As part of Walmart’s ongoing effort to modernize supplier systems beyond Retail Link, the company launched Supplier One in early 2024—a unified platform designed to centralize supplier tasks like item management, order processing, tracking deductions, and optimizing performance all in one place.
Suppliers can access Supplier One as an app through Retail Link or at https://supplierone.wal-mart.com. Walmart uses single sign-on (SSO) authentication, so suppliers with Retail Link credentials also grant access to Supplier One.
Inside Supplier One
The Supplier One dashboard offers a summary of orders and returns shown at the top of the dashboard. Important tasks are located beneath this summary, and important tabs are located to the left.
Order Management
The first of the left-hand menu items is the Orders tab, which provides a place for suppliers to track, review, and manage purchase orders (POs). Suppliers can even create a PO request.

Items/Inventory
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 within the Items and inventory tab.

Quality
Inspection Management allows suppliers to review up to 100 objects either by item #, PO #, Request ID, Process ID, or Inspection ID.
The dashboard offers a clean overview of how many total objects inspected and then categorized by:
Purchase Order
In-progress Inspections
Completed Inspections
Ship Point Management
Suppliers used to operate within the app ASPEN, which was Walmart’s old system to manage ship points and logistics. Through ASPEN, suppliers could update shipping locations, track agreements, and manage changes in their supply chain. The transition to Ship Point Management in Supplier One combines all these functions into one more user-friendly and operationally efficient interface.

Payments
Claims or deductions happen during invoice processing when Walmart finds discrepancies between the purchase order, received goods, and the submitted invoice. These claims are called Accounts Payable Claims. Common reasons for deductions are price differences, quantity mismatches, or allowance discrepancies. Knowing the root cause of these deductions helps suppliers manage their finances better.

Reports
The Reports page in Supplier One is your one-stop destination for accessing critical data across multiple business areas. Whether you need to analyze payments, track inventory, or review order performance, this hub brings everything together in a clean, filterable interface.

Performance
This tab is a treasure trove of information with:
Scorecard: Shows performance with the Supplier Quality Excellence Program (SQEP), and delivery inefficiencies with On-time In-Full (OTIF) metrics.
Return trends: Acts as the claims and returns scorecard and allows suppliers to view returns from GMV or units perspective, as well as a pie chart that represents the reason for return.
OTIF trends: Allows suppliers to review performance metrics for up to 13 weeks in the past.
OTIF charges: Suppliers are able to view OTIF metrics at the PO level as well as within Walmart stores and eCommerce (shown below).
Demand and Forecast
This tab provides two options: Store Demand and Daily Demand.
Store demand gives users week-by-week projections of business performance in different time frames, up to 24 months. This long-term forecast helps to better understand demand trends, align production and inventory plans with Walmart’s expectations, and improve supply chain coordination.
Daily Demand and Inventory Record (DDIR) allow suppliers to monitor the movement of perishable goods throughout the supply chain. Users Select DCs and supplier IDs, then select items, and track items through the supply chain to see how demand is being met.
Apps and Integrations
Walmart first-party (1P) suppliers, such as drop ship vendors (DSV), warehouse, and import suppliers, can all manage their items, orders, and inventory with Walmart's Supplier APIs. The tools and APIs are designed to help suppliers provide and access item information in real time.
Growth Opportunities
This tab supports suppliers as they continue to work with Walmart on a long-term basis with:
Growth Programs: This feature within Supplier One provides actionable insights and tasks to help suppliers increase sales and conversions on Walmart.com.
Review Accelerator: This program helps suppliers to get more customer reviews by incentivizing buyers with a digital reward for leaving feedback.
Events Proposals: This feature allows suppliers to promote their products in stores or online. It is a document that outlines the details of the proposed event, including its purpose, objectives, logistics, and budget, to gain approval from the retailer.
Overlap within Supplier One and Retail Link
While Retail Link remains the homebase for operational data when working with Walmart, Supplier One extends that visibility into the financial space. Together, these tools create a full circle view of a supplier's relationship with Walmart—from purchase order to payment.
A Unified (but Divided) Ecosystem
Each app in Retail Link serves a distinct purpose, but data often overlaps across platforms. Think of Supplier One as the front porch, APIS as the filing cabinet, and APDP as the negotiation desk—each playing a part in keeping supplier finances clean and visible. When used together, these apps form a single connected workflow rather than three separate siloed systems within Retail Link.
Several key data points appear in both Retail Link apps (like APDP and APIS) as well as in Supplier One.
Data Type | Supplier One | Retail Link | Best Use |
Payment Summary | Yes | Yes, via APIS | Supplier One offers an overview; APIS provides detailed remittance |
Deduction Information | Yes, high-level
| Yes, via APDP | Supplier One shows total deduction amounts; APDP manages the dispute process |
Invoice Details | Yes, full view and upload
| Yes, via APIS | Supplier One is the preferred tool for reviewing or submitting invoices |
Vendor and Banking Details | Yes, Profile section
| No | Supplier One is the single source of truth for financial credentials |
Messages | Yes, communications tab | No | Supplier One consolidates finance-related communication in one place. |
Retail Link is essential for performance and compliance, but Supplier One is where finance teams should focus their attention for day-to-day payment accuracy.
Supplier One doesn’t replace APIS and APDP, though. The three apps often work in sequence together. For example:
Supplier One reveals a short-paid invoice or deduction in a remittance summary
APIS provides the granular payment details—reference IDs, check numbers, and transaction history.
APDP allows the supplier to formally dispute a deduction, upload documentation, and track resolution.
The Reason Why the Overlap Matters
For suppliers managing hundreds of invoices or deductions each month, these systems reduce confusion and manual reconciliation. When used together they:
Decrease turnaround time on disputes and payments.
Improve collaboration between operations and accounting teams.
Provide a trail that connects compliance performance with financial outcomes.
Supplier One really compliments the apps within Retail Link. It may be possible that Walmart invests more heavily in Supplier One as time moves on but for now using this app in conjunction with other apps is best practice.
Troubleshooting and Support in Supplier One
Even the most user-friendly systems come with a learning curve—and Supplier One is no exception. Most issues suppliers encounter are minor and deal with accessibility issues that can be resolved quickly. Below are the most common errors and how to fix them quickly, along with a few insider tips to help prevent future problems.
Can’t Log In or Access the Portal
Users who have issues logging in to Supplier One should start by confirming the use of the correct Retail Link credentials. Supplier One is part of Walmart’s app ecosystem, so the login is tied directly to the Retail Link account.
Pro Tip: Access issues are usually tied to expired credentials or administrator settings which can be resolved by contact Retail Link Help Desk at: rlshelp@walmart.com
Missing Vendor Numbers or Incomplete Data
Incomplete and missing data within Supplier One usually means vendor records haven’t been synced correctly between Walmart’s internal systems and the supplier’s Retail Link account. This is a data refresh issue and not a permissions problem.
Suppliers can verify vendor numbers by navigating to Apps, then Supplier One, then Vendor Summary. Compare what appears there with the vendor number listed under the Retail Link Supplier Information Report.
Payments or Invoices Not Appearing
If payments or invoices aren't in Supplier One, suppliers should first check for missing supplier bank details. Then, check to ensure invoices are properly posted to the general ledger and try running reports like "Unpaid Invoice Details" in the "Reports" section. Other issues include incorrect payment categorization and errors in the system that can be verified by contacting the Retail Link help desk at: rlshelp@walmart.com
Upload or File Attachment Error
These issues are common and often due to missing required fields, incorrect file formats, or size limits. To fix, users should review the error details in the submission spreadsheet, check the file specifications (like file type, size, and name), ensure all required fields are complete, and try to upload again. If the problem persists, contact support for assistance.
Pro Tip: Suppliers should use clear file naming conventions such as: PO12345_BOL or Invoice_987654_POD. Walmart analysts process tickets faster when documentation is easy to identify.
Key Takeaways
Supplier One is Walmart’s financial command center. It consolidates payments, invoices, and communication into one intuitive hub—offering real time visibility that Retail Link alone doesn’t provide.
The apps within Retail Link are complimentary to Supplier One, not competitive. Retail Link drives operational and compliance data, while Supplier One handles financial transparency. Together they create a complete picture of profitability.
Use Supplier One as a top-level view, APIS for remittance verification, and APDP to resolve deductions. This connected workflow prevents missed disputes and accelerates revenue recovery.
Proactive review reduces deductions and delays. Checking Supplier One regularly for payment status and other important information keeps cash flow steady and compliance records clean.
Supplier One represents the next phase of Walmart’s digital supplier evolution. It bridges the operational insights of Retail Link with the financial accountability of APDP and APIS, giving suppliers one clear view from purchase to payment.
