Amazon sellers managing high inventory volumes face a persistent tension. FBA storage fees climb during peak season. Restock limits tighten when you need space most. Inbound placement fees add cost and complexity. Running out of stock kills momentum. Carrying too much inventory in FBA warehouses drains margin.
Amazon Warehousing and Distribution (AWD) offers one answer to that tension. AWD is an upstream bulk storage layer that sits between your supplier and FBA. You send pallets of inventory to AWD facilities at a lower storage rate than FBA. Amazon holds that inventory and automatically replenishes your FBA stock as it sells. In theory, you reduce storage costs, avoid stockouts, and simplify inbound logistics.
But AWD is not a universal solution. It works well for some sellers and poorly for others. This guide explains what AWD does now in 2026, what it costs, how it compares with FBA-only or a 3PL, and when it makes sense for your business.
Amazon Warehousing and Distribution (AWD) is a third-party logistics service run by Amazon. It provides low-cost bulk storage and automatic replenishment into FBA. AWD is part of Amazon’s broader Supply Chain by Amazon suite, which also includes Amazon Global Logistics, Buy with Prime, and Multi-Channel Fulfillment.
AWD launched in late 2022 as an invite-only program for select FBA sellers. By 2026, it is available to most Amazon sellers and no longer positioned as an experiment.
Supply Chain by Amazon connects several logistics services into one end-to-end stack. AWD sits in the middle of that stack as the upstream storage node.
A typical flow looks like this:
You can also use AWD to distribute inventory to non-Amazon channels, including your own warehouse, a 3PL, wholesalers, or Walmart Fulfillment Services. That multi-channel capability is a newer emphasis in Amazon’s public positioning.
AWD, FBA, and Multi-Channel Fulfillment (MCF) serve different roles:
AWD stores bulk inventory and replenishes FBA or other destinations. It does not fulfill customer orders directly. You send full pallets or large case quantities. Storage rates are lower than FBA. Processing and transportation fees apply when inventory moves out of AWD.
FBA stores inventory close to customers and fulfills Prime orders with two-day (or faster) delivery. Storage rates are higher than AWD. You pay per-unit fulfillment fees. FBA inventory counts toward your restock limits.
MCF uses the FBA network to fulfill orders from other sales channels like Shopify, Walmart, or your own website. You can configure MCF to use Amazon-branded or blank packaging. MCF pulls from FBA inventory, not AWD inventory.
AWD and FBA work together. AWD reduces how much inventory you hold in FBA at any given time, which lowers your storage fees and helps you stay within restock limits.
You create an AWD shipment in Seller Central. Amazon assigns an AWD destination facility. You prepare your shipment according to Amazon’s requirements:
You can ship AWD inventory via your own carrier or use Amazon’s Partnered Carrier Program. You cannot ship AWD and FBA inventory on the same truckload.
Most AWD shipments move by LTL (less-than-truckload) or FTL (full truckload). Some sellers report being able to ship smaller quantities via parcel, but LTL is the standard method. Check current Seller Central guidance before your first shipment. Rules around shipment methods have changed since AWD launched.
Once your inventory arrives at AWD, Amazon’s algorithm decides when and how much to replenish into FBA. You do not manually trigger replenishment for most SKUs. Amazon monitors your sales velocity and FBA inventory levels, then transfers cases from AWD to FBA automatically.
You can view auto-replenishment orders in Seller Central. You can also set manual controls at the SKU level if you want to override the default behavior. For example, if you are running a promotion or preparing for a specific event, you can manually request a larger replenishment quantity.
Auto-replenishment aims to keep your FBA stock in the optimal range: enough to avoid stockouts, but not so much that you pay high storage fees or hit restock limits.
AWD can distribute inventory to destinations beyond FBA. Amazon calls this “off-Amazon bulk distribution.”
You can send AWD inventory to:
This capability matters if you sell on multiple channels and want to use AWD as a central inventory pool. Instead of splitting safety stock across several locations, you hold bulk inventory in AWD and push it out to each channel as needed.
Multi-channel distribution through AWD is still less common than FBA replenishment. Most sellers use AWD primarily to reduce FBA storage pressure, not to coordinate inventory across several sales channels.
AWD pricing has three main components: storage fees, processing fees, and transportation fees. The total cost depends on how much inventory you store, how long you store it, and whether you qualify for discount tiers.
AWD charges storage fees per cubic foot per month. Rates vary by region and discount tier.
Public rates as of early 2026:
West Coast Regions
Other Regions
These rates are lower than FBA storage fees, especially during peak season. FBA storage fees rise sharply in Q4. AWD storage fees do not include a holiday surcharge.
Storage is billed based on daily usage. If your inventory sits in AWD for half a month, you pay for half a month.
AWD charges a processing fee when inventory enters the facility and when it leaves. The public rate is $1.40 per box for inbound processing and $1.40 per box for outbound processing.
Processing fees cover handling, receiving, and loading activities. They are charged per box, not per unit or per cubic foot. If you ship one SKU per box and each box contains 24 units, you pay one $1.40 processing fee for that box on the way in and another $1.40 when it replenishes to FBA.
AWD charges a transportation fee when inventory moves from AWD to FBA or another destination. The public rate is $1.40/cu ft (base tier) or $1.26/cu ft (Amazon-managed tier).
Transportation fees depend on distance and cube. Longer hauls cost more. Denser products (more units per cubic foot) spread the transportation cost across more units, which improves your per-unit economics.
AWD storage fees are lower than FBA storage fees. But AWD adds processing and transportation fees that FBA does not charge separately.
Whether AWD saves you money depends on:
A 3PL comparison is more complex. Some 3PLs charge lower storage rates than AWD. Some charge higher rates but offer more flexibility, faster hands-on support, or custom services like kitting, bundling, or branded packaging. 3PL pricing also varies widely by location, volume commitment, and service level.
AWD beats a 3PL on cost if your product profile fits AWD’s structure and you value tight integration with FBA. A 3PL beats AWD if you need manual control, custom handling, multi-channel flexibility, or faster exception management.
Run a cost model before committing inventory to AWD. Compare your current all-in cost per unit (including FBA storage, inbound placement, and any 3PL fees) against the projected AWD cost per unit.
Key inputs for the model:
If your product has low cube, high velocity, and predictable demand, AWD is more likely to produce cost savings. If your product has high cube, low velocity, or unpredictable demand spikes, the AWD fees can outweigh the storage savings.
AWD storage rates are substantially lower than FBA storage rates. That gap widens during Q4 when FBA storage fees climb.
If you buy inventory in bulk to lock in better supplier pricing, AWD gives you a place to store that inventory without paying peak FBA storage fees.
AWD auto-replenishment reduces the risk of stockouts caused by FBA receiving delays or restock limit constraints. You hold a larger safety stock in AWD and let Amazon move inventory into FBA as needed.
This matters most for fast-moving SKUs where a stockout kills rank, loses the Buy Box, and disrupts ad campaigns.
Auto-replenishment removes some of the daily inventory planning work. You do not have to calculate restock quantities, create shipments, and monitor receiving windows as frequently. Amazon’s algorithm handles replenishment timing and quantities automatically.
This benefit is larger for sellers managing many SKUs. It is smaller for sellers who prefer manual control over replenishment timing.
Amazon’s inbound placement fee adds cost when you ship inventory to multiple FBA locations. AWD simplifies that flow. You send one large shipment to one AWD facility. AWD handles distribution into the FBA network without charging a separate inbound placement fee.
The placement fee savings depend on your shipment profile and how much Amazon would have charged for placement under a direct-to-FBA model. For some sellers, this is a material savings. For others, it is negligible.
Auto-replenishment shifts control from you to Amazon. Amazon decides when to replenish, how much to replenish, and which FBA facility receives the inventory.
Most of the time, that automation works well. But it can create problems if:
You can override auto-replenishment with manual controls, but that adds back the work AWD is supposed to eliminate.
AWD works best for Amazon-first brands with predictable demand patterns. It works less well for brands that:
AWD is a bulk storage and replenishment system. It is not a full-service 3PL.
AWD receiving times are generally fast, but replenishment from AWD to FBA can take longer than shipping directly to FBA. Some sellers report replenishment transfers taking several days to a week.
That timing lag can cause problems if your FBA inventory runs lower than expected and AWD replenishment does not arrive fast enough. You need to maintain a buffer in FBA to absorb variability in replenishment timing.
Amazon’s service levels and operational consistency have improved since AWD launched, but the program is still newer than FBA. Expect occasional delays, receiving errors, or inventory discrepancies.
Not all products are eligible for AWD. Amazon has relaxed some restrictions since launch, but limits still exist.
As of early 2026, AWD generally does not accept:
Amazon has recently added eligibility for shoes, expiration-dated products, and non-sort conveyable items. But specific eligibility rules vary by product type and may change without notice.
Confirm your SKUs are eligible before sending inventory to AWD. Ineligible products sent to AWD may be refused, returned, or stuck in limbo.
Choosing between AWD, FBA-only, and a 3PL depends on your inventory profile, sales velocity, channel mix, and control preferences.
AWD works best if you:
Example: A brand selling home goods on Amazon with steady sales velocity, seasonal buying windows, and a preference for low-touch logistics. The brand orders large quantities from overseas suppliers, stores bulk inventory in AWD, and lets auto-replenishment keep FBA stocked year-round.
A 3PL works better if you:
Example: A brand selling supplements on Amazon, Shopify, and wholesale. The brand requires lot tracking, expiration date management, custom bundling for subscription boxes, and fast turnaround on sample orders. A 3PL with dedicated account management fits better than AWD’s automated system.
Some sellers use both AWD and a 3PL. They send high-velocity, FBA-only SKUs to AWD and send multi-channel or complex-prep SKUs to a 3PL.
A hybrid model adds operational complexity. You manage two inventory pools, two shipment workflows, and two cost structures. But it can work if the volume and margin justify the extra overhead.
AWD is a strong fit for sellers who:
AWD also fits sellers who are already using FBA and want to reduce storage costs without changing their fulfillment model. If you are happy with FBA but frustrated by storage fees, inbound placement fees, or restock limits, AWD addresses those pain points directly.
AWD is a weaker fit for sellers who:
If you are a smaller seller (under $500K annual Amazon revenue), AWD’s cost savings may not justify the operational learning curve. Start with FBA-only or a small 3PL relationship until your volume grows.
If you sell in categories with high return rates, short product life cycles, or rapid SKU turnover, AWD’s bulk storage model is less useful. You need more flexibility than AWD’s automated system provides.
Enrollment in AWD is straightforward. Most sellers can access AWD directly from Seller Central without a separate application or approval process.
Steps:
Amazon may still limit AWD access for some seller accounts based on performance history, account health, or product category. If you do not see the AWD option in Seller Central, contact Seller Support to confirm eligibility.
Before sending inventory to AWD:
Amazon recommends starting with a small test shipment (one or two pallets) to confirm the process works smoothly before committing a large volume of inventory.
AWD storage fees are lower than FBA storage fees. But AWD also charges processing and transportation fees that FBA does not charge separately.
Whether AWD is cheaper overall depends on how long you store inventory in AWD, how much cube your product occupies, and whether you qualify for discount tiers. Run a cost model using your actual product and volume data to get an accurate comparison.
No. AWD does not fulfill customer orders. It stores bulk inventory and replenishes FBA. You still need FBA to fulfill Prime orders with fast delivery.
Think of AWD as an upstream storage layer that reduces how much inventory you hold in FBA at any given time.
Yes. AWD can distribute inventory to non-Amazon destinations, including your own warehouse, a 3PL, wholesalers, or other fulfillment networks like Walmart Fulfillment Services.
Multi-channel distribution is less common than FBA replenishment, but it is a supported capability. If you want to use AWD as a central inventory pool for multiple sales channels, you can request distribution to non-Amazon destinations through Seller Central.
AWD generally does not accept:
Amazon has recently expanded eligibility to include shoes, expiration-dated products, and non-sort conveyable items. Eligibility rules vary by product type and may change without notice. Check the current Seller Central guidance before sending inventory to AWD.
AWD is worth using if:
AWD is not worth using if:
If you are managing a large catalog, selling across multiple channels, or unsure whether AWD fits your inventory profile, get help from a logistics consultant or an Amazon agency with supply chain experience.
The right inventory model depends on your unit economics, sales velocity, channel mix, and operational preferences. A generic “AWD is always better” or “3PLs are always better” answer does not exist. You need to model the tradeoffs based on your actual business.
