Seller Fulfilled Prime (SFP) puts the Prime badge on Amazon offers you ship yourself, or that a 3PL ships for you, without sending inventory to FBA. Enrollment is open, whatever older guides say: Amazon's Seller Fulfilled Prime trial and enrollment page sends any seller who meets the prequalification bar straight to trial registration. The catch is what comes after. You keep the badge only while you meet Amazon's weekly SFP performance requirements: 93.5% on-time delivery, 99% valid tracking and the delivery-speed minimums for your size tier, every week, Sunday to Saturday. Your order cutoff and your carrier pickup decide much of that, which is also where a 3PL helps or hurts.
Getting in takes two steps: prequalify on your last 90 days of seller-fulfilled orders, then pass a 4-week trial with at least 100 Prime packages.
Seller Fulfilled Prime requirements at a glance
These are Amazon's numbers as of October 2026. Amazon updates them with notice, so check its enrollment and performance pages before you register for a trial.
Phase | What Amazon requires |
|---|---|
Prequalify (your past 90 days) | A US default shipping address, a Professional selling account, at least 100 seller-fulfilled packages, a cancellation rate under 2.5%, a valid tracking rate above 95%, and a late shipment rate under 4% |
Trial (4 weeks, 28 days) | 100 or more packages from Prime trial orders, Prime packages shipped every week, and every SFP performance requirement met. Missing any requirement in two of the four weeks fails the trial. |
Ongoing (reviewed weekly, Sunday to Saturday) | On-time delivery of at least 93.5%, a valid tracking rate of at least 99%, a cancellation rate of 0.5% or less, the delivery speed minimums for your size tier, and at least 100 Prime packages a month |
How to get Seller Fulfilled Prime, step by step
- Check your last 90 days against the prequalification bar in the table. The trial asks for a cancellation rate of 0.5% or less, against under 2.5% to prequalify, so if your late shipments or seller cancellations sit near the prequalification line, fix that first.
- Register for the trial and set up the Prime shipping template. Registering gives you access to the template, which is where you configure the Prime offers for the size tiers you signed up for. Put the SKUs you want to trial on it.
- Plan your volume around the start date. The trial begins the Sunday after you register, at 00:00 Pacific time, and runs for 4 weeks. You need at least 100 Prime packages across it, with some shipped every week.
- Set your order cutoff to match your carrier pickup. Amazon counts a unit as shipped at the carrier's first scan, not when you confirm shipment in Seller Central, and an order placed before your cutoff needs that first scan the same day to count as shipped on time. On-time shipment is only a supporting metric, but items shipped late are less likely to be delivered on time.
- Pass the trial, then hold the numbers. When the trial ends with every requirement met, Amazon enrolls you automatically and your eligible offers start showing the Prime badge for the size tiers you passed. If you then ship fewer than 100 Prime packages in a month, or ship them unevenly, Amazon limits your maximum daily Prime order volume until you are back above that level.
If you don't pass, you can restart the trial at any time while you still meet prequalification, up to three attempts per calendar year.
Delivery speed and size tiers
Since November 5, 2025, Amazon has let you enroll and be evaluated in each size tier on its own, and performance in one tier does not affect another. You don't have to trial every tier at once. A brand that sells mostly standard-size items with a few oversized ones can trial the standard tier first and add oversize later.
Delivery speed is measured from the shopper's side. Amazon counts the Prime customer page views where your offer was shown with a delivery promise inside each window, so a next-day promise counts toward all three columns. The current minimums on Amazon's performance requirements page are:
Size tier | 1 day or less | 2 days or less | 5 days or less |
|---|---|---|---|
Standard size | 40% or more | 75% or more | 90% or more |
Oversize | 15% or more | 45% or more | 80% or more |
Extra large | N/A | 25% or more | 60% or more |
Amazon refreshes these minimums quarterly, gives at least 45 days' notice before raising one, and may adjust them over the holidays. Your order cutoff, your weekend operations and your carrier's weekend service all change the date a shopper sees, which is why an offer set up for two-day delivery can still show a five-day promise. Amazon expects enrolled and trial sellers to operate on weekends.
Peak season also changes the trial timeline. The last trial start date for the 2026 peak was September 19, 2026, and a seller who passes between October 18 and December 31, 2026 gets the Prime badge after that period ends.
SFP vs FBA vs seller-fulfilled without Prime
Seller Fulfilled Prime | Fulfillment by Amazon (FBA) | Seller-fulfilled without Prime | |
|---|---|---|---|
Where inventory sits | With you or your 3PL | In Amazon's fulfillment network | With you or your 3PL |
Who packs and ships | You or your 3PL, against Amazon's Prime delivery metrics | Amazon | You or your 3PL, on your own shipping settings |
Prime badge | Yes, after you pass the trial | Yes, on eligible offers | No |
What it costs you | Your own packing and shipping costs | Amazon's FBA fees | Your own packing and shipping costs |
FBA hands the shipping and the fee schedule to Amazon; our breakdown of Amazon FBA fees shows what that costs. SFP keeps your Amazon stock in the same place you ship your website orders from, and in exchange Amazon checks your delivery numbers every week. For the other ways to ship Amazon orders, see Amazon seller shipping options.
Can a 3PL ship your Seller Fulfilled Prime orders?
Yes. SFP is seller-fulfilled, and Amazon's enrollment page speaks to "sellers and fulfillment partners" directly. A 3PL can store your inventory, pick and pack each Prime order, and get it a carrier scan before the cutoff. Your seller account still owns the trial, the metrics and the badge. Amazon is explicit about where its own role ends: SFP qualification "depends solely on actual delivery performance during the trial period," and Amazon "is not responsible for commitments a third-party logistics provider or other partner makes to its clients regarding SFP qualification, timeline, or performance outcomes." It also says sellers and fulfillment partners must check for themselves whether SFP is feasible given their network, carrier relationships and geographic coverage.
That applies to Simpl too. We ship Amazon orders along with orders from Shopify and the other platforms we connect to. Orders received before 12pm CT ship the same day on UPS, USPS or FedEx, and tracking numbers sync back to the Amazon order. That covers the packing, cutoff and carrier-scan side of the metrics above. We don't promise that you'll pass the trial or keep the badge, because Amazon decides that on delivery results.
Before you start a trial with any 3PL, ask what its same-day cutoff is, when the carrier picks up, how it handles weekends, and which carrier services it will use for your Prime orders. Our guide to 3PLs for Amazon sellers covers the wider questions.
On cost, Simpl starts at $7 per order with a $750 monthly minimum billed as pay-the-difference: if a month's orders bill under $750, you pay only the gap. That is roughly 90–100 orders a month for light packages on standard shipping; heavier, larger or faster shipments reach it with fewer orders. If your Amazon and website orders together bill well under $750 a month, packing your own Prime orders through the trial may be the better fit for now. Simpl pricing has the details.

Seller Fulfilled Prime FAQ
Is Seller Fulfilled Prime enrollment open?
Yes. Any seller who meets the prequalification bar can register for the trial from Amazon's trial and enrollment page.
How many orders do I need for Seller Fulfilled Prime?
At least 100 seller-fulfilled packages in the past 90 days to prequalify, 100 or more Prime packages over the 4-week trial, and at least 100 Prime packages a month once enrolled. Ship fewer than that in a month and Amazon limits your daily Prime order volume.
How long is the SFP trial?
Four weeks (28 days), starting the Sunday after you register. If you pass during a restricted graduation period, such as October 18 to December 31, 2026, the Prime badge turns on after that period ends.
What happens if I fail the SFP trial?
Missing any requirement in two of the four trial weeks fails the trial. You can restart it at any time while you still meet prequalification, up to three attempts per calendar year.
How can I tell if an Amazon offer is SFP or FBA?
Look at the "Ships from" line under the Buy button. An FBA offer reads "Ships from Amazon"; an offer the seller fulfills reads "Ships from" followed by the seller's name, as Amazon's customer help explains. A seller-fulfilled offer that also shows the Prime badge is an SFP offer, because Seller Fulfilled Prime is how Amazon puts the badge on offers sellers ship themselves.
Is Seller Fulfilled Prime worth it for a small brand?
It depends on whether you can hit the numbers every week. SFP fits a brand that already ships its Amazon orders on time with valid tracking, sells the same products on its own site, and would rather not move stock into FBA. It is a harder fit if your Amazon volume is uneven, because Amazon limits daily Prime orders for sellers under 100 Prime packages a month, or if nobody can operate on weekends, which Amazon expects of SFP sellers.
