Peak season puts Amazon sellers in a familiar bind: you need enough FBA stock to stay Prime-eligible, but stuffing every unit into fulfillment centers drives storage costs and bumps into capacity limits. Sending too little risks stockouts right when ads and promotions are working hardest.
Amazon Warehousing and Distribution (AWD) is Amazon's bulk upstream storage program. You send inventory to AWD in volume, keep it at lower storage rates with no holiday surcharge, and let auto-replenishment move units into FBA when Prime-ready centers need them. Amazon's program page also says AWD pricing covers FBA inbound placement, so you don't pay a separate inbound placement fee for that replenishment path.
In this guide, you'll learn what AWD is, how it differs from FBA, who and what is eligible (including the July 2026 sortable size update), how much storage and processing cost, how to create your first inbound shipment in Seller Central, how auto-replenishment settings work, and a practical Q4 stocking plan that pairs with capacity and low-inventory rules.
AWD only helps if you chose a product worth stocking through Q4. This free checklist helps Bubba Academy students pick the right product, plan the first inbound, and avoid costly rookie mistakes.
Amazon Warehousing and Distribution (AWD) is a bulk storage solution that holds inventory upstream, then distributes it to the Amazon store and to non-Amazon sales channels. Amazon's program page describes AWD as the place to keep large quantities at lower cost while auto-replenishment keeps FBA stocked.
Unlike a fulfillment center, an AWD facility is optimized for bulk storage, not picking every customer order. FBA remains the network that packs and ships Prime orders to shoppers.
Amazon's AWD guide summarizes the split this way:
Holiday demand is when storage mistakes get expensive. Amazon's AWD page states pricing is pay-as-you-go with no additional costs for the holiday season. The same page says AWD pricing covers FBA inbound placement, so there is no separate charge for that service when inventory moves from AWD into FBA.
Amazon's Supply Chain by Amazon overview also says that with auto-replenishment enabled, you do not have to worry about FBA capacity limits or low-inventory charges the same way you do when you only stage stock inside fulfillment centers. That pairs directly with our guides on FBA capacity limits and the FBA low-inventory-level fee.
Amazon's program FAQ says auto-replenishment uses a proprietary model that watches inventory in Prime-ready fulfillment centers and triggers moves from AWD so products stay in stock. If you leave auto-replenishment enabled, Amazon says products are considered in stock and buyable when they are received by AWD, and Amazon manages replenishments so you do not have to micromanage every restock into FBA.
Delivery dates for units still in AWD (or in transit from AWD to a fulfillment center) can differ from units already sitting in a fulfillment center. Plan ads and deals around inventory that is already Prime-ready, not only inventory that is "on the way" from AWD.
Amazon recommends a Professional selling account. There is no enrollment fee for FBA sellers; you are charged when you send inventory to AWD facilities.
Amazon's guide says most retail categories are eligible, including apparel, beauty, books, electronics, home goods, toys, and sports. It also notes recent additions such as shoes, expiration-dated products, and non-sort conveyable products. Always confirm eligibility in Seller Central when you book a shipment.
Amazon's AWD guide and inbound PDF describe carton limits of boxes smaller than 25" × 25" × 25" and under 50 lb, with one unique SKU per carton (no mixed SKUs). Expiration-dated products need at least 185 days of remaining shelf life when sent to AWD.
Separately, Amazon staff confirmed a policy update effective July 31, 2026: AWD only accepts sortable items smaller than 18" × 14" × 8" and weighing less than 20 lb. Items over those unit thresholds should go directly to the fulfillment network with the Send to Amazon workflow, according to a Seller Forums reply from KJ_Amazon. Check the live eligibility message in Seller Central before you book Q4 freight, because oversized units that used to be fine may now be rejected at AWD.
Amazon publishes base, Smart storage, and Amazon managed rates on the AWD program page. Figures below are from that page (confirm live rates in Seller Central before you plan):
Amazon's guide says AWD has no seasonal surcharges and no long-term storage fees like the ones that apply inside FBA for aged inventory. To estimate total landed cost after AWD storage and FBA fees, use our walkthrough on true per-unit cost on Amazon FBA.
Amazon's guide says Smart Storage Discount eligibility is visible on the AWD inventory dashboard. For the Amazon managed rate, Amazon lists an auto-replenishment ratio of 70%+ and combined historical days of supply of 70+ days, plus using Supply Chain by Amazon managed transportation (Amazon Global Logistics, Partnered Carrier program, or Amazon Global Selling SEND) for that SKU.
Amazon's guide says to open Seller Central, go to Inventory → Warehousing and distribution (AWD), open the Manage service tab, and select Create shipment. The Send to Amazon Warehousing and Distribution workflow then walks through:
Amazon's AWD inbound shipment PDF adds destination region choices (East Coast, West Coast, South Central, South East, or Amazon Assigned). If you are unsure, Amazon Assigned lets Amazon pick a distribution center based on lead time and capacity. The same PDF notes Amazon Global Logistics does not deliver to South Central (Texas).
AWD is one piece of a full Amazon inventory system. Bubba Academy's step-by-step program shows you how to choose products, plan inbound, manage FBA capacity, and keep listings in stock through peak season.
Within about 2 to 3 days after your first AWD shipment, Amazon says you get access to the AWD inventory page (Inventory → Warehousing and distribution (AWD) → View inventory). From the FBA Replenishment column you can choose:
Amazon notes that for multiple seller SKUs under the same ASIN, it uses the highest value set across those SKUs, and that setting updates can take up to 24 hours to take effect.
Amazon's guide suggests setting the minimum FBA threshold high enough to avoid stockouts and low enough to limit FBA storage. Review thresholds monthly, and raise FBA bands before Black Friday and Cyber Monday while keeping safety stock in AWD.
Use AWD as the bulk layer and FBA as the Prime-ready layer:
AWD is storage and replenishment, not a substitute for listing quality, ads, or account health. You still need converting listings, clean Account Health, and enough Prime-ready FBA units for the orders you expect this week.
The key takeaways:
Your next step: Open Warehousing and distribution (AWD) in Seller Central this week, confirm which ASINs are still eligible after the July 2026 size update, and create your first (or next) inbound before the heaviest holiday weeks.
Bubba Academy trains sellers on product research, Brand Registry, listings, FBA inventory, capacity planning, and ads, so you can stay in stock without overpaying for storage.
Join Bubba Academy Today →AWD is Amazon's bulk storage program that holds inventory upstream, auto-replenishes FBA when Prime-ready centers need stock, and can distribute to non-Amazon sales channels from the same pool.
No. Amazon's AWD program page says pricing is pay-as-you-go with no additional costs for the holiday season, unlike seasonal storage pressure inside FBA.
Amazon says that with auto-replenishment enabled, products are considered in stock and buyable when received by AWD, and that Amazon manages replenishments so you do not have to worry about FBA capacity limits the same way. Confirm current behavior in Seller Central for your account.
Amazon staff stated that starting July 31, 2026, AWD only accepts sortable items smaller than 18" × 14" × 8" and under 20 lb. Larger items should be sent directly to the fulfillment network with Send to Amazon. Still follow carton rules (one SKU per box) shown in Seller Central.
No. Amazon's AWD FAQ says you cannot move inventory from FBA to AWD because fulfillment centers and AWD facilities store inventory differently.
