Managing your items and inventory in Supplier One is essential for accurate product listings, smooth replenishment, and compliance with Walmart’s supplier requirements. In 2024, Supplier One replaced Item 360 as the central hub for catalog management, item setup, item maintenance, and brand registration. All these features can now be managed in Supplier One.

1. Catalog Management

The Catalog Dashboard is the primary platform for Walmart suppliers to manage, review, and optimize their product information. This dashboard not only provides you with the visibility of your entire product lineup but also plays a significant role in maintaining accuracy, compliance, and optimization for selling on Walmart.com.

Catalog Management Dashboard 

The dashboard is used by suppliers to check their product details for accuracy, manage content quality, and ensure their items pass Walmart’s standards

The Catalog Dashboard is divided into two main sections:

  • Products (by GTIN/UPC) – This section focuses on individual products, identified by their unique barcode numbers (GTIN or UPC). It’s where suppliers manage specific product details, like descriptions, pricing, and images.
  • Item Configuration and Hierarchies (by WIN) – This section addresses how products are grouped and structured within Walmart’s system. Instead of focusing on individual items, it organizes them using Walmart Item Numbers (WINs). This includes managing product variations (like different sizes or colors), bundled products (assortments), and special packaging (like shippers).

Key Areas in the Products Dashboard

1. Content Quality Scores

Every product has a Content Quality Score, which determines the extent to which your product information is complete and optimized on Walmart.com. Why is this score important? Higher scores increase visibility for your product in search results, enhancing your opportunity for customer interaction and sales.

Screenshot 2025-05-28 at 9.22.50 AM.png
  • Your Content Quality Score comes from two major components: 

a. Core Content (60%) – Contains the most identifiable product aspects that guarantee your customers know what it is that you are selling. This includes, but is not limited to: 

  • Product title
  • Main functionalities
  • Store description
  • Pictures

Product Type Attributes (40%) – These are features of the product that enable Walmart to classify and describe your product. The less precise these attributes are, the more difficult it will be for customers to locate your product in search results.

Basic Item Info

When you click on the relevant products content quality score, it will take you to a dashboard that allows you to make edits to both the core content of the product and the product type attributes.

Note: Walmart will highlight some sections in a bright yellow color. These highlighted attributes are Walmart’s suggestions to the supplier on information that is missing. Walmart says, “Incorporating the feedback from these insights will improve the overall content quality score for this item.”

2. Filters


Filters are your best friend for efficiently managing large catalogs. These tools help you quickly identify, analyze, and organize your products based on specific attributes or statuses.

Screenshot 2025-05-28 at 9.47.44 AM.png

You can filter by useful categories like:

  • Custom Attributes
    • Add custom filters
  • Hierarchy & Classification
    • Department / Fineline, etc.
    • Product Type
    • Product Category
  • Product Content
    • Product Name

4. Creating Custom Datasets 

Screenshot 2025-05-28 at 10.00.55 AM.png

In your catalog, you can create custom datasets so that you can simplify your reporting and tracking needs. You can either add your own custom attributes or pick up to 12 of these attributes:

  • Available Channels
  • Brand
  • Brand Code
  • Color
  • Content Quality
  • DSV - Available to Sell Inventory
  • DSV - On-Hands Inventory
  • DSV - Total Reserved Inventory
  • Is Preorder
  • Is Variant
  • Item ID
  • Offer Price
  • Online Orderable
  • Online Replenishable
  • Primary WIN
  • Product Category
  • Product Type
  • R2D2 Subcat
  • Ratings/Reviews
  • Release Date
  • Shipping Dimensions
  • Site Dates
  • SKU
  • Supplier / Seller
  • Walmart.com Inventory
  • Walmart.com Price

Item Configuration and Hierarchies (by WIN)

Item Configuration and Hierarchies is the process Walmart uses to define how products are sorted, packaged and shipped using Walmart Item Numbers (WINs) instead of typical barcodes like GTIN and UPC.

Proper setup of items is important when dealing with multiple groupings of products, like:

  • Assortments: Related products, like a full line of skincare products
  • Multi-packs: Bundled items packaged as one, such as a 3-pack of socks
  • Shippers: Special packages for shipping large quantities or for in-store display
  • Product families: Variations of the same product, such as a T-shirt which comes in different sizes and colors

If these configurations are absent or out of date, it can lead to issues like products not being shipped or restocked correctly, they can be inaccurately represented in stores or online, and suppliers can be charged compliance fees for setup errors.

Screenshot 2025-05-28 at 10.02.52 AM.png

The catalog dashboard provides filters to sort items by assortment type, shipper configurations, or individual item configurations. Similar to the Products section, these filters enable suppliers to manage items by department, fulfillment method, supply chain status, unit cost, replenishment options, and online publish status.

Creating Custom Datasets for Item Configurations

Just like with product-level datasets, suppliers can also build custom datasets specific to item configurations. Options include:

  • Accounting Dept, Fineline
  • Buying Region
  • Corporate Replenishable
  • DSV - Available to Sell Inventory
  • DSV - On-Hands Inventory
  • DSV - Total Reserved Inventory
  • Fulfillment Method
  • GTIN
  • Item Effective Date
  • Item ID
  • Item Type / Subtype
  • Last Changed
  • MBM Code
  • Merchant
  • National Drug Code
  • Online Replenishable
  • Orderable Pack GTIN
  • Orderable Pack Qty
  • Product Category
  • R2D2 Subcat
  • Supplier Stock Number
  • Supplier
  • Unit Cost / Selling Price
  • Vendor Contract #
  • Warehouse Alignment Code


2. Setup Hub 

The Setup Hub in Supplier One is the central workspace for introducing new products and configurations into Walmart’s ecosystem.

There are 4 main sections incorporated in the Setup Hub: Item Proposals, Items, Shipper, and Multibox.

Screenshot 2025-05-28 at 11.29.17 AM.png


Item Proposals

Item proposals are your entry point into offering new items to Walmart. This feature allows you to add comprehensive information about possible items, giving Walmart’s merchandising team everything they need to review adding your items to their inventory.

Located in the top right-hand corner of the Setup Hub homepage is the “My Proposed Items” section. These proposals will display all the items that were added during the supplier onboarding process.

Screenshot 2025-05-28 at 11.30.07 AM.png

Adding an Item Proposal

On the setup hub main dashboard, navigate to Item Proposals box and click on, “add an item proposal.” 

Screenshot 2025-05-28 at 11.31.08 AM.png

Select a Product ID Type and provide the Product IDs.

Screenshot 2025-05-28 at 2.57.01 PM.png

Then, in the bottom right corner of the page click the blue “Download spreadsheet” button.

The downloaded spreadsheet will be broken up into 5 main categories: 

  • Product Identifiers: This will include your Product ID, Product ID type, etc. 
Screenshot 2025-05-28 at 2.57.58 PM.png
  • The minimum amount of information required for a merchant to consider your product. 
Screenshot 2025-05-28 at 2.58.53 PM.png
  • Recommended information for improved merchant discoverability and decision making. 
Screenshot 2025-05-28 at 2.59.56 PM.png
  • Recommended information for improved assortment and supply chain analytics.
Screenshot 2025-05-28 at 3.00.05 PM.png
  • Optional information.
Screenshot 2025-05-28 at 3.01.36 PM.png

Fill out all the relevant information for your item proposal and upload it back in Supplier One.


Items 

The Item Setup section is where you configure new products, ensuring all necessary attributes and compliance information are accurately entered. 

Adding an item: 

On the main dashboard of the setup center, proceed to the items box and click on, “Add an item.”

Screenshot 2025-05-28 at 3.03.28 PM.png

To initiate the setup of a new item, you’ll first clarify how the product will be sold—either online, in Walmart stores, or both. If your product will be sold online only (Drop Ship Vendor), click “No” when asked, “Will this item be sold in stores?” If the item will be sold in physical Walmart stores (Direct Store Delivery), click “Yes.”

Screenshot 2025-05-28 at 3.04.36 PM.png


If you’re selling through Walmart stores, you’ll specify next whether your products will ship to Walmart Fulfillment Centers (FC), Distribution Centers (DC), or store-direct under the “Owned” or “Direct Store Delivery” fulfillment types. As mentioned before, Owned is when the supplier ships to Walmart’s DC, and DSV is when the supplier bypasses the Walmart facilities and ships straight to a customer or stores.

If your product is not shipping to physical stores, you’ll select “Ship to Walmart FC or DC” to indicate the product is Owned inventory controlled by Walmart for online fulfillment or distribution.

Screenshot 2025-05-28 at 3.05.23 PM.png

If you are adding the item directly to Supplier One and not through the Global Data Synchronization Network (GDSN), do not check the check box titled “GDSN-synced item info.” Walmart’s process will take all item information you provide. This means both new and updated information will be integrated into Walmart’s catalog.

After you have selected your mode of fulfillment (DSD, DSV, or Owned), you will move on to entering some specific product attributes. These include mandatory fields such as product name, brand name, unit cost, etc.

For a detailed setup guide on DSV items, download our Supplier One: Step-by-Step Item Setup Guide.

Before you submit, take a moment to review all your information for accuracy. If anything’s missing or needs correcting, a red banner will appear at the top of the page to guide you through the errors.

Screenshot 2025-05-29 at 2.02.03 PM.png

Once all details are finalized and accurate, click “Submit” to finish your item setup request. You will be prompted to input a description of the item setup request before clicking “Submit” again to complete.

Screenshot 2025-05-29 at 2.02.51 PM.png


Once completed, you will then be able to track its status through the Submissions Manager.

Shipper Setup 

A Shipper is a special type of packaging that gathers a number of products together to simplify shipping and in-store display. It’s a pre-loaded display that can go right onto the sales floor, often used for promotions or bulk sales.

Shippers often come in different sizes:

  • Full Pallets – Large displays for warehouse clubs or high-traffic areas.
  • Half Pallets – Medium displays for standard retail aisles.
  • Quarter Pallets – Compact displays for end caps or check-out lanes.

A shipper contains a number of separate products (referred to as Content Items or Child Items), each with its own barcode (GTIN). Meanwhile, the shipper itself receives one Prime GTIN (also referred to as Parent GTIN) so that Walmart can track and manage it as a single unit. For example, a shipper might match tortilla chips and queso together in one convenient display.

Adding a Shipper 

To begin adding a new shipper, navigate to the Setup Hub main dashboard and click the “Add a shipper” button.

Screenshot 2025-05-29 at 2.04.23 PM.png

Walmart will automatically check if your shipper’s data is already on the Global Data Synchronization Network and import it if found. If no existing data is found, you can manually enter the details in Supplier One.

You’ll need to select the following key identifiers to accurately define your shipper:

  • 6-digit Supplier ID (your company’s unique Walmart identifier).
  • 3-digit Vendor Contract Number (your agreement with Walmart).
  • Prime GTINs (the shipper’s individual product codes). You may enter up to 500 Prime GTINs by copying and pasting from a spreadsheet.
Screenshot 2025-05-29 at 2.05.10 PM.png

Before you submit your shipper data, make sure the Prime GTINs you enter are not already assigned to products in Walmart’s inventory. If your product hierarchy is synced via the Global Data Synchronization Network, ensure each GTIN has a GLN and the GLN maps to the Supplier ID and Vendor Contract Number you selected.

After entering your initial information, click “Next” to proceed to the Attributes Page, where you will fill out Prime Attributes (shipper-related product detail) and Content Attributes (product description detail). To ensure that you have captured all of the fields, click the “Expand All” button to view and fill out each one. 

If Walmart discovers your shipper in GDSN, it will prefill some fields, such as any Content Item GTINs that correspond to your Prime GTINs. 

Once all details have been finalized and verified, click “Submit” to complete your item setup request. You will be asked to provide a description of the item setup request before clicking “Submit” again to finish.

Screenshot 2025-05-29 at 2.06.01 PM.png


Once completed, you will then be able to track its status through the Submissions Manager.


Multibox Setup 

A Multibox Item (or an inflex kit) is a product that is shipped in multiple boxes instead of one. Each box is given a separate GTIN, but the whole range of products is tracked under one Sellable GTIN. This setup is commonly used for large or complex items that cannot ship in a single package.

For example, a home gym set could include a treadmill in one package, dumbbells in another package, and an instruction booklet in a third package. There is a separate GTIN for each package, but the entire gym set is sold under a single Sellable GTIN.

Adding a Multibox: 

On the setup hub main dashboard, navigate to the multibox section and click on, “Add a multibox.” 

Screenshot 2025-05-29 at 2.07.12 PM.png

When setting up a multibox item, Supplier One will automatically default the selection to “No” for in-store sales because multibox items are currently supported only for eCommerce.

Next, indicate how your multibox products will be delivered by selecting the appropriate shipping option:

  • For directly handled Walmart products, choose “Ship to Walmart FC, DC, or Store” (Owned inventory).
  • If the items will be shipped to the customer directly, select “Ship to Customer” for DSV.
Screenshot 2025-05-29 at 2.08.04 PM.png


Click Next after you’ve selected the Supplier ID and contract number.

When setting up a multibox item, you’ll start by entering a Sellable GTIN which will be the identifier for the whole set, and the Component GTINs for each item in the set. You’ll also specify the quantity of each component to define exactly what’s included.

A single Sellable GTIN can be used for multiple configurations. For example, one configuration of the multibox can have one master item and two accessories, whereas another configuration can have the same master item but with four accessories. Both are treated as different sets in Supplier One.

Remember Sellable GTIN and Component GTINs must be unique - i.e. not previously used in Walmart’s Catalog for an active item setup or assigned to a Walmart Item Number. If any of these GTINs are already linked to existing items, the system will block the setup to prevent duplicate listings. Always verify your GTINs before submitting to avoid errors.

3. Maintenance Hub

Screenshot 2025-05-29 at 2.09.25 PM.png

Product Content & Site Experience 

Once you get to the main dashboard, (Retail Link > Apps > Supplier One > Items and Inventory > Maintenance Hub), you can manage and update product information on Walmart.com by clicking on “product content and site experience.”

Screenshot 2025-05-29 at 2.09.59 PM.png

This functionality enables suppliers to manage basic product information, site data, compliance attributes, and product-level attributes at the GTIN level.

If you need to make small updates you can edit one product at a time directly within Supplier One by selecting an individual item. This is great for quick changes like updating a product description or pricing for a single item. For larger updates across multiple products you can use bulk edits with spreadsheets. This involves exporting product data, making changes in an Excel spreadsheet, and then uploading the updated file back to Supplier One. This is the most efficient way to manage multiple items at once and save time when updating product details in bulk.

Important Tips for Managing and Updating Content

  • When exporting product data always use the same type of Product ID throughout your spreadsheet, such as GTIN, UPC or WIN. 
  • Supplier One will allow you to update information for up to 5,000 products at a time.
  • Make sure to save your spreadsheet in the correct format—Excel Workbook (.xlsx)—before uploading it. Uploading the wrong file type will cause errors and delays in processing updates.
  • Supplier One will also verify uploaded files for missing or incorrect information. If there are issues, the system will generate an error file with what’s incorrect. Fix these errors ASAP so your product listings are accurate and up to date.

Item Configuration & Supply Chain

Screenshot 2025-05-29 at 2.10.47 PM.png

Viewing Item Details in the Catalog

The Item Configuration Overview organizes product attributes into clearly defined sections, making it easy to find the information you need. You can expand or collapse different sections to focus on specific areas such as supply chain details, replenishment methods, and warehouse alignment. 

Supplier One does not, however, currently support updates for certain item types, including Assortments, Import Shippers (General Merchandise), Pharmacy items, and Fees. If you manage these products, you will need to continue using Walmart’s existing processes until updates for these categories become available in Supplier One.

Making Edits to Attributes

If you need to edit any item attributes, simply expand the relevant section and click “Edit” at the top right. The fields that can be edited will be active, while read-only fields will be grayed out. If you inadvertently modify something you don’t want to save, clicking Cancel will return the field to its original value. If a field is locked (read-only), however, you cannot edit it in-place. Instead, you’ll need to follow Walmart’s process, which may involve reaching out to your merchant or Walmart support for assistance.

Bulk Updating Attributes

For suppliers managing multiple products, bulk updates can be helpful. To do this, go to the Maintenance Hub and download an editable spreadsheet with your item information. Once finished, save and upload the spreadsheet to Supplier One to process.

Important Tips for Managing and Updating

Item Configurations:

Regularly review your configurations to avoid any fulfillment errors.

Consistently use the same Product ID type (GTIN, UPC, WIN) in your searches or uploads to prevent confusion or upload errors.

Pay close attention to Walmart’s highlighted recommendations for improving content, as implementing these insights can significantly boost your product visibility and compliance scores.

Cost 

The cost section in Supplier One simplifies the process of submitting and managing cost updates for products across Walmart’s various sales channels. 

Screenshot 2025-05-29 at 2.12.05 PM.png

Exporting Item Data

Before prices can be updated, suppliers need to export product details from Supplier One. The platform allows users to export up to 5,000 Walmart Item Numbers (WINs) at once, making it easier to update multiple products at the same time. Bulk exports are useful for suppliers with large product lists or those needing to apply cost updates across multiple locations.

Supplier One has different cost update templates depending on how a product is sold and shipped.

Cost Templates

Corporate (National-Level) Cost Template – For suppliers that have one price across all Walmart stores and

sales channels.

Direct Ship Vendor (DSV) Node Cost Template – For DSV items that are shipped directly to customers through third-party distributors. This way suppliers can set costs at the distributor level instead of one national price.

Distribution Center (DC) Cost Template – For suppliers that need to set different costs at Walmart’s DC locations, which helps adjust pricing for regional supply and demand differences.

Once you have the correct template downloaded, fill out all fields so the update will process without errors. The most important fields are:

New Cost Value – The new price per unit

Effective Date – When the new cost takes effect

Applicable Locations – Whether it’s nationwide or

specific DCs

Save the file as an Excel Workbook (.xlsx) before uploading to Supplier One.

After you upload the file Supplier One will check for errors like missing fields or incorrect formatting. If there are any issues the system will give you an error report of what needs to be fixed. Fix these quickly so cost updates will process without delay.

Levels of Cost Updates Explained

You can submit cost updates for all types of items, including eCommerce-only (DSV), store-specific, and multi-channel products. However, the specific way your costs are updated will depend on how and where your products are sold.

For eCommerce only products, price changes are applied at the national level, so the same price is used across all fulfillment centers and all online channels. This ensures pricing consistency for customers shopping on Walmart’s website or marketplace.

For Direct Ship Vendor (DSV) products, price changes can be applied at the national level, where one price is used across all distributors, or at the node level, so suppliers can set specific pricing based on individual distribution points. This allows suppliers to account for different shipping costs and regionally based pricing strategies.

Products that are owned and stocked by Walmart, including those sold in stores, can have price changes applied at the national level or the DC level. A national level update sets one price across all Walmart stores, while a DC level update allows for more targeted pricing by warehouse and region. This structure helps suppliers align with Walmart’s supply chain and inventory management.

For products that are Direct Store Delivery (DSD) or multi-channel sales (online and in-store), price changes follow the same approach. Suppliers can choose to apply a national price, so one price is used across all stores and online platforms, or update at the DC level to account for supply chain variations.

High Velocity Distribution Centers (HVDCs) require DC specific price updates regardless of sales channel. When exporting cost templates, these DC fields will be marked. If a supplier wants to apply a corporate-wide price to an HVDC item, they must enter “National” in the DC number field. If only the corporate price and not the DC price is updated, the DC price will remain the same. This can cause purchase order discrepancies if Walmart’s system doesn’t reflect the intended price changes.

DSV Inventory

Suppliers managing Direct Ship Vendor (DSV) items can efficiently update inventory data using a bulk spreadsheet.

Screenshot 2025-05-29 at 2.13.44 PM.png

What You Can Update in a DSV Inventory Export

When you export inventory data, Supplier One lets you choose which facilities and attributes you want to update. The two main inventory attributes you can update are:

Quantity (On-Hand Inventory): This is the number of units you have available to fulfill online orders, including units currently in the shipping process.

Facility Selection: You can export inventory data from all facilities, or choose specific (custom) facilities to update. Keep in mind, Supplier One limits each spreadsheet to 10,000 rows of data. If your export exceeds this limit, consider exporting fewer facilities at a time.

In the export, you’ll see attributes that describe your available inventory, like:

Availability Quantity (On Hand Inventory): How many units you have in stock or in transit, ready to sell online.

Inventory Attributes:

Availability: Make sure your product is marked as available or unavailable.

Quantity (On Hand Inventory): Total units you have available, including units shipping to customers.

Special Consideration (Email Delivery): If your product is digital (like an online gift card or downloadable content), mark this clearly using the Availability Attributes (these items are delivered electronically and don’t require physical inventory updates).

Specifically:

Use the Quantity (On Hand Inventory) attribute only for items that have physical inventory (units you physically

hold and ship).

If your item is digital (e.g. email delivered products), set the Availability Attribute to clearly indicate electronic fulfillment.

Once you’ve exported your spreadsheet, fill in your updated inventory counts and attributes. Remember the spreadsheet will be named with the date and time it was generated—save it as an Excel Workbook (.xlsx) file before uploading.

When you upload your updated inventory file back into Supplier One, the system will check for common data entry errors. If any errors are found, Supplier One will provide an error report for you to down-

load and fix. Fix any highlighted errors and resubmit your file.

After submission, your DSV inventory counts will update almost instantly in the Submission Manager. However, the Full Item Report, which compiles inventory data across all facilities, will update daily. If the inventory counts don’t match immediately after a successful upload, the daily sync might be the cause. Check your inventory overview the next day to make sure everything is correct.

Imagery 

The Imagery section enables you to efficiently upload, manage, and optimize product images on Walmart.com. Strong, high-quality imagery is crucial—it directly impacts customer engagement, increases trust in your products, and drives higher conver-

sion rates.

Supplier One makes image uploads simple by allowing you to manage imagery individually or in bulk. 

Bulk uploads require no complicated processes; instead, images are neatly organized into folders on your desktop, then easily transferred to Supplier One. If you currently upload Fashion imagery via Workhorse, you will need to continue to do so as Supplier One does not support fashion image management yet.

Screenshot 2025-05-29 at 2.15.29 PM.png

Preparing Bulk Imagery for Upload

Before you start uploading, get your images organized by creating folders on your computer. Each product should have its own folder, named with the item’s GTIN. This will ensure images match up with the correct items in Supplier One.

Important:

Name each product folder with its GTIN so Supplier One knows which image goes with which item.

If you’re uploading images for multiple products at once, put all GTIN-named folders in a single parent folder (you can name this folder anything except an actual GTIN).

Supplier One can also create image folders for you when you edit items directly from your catalog, simplifying your workflow.

Uploading Your Images

Once you have your folders ready, you can upload your images using one of two ways:

Drag-and-Drop: Drag your prepared folders from your desktop into the Supplier One upload area.

Choose Folder: Or click Choose folder within Supplier One to browse your computer and select the parent folder of your GTIN folders.

Supplier One will scan your upload and check for common errors like incorrect file names, mismatched GTINs, duplicate images, or unsupported file types. 

If errors are identified, Supplier One clearly outlines them, enabling you to fix these issues quickly. You can then re-upload your corrected images smoothly.

Managing Existing Images

When uploading images for products that already have images, Supplier One will ask you to Add new images to existing images or Replace existing images. This gives you flexibility to do minor image updates or full image refreshes.

On the review page Supplier One provides additional guidance:

Imagery Tagging (Add vs. Replace): Indicates whether new images will supplement or replace existing images.

Image Tagging & Visibility: Set the primary image so your best images show up first to customers.

Once you’re happy with your uploads, enter a brief description and click, “Submit.” Your images will then be reviewed and integrated into Walmart.com.

Helpful Tips for Successful Image Management

Image Quality Counts: Make sure your images meet Walmart’s resolution and formatting requirements to increase product visibility and customer engagement.

Check Image Dimensions and Resolution: High resolution images perform better, reduce returns, and increase customer trust.

Stay Organized: Named folders and files save you time, especially when updating many images at once.

Rich Media 

Supplier One’s Rich Media feature in the Maintenance Hub allows suppliers to easily manage and enhance product listings on Walmart.com by uploading engaging visual content, such as product videos or interactive 360-spin images.

Screenshot 2025-05-29 at 2.16.55 PM.png

Uploading Videos

Retail Link > Apps > Supplier one > Items and inventory > Maintenance Hub > Edit Rich Media > Videos 

Screenshot 2025-05-29 at 2.17.34 PM.png

You can directly upload videos to Supplier One without needing to provide a URL or use a template if you’re updating one product at a time. If you prefer to submit videos for multiple products simultaneously, you can use the Rich Media spreadsheet available from the Maintenance Hub.

When updating through spreadsheets, keep these considerations in mind:

Video and Image URLs: Provide clear URLs for videos and 360-degree spin images. URLs may be hosted internally by Walmart or externally on third-party platforms.

360-degree Images: Walmart.com supports one 360-degree spin image per item. You’ll need to submit exactly 24 URLs. If you have fewer images available (e.g., 12 images), you can repeat them to fulfill the 24-image requirement.

Video Requirements

File Formats: Supplier One accepts .mp4 and .mov files.

File Size: Videos cannot be more than 100MB.

Closed Captions: If your video has spoken audio, closed captions (in .vtt or .srt format) must be included with the upload to meet Walmart’s accessibility standards.

File Naming: Avoid using special characters or punctuation marks in your video file names.

When uploading videos, remember that Supplier One only allows one video per product. If you upload another video for the same item later, the new file will overwrite the existing one. Walmart.com supports up to 8 videos per item, but to add more than one, you’ll need to use a Connected Content Partner.

Supplier One will automatically verify your upload for common errors such as unsupported file formats or overly large files. If any errors appear, you’ll immediately see feedback and be prompted to correct and re-upload your file.

Updates and URL Changes: If you’re replacing an existing video or image, always provide a new URL. If you use the same URL as before, Walmart’s system won’t recognize this as a new upload and your content won’t update.

High quality videos and rich media increases customer engagement and product visibility on Walmart.com. Videos can reduce returns by setting clear expectations and often drive higher conversion rates. Regularly updating and managing rich media content makes sure your products are competitive, accurate, and attractive to online shoppers.

Best Practices and Tips

Keep Video Titles Short and Sweet: Titles should match your video content and under 200 characters.

Consistency: Update your product media to reflect new product information or to enhance customer experience.

Connected Content Partners: If you want to add multiple videos or interactive media, consider using Walmart approved Connected Content Partners for more options beyond Supplier One’s limits.

Submissions Manager

Supplier One’s Submissions Manager is a single place to track all submissions by suppliers, making it easy to monitor and manage updates, item setups, and maintenance requests.

After you submit updates, you will get an email from Walmart Supplier One if further action is needed with a link to the submission.

Understanding the Submissions Manager

Submissions in Supplier One are organized into three sections:

Maintenance: Item maintenance and cost maintenance submissions

Setup: Item setup, shipper setup, and multibox items

Ship Node: DSV inventory updates and lag-time submissions

Use the “Show My Activity Only” to see only the submissions you made instead of the submissions made by other users under the same Supplier ID.

Quickly Finding Your Submissions

To find a specific submission, copy and paste up to 200 Submission IDs into the search bar. Each Submission ID is a unique combination of letters and numbers generated when the submission was created.

You can also filter by:

Quick Filters: Filter by status, such as “Supplier Action Required,” “Walmart Action Required,” or “Completed.” 

All Filters: Filter by Activity Description, Submission Type, Submitted By, Supplier ID, Approver, or Submission Dates. 

Brand Registration

If you sell to Walmart, you may want to make sure your brand is officially recognized in its system. Brand Registration in Supplier One allows you to prove you own your brand and gives you more control over how your products show on Walmart.com. Once registered, you can manage your product listings, brand content, and even create a brand store for your brand.
