Overview

Amazon’s fulfillment network—commonly referred to as an Amazon Fulfillment Center—is a nationwide system of warehouses where sellers deposit inventory that Amazon then picks, packs, ships, and services on their behalf. The service, known as Fulfillment by Amazon (FBA), lets sellers concentrate on sourcing and marketing while Amazon handles logistics, returns, and customer support, a shift that can dramatically affect scalability and profit margins.

Key Points

• Centralized storage — Sellers send bulk shipments to a designated Amazon warehouse, where each unit is scanned, assigned a location code, and held until an order triggers removal, exemplified by a vendor moving 5,000 units of a fitness tracker to the Memphis, TN center.
• Automated order routing — Amazon’s algorithm automatically selects the nearest fulfillment center with available stock, cutting delivery windows to as little as one day; for instance, a buyer in Seattle receives a product shipped from the nearby Kent, WA facility instead of a distant East Coast hub.
• Multi‑channel fulfillment — FBA inventory can satisfy orders placed on external platforms such as Shopify or Walmart, allowing a single warehouse to serve both Amazon and off‑Amazon sales, as demonstrated by a cosmetics brand routing 300 daily Shopify orders through its Los Angeles fulfillment node.
• Returns processing — Returned items are inspected, restocked, or disposed of according to seller preferences, eliminating the need for sellers to manage reverse logistics; a seller of wooden toys saw 92 % of returns automatically returned to inventory after quality checks.
• Prime eligibility — Products stored in Amazon’s network automatically qualify for Prime two‑day shipping, boosting conversion rates; a study of 1,200 FBA listings showed a 23 % higher buy‑box win rate compared with non‑Prime equivalents.
• Fee transparency — Storage and fulfillment fees are displayed in Seller Central on a per‑cubic‑foot and per‑order basis, enabling sellers to forecast costs; a seasonal décor vendor incurred $0.75 per cubic foot for November storage and $2.50 per unit for standard‑size order fulfillment.
