Overview

Amazon’s logistics network moves products from sellers to shoppers in under two days for Prime members. Knowing how each stage—from inbound receipt to the final doorstep—functions enables new sellers to cut costs, avoid stockouts, and deliver a smoother buying experience.

Key Points

• Global fulfillment footprint — More than 175 fulfillment centers operate worldwide, each tailored for categories such as apparel, hazardous materials, or oversized goods.
• Three‑tier delivery chain — An order leaves a fulfillment center, passes through a regional sortation hub, and then moves to a local delivery station before reaching the customer.
• Prime‑speed advantage — Leveraging Amazon’s own air, ground, and last‑mile fleets makes two‑day delivery possible for Prime shoppers, lifting conversion rates by roughly 30 % on eligible listings.
• Centralized inbound shipping — The “Inventory Placement Service” lets sellers ship all units to a single inbound dock, after which Amazon reallocates stock across its network.
• Automated returns flow — Returned items are scanned, evaluated, and automatically routed to restocking, liquidation, or refurbishment without seller involvement.
• Algorithmic demand forecasting — Amazon’s predictive models suggest replenishment quantities, helping sellers balance inventory levels and prevent both excess stock and out‑of‑stock situations.

How the Amazon Supply Chain Works

1. Inbound shipment to a fulfillment center — A seller sending 300 silicone baking mats loads a pallet at a Midwest inbound dock; Amazon’s carrier network picks up the pallet, scans the bill of lading, and books a receiving appointment.
2. Receiving, labeling, and storage — Warehouse staff unload the pallet, confirm each SKU against the shipment manifest, and affix Amazon’s FNSKU barcodes. The mats are then placed on a high‑rack system in the non‑hazardous zone, with the warehouse management system logging the exact bin coordinates.
3. Order pick‑and‑pack — When a buyer orders two mats, the system directs a picker to the precise bin, pulls the items, and transports them to a packing station. The packer selects a box sized to the product, attaches a shipping label, and places the package on a conveyor for outbound processing.
