What Amazon measures, and how we keep you inside it
Amazon scores Seller Fulfilled Prime sellers every week. Miss a threshold and the Prime badge comes off. Amazon also raised its minimum delivery-speed requirements on July 6, 2026, so the margin for error is smaller than it was.
On-time delivery: 93.5% or better
Orders ship the same day when they arrive before the daily cutoff, using Amazon-approved carrier services so delivery promises hold.
Valid tracking: 99% or better
Every package is labeled and scanned out of our system, and tracking is pushed back to Seller Central automatically.
Cancellations: under 0.5%
Real-time inventory sync between our floor and your Amazon listings, so you are not selling stock that is not on the shelf.
Seller Fulfilled Prime or FBA?
Many brands run both. Here is how we help decide which SKUs belong where.
SFP tends to win when
- Products are oversized, heavy or slow-moving, where FBA fees and storage limits bite
- You sell the same stock on Shopify, wholesale or other marketplaces
- You want control over packaging, inserts and brand experience
- FBA inventory limits keep cutting your replenishment
FBA tends to win when
- Products are small, light and fast-selling
- Customers across the whole country expect next-day delivery
- Amazon is nearly all of your sales
- You ship well under 100 Prime orders a month
Going the FBA route? We prep and ship your inbound inventory too. See Amazon FBA prep.
Passing the Prime trial
Before the badge appears, Amazon makes you ship at least 100 Prime trial orders while meeting every metric. The badge does not show during the trial, so the orders come slowly and every one counts.
Before the trial
We review your shipping templates, carrier setup and the regions you will offer Prime in, so the promises Amazon shows are ones we can keep.
During the trial
Trial orders are flagged on our floor and shipped first. We watch your scorecard with you each week.
After you qualify
The same daily cutoff, tracking and inventory sync keep you inside the metrics as volume grows.

Seller Fulfilled Prime FAQ
Can a 3PL ship Seller Fulfilled Prime orders?
Yes. Amazon allows sellers to use a fulfillment partner for SFP, as long as the account meets every performance requirement. The seller stays responsible for the metrics, which is why the partner's cutoff, tracking and inventory accuracy matter.
What are the Seller Fulfilled Prime requirements?
Amazon requires an on-time delivery rate of at least 93.5%, a valid tracking rate of at least 99% and a seller cancellation rate below 0.5%, measured weekly. New sellers must first pass a trial of at least 100 Prime orders.
Can one East Coast warehouse cover Prime nationwide?
It depends on your products and your shipping templates. Allentown reaches the Northeast fast by ground. For full national coverage, many brands pair it with our Los Angeles location or use regional Prime templates. We map this with you before the trial.
Can I run SFP and FBA at the same time?
Yes. Many brands keep fast-moving SKUs in FBA and ship bulky or multichannel SKUs through SFP from our building.
