Amazon Warehousing and Distribution (AWD) is Amazon's bulk storage and distribution service. You send inventory to AWD in bulk, it is stored at a low monthly rate, and AWD automatically replenishes your FBA inventory as it sells down. It sits upstream of FBA in your supply chain, acting as a reserve that feeds the fulfillment network.
Andrew Erickson is the founder of Inventory Hero. He has spent years working with Amazon FBA sellers on demand forecasting, restock planning, and the cash flow side of running a private-label brand. Inventory Hero exists because every spreadsheet-based inventory system he tried eventually broke — usually right before Q4.
You ship bulk inventory into AWD. AWD stores it cheaply, then automatically creates and sends replenishment shipments to FBA based on your sales, so your FBA stock stays topped up without you manually creating inbound shipments. For eligible sellers it can also distribute to other channels. You pay for storage, processing, and transportation to FBA.
Is Amazon AWD cheaper than FBA for long-term storage?
Yes, for holding inventory, AWD storage is materially cheaper per cubic foot than FBA and, unlike FBA, does not spike during the Oct to Dec peak season. The trade is that AWD adds transportation and processing costs to move units to FBA, and AWD units are not immediately fulfillable. For bulk reserve and seasonal stock you will not sell for a while, AWD is usually the cheaper home; for the stock selling this month, FBA is where it needs to be.
Is Amazon AWD worth it?
AWD is worth it if you carry bulk reserve, seasonal, or slow-and-steady inventory that would otherwise rack up FBA storage and aged-inventory surcharges, or if you keep hitting FBA restock limits. It is less useful if you are small, turn inventory quickly, and your entire stock comfortably fits in FBA. It is a reserve tier, not a replacement for FBA.

Amazon AWD and FBA are not an either/or choice. AWD (Amazon Warehousing and Distribution) is low-cost bulk storage that sits upstream of FBA and automatically replenishes it; FBA is the fulfillment network that picks, packs, and ships orders to customers. The short version: use FBA for the inventory you will sell soon, and AWD for bulk reserve and seasonal stock you want to hold cheaply without crowding your FBA allocation. Below is how the two differ, the storage cost math, and when to lean on each.
FBA is fulfillment. Inventory in FBA is fulfillable: it can ship to a customer the moment an order comes in, with the Prime badge attached. You pay for that with per-unit fulfillment fees and monthly storage fees that climb during peak season.
AWD is upstream storage and distribution. Inventory in AWD is not directly fulfillable to customers. Instead, AWD holds it in bulk at a low rate and automatically sends replenishment shipments into FBA as your sellable stock draws down.
Amazon Warehousing and Distribution (AWD)
AWD is Amazon's bulk storage service that sits upstream of FBA. You send inventory in bulk, store it at a low flat monthly rate, and AWD automatically replenishes your FBA inventory as it sells, so your fulfillable stock stays topped up without manual inbound shipments.
The two are designed to be a pipeline, not a pick-one decision. You send bulk inventory into AWD. AWD stores it cheaply and, based on your sales velocity, automatically creates replenishment shipments into FBA so your fulfillable stock stays topped up. You stop manually building FBA inbound shipments for those SKUs, and your reserve sits in cheaper storage until it is needed.
That pipeline is most valuable when you buy in bulk (to hit supplier minimums or lower unit costs) but do not want all of it sitting in expensive FBA storage, or when you build seasonal inventory ahead of Q4 and want it staged cheaply until demand arrives.
This is where AWD earns its place. FBA monthly storage is priced per cubic foot and is seasonal. For standard-size items it runs about $0.87 per cubic foot in the off-peak months (January to September) and jumps to about $2.40 per cubic foot during the October to December peak.1 So a pallet of slow-moving stock sitting in FBA through Q4 is paying the most expensive storage of the year at the exact time you may not be selling it fast.
AWD storage is billed at a lower, flat monthly rate, around $0.48 per cubic foot in most regions (about $0.57 on the West coast), with no Q4 peak surcharge.2 But the honest comparison has to include the cost of moving that stock into FBA, because AWD is a reserve, not a fulfillment center. Hold 10 cubic feet of reserve through the October to December peak and then send it to FBA:
10 cu ft, held Oct to Dec then sent to FBA
FBA (peak)
AWD
Storage, 3 months
about $72 ($2.40/cu ft)
about $14 ($0.48/cu ft)
Transport into FBA
none (already there)
about $14 ($1.40/cu ft)

$1.40 per box, each way
AWD is meaningfully cheaper for holding, and it avoids the aged-inventory surcharges FBA piles onto stock that sits too long. But the transport and processing fees narrow the gap, which is the whole point: AWD wins when units sit a while before selling, and FBA wins when they turn quickly and you would have paid to move them twice. On a thin-margin SKU, run the move costs before assuming AWD is cheaper.
AWD stock is also not instantly fulfillable; replenishment into FBA takes several business days, so you still need FBA safety stock to cover the gap.
Yes, and this is an underrated reason to use it. FBA caps how much inventory you can send in, governed by your restock limits and capacity, which Amazon sets based on your inventory performance and IPI score. AWD inventory does not count against those FBA limits.
So if you keep bumping into restock limits, or you want to stage a large seasonal build without it consuming your FBA capacity, AWD gives you a place to hold the overflow that still feeds FBA automatically. It is a pressure-release valve for the capacity constraints that otherwise force you into awkward, frequent small shipments.
Run each SKU through a simple question: how soon will this stock sell?
Selling this month, turns quickly: keep it in FBA. The storage premium is worth it because the units are not sitting long and they need to be fulfillable.
Bulk reserve, seasonal, or slow-and-steady: stage it in AWD. You hold it cheaply, avoid the Q4 peak surcharge and aged-inventory fees, and let AWD refill FBA as it sells.
You keep hitting FBA restock limits: use AWD to hold what FBA will not accept yet.
Small catalog, fast turns, everything fits in FBA comfortably: you probably do not need AWD yet. As a rough signal, if your peak FBA storage bill is under a few hundred dollars a month, the overhead of running an AWD pipeline likely outweighs the savings. It is a reserve tier, and you have nothing to reserve.
One practical gate: AWD is built for bulk. You send inventory in by the pallet or in LTL freight quantities, not the small parcel shipments a newer seller might use, so it fits sellers who are already buying and shipping in volume.
The decision is the same shape as our FBA vs FBM comparison: match each SKU to the cheapest home that still gets it where it needs to be, on time. AWD versus FBA is the storage version of that question; FBA versus FBM is the fulfillment version.
Either way, the input you cannot skip is knowing how fast each SKU sells and how much cover you are holding across every location. Inventory Hero pulls your real sales velocity and on-hand inventory across FBA, AWD, and your own warehouse, and tells you what to reorder and when, so the pipeline stays full without overstuffing it.
