Selling on Amazon means opening a seller account, choosing how you’ll source products, deciding how orders get fulfilled, and managing fees that eat into your margins at every stage. The platform gives you access to hundreds of millions of active shoppers, but profitability depends on understanding the mechanics before you list your first product. Here’s how the entire process works.
Choose Your Seller Account Type
Amazon offers two account tiers. The Individual plan costs $0.99 per item sold and makes sense if you’re testing the waters with a small number of products. The Professional plan costs $39.99 per month regardless of how many items you sell, and it unlocks advertising tools, bulk listing features, and eligibility for the Buy Box (the “Add to Cart” button that captures most sales on any given listing). If you plan to sell more than about 40 items per month, the Professional plan pays for itself.
Setting up your account requires a government-issued ID, a bank account for deposits, a credit card for charges, and tax information. Amazon will verify your identity, which can take a few days. Once approved, you can start listing products immediately.
Pick a Sourcing Model
How you get products to sell shapes everything else about your business: startup costs, profit margins, risk level, and how much time you’ll spend. Three models dominate Amazon selling.
Retail and Online Arbitrage
You buy discounted or underpriced products from other retailers and resell them on Amazon at a higher price. There’s no product development, no manufacturer negotiations, and no branding work. You’re simply exploiting price gaps. Startup costs are low, often $500 to $1,000, and you can test products with minimal risk. The tradeoff is thinner margins, typically 10 to 30 percent per product, and the constant need to hunt for new deals. Inventory supply is unpredictable since it depends on whatever sales and clearance events you can find.
Wholesale
You buy established branded products in bulk directly from manufacturers or authorized distributors, then resell them on Amazon. Margins fall between arbitrage and private label, and you benefit from selling products with existing demand. The challenge is getting approved by brands willing to let you distribute on Amazon, and you’ll often compete with other authorized resellers on the same listing.
Private Label
You work with a manufacturer (often overseas) to produce a product under your own brand name. This gives you full control over pricing, packaging, and marketing. Profit margins are higher, often 30 to 50 percent, because you’re not competing on someone else’s listing. But startup costs are significantly larger, usually $2,000 to $5,000 or more for initial inventory, branding, and product photography. The risk is real: you’re investing in bulk inventory before you know whether customers will buy it.
Understand Referral Fees
Every item sold on Amazon incurs a referral fee, which is a percentage of the sale price that Amazon keeps. The rate varies by product category but typically falls between 8 and 15 percent. Electronics tend to sit at the lower end, while clothing and accessories are at the higher end. This fee applies regardless of how you fulfill orders, so it’s the baseline cost of using the platform. Factor it into your pricing from day one.
Decide How Orders Get Fulfilled
Fulfillment is the single biggest operational decision you’ll make. Amazon gives you two paths, and each carries distinct cost and control implications.
Fulfillment by Amazon (FBA)
You ship your inventory to Amazon’s warehouses, and they handle storage, picking, packing, shipping, returns, and customer service. Your listings automatically get the Prime badge, which matters enormously. Prime members convert at an estimated 20 to 30 percent higher rate than non-Prime offers, and Amazon’s algorithm favors FBA listings when deciding which seller wins the Buy Box.
The cost structure, however, has grown complex. You’ll pay fulfillment fees per unit (varying by size and weight), monthly storage fees ($0.78 per cubic foot from January through September, jumping to $2.40 per cubic foot during October through December), and potentially several surcharges. Inventory sitting longer than 12 months triggers aged inventory fees of $0.30 per unit per month for items 12 to 15 months old, rising to $0.35 per unit for items older than 15 months. If your inventory levels dip below 28 days of supply, you’ll face low-inventory-level fees. There are also inbound placement fees when you ship inventory to Amazon’s network.
A few recent changes are worth noting. Amazon discontinued all FBA prep services on January 1, 2026, meaning every unit you send must arrive at the fulfillment center fully compliant: labeled, bagged, and bundled. If Amazon loses or damages your inventory, reimbursement is now based on your manufacturing cost, not your retail price. And inbound defect fees for mislabeled or improperly packaged shipments can run $0.32 to $1.74 per standard unit, or up to $5.72 for bulky items.
Fulfillment by Merchant (FBM)
You handle everything yourself: storing inventory, packing orders, shipping, processing returns, and responding to customer inquiries within Amazon’s required 24-hour window. You avoid all FBA fees, aged inventory surcharges, and inbound defect penalties. You also get branding control, with the ability to use custom packaging, insert cards, and create a branded unboxing experience.
The downside is visibility. Without the Prime badge, your listings convert at lower rates and face a disadvantage in Buy Box competition. FBM sellers typically need to undercut FBA prices by a few percentage points or beat delivery speed to stay competitive. Amazon increasingly expects one-to-two-day delivery even from FBM sellers, which means you’ll likely need strategically placed warehouses or a third-party logistics provider to keep up. Since February 2026, all FBM orders also require prepaid return labels, adding another cost to manage.
A third option, Seller Fulfilled Prime, lets you display the Prime badge while handling your own fulfillment. The requirements are steep: zero-day handling (orders placed before 2:00 PM on weekdays must ship same day), nationwide one-to-two-day delivery through Amazon-approved carriers, a minimum of 100 SFP packages per month, and an on-time delivery rate of at least 93.5 percent. You only get three trial attempts per calendar year.
Create Listings That Convert
Your product listing is your storefront. The title should include your primary keyword and the most important product attributes (brand, size, color, quantity) within Amazon’s character limits. Bullet points should focus on benefits, not just features. If you’re selling a kitchen knife, “stays sharp through 500 uses” tells a shopper more than “stainless steel blade.” Use all available image slots with high-resolution photos showing the product from multiple angles, in use, and next to a reference object for scale.
Backend search terms, which are invisible to shoppers but indexed by Amazon’s search algorithm, give you space to include synonyms, alternate spellings, and related keywords you didn’t fit into your visible listing. Fill these out completely.
Register Your Brand
If you’re selling private label products, enrolling in Amazon Brand Registry is close to essential. You need either an active registered trademark or a pending trademark application. Once enrolled, you unlock several tools that generic sellers can’t access: A+ Content (enhanced product descriptions with images and comparison charts), a dedicated Brand Store (your own multi-page storefront on Amazon), Sponsored Brands ads, and Brand Analytics with detailed search and purchase data.
Brand Registry also protects your listings from hijackers and unauthorized sellers who might alter your product detail pages or undercut you with counterfeit goods. You get faster issue resolution when problems arise with Amazon support. Starting in spring 2026, Brand Registry is required if you want to use manufacturer UPCs with FBA. Without it, you’ll need to apply Amazon FNSKU labels to every single unit.
Drive Traffic With Advertising
Organic search ranking on Amazon is heavily influenced by sales velocity, which creates a chicken-and-egg problem for new listings. Amazon’s pay-per-click advertising platform helps you break through. Sponsored Products ads appear in search results and on product pages, and they’re where most sellers start. You bid on keywords, and you only pay when a shopper clicks.
Start with automatic campaigns, where Amazon chooses which search terms trigger your ads based on your listing content. After a couple of weeks, review the search term report to see which keywords actually generated sales, then create manual campaigns targeting those specific terms. A common starting budget is $10 to $30 per day, adjusted based on your advertising cost of sale (the percentage of ad-attributed revenue you’re spending on ads). Most sellers aim to keep this below 25 to 30 percent, though early launches may run higher as you build ranking.
Manage Your Account Health
Amazon monitors seller performance continuously and will suspend accounts that fall below its thresholds. The metrics that matter most are your order defect rate (which includes negative feedback, A-to-Z Guarantee claims, and chargebacks), your late shipment rate (for FBM sellers), and your pre-fulfillment cancel rate. Keep your order defect rate below 1 percent, late shipment rate below 4 percent, and cancellation rate below 2.5 percent.
Respond to customer messages within 24 hours, resolve returns promptly, and monitor your account health dashboard in Seller Central regularly. If a metric slips, Amazon sends warnings before suspending, but reinstatement requires submitting a plan of action explaining the root cause and the steps you’ve taken to fix it. Prevention is far easier than appeals.
Calculate Your True Margins
Many new sellers underestimate costs because they only account for product cost and the referral fee. A realistic profit calculation for an FBA seller includes the product cost, shipping to Amazon’s warehouse, inbound placement fees, FBA fulfillment fees per unit, monthly storage fees, referral fees (8 to 15 percent of the sale price), advertising spend, and returns (which happen at higher rates in some categories like clothing). For FBM sellers, substitute your own warehousing, packing materials, shipping costs, and customer service time for the FBA-specific fees.
Before committing to any product, run the numbers using Amazon’s Revenue Calculator (available in Seller Central) to estimate your per-unit profit. A product with a 50 percent gross margin on paper can easily drop to 10 percent or less after all Amazon-related costs. The sellers who succeed long-term are the ones who know their numbers before they place their first inventory order.
