Use Amazon FBA to fulfill orders from Shopify, WooCommerce, eBay, and other platforms. Learn how multi-channel fulfillment works and when it makes sense.

What Is Selling on Amazon?

Selling on Amazon means putting your products in front of the world's largest online marketplace—with over 300 million active users and billions in daily transaction volume. Whether you're a small individual seller listing a few items or a growing brand with thousands of SKUs, Amazon's infrastructure can handle your fulfillment needs through its FBA (Fulfilled by Amazon) program. The platform operates on a competitive marketplace model where your listings compete directly with other sellers, including Amazon itself, for the coveted Buy Box position that drives the majority of sales. Understanding how Amazon's algorithm works, what fees you'll pay, and how to optimize your listings are the three pillars of success on this platform in 2026.

Amazon FBA vs FBM: Choosing Your Fulfillment Strategy

Your fulfillment choice shapes your entire Amazon business. FBA (Fulfilled by Amazon) offloads inventory storage, picking, packing, and shipping to Amazon's warehouses in exchange for fees—but gains you Prime eligibility and Buy Box advantage. FBM (Fulfilled by Merchant) keeps logistics in-house: you store inventory yourself and ship directly to customers, saving on FBA fees but losing the Prime badge and handling all customer service. Hybrid approaches work too—store fast-moving items in FBA while fulfilling slower movers yourself. The best strategy depends on your product weight, storage space availability, and desired level of hands-on involvement.

Amazon Fee Structure in 2026

Amazon charges multiple fee types that stack up quickly. Referral fees range from 6% to 17% depending on category (electronics at 8%, clothing at 17%). FBA fulfillment fees add $3.22-$6.50 per standard unit, plus $0.78 per cubic foot for storage (January-September), doubling to $2.40 in the holiday season (October-December). Professional sellers pay a flat $39.99/month subscription while Individual sellers pay $0.99 per item sold. Add in costs for advertising, returns processing, and potential storage excess fees, and effective margins can be much thinner than advertised. Always use the FBA revenue calculator before committing to inventory.

How to Win the Buy Box

The Amazon Buy Box drives roughly 90% of all sales, so winning it is critical. Amazon awards the Buy Box to sellers based on price, fulfillment method (FBA sellers get priority), seller rating, shipping time, and stock availability. Maintain a seller rating above 95%, keep your prices competitive (within 5% of the lowest offer), ensure FBA fulfillment for Prime eligibility, and maintain adequate stock levels. Avoid policy violations and respond to customer messages within 24 hours. Price increases to improve margins can cost you the Buy Box—test changes incrementally.
