The Complexity Behind a Simple Click

Each day, approximately 13 million orders are placed on Amazon.com, with each purchase setting off a remarkably complex and intricately structured fulfillment system designed to ensure that almost all deliveries reach their destinations swiftly and efficiently. Amazon's fulfillment system is notably more convoluted than many other logistics networks, including those of UPS, FedEx, or DHL. This complexity is a key component of Amazon's recipe for success, as the company aims to present a user-friendly, streamlined customer experience.

Who Fulfills Your Order?

Firstly, the journey of an Amazon package depends on whether Amazon or the seller is fulfilling the order. Around 25% of U.S. sales are fulfilled directly by sellers, with Amazon having no role in these specific transactions. These third-party sellers use their logistics providers such as UPS, FedEx, or the postal service. It's the 75% of orders fulfilled by Amazon that showcase the intricate fulfillment process.

Sorting the Sizes

Amazon's fulfillment centers are categorized into small sortable, large sortable, and large non-sortable items.

Small Sortable: Items smaller than 12x16x6 inches or 30x40x15 centimeters and weighing under 25 pounds or 11 kilograms.
Large Sortable: Larger items up to 60 pounds or 27 kilograms.

The smaller items are easier to automate, using tools like the Kiva robot, which brings entire mobile shelves to pickers, thus enhancing efficiency. Larger items require more manual handling and distinct processes, despite usually being housed under the same roof.

Predictive Stocking

Amazon employs predictive modeling to stock items closest to customers predicted to buy them. This logistics strategy ensures faster delivery times while efficiently managing inventory across various demographics and locales.

Large Non-Sortable Items

The third category, large non-sortable items, includes very large, typically heavyweight products. These are often managed through third-party logistics providers or specialized Amazon facilities dedicated to handling and shipping these items.

Regional Sortation Centers

From the fulfillment centers, packages are sent to regional sortation centers. In the Denver area, for example, packages are sorted by destination zip codes using automated robots. Subsequently, these sorted packages travel via various modes of transportation, including Amazon’s own cargo planes, trucks, or third-party services, depending on their final destination.

Amazon Air and Prime Delivery

Amazon Air operates with a growing fleet of cargo planes to expedite shipping, structured around two-day delivery rather than overnight. Unlike UPS and FedEx, which operate night-time flights for overnight services, Amazon runs daytime flights, offering flexibility in routing and enabling efficient order deliveries.

Delivery Paths

Amazon packages can take several delivery paths:

Amazon Logistics: Cover major urban and suburban areas.
USPS: Handles less populous and mid-sized locations.
UPS: Covers highly rural areas or where USPS and Amazon Logistics aren't feasible.

Overall Strategy

Amazon's fulfillment strategy is built on intricate, data-driven logistics networks and modern technology. This not only serves to maintain their competitive edge but also suggests potential future ventures into offering their logistics services independently.
