Inbound at Amazon refers to the process of receiving, sorting, and storing inventory that arrives at a fulfillment center. If you’re searching this term, you’re likely either considering a warehouse job in Amazon’s inbound department or you’re a seller trying to understand how your products get into Amazon’s system. Both sides of inbound work together: sellers ship products to fulfillment centers, and inbound associates physically receive, scan, and stow those products so they’re ready to be picked, packed, and shipped to customers.
What Inbound Associates Do
Inbound is one of several departments inside an Amazon fulfillment center, and it handles everything that happens between a truck pulling up to the dock and products being placed on shelves or in bins. The work breaks down into a few core tasks.
Receiving is the first stage. Associates unload trucks, scan incoming shipments, and verify that what arrived matches what was expected. This can involve driving forklifts to move pallets off trailers or manually handling individual parcels. Items can weigh up to 50 pounds, and shifts typically run 10 hours.
Stowing comes next. Once products are checked in, stow associates place them into bins or onto shelves throughout the warehouse. You walk the floor with a scanner, assigning each item to a specific storage location so the system knows exactly where it lives. This is a physically demanding role since you’re on your feet and moving continuously for the full shift.
At the Tier 1 level (Amazon’s entry-level warehouse position), inbound work also includes inventory control tasks like checking for damaged goods, relabeling items, and resolving discrepancies when a scan doesn’t match what’s in the system. Dock work, where you’re stationed at the loading bay managing the flow of incoming deliveries, is another common inbound assignment.
How Inbound Differs From Outbound
Outbound is the other major department in a fulfillment center, and it handles everything after a customer places an order. Outbound associates pick items from shelves, pack them into shipping boxes, and send them out for delivery. Inbound is the mirror image: getting products into the building and onto those shelves in the first place. Both roles are physically similar, but inbound tends to involve more heavy lifting from truck unloads, while outbound involves more walking during the pick process.
How Sellers Send Inbound Shipments
If you sell through Fulfillment by Amazon (FBA), “inbound” is the entire process of getting your inventory from your warehouse or supplier into Amazon’s fulfillment centers. The system walks you through a multi-step workflow inside Seller Central.
You start by creating a shipping plan, specifying where your inventory is shipping from and which products you’re sending. You’ll set quantities, then decide who handles product preparation and labeling: you or Amazon (Amazon charges fees if they do it for you). After you submit the plan, Amazon reviews your items and presents packing options. You choose one, then provide box-level details like how many boxes you’re sending, what’s in each box, and the weight and dimensions of each one.
Amazon then offers placement and transportation options. Placement determines which fulfillment center or centers your inventory gets sent to. You can ship everything to a single location or split shipments across multiple warehouses. Shipping to fewer locations is simpler but may cost more through inbound placement fees. Once you confirm transportation, Amazon provides a delivery window, and you pack and ship your products.
Packing and Labeling Rules
Amazon enforces strict requirements for inbound shipments, and not following them can delay your inventory from being received or trigger defect fees.
Boxes must be at least 6 x 4 x 1 inches and weigh at least 1 pound. On the upper end, no box can exceed 25 inches on any side or weigh more than 50 pounds total, unless it contains a single oversized item. Items over 50 pounds need a “Team Lift” label on the top and sides. Items over 100 pounds need a “Mechanical Lift” label.
Every unit needs a scannable barcode. Amazon uses either the manufacturer barcode (like a UPC) or an Amazon-specific barcode called an FNSKU. The manufacturer barcode is the default, but if you switch to Amazon barcodes in your settings, you’ll need to apply FNSKU labels to every unit. Any existing barcodes on the outside of your shipping boxes that aren’t part of the shipment need to be removed, covered, or made unscannable so they don’t confuse the receiving process.
Each box in your shipment gets its own unique FBA Box ID label, printed from your shipping queue. These labels are typically 3 1/3 x 4 inches, though thermal printers can use a 4 x 6 format. Place both the FBA label and your carrier’s shipping label on a flat surface of the box so barcodes don’t wrap around edges or corners. If you’re shipping pallets, each pallet needs four FBA Pallet ID labels, one centered on each side.
Inbound Fees to Expect
Sending inventory to Amazon isn’t free beyond your own shipping costs. Inbound placement service fees apply when Amazon distributes your inventory across its warehouse network. The exact fee depends on item size, weight, and how many fulfillment centers you’re willing to ship to. Sending to more locations yourself generally reduces placement fees since Amazon doesn’t have to redistribute your stock internally.
Amazon also charges an inbound defect fee for shipping errors. If your shipment is misrouted, abandoned, or doesn’t match what you declared in your shipping plan, you’ll pay a penalty. Accurate box contents, correct labeling, and following the shipping plan closely are the simplest ways to avoid these charges.
What the Inbound Experience Looks Like Day to Day
For warehouse workers, inbound shifts are structured around rate targets. Amazon tracks how many items you receive or stow per hour, and you’re expected to maintain a consistent pace. The work is repetitive but straightforward once you learn the scanning systems and storage layout. Most new hires start in inbound or outbound and can eventually move into other roles like problem solving (handling damaged or misrouted items) or process assistance (supporting the team lead).
For sellers, inbound is a process you’ll repeat every time you restock inventory. The workflow gets faster once you’ve done it a few times, but each shipment still requires attention to labeling, box dimensions, and accurate item counts. Errors at the inbound stage ripple forward: if Amazon can’t scan or identify your products when they arrive, your inventory sits in limbo, and you may face fees or delays in getting your listings back in stock.
