Key takeaways:
- Choose your products carefully. Research demand, competition, costs, and profitability before investing in inventory.
- Pay close attention to 2026 FBA fees. Account for fulfillment, storage, referral fees, the 3.5% fuel surcharge, and the 181-day aged inventory threshold.
- Follow Amazon FBA packaging and labeling requirements and verify product dimensions to avoid unexpected fees.
- FBA offers convenience and scalability, while FBM may be more cost-effective for bulky, slow-moving, or low-margin products.
Monitor inventory, fees, advertising, sales velocity, and SKU-level margins before scaling your Amazon business.
Fulfillment by Amazon (FBA) can simplify fulfillment because Amazon stores, picks, packs, ships, and provides customer service for eligible orders.
For US beginners, learning how to start selling on Amazon in 2026 requires more than simply sending products to Amazon. Sellers need to understand product research, FBA fees, inventory requirements, product-size tiers, aged inventory costs, and the difference between FBA and Fulfillment by Merchant (FBM).
This ePlaybooks guide explains how to start selling on Amazon FBA step by step, including the major 2026 fee changes you should understand before sending your first shipment.
What is Amazon FBA?
Amazon FBA is Amazon's fulfillment service that lets sellers outsource inventory storage, order fulfillment, customer service, and returns to Amazon. Instead of shipping each order yourself, you send inventory to Amazon fulfillment centers, and Amazon handles eligible customer orders on your behalf.
With FBA, Amazon can:
- Store your inventory in its fulfillment network.
- Pick and pack products after customers place orders.
- Ship eligible orders to customers.
- Handle customer service for FBA orders.
- Process eligible returns.
- Make eligible products available for Prime fulfillment benefits.
This makes FBA particularly useful for beginners who want to focus on product selection, branding, marketing, and sales instead of managing every individual shipment.
FBA is different from Fulfillment by Merchant (FBM), where the seller remains responsible for storing inventory, packing orders, shipping products, and managing much of the fulfillment operation.
How much does Amazon FBA cost in 2027?
Amazon FBA costs depend on your selling plan, product category, product size and weight, fulfillment, storage, referral fees, and other services. Amazon's 2026 US FBA changes took effect primarily on January 15, 2026, with Amazon reporting an average FBA fee increase of about $0.08 per unit. Understanding Amazon seller fees before purchasing inventory is essential because these costs directly affect your profit margin.
Amazon seller account fees
Referral fees are separate from these subscription charges and vary by product category.
April 2026 fuel and logistics surcharge
Since April 17, 2026, Amazon applies a 3.5% fuel and logistics-related surcharge to US FBA fulfillment fees. The surcharge is calculated on the fulfillment fee, not on the product's selling price. Amazon says the average impact is approximately $0.17 per US FBA unit, although the actual amount varies by product. For example:
The new small bulky size tier
Small Bulky is a new US FBA size tier introduced on January 15, 2026, to separate smaller bulky products from Large Bulky products. A Small Bulky item can weigh up to 50 lb and generally cannot exceed 37 inches on its longest side, 28 inches on its median side, 20 inches on its shortest side, or 130 inches in length plus girth.
For many sellers, this change can lower fulfillment costs compared with the old Large Bulky classification. However, packaging still matters because Amazon determines the size tier using the packaged product's recorded dimensions and shipping weight.
FBA storage fees in 2026
US FBA storage costs are $0.78 per cubic foot for standard-size products from January through September and $2.40 per cubic foot from October through December. Oversize inventory is $0.56 per cubic foot from January to September and $1.40 per cubic foot from October to December.
Because Q4 storage rates are substantially higher, beginners should avoid sending excessive inventory into Amazon before the holiday period unless demand forecasts support it.
Amazon's 181- day aged inventory threshold
Amazon's 2026 aged inventory surcharge begins when inventory reaches 181 days in storage, making inventory turnover an important part of FBA profitability. The updated schedule introduced additional age bands beginning January 16, 2026.
This means beginners should not treat storage as an unlimited warehouse. Slow-moving inventory can accumulate monthly storage charges and eventually trigger aged inventory surcharges.
6 steps to start selling with Amazon FBA
Here’s a step-by-step guide to help you sell with Fulfillment by Amazon:
- Choose products to sell on Amazon
- Find a supplier
- Open your Amazon Seller account and set up FBA
- Create product listings
- Arrange products for shipment
- Ship products to Amazon
Step 1: Choose products to sell on Amazon
If you are just starting on Amazon, the first step is to choose a product. To choose a product, start by creating a list of some product categories. Perhaps the top five categories you are interested in. Next, carry out product research. This is important because though you might be passionate about selling a product, it might not be in demand. This can affect the profitability of your business.
Use platforms like Google to check for products that customers are searching for. You can also carry out keyword research or go through Amazon’s bestseller pages to get deeper insights into what products are most profitable.
Step 2: Find a supplier
After thorough product research, the next step is to find suppliers for your selected product. You can go through suppliers' directories on trusted sites or look out for local manufacturers making quality products you can sell through your Amazon account.
Alternatively, you can approach successful businesses on Amazon and ask to get a list of their suppliers. Keep shipping fees and delivery time in mind to ensure you get your inventory quickly and most cost-effectively.
Step 3: Open your Amazon Seller account and set up FBA
Create your Amazon Seller account and choose the selling plan that matches your expected sales volume. For most serious new businesses, the Professional plan is the more practical option because it provides access to additional selling tools and avoids the $0.99 per-item Individual-plan charge.
Amazon requires seller verification information, which can include identity, business, tax, banking, and payment information.
Once your account is approved, use Seller Central to create or manage your FBA inventory.
Step 4: Create product listings
To create your product listings, go to your Amazon Seller Central account and click on Add Product located at the inventory drop-down menu. Then, create a new product listing and select a product category. Add each product title, description, brand name, price, and product code. Lastly, save all entries and click Finish. Remember to optimize your listings using relevant keywords, high-quality images, and other online marketing strategies to drive traffic and boost sales.
Step 5: Arrange products for shipment
Understanding Amazon FBA packaging and labeling requirements is essential before sending inventory to Amazon. Prepare every unit according to Amazon's current FBA packaging, labeling, and product-preparation requirements before creating your shipment. Keep in mind that your packaging also affects your FBA economics. A small dimensional change can move a product into a different size tier, potentially increasing fulfillment costs.
Step 6: Ship products to Amazon
Shipping inventory to Amazon FBA warehouses requires creating an FBA shipment in Seller Central, following Amazon's shipment instructions, and sending your prepared inventory to the assigned fulfillment locations.
Amazon determines the fulfillment-center destinations and provides the shipment workflow in Seller Central. Before shipping, verify your unit quantities, SKU and FNSKU information, product dimensions, packaging, labels, carton contents, and shipment details.
Once Amazon receives and processes your inventory, your products can become available for sale.
FBA vs. FBM: which is better for beginners?
FBA is usually the easier option for beginners who want Amazon to handle fulfillment, but FBM can become more attractive for bulky, slow-moving, low-margin, or operationally efficient products.
FBA gives sellers access to Amazon's fulfillment infrastructure but adds fulfillment and storage costs. FBM gives sellers more control over fulfillment but requires them to manage warehousing, shipping, customer service, and returns.
Has the FBA vs. FBM break-even point changed in 2026?
Yes, the economics have shifted toward closer comparison because 2026 FBA fulfillment costs include the January fee changes and the additional 3.5% fuel and logistics surcharge. Amazon says its 2026 FBA fees increased by an average of $0.08 per unit, while the April surcharge adds another 3.5% to fulfillment fees. There is no single sales-volume number at which FBA becomes cheaper than FBM. The break-even point depends on factors like product size and weight, selling price, FBA fulfillment fee, storage requirements, monthly sales volume, your warehouse or 3PL cost, pick-and-pack costs, shipping rates, customer service costs, return rates, etc.
As an Amazon seller, you want to calculate the FBA-vs.-FBM break-even point at the SKU level rather than assuming FBA is always cheaper.
For example, a small, fast-moving product may remain highly suitable for FBA because Amazon's fulfillment network provides operational efficiencies. A large or slow-moving product may increasingly favor FBM if the seller can fulfill orders efficiently and avoid Amazon's storage and aged-inventory costs.
How to maximize sales using Amazon FBA
Fulfillment by Amazon is an incredibly beneficial service that takes away the burden of order fulfillment and customer service from your shoulders. However, you want to make sure you maximize sales by ensuring the benefits outweigh the costs.
If you want to know how to increase your conversion rate on Amazon FBA and grow company revenue, here are a few tips that can help you:
- Carefully select your products: When selecting products, consider products with high demand to ensure that they sell quickly and keep your inventory moving. A product with a low ranking could mean that your inventory would sell more slowly, attracting increased storage fees that could eat into your profits.
- Optimize your product page: Your product page is the first thing your customers will interact with. An optimized product page will drive traffic and increase your conversion rate. You want to make sure you use relevant keywords that customers are searching for to get your page seen by customers. Add them to your product title and product descriptions. Add high-quality images and videos that display your product dimensions. Throw in some lifestyle images to give customers a good picture of what using your product is like. Lastly, keep your product page free of any spelling or grammatical errors.
- Engage with your customers: Excellent customer service is an effective strategy that attracts customers and builds customer loyalty. A customer will buy from you repeatedly if they get their questions and complaints answered as promptly as possible.
- Get good reviews: Getting good product reviews and ratings dispels objections, increases buyer trust, and improves page rankings. As a new Amazon seller, getting reviews doesn't have to be difficult. Avoid trying to pretend that you are a global brand. Simply engage with your customers in a personal way. You can use the “Request a Review” button on Amazon, or you can use your social media or email to request a review from your customers after every purchase.
- Use FBA export: At no cost, you can get your products to customers in over 100 countries using FBA export. Amazon selects the products that are eligible for FBA exports, fulfills your international orders, handles import duty, and ships your product to the international buyer. The customs duty and shipping costs fall on the buyer, so this means no extra cost. To enroll in FBA export, all you need to do is go to the FBA settings and enable FBA export.
Conclusion
Starting with Amazon FBA can be a practical way for US beginners to build an ecommerce business without managing every part of order fulfillment themselves. Amazon handles much of the physical fulfillment operation, allowing sellers to focus on product research, branding, marketing, and growth.
But FBA is not automatically profitable. Before placing your first inventory order, calculate your landed cost, Amazon fees, storage expenses, advertising budget, expected sales velocity, and FBA-versus-FBM break-even point. You can start with controlled inventory, monitor sales, and scale if your product can scale profitably.
If you need ongoing support with Seller Central operations, ePlaybooks' Amazon account management services can help with day-to-day account management, listing optimization, inventory coordination, and other aspects of managing an Amazon business.
