the carrier that meets your SFP commitment at the lowest cost.
Carriers we work with:
How the routing works:
Customer's delivery zone relative to nearest AMZ Prep warehouse
Required delivery speed (same day, 1 day, or 2 day)
Package dimensions and weight
Current carrier rates, surcharges, and fuel adjustments
Carrier performance history for that specific zone
A 2 day delivery to Zone 7 might cost $12.50 via UPS Ground from one warehouse, but $7.80 via FedEx Home from a closer location. Prep Parcel routes every order through the optimal carrier automatically.
Sellers using AMZ Prep's strategic routing save an average of 45 percent on shipping costs compared to single carrier fulfillment, while maintaining the on-time rates Amazon demands for SFP.
The Big and Bulky Prime Solution
Amazon's FBA fees for oversized products are punishing. Large Oversize and Special Oversize tiers can cost 5x to 8x standard fulfillment fees. SFP through AMZ Prep eliminates those penalties while keeping the Prime badge.
Nationwide 2 Day Delivery
For items over 18 by 14 by 8 inches or 20 plus pounds, meeting Prime standards through AMZ Prep's strategically located warehouses.
30 to 40% Savings vs FBA
No oversized storage fees, no seasonal surcharges, no placement fees. Transparent warehouse rates with multi carrier rate shopping through Prep Parcel.
3x to 5x Higher Conversions
Prime badge on oversized listings converts at 3x to 5x the rate of FBM competitors. SFP delivers that advantage without the FBA cost structure.
Ship Meltables with Prime, Even in Summer
Amazon's meltable policy restricts FBA for temperature sensitive products from May through September every year. When your chocolates, probiotics, supplements, and cosmetics get pulled from FBA, AMZ Prep keeps your Prime badge active with climate controlled SFP fulfillment operating 6 days a week.

Frequently Asked Questions About Seller Fulfilled Prime
What is Seller Fulfilled Prime and how does it work?
Seller Fulfilled Prime (SFP) is Amazon's program that lets qualified sellers display the Prime badge while fulfilling orders from their own warehouse or through a 3PL partner like AMZ Prep. Customers see the same Prime badge and receive the same 1 to 2 day delivery promise. The seller controls inventory, packaging, and carrier selection instead of sending products to Amazon FBA warehouses.
What are the requirements to qualify for Seller Fulfilled Prime?
SFP requires a 99.8 percent or higher on-time shipment rate, 99.8 percent valid tracking rate, cancellation rate below 0.5 percent, 1 to 2 day nationwide delivery capability, weekend dispatch operations, and use of Amazon Buy Shipping Services. Sellers must pass a 30 day trial period fulfilling at least 100 Prime orders while meeting all performance standards. Amazon limits sellers to 3 trial attempts per year.
How long does the SFP trial period take?
Amazon's SFP trial lasts 30 days. During this period you must fulfill at least 100 Prime orders while meeting all performance standards. You do not display the Prime badge until you pass. AMZ Prep provides daily metric monitoring during the trial to ensure you pass on the first attempt.
How is Seller Fulfilled Prime different from FBA?
With FBA, Amazon stores, picks, packs, and ships your inventory from their warehouses. With SFP, you fulfill orders from your own warehouse or through a 3PL like AMZ Prep while displaying the Prime badge. SFP gives you control over inventory, branded packaging, carrier selection, and costs. There are no FBA placement fees, long term storage fees, or seasonal surcharges.
What happens if I fail the SFP trial?
Amazon limits sellers to 3 trial attempts per year. If you fail, you must wait before trying again. AMZ Prep's trial management process significantly reduces this risk. Our clients pass consistently with 99.8 percent plus on-time delivery through daily monitoring, real time compliance adjustments, and proactive issue resolution.
Is SFP better than FBA for oversized products?
For most oversized sellers, yes. FBA's Large Oversize and Special Oversize tiers cost 5x to 8x standard fulfillment fees. SFP through AMZ Prep eliminates those penalties while keeping the Prime badge. Sellers typically save 30 to 40 percent on fulfillment costs for oversized products compared to FBA, with the same Prime conversion advantage.
What shipping carriers can I use for SFP?
Amazon requires SFP sellers to use approved carriers including UPS, FedEx, USPS, DHL, and Amazon Shipping.

Our multi carrier routing system automatically selects the optimal carrier for every order based on delivery zone, package dimensions, and current rates.
Can I use the same inventory for SFP and other sales channels?
Yes. With AMZ Prep, your SFP inventory fulfills orders across Amazon, Shopify, Walmart, Target, Wayfair, and any custom channel through our open API. One inventory pool serves all platforms, eliminating the need to split stock between FBA and other channels.
Does SFP work for temperature sensitive or meltable products?
Yes. Amazon restricts FBA for meltable products from May through September each year. AMZ Prep is Amazon approved for SFP with temperature controlled facilities, keeping your Prime badge active year round for chocolates, probiotics, supplements, and other temperature sensitive products.
