Send to Amazon is the shipment-creation workflow inside Seller Central under Inventory > Shipments, and it replaces the older multi-screen FBA shipping process with one guided path. It cuts the steps needed to move inventory into the FBA network, lets you save case-pack templates for repeat shipments, and bundles carrier selection right into the same screen. Start at Send to Amazon in Seller Central, choose the SKUs you want to ship, and the system walks you through the rest.

TL;DR:

• Properly verifying box weights and dimensions before confirming shipments prevents delays caused by mismatched labels or content errors.
• Using case-pack templates that include SKU, units per box, and packing requirements helps speed up receiving and reduce rework.
• Timing shipments during peak periods requires building in extra lead time for longer queues and potential carrier scheduling delays.
• Shipping part of inventory as palletized freight or small parcels can reduce costs and improve tracking, but mixing modes can save money and optimize logistics.
• Ensuring pallets meet size, weight, and loading dock requirements avoids costly rejections and delivery setbacks at the fulfillment centers.

How Does the Send to Amazon Workflow Actually Work?

The process runs through five phases, and skipping ahead in any of them tends to cause the label mismatches and rejected boxes sellers complain about most.

1. Choose inventory to send. Pick your ship-from address, destination marketplace, and the SKUs you already have listed as FBA. Amazon assigns fulfillment centers based on your catalog and location, so this step locks in more downstream decisions than most sellers expect.
2. Pack individual units. Decide whether each box holds a single SKU or a mix of several. Case-pack templates let you save this configuration once and reuse it on every future shipment for that product, and Amazon allows you to pack before you even open a new shipment, which speeds up repeat orders considerably.
3. Confirm shipping. Set your estimated ship date, pick a shipping mode (small parcel or freight), and choose a carrier. Seller Central shows estimated costs at this stage, which is your last real checkpoint before committing to a rate.
4. Print box labels. Labels need to go on before the carrier picks up, and the box content information you enter here (unit counts, weights, dimensions) has to match what is physically inside. Mismatches at this step are the single biggest cause of receiving delays.
5. Confirm carrier and pallet info, then print pallet labels. For palletized freight, you will enter pallet count, dimensions, and weight, then print pallet labels that go on each pallet face before pickup.

Amazon’s own documentation on Send to Amazon covers each screen in more detail, but the sequence above is what determines whether your shipment sails through receiving or gets flagged for exceptions.

Which Shipping Mode Fits Your Shipment?

Small Parcel Delivery (SPD) works for individual boxes within standard carrier weight and dimensional limits, and it comes with per-box tracking that updates automatically once a carrier scans it. LTL and FTL apply once you are shipping palletized freight, and Amazon requires specific pallet dimensions, weight caps, and often a loading dock or lift-gate on your end for pickup.

• SPD suits smaller, frequent shipments where per-box tracking matters more than freight economics.
• LTL/FTL fits bulk restocks, and pallet specs and dock readiness determine whether the carrier can even complete pickup.
• Amazon partnered carriers post charges directly to your Payments account and handle tracking automatically, trading some flexibility in carrier choice for less administrative overhead.
• Third-party carriers give you more control over rates and pickup windows but require you to enter tracking or PRO/BOL numbers manually.

Multi-mode shipments make sense when part of your inventory ships as loose cartons and the rest as palletized bulk. Splitting the shipment by mode rather than forcing everything into one carrier type usually saves money.

Pro Tip: Sellers can cancel partnered-carrier SPD charges within 24 hours of accepting, and LTL/FTL charges within one hour. If a rate looks off, act inside that window before it locks in.

Building Case-Pack Templates That Actually Speed Things Up

A good template does more than save you a few clicks. It should include the SKU, units per box, box weight, box dimensions, and any prep or labeling rules specific to that product, like poly bagging or bubble wrap requirements.

• Build one template per packing configuration, not one per SKU, since many products share identical box dimensions and unit counts.
• For mixed-SKU boxes, confirm unit-level prep before sealing, since Amazon expects accurate per-unit identification inside a shared carton.
• Print labels using a thermal printer where possible, since laser-printed labels on glossy stock scan poorly at receiving docks.
• Place labels flat on the largest visible surface, away from seams or tape, so scanners catch them on the first pass.

Accurate box content information speeds Amazon’s receiving process and cuts down on the repacks that otherwise delay your inventory going live.

Timing Your Shipments to Avoid Stockouts

Send to Amazon keeps your inventory data synchronized in near real time once a shipment is confirmed, which matters because Amazon’s own forecasting tools lean on that data to flag reorder points.

1. Build in extra lead time during Q4 and other peak periods, since receiving queues at fulfillment centers lengthen when shipment volume spikes.
2. Expect SPD shipments to reach available status faster than LTL freight, which often waits longer for dock appointments.
3. Factor partnered-carrier scheduling into your buffer, since booking windows can push your actual pickup date out several days from your estimate.
4. Set reorder triggers at least one full receiving cycle before you expect to run out, not at the point you actually hit zero stock.

Fixing the Most Common Send to Amazon Problems

Amazon frequently splits one shipment across multiple fulfillment centers based on capacity and your ship-from location, and there is no way to force a single-destination shipment for most sellers. Treat each split as its own shipment with its own labels and tracking.

• Reprint labels immediately if box content and physical labels do not match. A rejected box costs more time than a fresh label run.
• If tracking never updates for a partnered-carrier shipment, check the shipment confirmation email before assuming the carrier lost it.
• Before contacting seller support, gather your shipment ID, tracking or PRO number, box labels, and photos of the pallet or carton as shipped.
• For consistently missing scans, escalate directly with the carrier first since Amazon’s system often just mirrors carrier-reported data.

What a 3PL Sees That Amazon’s Docs Don’t Cover

Amazon’s help pages explain the software. They don’t cover the loading dock. Pallets that arrive underbuilt or overweight for the carrier’s lift-gate capacity get bounced back, and that single mistake can add days to an inbound shipment that otherwise had clean paperwork.

• Stage pallets to exact height and weight specs before the pickup window opens, not the morning of.
• Run denied-party screening on new suppliers and freight partners, since a flagged shipment can sit on hold for days with no clear resolution path.
• Verify every case-pack template field against the physical carton before confirming a shipment, since 3PLs handling FBA prep at scale routinely catch mismatches sellers miss on their own.
• Consider outsourcing inbound prep once shipment volume outpaces the time your team has to build pallets and check labels correctly.

What I’ve Learned Watching Inbound Shipments Go Wrong

Build your case-pack templates before you need them, and verify box weights against the template before you hit confirm on step two. Nearly every delay traces back to a number entered in a hurry, not a carrier problem.

FAQ

How Do I Send Inventory to an Amazon Fulfillment Center?

Log into Seller Central, go to Inventory > Shipments > Send to Amazon, choose your SKUs, pack your boxes, confirm a shipping mode and carrier, then print and apply box or pallet labels before pickup.

Is FBA or FBM Better for New Sellers?

It depends on margin and volume: FBA suits sellers who want Amazon to handle storage, packing, and returns, while FBM fits lower-volume or oversized items where fulfillment fees would eat too much profit.

Is FBA Still Profitable in 2026?

FBA remains viable for sellers who manage inbound costs carefully, since fees vary heavily by product size, weight, and season, and profitability comes down to controlling those shipping and storage costs rather than any blanket guarantee.

Can I Make $1,000 a Month Selling on Amazon?

Many sellers reach that level with a focused product line and consistent inventory flow, but results vary widely based on niche, pricing, and how well you manage the Send to Amazon shipment process to avoid stockouts.

What Happens If My Box Labels Don’t Match the Contents?

Amazon’s receiving team may reject or hold the box until the content information matches, so reprinting accurate labels before pickup is far faster than fixing a rejection after the shipment arrives.
