Updated November 12, 2026.
Walmart has become an important growth channel for ecommerce brands. Walmart’s online business continues to grow. For the quarter that ended July 31, 2026, the company reported 24% year-over-year growth in U.S. ecommerce sales and 52% growth in U.S. Marketplace sales. These results demonstrate Walmart’s growing opportunity for sellers.
For brands considering expanding into the channel, fulfillment is a large part of the strategy. Like any other marketplace fulfillment operation, products need to remain available, delivery promises must be credible, and the cost to serve each order should leave room for profit.
How does Walmart fulfillment work?
Walmart Fulfillment Services (WFS), which launched in 2020, allows sellers to use Walmart’s logistics network for storage and customer-order fulfillment. A third-party logistics (3PL) provider can complement that network by preparing and replenishing inventory or fulfilling Walmart orders directly under a seller-fulfilled model.
When using WFS, sellers enroll eligible products and send inventory to assigned Walmart fulfillment centers. When a customer orders, Walmart picks, packs, and ships the item, and handles order-related customer support and returns.
The seller remains responsible for the product assortment and replenishment decisions. Sending inventory into WFS does not transfer responsibility for demand planning or product compliance.
What services are included in WFS?
Walmart offers a range of service through WFS, plus optional supply-chain services, including inventory transfers and preparation that are evaluated separately from the base fulfillment fee. Typical WFS services include:
- Inventory storage. Products are held in Walmart’s fulfillment network until needed for orders. Storage fees depend on product volume and time in storage.
- Order fulfillment and shipping. Walmart handles picking and packing, with fast delivery options for eligible items. Two-day delivery is an important benefit, although heavier products and certain circumstances can require longer transit times.
- Customer support and returns. Walmart manages order-related questions and returns. That reduces the seller’s workload, but return processing, removal, and disposal may still create charges.
Who is eligible for WFS?
Sellers need a Walmart Marketplace account and eligible products. Walmart’s current program overview lists these principal product requirements:
- Maximum packaged weight of 500 pounds and dimensions of 120 × 105 × 93 inches.
- No regulated or perishable products that require temperature control.
- Products must be permitted under WFS and Marketplace policies, and inventory must ship from within the U.S. or clear customs before reaching the facility.
Some products need additional review, and eligibility should be confirmed for the actual SKU and packaging configuration rather than assumed from the product category.
WFS does not require sellers to enroll a minimum number of products. A smaller selection can provide a useful starting point for evaluating demand and margins.
What does Walmart fulfillment cost in 2026?
WFS charges for fulfillment and storage, with additional charges for certain product characteristics and services. Walmart Marketplace referral fees are separate and vary by category and sales price.
Current WFS fulfillment and storage fees
The table below reflects Walmart’s published WFS pricing and detailed fee guide, checked November 10, 2026. These are standard published rates, excluding temporary promotions. Fees are subject to change.
| Cost category | Weight, condition, or period | Published charge |
| Standard fulfillment | Shipping weight up to 1 lb. | $3.45 per unit |
| Standard fulfillment | 2 lb. | $4.95 per unit |
| Standard fulfillment | 3 lb. | $5.45 per unit |
| Standard fulfillment | 4–20 lb. | $5.75 + $0.40 for each lb. above 4 |
| Standard fulfillment | 21–30 lb. | $15.55 + $0.40 for each lb. above 21 |
| Standard fulfillment | 31–50 lb. | $14.55 + $0.40 for each lb. above 31 |
| Standard fulfillment | 51 lb. and above, within standard-item eligibility | $17.55 + $0.40 for each lb. above 51 |
| Standard-item surcharge | Apparel | Add $0.50 per unit |
| Standard-item surcharge | Eligible hazardous materials | Add $0.50 per unit |
| Standard-item surcharge | Retail price below $10 | Add $1 per unit |
| Oversize 1 | Longest side >48–96 inches; median side >30 inches; or length + girth >105–130 inches | Add $3 per unit |
| Oversize 2 | Longest side >96–108 inches; or length + girth >130–165 inches | Add $20 per unit; base weight pricing starts at the 90-lb. rate |
| Big and bulky fulfillment | Eligible freight-shipped items, up to 500 lb. | $155 + $0.80 for each lb. above 90 |
| Storage, inventory aged up to 365 days | January–September | $0.75 per cubic foot per month |
| Storage, inventory aged up to 365 days | October–December, stored up to 30 days | $0.75 per cubic foot per month |
| Storage, inventory aged up to 365 days | October–December, stored more than 30 days | $0.75 + $1.50 per cubic foot per month, totaling $2.25 |
| Long-term storage | 366–450 days | $2.25 per cubic foot per month |
| Long-term storage | More than 450 days | $7.50 per cubic foot per month |
| Unplanned preparation | Missing or incorrect item label | $0.65 per unit |
| Unplanned preparation | Missing or incorrect poly bag | $0.80 per unit |
| Other costs | Returns, removal/disposal, inbound transportation, optional services, and Marketplace referral fees | Additional; calculate for the applicable SKU and service |
The long-term storage tiers took effect June 30, 2026. Standard-item surcharges do not apply to big and bulky fulfillment.
Standard items must meet all applicable limits: packaged unit weight up to 150 pounds, longest side up to 108 inches, and length plus girth up to 165 inches. Girth equals twice the sum of width and height. Products outside those limits may fall into the big and bulky program, subject to its eligibility rules.
Having accurate packaged measurements is important. Dimensional weight uses length × width × height in inches divided by 139. Walmart’s cost estimator applies the relevant weight, packaging, and rounding rules. Product weight alone may understate the billable shipping weight.
That said, the useful comparison is the complete cost per sale, including inventory preparation and getting stock to Walmart. A low fulfillment charge does not compensate for excess inventory aging in storage.
What are the advantages of WFS?
Access to a growing channel
WFS helps brands serve Walmart shoppers without building their own parcel fulfillment network. Fast delivery and recognizable fulfillment messaging can also support conversion.
Walmart’s August 2026 program overview reports average GMV growth of 50% for items with the “Fulfilled by Walmart” tag and delivery promises of two days or less, based on Walmart first-party data from February 2025 through March 27, 2026. That is a reported average, not a guaranteed result for a new seller or evidence that fulfillment alone caused the increase.
Established execution and support
Walmart handles the customer-order workflow and related support, allowing sellers to use an established network as volumes grow. Published rates also make it possible to model individual products before enrolling them.
Those benefits are strongest when the brand maintains sufficient inventory without sending more stock than demand can support.
What limitations should brands consider?
Preparation and inventory remain the seller’s responsibility
Products must arrive ready for Walmart’s receiving process. Missing labels and incorrect packaging can add charges or delay availability. WFS handles the customer order after inventory becomes available; it does not eliminate the work required to get that inventory into the network.
Returns and aging inventory affect margins
Return processing is not universally free for sellers. Charges depend on the item and circumstances, with Walmart-at-fault exceptions described in its fee guide. Slow-moving stock also faces the long-term storage tiers shown above.
Branding and geographic options require review
Brands should confirm packaging options instead of assuming every shipment supports a customized unboxing experience. Walmart’s routing guidance permits certain inserts and marketing materials, while Multichannel Solutions uses unbranded packaging. Neither should be confused with a fully customized 3PL packout.
How Walmart fulfillment connects with a 3PL
Preparing and replenishing WFS inventory
A 3PL can receive inventory from suppliers, hold reserve stock, and prepare replenishment shipments using Walmart’s current requirements. This can include inspection and labeling work, plus carton and pallet preparation appropriate to the shipment.
The brand and provider need a clear handoff for shipping-plan creation, assigned destinations, and freight bookings. Walmart’s routing guide requires shipments to go to assigned fulfillment centers and specifies requirements for packaging, receiving labels, and delivery arrangements.
A replenishment plan should also distinguish “delivered” from “available to sell.” Goods still being received cannot be treated as available WFS stock. Reserve inventory at a 3PL may reduce overstocking inside Walmart’s network, but it adds its own storage and handling costs. The value depends on demand and replenishment lead times.
Fulfilling Walmart orders directly
WFS is one option. Under seller fulfillment, a brand can use a 3PL to ship Walmart Marketplace orders directly to customers. That arrangement requires accurate inventory updates and shipment confirmation, with service commitments that meet Walmart’s applicable seller requirements.
A hybrid model may put selected SKUs into WFS while other products remain seller-fulfilled. Systems need explicit routing rules, so the same order is not dispatched twice, and the same inventory is not promised from two locations.
Supporting the rest of the brand’s business
A 3PL may also handle DTC orders, promotional kits, and wholesale shipments. Wholesale purchase orders for Walmart’s retail network are a separate workflow from replenishing a seller’s WFS inventory, with different commercial and receiving requirements.
Kase’s fulfillment technology supports Walmart marketplace integrations, while its omnichannel fulfillment services connect consumer orders with retail and B2B execution. Its value-added services provide packaging and labeling capabilities that brands can evaluate against their specific preparation needs. The WFS replenishment scope should be agreed for the actual product assortment.
How to get started with WFS
Brands first need an approved Walmart Marketplace account. Existing sellers can add their WFS details into the Seller Center, then enroll eligible items with the required product information.
Before the first shipment, the brand should validate packaged measurements and model the full cost of selling each SKU. The shipping plan identifies where inventory must go. Preparation and carrier arrangements then need to match that plan, followed by reconciliation of what Walmart receives and makes available for sale.
Walmart fulfillment creates valuable exposure to a growing customer base. A sustainable channel plan accounts for the inventory journey before the customer clicks “buy,” including who prepares stock and how it is replenished. WFS and a 3PL work well together when each has a defined role, and the combined costs support the brand’s margins and delivery promises.
Walmart fulfillment FAQs
Is Walmart Fulfillment Services required to sell on Walmart Marketplace?
No. Sellers can use WFS or manage fulfillment themselves, including through a 3PL. Seller-fulfilled orders must meet Walmart’s applicable shipping, tracking, and customer-service requirements.
What costs should sellers consider besides WFS fulfillment fees?
The full cost includes storage, Marketplace referral fees, and transportation into Walmart’s network. Product preparation and returns may add charges, while slow-moving inventory can incur higher storage fees.
Can a 3PL prepare and send inventory to Walmart fulfillment centers?
Yes. A 3PL can inspect products, apply required labels, prepare shipments, and coordinate transportation to assigned Walmart facilities. The seller and provider should agree on who creates shipping plans and reconciles received inventory.
Can Walmart fulfill orders from a brand’s own website?
Yes. Walmart Multichannel Solutions uses WFS inventory to fulfill orders from supported sales channels, including a brand’s website. Its pricing and service terms differ from standard WFS fulfillment for Walmart Marketplace orders.
Can a brand use WFS and a 3PL together?
Yes. A brand might use WFS for selected Walmart products while a 3PL holds replenishment stock and fulfills other orders. Clear inventory allocations and order-routing rules help prevent overselling and duplicate shipments.
