What is an FBA seller on Amazon?

An FBA seller is a business that sells on Amazon and uses Fulfillment by Amazon. The seller sends inventory to Amazon's warehouses, and Amazon picks, packs, ships, and handles customer service and returns. The seller still controls listings, pricing, ads and inventory.

How do FBA sellers make money?

They earn the difference between the sale price and their total costs: product cost, freight, prep, referral fees, FBA fulfillment and storage fees, and advertising. Profitable sellers keep fees in check by choosing light, compact products and planning inventory so stock does not sit for months.

Is FBA good for beginners?

Often, yes. FBA removes the need for a warehouse and gives you Prime eligibility from day one. Beginners should start with a small first shipment, check fees per unit with Amazon's Revenue Calculator and avoid bulky or fragile items that are expensive to store and ship.

What is the difference between an FBA seller and an FBM seller?

An FBA seller stores stock in Amazon's fulfillment centers and Amazon ships orders. An FBM seller ships orders from their own location or a 3PL. FBA brings Prime eligibility and less operational work; FBM brings more control and avoids FBA storage fees.

Do FBA sellers have to prep their own products?

In the US, yes. Amazon ended its prep and labelling services for US FBA shipments on January 1, 2026. Sellers must bag, wrap and label units to Amazon's standards themselves or pay a third-party prep center to do it before shipping.

What does FBA mean on Amazon?

FBA stands for Fulfillment by Amazon. Instead of shipping orders yourself, you send inventory to Amazon, which stores it and fulfils orders from its network. Amazon's own description says the fulfillment fee covers picking, packing, shipping, customer service and returns.

The opposite is FBM, fulfilled by merchant, where you ship orders yourself or through a 3PL. Many sellers use both; see our full comparison of FBA vs FBM.

How FBA works, step by step

The day to day cycle is simple, even if each step has detail.

You create or match a product listing in Seller Central
You prep and label units, then create a shipment with Send to Amazon
Amazon receives the stock and spreads it across fulfillment centers
A customer orders; Amazon picks, packs and ships, often with Prime delivery
Amazon handles customer service and returns for that order
Amazon pays out sales minus referral, FBA and storage fees

What an FBA seller is responsible for

FBA removes the warehouse work, not the business work. An FBA seller still owns sourcing, quality, listings, pricing, advertising and inventory planning. Since January 1, 2026, US sellers also prep and label their own units, because Amazon ended its prep and labelling services.

Inventory planning is the skill that separates good FBA sellers from struggling ones. Send too little and you stock out, lose rank and may pay low inventory fees. Send too much and you pay storage, aged inventory surcharges and run into capacity limits. Our Amazon FBA inventory management service focuses on exactly this balance.

FBA moves the warehouse, not the business.

Common FBA business models

FBA is a fulfillment method, not a business model. Sellers using it usually fit one of these:

Private label: your own brand, made by a manufacturer; see our Amazon private label guide
Wholesale: buying established brands in bulk and reselling them
Retail and online arbitrage: buying discounted goods to resell
Manufacturers and established brands selling direct on Amazon
Bundles and kits that combine products into a new offer

How much does it cost to be an FBA seller?

Costs fall into a few buckets. The Professional plan is $39.99 per month. Referral fees are a percentage of the sale price, 15% in many categories. FBA fulfillment fees are charged per unit by size and weight, and storage is charged monthly per cubic foot, with much higher rates from October to December.

2026 brought two increases: an average $0.08 per unit rise in FBA fees from January 15, and a 3.5% fuel and logistics surcharge on fulfillment fees from April 17. Our Amazon FBA fees guide breaks down each charge.

Pros and cons of being an FBA seller

FBA trades control and fees for speed and scale.

Pro: Prime eligibility and fast delivery that shoppers trust
Pro: no warehouse, staff or carrier contracts to manage
Pro: Amazon handles customer service and returns
Con: fees that rise with size, weight and time in storage
Con: capacity limits that can cap how much stock you send
Con: less control over packaging and the unboxing experience

How to become an FBA Amazon seller

Start with an Amazon seller account, then register for FBA in Seller Central under Account Info. Check that your products are allowed in FBA and that any gated categories are approved. Prep and label your first shipment, create it in Send to Amazon and ship. Our Amazon FBA requirements checklist covers each rule.

Start small. Send enough stock for a few weeks of expected sales, run Sponsored Products to build early sales history, then scale replenishment as real demand appears.

Is being an FBA seller worth it in 2026?

For most sellers of small and medium products, yes, because Prime delivery and Amazon's customer service usually earn back the fees through higher conversion. It is less attractive for very bulky, slow-moving or low-priced items, where fees can take most of the margin. The answer depends on your numbers, so model each SKU before you commit inventory. Our guide on whether selling on Amazon is worth it goes further.
