Getting Started With Fulfillment by Amazon (FBA): 2027 Guide

Fulfillment by Amazon (FBA) means you send inventory to Amazon's fulfillment centers, and Amazon stores it, picks, packs, ships, and handles customer service and returns for those orders. Your listings get the Prime badge automatically, which is the main reason most private label sellers start here. This guide walks through how to get started with FBA heading into 2027: how the model works, what it costs, how to send your first shipment, and the mistakes that quietly eat margin.

One note on numbers. Amazon changes fee schedules often, and third-party blogs frequently disagree with each other. Use the figures below as a planning baseline, and confirm every rate in Seller Central's fee schedule and Revenue Calculator before you commit to a product.

How FBA works

The flow is simple. You create a listing, create an inbound plan in Seller Central, ship units to the fulfillment centers Amazon assigns, and Amazon receives them as sellable inventory. When a customer orders, Amazon ships it and handles the support ticket if something goes wrong. You are still the seller of record, so you keep control of pricing, listing content, and advertising.

What you hand over, and what you keep

Amazon takes over storage, fulfillment, delivery, customer service, and returns processing. You keep sourcing, listing quality, pricing, inventory planning, and ads. Most FBA problems are not fulfillment problems. They are forecasting problems: ordering too much (storage and aged inventory fees) or too little (stockouts and low-inventory fees).

Who FBA suits best

FBA tends to work best for standard-size, lightweight, fast-moving products, and for launches where the Prime badge matters for conversion and ranking. It is a weaker fit for heavy or oversized items, slow movers, and low-margin products where fees consume the spread. If you are weighing it against shipping yourself, see our Amazon FBM guide.

What FBA costs in 2026 and what to plan for in 2027

Think in five buckets: referral fees, fulfillment fees, storage fees, inbound costs, and penalty-style fees.

Referral fees

Referral fees are a percentage of the sale price and depend on category. Third-party summaries of the 2026 schedule put most default categories at 15 percent, consumer electronics at 8 percent, and apparel at 17 percent, with tiered rates for categories like grocery and jewelry. Amazon's own announcement for 2026 did not list a referral fee increase. Check the category page in Seller Central for your exact rate.

Fulfillment fees

Amazon announced an average increase of about $0.08 per unit sold in FBA fees for 2026, effective January 15, 2026. Separately, multiple industry sources report a 3.5 percent fuel and logistics surcharge on FBA fulfillment fees in the US that began on April 17, 2026. Amazon described it as temporary, but no end date was given in the sources we reviewed, so model it as permanent until told otherwise. It applies to the fulfillment fee, not to referral or storage fees.

Storage and aged inventory

Storage is charged per cubic foot, with higher rates in October through December. Aged inventory surcharges kick in earlier than they used to, with reports of the threshold moving to 181 days. If you carry long-tail SKUs, this is where margins leak. Set a rule: any SKU with more than 90 days of cover gets a discount, bundle, or removal plan.

Inbound and prep

Amazon discontinued its in-house prep and labeling services on January 1, 2026, according to industry reports, and charges defect fees for non-compliant units. Your supplier or prep center needs to deliver correct labels, polybags, and packaging. Build this into your purchase order terms so it is the factory's problem, not yours.

Low-inventory-level fee

Amazon applies a per-unit fee when FBA stock at the SKU level runs below roughly 28 to 35 days of cover. The practical lesson: stockouts cost more than lost sales. Keep a buffer, and use the Amazon sales calendar to plan restocks ahead of peak events.

Getting started: step by step

1. Set up your seller account

Register a Professional seller account, which is the plan most FBA sellers use. You will need identity verification, a bank account, a credit card, and tax details. Verification can take days, so start before your inventory is ready.

2. Choose and validate a product

Run the numbers before you order. Use the FBA Revenue Calculator to enter your landed cost, estimated price, size, and weight, then check that net profit and return on investment clear your minimum. Validate demand and competition with research tools. Our roundup of the best Amazon seller tools covers the main options.

3. Create the listing

Create the product listing with a strong title, bullets, images, and backend keywords. Listing quality drives conversion, and conversion drives ad efficiency. See our guide to Amazon listing optimization tools. Choose "Fulfilled by Amazon" when you set the offer.

4. Prepare units and labels

Each unit needs a scannable barcode, either the manufacturer barcode if you use commingling (check eligibility first) or an Amazon FNSKU label. Confirm prep requirements for your category, such as bagging, bubble wrap, or set labeling. Get your supplier to do this at the factory.

5. Create the inbound plan and ship

In Seller Central, create an inbound plan, enter quantities and packing details, then choose placement options and a carrier. Amazon may split a shipment across several fulfillment centers, which affects inbound placement cost, so compare the options. Print box labels, attach them, and ship via Amazon's partnered carrier or your own.

6. Monitor receiving and go live

Track check-in in the inbound shipment view. Units become sellable as they are received. Watch for receiving discrepancies and file claims promptly if units are lost.

Common first-year mistakes

• Ignoring total fees. A product that looks fine at a 15 percent referral fee may fail once fulfillment, storage, returns, and ads are included.
• Overordering. Cash tied up in slow stock is the most common reason new sellers stall.
• Weak listings at launch. FBA gives you Prime, not conversion.
• No restock process. Set a weekly inventory review and a reorder point based on lead time plus a safety buffer.
• Skipping the account health checks. Keep an eye on IPI-style inventory health signals and policy notices in Seller Central.

The GTM angle

If you sell services or software to Amazon sellers, new FBA sellers are one of the best-defined audiences you can target. They have clear, time-bound pains: listing creation, product research, prep and logistics, PPC setup, and inventory planning. Each pain maps to an offer.

Build your ICP by stage. Pre-launch sellers need research tools and listing help. Sellers with 5 to 20 SKUs need PPC management and inventory forecasting. Sellers above that need analytics, reimbursement recovery, and 3PL alternatives.

Then use triggers. Fee schedule announcements, the move into Q4 storage pricing, and new brand registrations are all events you can reference in a cold email. A subject line tied to a real event, such as "Q4 storage fees start in October, here is a restock checklist", outperforms generic pitches because it gives the seller a reason to read now. Offer something concrete, such as a free fee audit or a stockout-risk review, instead of asking for a call.

Frequently Asked Questions

How much does it cost to start selling with FBA?

The cost depends mostly on inventory. Beyond product cost, expect a Professional seller subscription, referral fees on each sale, FBA fulfillment fees, and storage fees. Check the current subscription price and fee schedule in Seller Central.

Do I need a Professional account for FBA?

Most FBA sellers use the Professional plan because it unlocks advertising, bulk tools, and more categories. Confirm the current plan terms in Seller Central.

Can I use FBA and ship orders myself?

Yes, but not for the same product in the same marketplace at the same time. Many sellers use FBA for fast movers and self-fulfillment for bulky or slow SKUs.

What is the biggest FBA fee to watch in 2027?

Fulfillment fees and the fuel surcharge are predictable. The ones that surprise sellers are aged inventory surcharges, low-inventory fees, and inbound defect fees, because they come from inventory planning and prep mistakes.

Is FBA still worth it in 2027?

For standard-size, fast-turning products with healthy margins, usually yes. For heavy, oversized, or low-margin items, compare it against self-fulfillment and a 3PL before deciding.

Takeaways

• FBA trades fees for Prime eligibility, convenience, and Amazon-run customer service.
• Verify every rate in Seller Central. Third-party fee guides often conflict.
• Model the 3.5 percent fuel surcharge as permanent in your margin math.
• Prevent aged inventory and low-inventory fees with a weekly restock review.
• Make your supplier responsible for correct labeling and prep.
