This Amazon FBA guide for beginners shows you, step by step, how Fulfillment by Amazon works. You will learn what Amazon does for you, what stays your job, how the fees are built up, and how to send your first shipment without the mistakes that cost new sellers time and money. It is written for new sellers and small brands in any country who want a clear picture before they send stock to an Amazon warehouse.
If you are still deciding whether to use FBA or ship orders yourself, that comparison needs its own article. Here, the focus is on how FBA works once you have chosen it.
What is Amazon FBA and how does it work?
With Fulfillment by Amazon (FBA), you send your products in bulk to Amazon fulfillment centers. Amazon stores them. When a customer buys, Amazon picks, packs and ships the order, answers customer questions about delivery, and handles returns. You still own the stock, the listing and every business decision.
The FBA process in five stages
- List: you create a product listing in Seller Central and set it to be fulfilled by Amazon.
- Prepare: you (or your supplier) package and label every unit to Amazon’s requirements.
- Ship: you create a shipment in Seller Central and send the boxes to the fulfillment centers Amazon assigns.
- Receive: Amazon checks in your units and makes them available for sale.
- Fulfill and pay: Amazon ships each order and pays you the sale amount minus its fees.
What is still your responsibility
Sourcing a good product, writing the listing, pricing, advertising, compliance, stock planning and watching your margins after fees.
Before you start: account, product and cost checks
Seller account and selling plan
You need a Seller Central account in the marketplace where you want to sell, for example Amazon.com, Amazon.co.uk or Amazon.de. Amazon usually offers more than one selling plan, each with a different fee structure, so compare the current options on the official site. Registration asks for identity documents, business details, a bank account and tax information, and Amazon verifies them before you can sell. If you are based in the UAE, my Amazon UAE seller guide walks through that marketplace as one example.
Check that your product can use FBA
Some categories need approval before you can list. Some products count as dangerous goods (for example items with lithium batteries, aerosols or flammable liquids) and need extra documents and review. A few products are not allowed in FBA at all. Check all of this in Seller Central before you pay a supplier. This one step saves many beginners from being stuck with stock they cannot sell.
Know your numbers first
Before ordering inventory, work out your profit per unit: selling price, minus product cost, minus shipping to Amazon, minus Amazon’s referral fee, minus the FBA fulfillment fee, minus storage, advertising and an allowance for returns. Seller Central has a revenue calculator that estimates Amazon’s fees for a product. My advice: if the margin only works when everything goes perfectly, the product is too risky for a first launch.
Step 1: Create your listing and set it to FBA
You can either create a new product listing (common for private label brands) or add an offer to an existing listing if you sell the exact same product as others. In the offer details, choose fulfillment by Amazon. You can also convert an existing listing that you currently ship yourself.
FBA handles delivery, but it does not sell the product for you. Your title, bullet points, images and description still decide whether shoppers click and buy. Do proper research with my keyword research guide, then follow the steps in my Amazon listing optimization post before you send stock.
Step 2: Prepare, package and label your units
Barcodes: FNSKU or manufacturer barcode
Amazon tracks every unit by barcode. The FNSKU is Amazon’s own label that links a unit to your seller account. For some products, Amazon lets you use the manufacturer barcode (UPC or EAN) instead, but then your units may be stored together with identical units from other sellers. Many private label sellers prefer FNSKU labels so they always know which stock is theirs. Check which options your account offers.
Prep rules to follow
- Each unit must be packed so it survives handling and shipping on its own.
- Loose items may need a poly bag, and many bags need a suffocation warning.
- Fragile items need protective packaging such as bubble wrap or a sturdy box.
- Products with expiry dates must show the date clearly in the format Amazon requires.
- The barcode must be easy to scan, with any other barcodes on the packaging covered.
In some marketplaces Amazon offers prep and labeling for a fee. You can also ask your supplier to apply FNSKU labels at the factory.
Box labels and limits
Every carton needs its own shipment label and box content information, and there are carton size and weight limits. Read the current prep requirements in Seller Central help for your marketplace.
Step 3: Create your shipment and send inventory to Amazon
You create inbound shipments in Seller Central using Amazon’s send-inventory workflow. The exact screens change, but the steps are usually:
- Select the products and quantities you want to send.
- Enter packing details: units per box, box dimensions and weight.
- Review placement. Amazon may split your inventory across several fulfillment centers. In some marketplaces you can choose between placement options, and fees may differ between them.
- Choose a shipping method: small parcel for boxes, or freight for pallets. Use Amazon’s partnered carrier where available, or your own carrier.
- Print box labels and, for pallets, pallet labels.
- Hand over the shipment and make sure tracking is added.
Shipping from another country
Many sellers manufacture abroad and ship straight to Amazon. In that case you are responsible for importing the goods: customs clearance, duties, taxes and correct paperwork. Amazon generally does not act as your importer. Work with a freight forwarder or customs broker who knows Amazon’s delivery appointment and labeling requirements.
Step 4: What happens after Amazon receives your stock
Receiving can take time, so track each shipment in Seller Central. If the received quantity does not match what you sent, check the shipment details and use the reconciliation options or open a case with your proof.
Once units are available, your offer can show fast delivery and, in marketplaces with Prime, the Prime badge. Amazon handles delivery questions and returns for FBA orders. Returned units are checked; sellable units go back into stock and damaged ones are marked unfulfillable, which you can ask Amazon to return to you or dispose of. Amazon pays out your balance on a regular cycle after fees, and you can see each deduction in your payment reports.
Understanding FBA fees without guessing
I will not quote fee amounts here, because they change regularly and differ by marketplace, product size and category. What you need to understand is the structure:
- Referral fee: a percentage of the sale price charged on every sale, FBA or not, which varies by category.
- Fulfillment fee: charged per unit sold, based on size tier and weight.
- Monthly storage fee: based on the space your stock takes up, often higher in the end-of-year peak season.
- Aged inventory surcharges: extra charges for stock stored for a long time.
- Removal and disposal fees: when you ask Amazon to send back or destroy units.
- Inbound and service fees: in some marketplaces, placement fees, prep services or labeling services.
Always confirm current rates on Amazon’s official Fulfillment by Amazon page and in Seller Central for your marketplace, and recheck your margins whenever Amazon announces fee changes. Also check the dimensions and weight Amazon records for your product. If they are wrong, your fees will be wrong too.
Managing FBA inventory and avoiding common mistakes
- Set a reorder point: average daily sales multiplied by your full lead time (production plus shipping plus receiving), plus some safety stock.
- Do not overstock: too much stock means higher storage fees, and Amazon may apply storage or capacity limits to your account.
- Fix stranded inventory quickly: this is stock sitting in a warehouse with no active listing, so it cannot sell.
- Plan for peak season: Amazon often sets earlier inbound deadlines before busy periods, so send stock early.
- Sell on other channels: in many marketplaces, Multi-Channel Fulfillment lets Amazon ship orders from your own store. If you plan to build one, see my Shopify beginner guide.
Common beginner mistakes with FBA
- Buying stock before checking category approval and dangerous goods rules.
- Sending units with wrong, missing or unscannable labels.
- Sending far more stock than you can sell in a reasonable time.
- Launching with a weak listing and expecting FBA alone to create sales.

Frequently asked questions
How much money do I need to start Amazon FBA?
There is no fixed amount. It depends on product cost, order quantity, shipping, Amazon fees, advertising and a buffer for surprises. Start with a quantity you can afford to lose while you learn, and calculate it from real supplier quotes and Amazon’s fee calculator.
Can I use FBA if I live outside the marketplace country?
Often yes. Sellers from many countries sell through FBA on marketplaces abroad. You will need to meet that marketplace’s registration, tax and import requirements, so check Seller Central help and, for tax, the relevant tax authority or an accountant.
Does FBA help me win the Buy Box?
It can help, because fast and reliable delivery matters to Amazon. But price, stock level and your account performance also count, so FBA alone does not guarantee the Buy Box.
Can FBA ship orders from my own website?
In many marketplaces, yes, through Multi-Channel Fulfillment. It has its own fees and rules, so check the current details in Seller Central for your region.
Conclusion: start small and follow the rules closely
FBA takes storage, packing, delivery and returns off your hands, but it rewards sellers who prepare carefully. Check that your product is allowed, know your margins, label every unit correctly and send a sensible first quantity. Then watch your inventory and fees every week. Do that, and FBA becomes a reliable system you can grow on, not an expensive surprise.
