Fulfillment By Amazon (FBA): Benefits, Costs & Requirements
Every Amazon order has to get from a shelf to a doorstep. For many sellers, Amazon handles that middle. Fulfillment by Amazon (FBA) is the default way to sell on the platform, but its fees and rules catch lots of people off guard.
In this guide, we will cover how FBA works, what it costs, what Amazon requires, and how it compares to FBM and Seller-Fulfilled Prime (the other two possibilities for third-party sellers partnering with Amazon).
TL;DR
FBA meaning: you send inventory to Amazon, and Amazon stores it, then picks, packs, ships, and handles returns and customer service.
The upside: the Prime badge, built-in customer trust, and hours back to grow your brand.
The costs: a selling plan ($39.99/month for Professional or $0.99 per item for Individual), a referral fee on every sale, per-unit fulfillment fees, monthly storage, and surcharges on inventory that sits too long.
The requirements: an Amazon selling plan, eligible products, and inventory prepped and labeled to Amazon's specs.
The catch: FBA isn't your only path. FBM and Seller-Fulfilled Prime (SFP) give you more control, and a 3PL partner can prepare you for FBA or run either one for you.
FBA Meaning: What Is Amazon FBA?
It’s quite straightforward. Fulfillment by Amazon (FBA) is a program where you ship products into Amazon's fulfillment network, and Amazon handles what comes after: storage, picking, packing, shipping, returns, and customer service. Your listings earn the Prime badge, so Prime members get fast, free delivery, which tends to lift conversion at checkout.
People sometimes ask what an Amazon FBA store is, expecting a separate storefront. There isn't one. FBA is a fulfillment method, not a place shoppers visit. You can run your Amazon store and fulfill through FBA, FBM, or a mix. FBA can even ship to your other channels through Multi-Channel Fulfillment.
Amazon FBA ecommerce has grown right alongside online shopping, which now makes up about 16.9% of all U.S. retail sales, close to one in six retail dollars, according to Federal Reserve data.
How Does Amazon FBA Work?
Amazon becomes your warehouse, packing crew, and shipping desk rolled into one. Here's the flow in five steps:
Enroll Your Products
From Seller Central, add new listings as FBA or convert existing ones.
Prep & Label
Get each unit ready to Amazon's specs, including barcodes and protective packaging.
Ship It In
Create an inbound shipment and send inventory to Amazon's fulfillment centers. Amazon's partnered carrier rates can keep those costs down.
Amazon Fulfills
Once your stock checks in, Amazon stores it, then picks, packs, and ships every order.
Handling The Rest
Returns and customer service are on Amazon.
Most of the work for an FBA seller sits up front, in prep and inventory planning. After that, fulfillment mostly runs itself.
The Benefits Of FBA For Your Ecommerce Business
Most third-party sellers run at least part of their catalog through FBA. For a growing FBA business, the appeal is practical.
Prime Eligibility
The badge puts your products in front of millions of shoppers who filter for fast, free shipping.
Instant Trust
Amazon-branded delivery and support reassure buyers if they've never heard of your brand.
Time Back
Offload picking, packing, shipping, and returns, so that you can spend your hours on products and growth.
Room To Scale
Peak season spikes? Amazon absorbs them without you leasing space or hiring extra crew members.
What Does Fulfillment By Amazon Cost?
Fulfillment by Amazon runs on a pay-as-you-go model, and the charges land in a few buckets.
| Fee | What It Covers |
|---|---|
| Selling Plan | $39.99/month for Professional, or $0.99 per item for Individual, plus selling fees |
| Referral Fee | A cut of each sale, commonly around 15%, varying by category |
| Fulfillment Fee | Per unit, based on size and weight, covering pick, pack, ship, service, and returns |
| Monthly Storage | Based on volume and season, with higher rates in Q4 |
| Aged-Inventory Surcharge | Extra charges on units sitting 181 days or longer |
All in, FBA fees can eat 30% to 40% of your sale price, so reflect them from the start and keep stock moving to avoid storage charges. To pin down the numbers on a specific product, run it through Amazon's free Revenue Calculator in Seller Central, which estimates fees and profit per unit. Rates change often, so confirm the current figures there before you commit.
FBA Requirements: What You Need And What's Eligible
The FBA requirements split into two categories: getting set up, and getting your products ready.
Setup is easy. You need an active Amazon selling account, Individual or Professional, with products enrolled in FBA. Almost anyone qualifies.
Getting products ready is where sellers trip up. Not everything is eligible: hazardous materials, alcohol, and some restricted categories are out, and anything with an expiration date carries shelf-life rules. Whatever qualifies has to reach Amazon already prepped to specs:
FNSKU barcode labels on every unit
Poly-bagging with suffocation warnings where required
Bubble wrap or protective packaging for fragile items
Correct carton labeling on the inbound shipment
Get any of that wrong, and Amazon can hold your shipment, add a surcharge, or turn it away at the dock. That is why many sellers hand prep to someone who does it every day, like jam-n.
Amazon Fulfillment Options Compared: FBA vs FBM vs SFP
FBA is not automatically the right move for everyone. You have three ways to fulfill Amazon orders: FBA, FBM (Fulfillment by Merchant), and SFP (Seller-Fulfilled Prime). Here's how they compare.
| FBA | FBM | SFP | |
|---|---|---|---|
| Who Stores & Ships | Amazon | You or your 3PL | You or your 3PL |
| Prime Badge | Yes, automatic | No | Yes, if you meet Amazon's standards |
| Customer Service & Returns | Amazon | You | You |
| Packaging & Branding Control | Low | Full | Full |
| Extra Amazon Fees | Fulfillment and storage | None beyond the referral fee | None beyond the referral fee |
| Best Fit | Small, fast-moving products | Bulky, heavy, or high-control goods | Sellers who want Prime plus control |
Many sellers split the catalog and run more than one.
Returns are worth weighing either way. The National Retail Federation puts the online return rate at roughly 19.3% of sales, about one order in five. Whether Amazon handles them or you do, returns cost money, and someone has to deal with them.

FAQs
What Is Fulfillment By Amazon?
Fulfillment by Amazon (FBA) is a program where you send inventory to Amazon, and Amazon stores it, then picks, packs, ships, and handles customer service and returns. Your listings also earn the Prime badge.
What Is FBA Shipping?
FBA shipping is the inbound leg: sending your prepped, labeled inventory into Amazon's network. It's separate from the outbound orders Amazon ships to customers once your stock checks in.
Is Amazon FBA The Same As Having An Amazon Store?
No. An Amazon store is where you list and brand products. FBA is one way to fulfill those orders. You can have a store and still use FBM or a 3PL to ship.
How Much Does FBA Cost Per Month?
There's no separate flat FBA subscription. You'll pay for a selling plan (about $39.99/month for Professional), plus per-unit fulfillment fees and monthly storage that scale with your volume.
What Is Amazon's Referral Fee?
It's the commission Amazon takes on every sale, and you pay it whether you use FBA, FBM, or SFP. Most categories run 15%, with the full range spanning roughly 8% to 45% and a $0.30 minimum per item. It's charged on the total the customer pays, shipping included. Check your category in Seller Central before you set prices.
Do I Still Need A 3PL If I Use FBA?
Many FBA sellers do. A 3PL like jam-n handles prep, overflow storage, and your non-Amazon channels, keeping one steady operation across FBA, FBM, and DTC.
